+*Thanks for taking the time to report this build failure. To proceed with the
+report please:*
+1. Title the issue "Installation issue: <name-of-the-package>".
+2. Provide the information required below.
+3. Remove the template instructions before posting the issue.
+
+We encourage you to try, as much as possible, to reduce your problem to the minimal example that still reproduces the issue. That would help us a lot in fixing it quickly and effectively!
+
+
+---
+
+### Steps to reproduce the issue
+
+```console
+$ spack install <spec> # Fill in the exact spec you are using
+... # and the relevant part of the error message
+```
+
+### Platform and user environment
+
+Please report your OS here:
+```commandline
+$ uname -a 
+Linux nuvolari 4.15.0-29-generic #31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
+$ lsb_release -d
+Description:	Ubuntu 18.04.1 LTS
+``` 
+and, if relevant, post or attach:
+
+- `packages.yaml`
+- `compilers.yaml`
+
+to the issue
+
+### Additional information
+
+Sometimes the issue benefits from additional details. In these cases there are
+a few things we can suggest doing. First of all, you can post the full output of:
+```console
+$ spack spec --install-status <spec>
+...
+```
+to show people whether Spack installed a faulty software or if it was not able to
+build it at all. 
+
+If your build didn't make it past the configure stage, Spack as also commands to parse 
+logs and report error and warning messages:
+```console
+$ spack log-parse --show=errors,warnings <file-to-parse>
+```
+You might want to run this command on the `config.log` or any other similar file
+found in the stage directory: 
+```console
+$ spack location -s <spec>
+```
+In case in `config.log` there are other settings that you think might be the cause 
+of the build failure, you can consider attaching the file to this issue.
+
+Rebuilding the package with the following options:
+```console
+$ spack -d install -j 1 <spec>
+...
+```
+will provide additional debug information. After the failure you will find two files in the current directory:
+
+1. `spack-cc-<spec>.in`, which contains details on the command given in input 
+    to Spack's compiler wrapper  
+1. `spack-cc-<spec>.out`, which contains the command used to compile / link the 
+    failed object after Spack's compiler wrapper did its processing 
+
+You can post or attach those files to provide maintainers with more information on what
+is causing the failure.

-title: "The Spack Package Manager: Bringing Order to HPC Software Chaos"
-abstract: >-
-  Large HPC centers spend considerable time supporting software for thousands of users, but the
-  complexity of HPC software is quickly outpacing the capabilities of existing software management
-  tools. Scientific applications require specific versions of compilers, MPI, and other dependency
-  libraries, so using a single, standard software stack is infeasible. However, managing many
-  configurations is difficult because the configuration space is combinatorial in size. We
-  introduce Spack, a tool used at Lawrence Livermore National Laboratory to manage this complexity.
-  Spack provides a novel, re- cursive specification syntax to invoke parametric builds of packages
-  and dependencies. It allows any number of builds to coexist on the same system, and it ensures
-  that installed packages can find their dependencies, regardless of the environment. We show
-  through real-world use cases that Spack supports diverse and demanding applications, bringing
-  order to HPC software chaos.

-Spack's `develop` branch has the latest contributions. Pull requests
-should target `develop`, and users who want the latest package versions,
-features, etc. can use `develop`.
-
-Releases
---------
-
-For multi-user site deployments or other use cases that need very stable
-software installations, we recommend using Spack's
-[stable releases](https://github.com/spack/spack/releases).
-
-Each Spack release series also has a corresponding branch, e.g.
-`releases/v0.14` has `0.14.x` versions of Spack, and `releases/v0.13` has
-`0.13.x` versions. We backport important bug fixes to these branches but
-we do not advance the package versions or make other changes that would
-change the way Spack concretizes dependencies within a release branch.
-So, you can base your Spack deployment on a release branch and `git pull`
-to get fixes, without the package churn that comes with `develop`.
-
-The latest release is always available with the `releases/latest` tag.
-
-See the [docs on releases](https://spack.readthedocs.io/en/latest/developer_guide.html#releases)
-for more details.
+Spack uses a rough approximation of the
+[Git Flow](http://nvie.com/posts/a-successful-git-branching-model/)
+branching model.  The ``develop`` branch contains the latest
+contributions, and ``master`` is always tagged and points to the latest
+stable release.

 # `sbang`: Run scripts with long shebang lines.
 #

+# Many operating systems limit the length of shebang lines, making it
+# hard to use interpreters that are deep in the directory hierarchy.
+# `sbang` can run such scripts, either as a shebang interpreter, or
+# directly on the command line.
 #
-# To use, put the long shebang on the second line of your script, and
-# make sbang the interpreter, like this:
+# Usage
+# -----------------------------
+# Suppose you have a script, long-shebang.sh, like this:
 #
-#     #!/bin/sh /path/to/sbang
-#     #!/long/path/to/real/interpreter with arguments
+#     1    #!/very/long/path/to/some/interpreter
+#     2
+#     3    echo "success!"
 #
-# `sbang` will run the real interpreter with the script as its argument.
+# Invoking this script will result in an error on some OS's.  On
+# Linux, you get this:
 #
-# See https://github.com/spack/sbang for more details.
+#     $ ./long-shebang.sh
+#     -bash: ./long: /very/long/path/to/some/interp: bad interpreter:
+#            No such file or directory
+#
+# On Mac OS X, the system simply assumes the interpreter is the shell
+# and tries to run with it, which is likely not what you want.
+#
+#
+# `sbang` on the command line
+# -----------------------------
+# You can use `sbang` in two ways.  The first is to use it directly,
+# from the command line, like this:
+#
+#     $ sbang ./long-shebang.sh
+#     success!
+#
+#
+# `sbang` as the interpreter
+# -----------------------------
+# You can also use `sbang` *as* the interpreter for your script. Put
+# `#!/bin/bash /path/to/sbang` on line 1, and move the original
+# shebang to line 2 of the script:
+#
+#     1    #!/bin/bash /path/to/sbang
+#     2    #!/long/path/to/real/interpreter with arguments
+#     3
+#     4    echo "success!"
+#
+#     $ ./long-shebang.sh
+#     success!
+#
+# On Linux, you could shorten line 1 to `#!/path/to/sbang`, but other
+# operating systems like Mac OS X require the interpreter to be a
+# binary, so it's best to use `sbang` as a `bash` argument.
+# Obviously, for this to work, `sbang` needs to have a short enough
+# path that *it* will run without hitting OS limits.
+#
+# For Lua, scripts the second line can't start with #!, as # is not
+# the comment character in lua (even though lua ignores #! on the
+# *first* line of a script).  So, instrument a lua script like this,
+# using -- instead of # on the second line:
+#
+#     1    #!/bin/bash /path/to/sbang
+#     2    --!/long/path/to/lua with arguments
+#     3
+#     4    print "success!"
+#
+# How it works
+# -----------------------------
+# `sbang` is a very simple bash script. It looks at the first two
+# lines of a script argument and runs the last line starting with
+# `#!`, with the script as an argument. It also forwards arguments.

-:: This file is part of Spack and sets up the spack environment for batch,
-:: This includes environment modules and lmod support,

-:: This is a wrapper around the spack command that forwards calls to
-:: 'spack load' and 'spack unload' to shell functions.  This in turn
-:: allows them to be used to invoke environment modules functions.
-::
-:: 'spack load' is smarter than just 'load' because it converts its
-:: arguments into a unique Spack spec that is then passed to module
-:: commands.  This allows the user to use packages without knowing all
-:: their installation details.
-::
-:: e.g., rather than requiring a full spec for libelf, the user can type:
-::
-::     spack load libelf
-::
-:: This will first find the available libelf module file and use a
-:: matching one.  If there are two versions of libelf, the user would
-:: need to be more specific, e.g.:
-::
-::     spack load libelf@0.8.13
-::
-:: This is very similar to how regular spack commands work and it
-:: avoids the need to come up with a user-friendly naming scheme for
-:: spack module files.

-Creating a build cache
-----------------------
+A compressed tarball of an installed package is created. Tarballs are created
+for all of its link and run dependency packages as well. Compressed tarballs are
+signed with gpg and signature and tarball and put in a ``.spack`` file. Optionally,
+the rpaths (and ids and deps on macOS) can be changed to paths relative to
+the Spack install tree before the tarball is created.
 
 Build caches are created via:
 
 .. code-block:: console
 
-    $ spack buildcache push <path/url/mirror name> <spec>
+   $ spack buildcache create spec
 
-This command takes the locally installed spec and its dependencies, and
-creates tarballs of their install prefixes. It also generates metadata files,
-signed with GPG. These tarballs and metadata files are then pushed to the
-provided binary cache, which can be a local directory or a remote URL.
-
-Here is an example where a build cache is created in a local directory named
-"spack-cache", to which we push the "ninja" spec:
-
-.. code-block:: console
-
-    $ spack buildcache push ./spack-cache ninja
-    ==> Pushing binary packages to file:///home/spackuser/spack/spack-cache/build_cache

-It worked! You've just completed a full example of creating a build cache with
-a spec of interest, adding it as a mirror, updating its index, listing the contents,
-and finally, installing from it.
-
-By default Spack falls back to building from sources when the mirror is not available
-or when the package is simply not already available. To force Spack to only install
-prebuilt packages, you can use
-
-.. code-block:: console
-
-   $ spack install --use-buildcache only <package>
-
-For example, to combine all of the commands above to add the E4S build cache
-and then install from it exclusively, you would do:
-
-.. code-block:: console
-
-    $ spack mirror add E4S https://cache.e4s.io
-    $ spack buildcache keys --install --trust
-    $ spack install --use-buildcache only <package>
-
-We use ``--install`` and ``--trust`` to say that we are installing keys to our
-keyring, and trusting all downloaded keys.

-
--------------------
-Build cache signing
--------------------
-
-By default, Spack will add a cryptographic signature to each package pushed to
-a build cache, and verifies the signature when installing from a build cache.
-
-Keys for signing can be managed with the :ref:`spack gpg <cmd-spack-gpg>` command,
-as well as ``spack buildcache keys`` as mentioned above.
-
-You can disable signing when pushing with ``spack buildcache push --unsigned``,
-and disable verification when installing from any build cache with
-``spack install --no-check-signature``.
-
-Alternatively, signing and verification can be enabled or disabled on a per build cache
-basis:
-
-.. code-block:: console
-
-    $ spack mirror add --signed <name> <url>  # enable signing and verification
-    $ spack mirror add --unsigned <name> <url>  # disable signing and verification
-
-    $ spack mirror set --signed <name>  # enable signing and verification for an existing mirror
-    $ spack mirror set --unsigned <name>  # disable signing and verification for an existing mirror
-
-Or you can directly edit the ``mirrors.yaml`` configuration file:
-
-.. code-block:: yaml
-
-    mirrors:
-      <name>:
-        url: <url>
-        signed: false # disable signing and verification
-
-See also :ref:`mirrors`.
 
 ----------
 Relocation
 ----------
 
-When using buildcaches across different machines, it is likely that the install
-root will be different from the one used to build the binaries.
-
-To address this issue, Spack automatically relocates all paths encoded in binaries
-and scripts to their new location upon install.
-
-Note that there are some cases where this is not possible: if binaries are built in
-a relatively short path, and then installed to a longer path, there may not be enough
-space in the binary to encode the new path. In this case, Spack will fail to install
-the package from the build cache, and a source build is required.
-
-To reduce the likelihood of this happening, it is highly recommended to add padding to
-the install root during the build, as specified in the :ref:`config <config-yaml>`
-section of the configuration:
-
-.. code-block:: yaml
-
-   config:
-     install_tree:
-       root: /opt/spack
-       padded_length: 128
-
-
-.. _binary_caches_oci:
-
----------------------------------
-Automatic push to a build cache
----------------------------------
-
-Sometimes it is convenient to push packages to a build cache as soon as they are installed. Spack can do this by setting autopush flag when adding a mirror:
-
-.. code-block:: console
-
-    $ spack mirror add --autopush <name> <url or path>
-
-Or the autopush flag can be set for an existing mirror:
-
-.. code-block:: console
-
-    $ spack mirror set --autopush <name>  # enable automatic push for an existing mirror
-    $ spack mirror set --no-autopush <name>  # disable automatic push for an existing mirror
-
-Then after installing a package it is automatically pushed to all mirrors with ``autopush: true``. The command
-
-.. code-block:: console
-
-    $ spack install <package>
-
-will have the same effect as
-
-.. code-block:: console
-
-    $ spack install <package>
-    $ spack buildcache push <cache> <package>  # for all caches with autopush: true
-
-.. note::
-
-    Packages are automatically pushed to a build cache only if they are built from source.
-
------------------------------------------
-OCI / Docker V2 registries as build cache
------------------------------------------
-
-Spack can also use OCI or Docker V2 registries such as Dockerhub, Quay.io,
-Github Packages, GitLab Container Registry, JFrog Artifactory, and others
-as build caches. This is a convenient way to share binaries using public
-infrastructure, or to cache Spack built binaries in Github Actions and
-GitLab CI.
-
-To get started, configure an OCI mirror using ``oci://`` as the scheme,
-and optionally specify variables that hold the username and password (or
-personal access token) for the registry:
-
-.. code-block:: console
-
-    $ spack mirror add --oci-username-variable REGISTRY_USER \
-                       --oci-password-variable REGISTRY_TOKEN \
-                       my_registry oci://example.com/my_image
-
-Spack follows the naming conventions of Docker, with Dockerhub as the default
-registry. To use Dockerhub, you can omit the registry domain:
-
-.. code-block:: console
-
-    $ spack mirror add ... my_registry oci://username/my_image
-
-From here, you can use the mirror as any other build cache:
-
-.. code-block:: console
-
-    $ export REGISTRY_USER=...
-    $ export REGISTRY_TOKEN=...
-    $ spack buildcache push my_registry <specs...>  # push to the registry
-    $ spack install <specs...>  # or install from the registry
-
-A unique feature of buildcaches on top of OCI registries is that it's incredibly
-easy to generate get a runnable container image with the binaries installed. This
-is a great way to make applications available to users without requiring them to
-install Spack -- all you need is Docker, Podman or any other OCI-compatible container
-runtime.
-
-To produce container images, all you need to do is add the ``--base-image`` flag
-when pushing to the build cache:
-
-.. code-block:: console
-
-    $ spack buildcache push --base-image ubuntu:20.04 my_registry ninja
-    Pushed to example.com/my_image:ninja-1.11.1-yxferyhmrjkosgta5ei6b4lqf6bxbscz.spack
-
-    $ docker run -it example.com/my_image:ninja-1.11.1-yxferyhmrjkosgta5ei6b4lqf6bxbscz.spack
-    root@e4c2b6f6b3f4:/# ninja --version
-    1.11.1
-
-If ``--base-image`` is not specified, distroless images are produced. In practice,
-you won't be able to run these as containers, since they don't come with libc and
-other system dependencies. However, they are still compatible with tools like
-``skopeo``, ``podman``, and ``docker`` for pulling and pushing.
-
-.. note::
-    The docker ``overlayfs2`` storage driver is limited to 128 layers, above which a
-    ``max depth exceeded`` error may be produced when pulling the image. There
-    are `alternative drivers <https://docs.docker.com/storage/storagedriver/>`_.

-Spack build cache for GitHub Actions
-------------------------------------
-
-To significantly speed up Spack in GitHub Actions, binaries can be cached in
-GitHub Packages. This service is an OCI registry that can be linked to a GitHub
-repository.
-
-Spack offers a public build cache for GitHub Actions with a set of common packages,
-which lets you get started quickly. See the following resources for more information:
-
-* `spack/setup-spack <https://github.com/spack/setup-spack>`_ for setting up Spack in GitHub
-  Actions

+Initial build and later installation do not necessarily happen at the same
+location. Spack provides a relocation capability and corrects for RPATHs and
+non-relocatable scripts. However, many packages compile paths into binary
+artifacts directly. In such cases, the build instructions of this package would
+need to be adjusted for better re-locatability.

-is an entire command dedicated to the management of every aspect of bootstrapping:
-
-.. command-output:: spack bootstrap --help
-
-Spack is configured to bootstrap its dependencies lazily by default; i.e. the first time they are needed and
-can't be found. You can readily check if any prerequisite for using Spack is missing by running:
-
-.. code-block:: console
-
-   % spack bootstrap status
-   Spack v0.19.0 - python@3.8
-
-   [FAIL] Core Functionalities
-     [B] MISSING "clingo": required to concretize specs
-
-   [FAIL] Binary packages
-     [B] MISSING "gpg2": required to sign/verify buildcaches
-
-
-   Spack will take care of bootstrapping any missing dependency marked as [B]. Dependencies marked as [-] are instead required to be found on the system.
-
-   % echo $?
-   1
-
-In the case of the output shown above Spack detected that both ``clingo`` and ``gnupg``
-are missing and it's giving detailed information on why they are needed and whether
-they can be bootstrapped. The return code of this command summarizes the results, if any
-dependencies are missing the return code is ``1``, otherwise ``0``. Running a command that

-   % spack bootstrap root
-
-It can also be changed with the same command by just specifying the newly desired path:

-
-   % spack bootstrap root /opt/spack/bootstrap
-
-You can check what is installed in the bootstrapping store at any time using:
-
-.. code-block:: console
-
-   % spack -b find
-   ==> Showing internal bootstrap store at "/Users/spack/.spack/bootstrap/store"

-
-In case it is needed you can remove all the software in the current bootstrapping store with:

-   % spack clean -b
-   ==> Removing bootstrapped software and configuration in "/Users/spack/.spack/bootstrap"

-Enabling and disabling bootstrapping methods
---------------------------------------------
-
-Bootstrapping is always performed by trying the methods listed by:
-
-.. command-output:: spack bootstrap list
-
-in the order they appear, from top to bottom. By default Spack is
-configured to try first bootstrapping from pre-built binaries and to
-fall-back to bootstrapping from sources if that failed.
-
-If need be, you can disable bootstrapping altogether by running:
-
-.. code-block:: console
-
-   % spack bootstrap disable
-
-in which case it's your responsibility to ensure Spack runs in an
-environment where all its prerequisites are installed. You can
-also configure Spack to skip certain bootstrapping methods by disabling
-them specifically:
-
-.. code-block:: console
-
-   % spack bootstrap disable github-actions
-   ==> "github-actions" is now disabled and will not be used for bootstrapping
-
-tells Spack to skip trying to bootstrap from binaries. To add the "github-actions" method back you can:
-
-.. code-block:: console
-
-   % spack bootstrap enable github-actions
-
-There is also an option to reset the bootstrapping configuration to Spack's defaults:
-
-.. code-block:: console
-
-   % spack bootstrap reset
-   ==> Bootstrapping configuration is being reset to Spack's defaults. Current configuration will be lost.
-   Do you want to continue? [Y/n]
-   %
-
-----------------------------------------
-Creating a mirror for air-gapped systems
-----------------------------------------
-
-Spack's default configuration for bootstrapping relies on the user having
-access to the internet, either to fetch pre-compiled binaries or source tarballs.
-Sometimes though Spack is deployed on air-gapped systems where such access is denied.
-
-To help with similar situations Spack has a command that recreates, in a local folder
-of choice, a mirror containing the source tarballs and/or binary packages needed for
-bootstrapping.
-
-.. code-block:: console
-
-   % spack bootstrap mirror --binary-packages /opt/bootstrap
-   ==> Adding "clingo-bootstrap@spack+python %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
-   ==> Adding "gnupg@2.3: %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
-   ==> Adding "patchelf@0.13.1:0.13.99 %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
-   ==> Adding binary packages from "https://github.com/alalazo/spack-bootstrap-mirrors/releases/download/v0.1-rc.2/bootstrap-buildcache.tar.gz" to the mirror at /opt/bootstrap/local-mirror
-
-   To register the mirror on the platform where it's supposed to be used run the following command(s):
-     % spack bootstrap add --trust local-sources /opt/bootstrap/metadata/sources
-     % spack bootstrap add --trust local-binaries /opt/bootstrap/metadata/binaries
-     % spack buildcache update-index /opt/bootstrap/bootstrap_cache
-
-This command needs to be run on a machine with internet access and the resulting folder
-has to be moved over to the air-gapped system. Once the local sources are added using the
-commands suggested at the prompt, they can be used to bootstrap Spack.

+or you can make it prefer to build with particular compilers.  You can
+also tell Spack to use *external* software installations already
+present on your system.
 
-The ``concretizer.yaml`` configuration file allows to customize aspects of the
-algorithm used to select the dependencies you install. The default configuration
-is the following:
-
-.. literalinclude:: _spack_root/etc/spack/defaults/concretizer.yaml
-   :language: yaml
-
---------------------------------
-Reuse already installed packages
---------------------------------
-
-The ``reuse`` attribute controls how aggressively Spack reuses binary packages during concretization. The
-attribute can either be a single value, or an object for more complex configurations.
-
-In the former case ("single value") it allows Spack to:
-
-1. Reuse installed packages and buildcaches for all the specs to be concretized, when ``true``
-2. Reuse installed packages and buildcaches only for the dependencies of the root specs, when ``dependencies``
-3. Disregard reusing installed packages and buildcaches, when ``false``
-
-In case a finer control over which specs are reused is needed, then the value of this attribute can be
-an object, with the following keys:
-
-1. ``roots``: if ``true`` root specs are reused, if ``false`` only dependencies of root specs are reused
-2. ``from``: list of sources from which reused specs are taken
-
-Each source in ``from`` is itself an object:
-
-.. list-table:: Attributes for a source or reusable specs
-   :header-rows: 1
-
-   * - Attribute name
-     - Description
-   * - type (mandatory, string)
-     - Can be ``local``, ``buildcache``, or ``external``
-   * - include (optional, list of specs)
-     - If present, reusable specs must match at least one of the constraint in the list
-   * - exclude (optional, list of specs)
-     - If present, reusable specs must not match any of the constraint in the list.
-
-For instance, the following configuration:
+At a high level, the ``packages.yaml`` file is structured like this:
 
 .. code-block:: yaml
 
-   concretizer:
-     reuse:
-       roots: true
-       from:
-       - type: local
-         include:
-         - "%gcc"
-         - "%clang"
+   packages:
+     package1:
+       # settings for package1
+     package2:
+       # settings for package2
+     # ...
+     all:
+       # settings that apply to all packages.
 
-tells the concretizer to reuse all specs compiled with either ``gcc`` or ``clang``, that are installed
-in the local store. Any spec from remote buildcaches is disregarded.
+So you can either set build preferences specifically for *one* package,
+or you can specify that certain settings should apply to *all* packages.
+The types of settings you can customize are described in detail below.
 
-To reduce the boilerplate in configuration files, default values for the ``include`` and
-``exclude`` options can be pushed up one level:
+Spack's build defaults are in the default
+``etc/spack/defaults/packages.yaml`` file.  You can override them in
+``~/.spack/packages.yaml`` or ``etc/spack/packages.yaml``. For more
+details on how this works, see :ref:`configuration-scopes`.
+
+.. _sec-external-packages:
+
+-----------------
+External Packages
+-----------------
+
+Spack can be configured to use externally-installed
+packages rather than building its own packages. This may be desirable
+if machines ship with system packages, such as a customized MPI
+that should be used instead of Spack building its own MPI.
+
+External packages are configured through the ``packages.yaml`` file found
+in a Spack installation's ``etc/spack/`` or a user's ``~/.spack/``
+directory. Here's an example of an external configuration:
 
 .. code-block:: yaml
 
-   concretizer:
-     reuse:
-       roots: true
-       include:
-       - "%gcc"
-       from:
-       - type: local
-       - type: buildcache
-       - type: local
-         include:
-         - "foo %oneapi"
+   packages:
+     openmpi:
+       paths:
+         openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64: /opt/openmpi-1.4.3
+         openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug: /opt/openmpi-1.4.3-debug
+         openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64: /opt/openmpi-1.6.5-intel
 
-In the example above we reuse all specs compiled with ``gcc`` from the local store
-and remote buildcaches, and we also reuse ``foo %oneapi``. Note that the last source of
-specs override the default ``include`` attribute.
+This example lists three installations of OpenMPI, one built with GCC,
+one built with GCC and debug information, and another built with Intel.
+If Spack is asked to build a package that uses one of these MPIs as a
+dependency, it will use the pre-installed OpenMPI in
+the given directory. Note that the specified path is the top-level
+install prefix, not the ``bin`` subdirectory.
 
-For one-off concretizations, the are command line arguments for each of the simple "single value"
-configurations. This means a user can:
-
-.. code-block:: console
-
-   % spack install --reuse <spec>
-
-to enable reuse for a single installation, or:
-
-.. code-block:: console
-
-   spack install --fresh <spec>
-
-to do a fresh install if ``reuse`` is enabled by default.
-
-.. seealso::
-
-   FAQ: :ref:`Why does Spack pick particular versions and variants? <faq-concretizer-precedence>`
-
-------------------------------------------
-Selection of the target microarchitectures
-------------------------------------------
-
-The options under the ``targets`` attribute control which targets are considered during a solve.
-Currently the options in this section are only configurable from the ``concretizer.yaml`` file
-and there are no corresponding command line arguments to enable them for a single solve.
-
-The ``granularity`` option can take two possible values: ``microarchitectures`` and ``generic``.
-If set to:
+``packages.yaml`` can also be used to specify modules to load instead
+of the installation prefixes.  The following example says that module
+``CMake/3.7.2`` provides cmake version 3.7.2.
 
 .. code-block:: yaml
 
-   concretizer:
-     targets:
-       granularity: microarchitectures
+   cmake:
+     modules:
+       cmake@3.7.2: CMake/3.7.2
 
-Spack will consider all the microarchitectures known to ``archspec`` to label nodes for
-compatibility. If instead the option is set to:
+Each ``packages.yaml`` begins with a ``packages:`` token, followed
+by a list of package names.  To specify externals, add a ``paths`` or ``modules``
+token under the package name, which lists externals in a
+``spec: /path`` or ``spec: module-name`` format.  Each spec should be as
+well-defined as reasonably possible.  If a
+package lacks a spec component, such as missing a compiler or
+package version, then Spack will guess the missing component based
+on its most-favored packages, and it may guess incorrectly.
+
+Each package version and compiler listed in an external should
+have entries in Spack's packages and compiler configuration, even
+though the package and compiler may not ever be built.
+
+The packages configuration can tell Spack to use an external location
+for certain package versions, but it does not restrict Spack to using
+external packages.  In the above example, since newer versions of OpenMPI
+are available, Spack will choose to start building and linking with the
+latest version rather than continue using the pre-installed OpenMPI versions.
+
+To prevent this, the ``packages.yaml`` configuration also allows packages
+to be flagged as non-buildable.  The previous example could be modified to
+be:
 
 .. code-block:: yaml
 
-   concretizer:
-     targets:
-       granularity: generic
+   packages:
+     openmpi:
+       paths:
+         openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64: /opt/openmpi-1.4.3
+         openmpi@1.4.3%gcc@4.4.7 arch=linux-debian7-x86_64+debug: /opt/openmpi-1.4.3-debug
+         openmpi@1.6.5%intel@10.1 arch=linux-debian7-x86_64: /opt/openmpi-1.6.5-intel
+       buildable: False
 
-Spack will consider only generic microarchitectures. For instance, when running on an
-Haswell node, Spack will consider ``haswell`` as the best target in the former case and
-``x86_64_v3`` as the best target in the latter case.
+The addition of the ``buildable`` flag tells Spack that it should never build
+its own version of OpenMPI, and it will instead always rely on a pre-built
+OpenMPI.  Similar to ``paths``, ``buildable`` is specified as a property under
+a package name.
 
-The ``host_compatible`` option is a Boolean option that determines whether or not the
-microarchitectures considered during the solve are constrained to be compatible with the
-host Spack is currently running on. For instance, if this option is set to ``true``, a
-user cannot concretize for ``target=icelake`` while running on an Haswell node.
+If an external module is specified as not buildable, then Spack will load the
+external module into the build environment which can be used for linking.
 
----------------
-Duplicate nodes
----------------
+The ``buildable`` does not need to be paired with external packages.
+It could also be used alone to forbid packages that may be
+buggy or otherwise undesirable.
 
-The ``duplicates`` attribute controls whether the DAG can contain multiple configurations of
-the same package. This is mainly relevant for build dependencies, which may have their version
-pinned by some nodes, and thus be required at different versions by different nodes in the same
-DAG.
 
-The ``strategy`` option controls how the solver deals with duplicates. If the value is ``none``,
-then a single configuration per package is allowed in the DAG. This means, for instance, that only
-a single ``cmake`` or a single ``py-setuptools`` version is allowed. The result would be a slightly
-faster concretization, at the expense of making a few specs unsolvable.
+.. _concretization-preferences:
 
-If the value is ``minimal`` Spack will allow packages tagged as ``build-tools`` to have duplicates.
-This allows, for instance, to concretize specs whose nodes require different, and incompatible, ranges
-of some build tool. For instance, in the figure below the latest `py-shapely` requires a newer `py-setuptools`,
-while `py-numpy` still needs an older version:
+--------------------------
+Concretization Preferences
+--------------------------
 
-.. figure::  images/shapely_duplicates.svg
-   :scale: 70 %
-   :align: center
+Spack can be configured to prefer certain compilers, package
+versions, dependencies, and variants during concretization.
+The preferred configuration can be controlled via the
+``~/.spack/packages.yaml`` file for user configurations, or the
+``etc/spack/packages.yaml`` site configuration.
 
-Up to Spack v0.20 ``duplicates:strategy:none`` was the default (and only) behavior. From Spack v0.21 the
-default behavior is ``duplicates:strategy:minimal``.
-
---------
-Splicing
---------
-
-The ``splice`` key covers config attributes for splicing specs in the solver.
-
-"Splicing" is a method for replacing a dependency with another spec
-that provides the same package or virtual. There are two types of
-splices, referring to different behaviors for shared dependencies
-between the root spec and the new spec replacing a dependency:
-"transitive" and "intransitive". A "transitive" splice is one that
-resolves all conflicts by taking the dependency from the new node. An
-"intransitive" splice is one that resolves all conflicts by taking the
-dependency from the original root. From a theory perspective, hybrid
-splices are possible but are not modeled by Spack.
-
-All spliced specs retain a ``build_spec`` attribute that points to the
-original Spec before any splice occurred. The ``build_spec`` for a
-non-spliced spec is itself.
-
-The figure below shows examples of transitive and intransitive splices:
-
-.. figure:: images/splices.png
-   :align: center
-
-The concretizer can be configured to explicitly splice particular
-replacements for a target spec. Splicing will allow the user to make
-use of generically built public binary caches, while swapping in
-highly optimized local builds for performance critical components
-and/or components that interact closely with the specific hardware
-details of the system. The most prominent candidate for splicing is
-MPI providers. MPI packages have relatively well-understood ABI
-characteristics, and most High Performance Computing facilities deploy
-highly optimized MPI packages tailored to their particular
-hardware. The following config block configures Spack to replace
-whatever MPI provider each spec was concretized to use with the
-particular package of ``mpich`` with the hash that begins ``abcdef``.
+Here's an example ``packages.yaml`` file that sets preferred packages:
 
 .. code-block:: yaml
 
-   concretizer:
-     splice:
-       explicit:
-       - target: mpi
-         replacement: mpich/abcdef
-         transitive: false
+   packages:
+     opencv:
+       compiler: [gcc@4.9]
+       variants: +debug
+     gperftools:
+       version: [2.2, 2.4, 2.3]
+     all:
+       compiler: [gcc@4.4.7, 'gcc@4.6:', intel, clang, pgi]
+       target: [sandybridge]
+       providers:
+         mpi: [mvapich2, mpich, openmpi]
 
-.. warning::
+At a high level, this example is specifying how packages should be
+concretized.  The opencv package should prefer using GCC 4.9 and
+be built with debug options.  The gperftools package should prefer version
+2.2 over 2.4.  Every package on the system should prefer mvapich2 for
+its MPI and GCC 4.4.7 (except for opencv, which overrides this by preferring GCC 4.9).
+These options are used to fill in implicit defaults.  Any of them can be overwritten
+on the command line if explicitly requested.
 
-   When configuring an explicit splice, you as the user take on the
-   responsibility for ensuring ABI compatibility between the specs
-   matched by the target and the replacement you provide. If they are
-   not compatible, Spack will not warn you and your application will
-   fail to run.
+Each ``packages.yaml`` file begins with the string ``packages:`` and
+package names are specified on the next level. The special string ``all``
+applies settings to *all* packages. Underneath each package name is one
+or more components: ``compiler``, ``variants``, ``version``,
+``providers``, and ``target``.  Each component has an ordered list of
+spec ``constraints``, with earlier entries in the list being preferred
+over later entries.
 
-The ``target`` field of an explicit splice can be any abstract
-spec. The ``replacement`` field must be a spec that includes the hash
-of a concrete spec, and the replacement must either be the same
-package as the target, provide the virtual that is the target, or
-provide a virtual that the target provides. The ``transitive`` field
-is optional -- by default, splices will be transitive.
+Sometimes a package installation may have constraints that forbid
+the first concretization rule, in which case Spack will use the first
+legal concretization rule.  Going back to the example, if a user
+requests gperftools 2.3 or later, then Spack will install version 2.4
+as the 2.4 version of gperftools is preferred over 2.3.
 
-.. note::
+An explicit concretization rule in the preferred section will always
+take preference over unlisted concretizations.  In the above example,
+xlc isn't listed in the compiler list.  Every listed compiler from
+gcc to pgi will thus be preferred over the xlc compiler.
 
-   With explicit splices configured, it is possible for Spack to
-   concretize to a spec that does not satisfy the input. For example,
-   with the config above ``hdf5 ^mvapich2`` will concretize to user
-   ``mpich/abcdef`` instead of ``mvapich2`` as the MPI provider. Spack
-   will warn the user in this case, but will not fail the
-   concretization.
+The syntax for the ``provider`` section differs slightly from other
+concretization rules.  A provider lists a value that packages may
+``depend_on`` (e.g, MPI) and a list of rules for fulfilling that
+dependency.

-Automatic Splicing
-^^^^^^^^^^^^^^^^^^
+-------------------
+Package Permissions
+-------------------
 
-The Spack solver can be configured to do automatic splicing for
-ABI-compatible packages. Automatic splices are enabled in the concretizer
-config section
+Spack can be configured to assign permissions to the files installed
+by a package.
+
+In the ``packages.yaml`` file under ``permissions``, the attributes
+``read``, ``write``, and ``group`` control the package
+permissions. These attributes can be set per-package, or for all
+packages under ``all``. If permissions are set under ``all`` and for a
+specific package, the package-specific settings take precedence.
+
+The ``read`` and ``write`` attributes take one of ``user``, ``group``,
+and ``world``.
 
 .. code-block:: yaml
 
-   concretizer:
-     splice:
-       automatic: True
+  packages:
+    all:
+      permissions:
+        write: group
+        group: spack
+    my_app:
+      permissions:
+        read: group
+        group: my_team
 
-Packages can include ABI-compatibility information using the
-``can_splice`` directive. See :ref:`the packaging
-guide<abi_compatibility>` for instructions on specifying ABI
-compatibility using the ``can_splice`` directive.
+The permissions settings describe the broadest level of access to
+installations of the specified packages. The execute permissions of
+the file are set to the same level as read permissions for those files
+that are executable. The default setting for ``read`` is ``world``,
+and for ``write`` is ``user``. In the example above, installations of
+``my_app`` will be installed with user and group permissions but no
+world permissions, and owned by the group ``my_team``. All other
+packages will be installed with user and group write privileges, and
+world read privileges. Those packages will be owned by the group
+``spack``.
 
-.. note::
-
-   The ``can_splice`` directive is experimental and may be changed in
-   future versions.
-
-When automatic splicing is enabled, the concretizer will combine any
-number of ABI-compatible specs if possible to reuse installed packages
-and packages available from binary caches. The end result of these
-specs is equivalent to a series of transitive/intransitive splices,
-but the series may be non-obvious.
+The ``group`` attribute assigns a Unix-style group to a package. All
+files installed by the package will be owned by the assigned group,
+and the sticky group bit will be set on the install prefix and all
+directories inside the install prefix. This will ensure that even
+manually placed files within the install prefix are owned by the
+assigned group. If no group is assigned, Spack will allow the OS
+default behavior to go as expected.

-
-^^^^^^
-Phases
-^^^^^^
-
-The ``CachedCMakePackage`` base class comes with the following phases:
-
-#. ``initconfig`` - generate the CMake cache file
-#. ``cmake`` - generate the Makefile
-#. ``build`` - build the package
-#. ``install`` - install the package
-
-By default, these phases run:
-
-.. code-block:: console
-
-   $ mkdir spack-build
-   $ cd spack-build
-   $ cat << EOF > name-arch-compiler@version.cmake
-   # Write information on compilers and dependencies

-   $ cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/installation/prefix -C name-arch-compiler@version.cmake
-   $ make
-   $ make test  # optional
-   $ make install
-
-The ``CachedCMakePackage`` class inherits from the ``CMakePackage``
-class, and accepts all of the same options and adds all of the same
-flags to the ``cmake`` command. Similar to the ``CMakePAckage`` class,
-you may need to add a few arguments yourself, and the
-``CachedCMakePackage`` provides the same interface to add those
-flags.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Adding entries to the CMake cache
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-In addition to adding flags to the ``cmake`` command, you may need to
-add entries to the CMake cache in the ``initconfig`` phase. This can
-be done by overriding one of four methods:
-
-#. ``CachedCMakePackage.initconfig_compiler_entries``
-#. ``CachedCMakePackage.initconfig_mpi_entries``
-#. ``CachedCMakePackage.initconfig_hardware_entries``
-#. ``CachedCMakePackage.initconfig_package_entries``
-
-Each of these methods returns a list of CMake cache strings. The
-distinction between these methods is merely to provide a
-well-structured and legible cmake cache file -- otherwise, entries
-from each of these methods are handled identically.
-
-Spack also provides convenience methods for generating CMake cache
-entries. These methods are available at module scope in every Spack
-package. Because CMake parses boolean options, strings, and paths
-differently, there are three such methods:
-
-#. ``cmake_cache_option``
-#. ``cmake_cache_string``
-#. ``cmake_cache_path``
-
-These methods each accept three parameters -- the name of the CMake
-variable associated with the entry, the value of the entry, and an
-optional comment -- and return strings in the appropriate format to be
-returned from any of the ``initconfig*`` methods. Additionally, these
-methods may return comments beginning with the ``#`` character.
-
-A typical usage of these methods may look something like this:
-
-.. code-block:: python
-
-   def initconfig_mpi_entries(self):
-       # Get existing MPI configurations
-       entries = super(self, Foo).initconfig_mpi_entries()

-       # This spec has an MPI variant, and we need to enable MPI when it is on.
-       # This hypothetical package controls MPI with the ``FOO_MPI`` option to
-       # cmake.
-       if self.spec.satisfies("+mpi"):
-           entries.append(cmake_cache_option("FOO_MPI", True, "enable mpi"))

-``CMAKE_INSTALL_PREFIX``

-For troubleshooting cases where CMake fails to find a dependency, add the
-``--debug-find`` flag to ``cmake_args``.
-
-``CMAKE_BUILD_TYPE``

-CMake uses different RPATHs during the build and after installation, so that executables
-can locate the libraries they're linked to during the build, and installed executables
-do not have RPATHs to build directories. In Spack, we have to make sure that RPATHs are
-set properly after installation.
-
-Spack sets ``CMAKE_INSTALL_RPATH`` to a list of ``<prefix>/lib`` or ``<prefix>/lib64``
-directories of the spec's link-type dependencies. Apart from that, it sets
-``-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=ON``, which should add RPATHs for directories of
-linked libraries not in the directories covered by ``CMAKE_INSTALL_RPATH``.
-
-Usually it's enough to set only ``-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=ON``, but the
-reason to provide both options is that packages may dynamically open shared libraries,
-which CMake cannot detect. In those cases, the RPATHs from ``CMAKE_INSTALL_RPATH`` are
-used as search paths.
-
-.. note::
-
-   Some packages provide stub libraries, which contain an interface for linking without

+Provided variants and dependencies
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-^^^^^^^^
-Variants
-^^^^^^^^
-
-This package provides the following variants:
-
-* **cuda**
-
-  This variant is used to enable/disable building with ``CUDA``. The default
-  is disabled (or ``False``).
-
-* **cuda_arch**
-
-  This variant supports the optional specification of one or multiple architectures.
-  Valid values are maintained in the ``cuda_arch_values`` property and
-  are the numeric character equivalent of the compute capability version
-  (e.g., '10' for version 1.0). Each provided value affects associated
-  ``CUDA`` dependencies and compiler conflicts.
-  
-  The variant builds both PTX code for the _virtual_ architecture
-  (e.g. ``compute_10``) and binary code for the _real_ architecture (e.g. ``sm_10``).
-
-  GPUs and their compute capability versions are listed at
-  https://developer.nvidia.com/cuda-gpus .
-
-^^^^^^^^^
-Conflicts
-^^^^^^^^^
-
-Conflicts are used to prevent builds with known bugs or issues. While
-base ``CUDA`` conflicts have been included with this package, you may
-want to add more for your software.
-
-For example, if your package requires ``cuda_arch`` to be specified when
-``cuda`` is enabled, you can add the following conflict to your package
-to terminate such build attempts with a suitable message:
-
-.. code-block:: python
-
-    conflicts("cuda_arch=none", when="+cuda",
-              msg="CUDA architecture is required")
-
-Similarly, if your software does not support all versions of the property,
-you could add ``conflicts`` to your package for those versions.  For example,
-suppose your software does not work with CUDA compute capability versions
-prior to SM 5.0 (``50``).  You can add the following code to display a
-custom message should a user attempt such a build:
-
-.. code-block:: python
-
-    unsupported_cuda_archs = [
-        "10", "11", "12", "13",
-        "20", "21",
-        "30", "32", "35", "37"
-    ]
-    for value in unsupported_cuda_archs:
-        conflicts(f"cuda_arch={value}", when="+cuda",
-                  msg=f"CUDA architecture {value} is not supported")
-
-^^^^^^^
-Methods
-^^^^^^^
-
-This package provides one custom helper method, which is used to build
-standard CUDA compiler flags.
-
-**cuda_flags**
-
-    This built-in static method returns a list of command line flags
-    for the chosen ``cuda_arch`` value(s).  The flags are intended to
-    be passed to the CUDA compiler driver (i.e., ``nvcc``).
-
-    This method must be explicitly called when you are creating the
-    arguments for your build in order to use the values.
+``CudaPackage`` provides ``cuda`` variant (default to ``off``) to enable/disable
+``CUDA``, and ``cuda_arch`` variant to optionally specify the architecture.
+It also declares dependencies on the ``CUDA`` package ``depends_on('cuda@...')``
+based on the architecture as well as specifies conflicts for certain compiler versions.
 
 ^^^^^
 Usage
 ^^^^^
 
-This helper package can be added to your package by adding it as a base
-class of your package.  For example, you can add it to your
-:ref:`CMakePackage <cmakepackage>`-based package as follows:
+In order to use it, just add another base class to your package, for example:

-            ...
-            return args
-
-assuming only the ``WITH_CUDA`` and ``CUDA_FLAGS`` flags are required.
-You will need to customize options as needed for your build.
-
-This example also illustrates how to check for the ``cuda`` variant using
-``self.spec`` and how to retrieve the ``cuda_arch`` variant's value, which
-is a list, using ``self.spec.variants["cuda_arch"].value``.
-
-With over 70 packages using ``CudaPackage`` as of January 2021 there are
-lots of examples to choose from to get more ideas for using this package.

-oneAPI packages in Spack
-========================
-
-Spack can install and use the Intel oneAPI products. You may either
-use spack to install the oneAPI tools or use the `Intel
-installers`_. After installation, you may use the tools directly, or
-use Spack to build packages with the tools.
-
-The Spack Python class ``IntelOneapiPackage`` is a base class that is
-used by ``IntelOneapiCompilers``, ``IntelOneapiMkl``,
-``IntelOneapiTbb`` and other classes to implement the oneAPI
-packages. Search for ``oneAPI`` at `packages.spack.io <https://packages.spack.io>`_ for the full
-list of available oneAPI packages, or use::
-
-  spack list -d oneAPI
-
-For more information on a specific package, do::
-
-  spack info --all <package-name>
-
-Intel no longer releases new versions of Parallel Studio, which can be
-used in Spack via the :ref:`intelpackage`. All of its components can
-now be found in oneAPI.
-
-Examples
-========
-
-Building a Package With icx
----------------------------
-
-In this example, we build patchelf with ``icc`` and ``icx``. The
-compilers are installed with spack.
-
-Install the oneAPI compilers::
-
-  spack install intel-oneapi-compilers
-
-Add the compilers to your ``compilers.yaml`` so spack can use them::
-
-  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/bin
-
-Verify that the compilers are available::
-
-  spack compiler list
-
-Note that 2024 and later releases do not include ``icc``. Before 2024,
-the package layout was different::
-  
-  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/linux/bin/intel64
-  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/linux/bin
-
-The ``intel-oneapi-compilers`` package includes 2 families of
-compilers:
-
-* ``intel``: ``icc``, ``icpc``, ``ifort``. Intel's *classic*
-  compilers. 2024 and later releases contain ``ifort``, but not
-  ``icc`` and ``icpc``.
-* ``oneapi``: ``icx``, ``icpx``, ``ifx``. Intel's new generation of
-  compilers based on LLVM.
-
-To build the ``patchelf`` Spack package with ``icc``, do::
-
-  spack install patchelf%intel
-
-To build with with ``icx``, do ::
-
-  spack install patchelf%oneapi
-
-
-Using oneAPI Spack environment
--------------------------------
-
-In this example, we build lammps with ``icx`` using Spack environment for oneAPI packages created by Intel. The
-compilers are installed with Spack like in example above.
-
-Install the oneAPI compilers::
-
-  spack install intel-oneapi-compilers
-
-Add the compilers to your ``compilers.yaml`` so Spack can use them::
-
-  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/bin
-  spack compiler add `spack location -i intel-oneapi-compilers`/compiler/latest/bin
-
-Verify that the compilers are available::
-
-  spack compiler list
-
-Clone `spack-configs <https://github.com/spack/spack-configs>`_ repo and activate Intel oneAPI CPU environment::
-
-  git clone https://github.com/spack/spack-configs
-  spack env activate spack-configs/INTEL/CPU
-  spack concretize -f
-
-`Intel oneAPI CPU environment <https://github.com/spack/spack-configs/blob/main/INTEL/CPU/spack.yaml>`_  contains applications tested and validated by Intel, this list is constantly extended. And currently it supports:
-
-- `Devito <https://www.devitoproject.org/>`_
-- `GROMACS <https://www.gromacs.org/>`_
-- `HPCG <https://www.hpcg-benchmark.org/>`_
-- `HPL <https://netlib.org/benchmark/hpl/>`_
-- `LAMMPS <https://www.lammps.org/#gsc.tab=0>`_
-- `OpenFOAM <https://www.openfoam.com/>`_
-- `Quantum Espresso <https://www.quantum-espresso.org/>`_
-- `STREAM <https://www.cs.virginia.edu/stream/>`_
-- `WRF <https://github.com/wrf-model/WRF>`_
-
-To build lammps with oneAPI compiler from this environment just run::
-
-  spack install lammps
-
-Compiled binaries can be find using::
-
-  spack cd -i lammps
-
-You can do the same for all other applications from this environment.
-
-
-Using oneAPI MPI to Satisfy a Virtual Dependence
-------------------------------------------------------
-
-The ``hdf5`` package works with any compatible MPI implementation. To
-build ``hdf5`` with Intel oneAPI MPI do::
-
-  spack install hdf5 +mpi ^intel-oneapi-mpi
-
-Using Externally Installed oneAPI Tools
-=======================================
-
-Spack can also use oneAPI tools that are manually installed with
-`Intel Installers`_.  The procedures for configuring Spack to use
-external compilers and libraries are different.
-
-Compilers
----------
-
-To use the compilers, add some information about the installation to
-``compilers.yaml``. For most users, it is sufficient to do::
-
-  spack compiler add /opt/intel/oneapi/compiler/latest/bin
-
-Adapt the paths above if you did not install the tools in the default
-location. After adding the compilers, using them is the same
-as if you had installed the ``intel-oneapi-compilers`` package.
-Another option is to manually add the configuration to
-``compilers.yaml`` as described in :ref:`Compiler configuration
-<compiler-config>`.
-
-Before 2024, the directory structure was different::
-  
-  spack compiler add /opt/intel/oneapi/compiler/latest/linux/bin/intel64
-  spack compiler add /opt/intel/oneapi/compiler/latest/linux/bin
-
-
-Libraries
----------
-
-If you want Spack to use oneMKL that you have installed without Spack in
-the default location, then add the following to
-``~/.spack/packages.yaml``, adjusting the version as appropriate::
-
-  intel-oneapi-mkl:
-    externals:
-    - spec: intel-oneapi-mkl@2021.1.1
-      prefix: /opt/intel/oneapi/
-
-
-Using oneAPI Tools Installed by Spack
-=====================================
-
-Spack can be a convenient way to install and configure compilers and
-libraries, even if you do not intend to build a Spack package. If you
-want to build a Makefile project using Spack-installed oneAPI compilers,
-then use spack to configure your environment::
-
-  spack load intel-oneapi-compilers
-
-And then you can build with::
-
-  CXX=icpx make
-
-You can also use Spack-installed libraries. For example::
-
-  spack load intel-oneapi-mkl
-
-Will update your environment CPATH, LIBRARY_PATH, and other
-environment variables for building an application with oneMKL.
-
-More information
-================
-
-This section describes basic use of oneAPI, especially if it has
-changed compared to Parallel Studio. See :ref:`intelpackage` for more
-information on :ref:`intel-virtual-packages`,

-   This temporary stub is required such that the ``intel-parallel-studio`` package
-   can be installed for the ``intel`` compiler (which the package itself is going
-   to provide after the installation) rather than an arbitrary system compiler.
-   The paths given in ``cc``, ``cxx``, ``f77``, ``fc`` must exist, but will
-   never be used to build anything during the installation of ``intel-parallel-studio``.
+   You are right to ask: "Why on earth is that necessary?" [fn8]_.
+   The answer lies in Spack striving for strict compiler consistency.
+   Consider what happens without such a pre-declared compiler stub:
+   Say, you ask Spack to install a particular version
+   ``intel-parallel-studio@edition.V``.  Spack will apply an unrelated compiler
+   spec to concretize and install your request, resulting in
+   ``intel-parallel-studio@edition.V %X``. That compiler ``%X`` is not going to
+   be the version that this new package itself provides. Rather, it would
+   typically be ``%gcc@...`` in a default Spack installation or possibly indeed
+   ``%intel@...``, but at a version that precedes ``V``.
 
-   The reason for this stub is that ``intel-parallel-studio`` also provides the
-   ``mpi`` and ``mkl`` packages and when concretizing a spec, Spack ensures
-   strong consistency of the used compiler across all dependencies:  [fn8]_.
-   Installing a package ``foo +mkl %intel`` will make Spack look for a package
-   ``mkl %intel``, which can be provided by ``intel-parallel-studio+mkl %intel``,
-   but not by ``intel-parallel-studio+mkl %gcc``.
+   The problem comes to the fore as soon as you try to use any virtual ``mkl``
+   or ``mpi`` packages that you would expect to now be provided by
+   ``intel-parallel-studio@edition.V``.  Spack will indeed see those virtual
+   packages, but only as being tied to the compiler that the package
+   ``intel-parallel-studio@edition.V`` was concretized with *at installation*.
+   If you were to install a client package with the new compilers now available
+   to you, you would naturally run ``spack install foo +mkl %intel@V``, yet
+   Spack will either complain about ``mkl%intel@V`` being missing (because it
+   only knows about ``mkl%X``) or it will go and attempt to install *another
+   instance* of ``intel-parallel-studio@edition.V %intel@V`` so as to match the
+   compiler spec ``%intel@V`` that you gave for your client package ``foo``.
+   This will be unexpected and will quickly get annoying because each
+   reinstallation takes up time and extra disk space.
 
-   Failure to do so may result in additional installations of ``mkl``, ``intel-mpi`` or
-   even ``intel-parallel-studio`` as dependencies for other packages.
+   To escape this trap, put the compiler stub declaration shown here in place,
+   then use that pre-declared compiler spec to install the actual package, as
+   shown next.  This approach works because during installation only the
+   package's own self-sufficient installer will be used, not any compiler.

-The ``Lua`` build-system is a helper for the common case of Lua packages that provide
-a rockspec file.  This is not meant to take a rock archive, but to build
-a source archive or repository that provides a rockspec, which should cover
-most lua packages. In the case a Lua package builds by Make rather than
-luarocks, prefer MakefilePackage.
-
-^^^^^^
-Phases
-^^^^^^
-
-The ``LuaBuilder`` and `LuaPackage`` base classes come with the following phases:
-
-#. ``unpack`` - if using a rock, unpacks the rock and moves into the source directory
-#. ``preprocess`` - adjust sources or rockspec to fix build
-#. ``install`` - install the project
-
-By default, these phases run:
-
-.. code-block:: console
-
-   # If the archive is a source rock
-   $ luarocks unpack <archive>.src.rock
-   $ # preprocess is a noop by default
-   $ luarocks make <name>.rockspec
-
-
-Any of these phases can be overridden in your package as necessary.
-
-^^^^^^^^^^^^^^^
-Important files
-^^^^^^^^^^^^^^^
-
-Packages that use the Lua/LuaRocks build system can be identified by the
-presence of a ``*.rockspec`` file in their sourcetree, or can be fetched as
-a source rock archive (``.src.rock``). This file declares things like build
-instructions and dependencies, the ``.src.rock`` also contains all code.
-
-It is common for the rockspec file to list the lua version required in
-a dependency. The LuaPackage class adds appropriate dependencies on a Lua
-implementation, but it is a good idea to specify the version required with
-a ``depends_on`` statement.  The block normally will be a table definition like
-this:
-
-.. code-block:: lua
-
-   dependencies = {
-      "lua >= 5.1",
-   }
-
-The LuaPackage class supports source repositories and archives containing
-a rockspec and directly downloading source rock files.  It *does not* support
-downloading dependencies listed inside a rockspec, and thus does not support
-directly downloading a rockspec as an archive.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^
-Build system dependencies
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-All base dependencies are added by the build system, but LuaRocks is run to
-avoid downloading extra Lua dependencies during build.  If the package needs
-Lua libraries outside the standard set, they should be added as dependencies.
-
-To specify a Lua version constraint but allow all lua implementations, prefer
-to use ``depends_on("lua-lang@5.1:5.1.99")`` to express any 5.1 compatible
-version. If the package requires LuaJit rather than Lua,
-a ``depends_on("luajit")`` should be used to ensure a LuaJit distribution is
-used instead of the Lua interpreter. Alternately, if only interpreted Lua will
-work ``depends_on("lua")`` will express that.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Passing arguments to luarocks make
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If you need to pass any arguments to the ``luarocks make`` call, you can
-override the ``luarocks_args`` method like so:
-
-.. code-block:: python
-
-    def luarocks_args(self):
-        return ["flag1", "flag2"]
-
-One common use of this is to override warnings or flags for newer compilers, as in:

-.. code-block:: python

-    def luarocks_args(self):
-        return ["CFLAGS='-Wno-error=implicit-function-declaration'"]

-Apache Maven is a general-purpose build system that does not rely
-on Makefiles to build software. It is designed for building and
-managing and Java-based project.
-
-^^^^^^
-Phases
-^^^^^^
-
-The ``MavenBuilder`` and ``MavenPackage`` base classes come with the following phases:
-
-#. ``build`` - compile code and package into a JAR file
-#. ``install`` - copy to installation prefix
-
-By default, these phases run:
-
-.. code-block:: console
-
-   $ mvn package
-   $ install . <prefix>
-
-
-^^^^^^^^^^^^^^^
-Important files
-^^^^^^^^^^^^^^^
-
-Maven packages can be identified by the presence of a ``pom.xml`` file.
-This file lists dependencies and other metadata about the project.
-There may also be configuration files in the ``.mvn`` directory.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^
-Build system dependencies
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Maven requires the ``mvn`` executable to build the project. It also
-requires Java at both build- and run-time. Because of this, the base
-class automatically adds the following dependencies:
-
-.. code-block:: python
-
-   depends_on("java", type=("build", "run"))
-   depends_on("maven", type="build")
-
-
-In the ``pom.xml`` file, you may see sections like:
-
-.. code-block:: xml
-
-   <requireJavaVersion>
-      <version>[1.7,)</version>
-   </requireJavaVersion>
-   <requireMavenVersion>
-      <version>[3.5.4,)</version>
-   </requireMavenVersion>
-
-
-This specifies the versions of Java and Maven that are required to
-build the package. See
-https://docs.oracle.com/middleware/1212/core/MAVEN/maven_version.htm#MAVEN402
-for a description of this version range syntax. In this case, you
-should add:
-
-.. code-block:: python
-
-   depends_on("java@7:", type="build")
-   depends_on("maven@3.5.4:", type="build")
-
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Passing arguments to the build phase
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The default build and install phases should be sufficient to install
-most packages. However, you may want to pass additional flags to
-the build phase. For example:
-
-.. code-block:: python
-
-   def build_args(self):
-       return [
-           "-Pdist,native",
-           "-Dtar",
-           "-Dmaven.javadoc.skip=true"

-^^^^^^^
-Testing

-
-``PerlPackage`` provides a simple stand-alone test of the successfully
-installed package to confirm that installed perl module(s) can be used.
-These tests can be performed any time after the installation using
-``spack -v test run``. (For more information on the command, see 
-:ref:`cmd-spack-test-run`.)
-
-The base class automatically detects perl modules based on the presence
-of ``*.pm`` files under the package's library directory. For example,
-the files under ``perl-bignum``'s perl library are:
-
-.. code-block:: console
-
-   $ find . -name "*.pm"
-   ./bigfloat.pm
-   ./bigrat.pm
-   ./Math/BigFloat/Trace.pm
-   ./Math/BigInt/Trace.pm
-   ./Math/BigRat/Trace.pm
-   ./bigint.pm
-   ./bignum.pm
-
-
-which results in the package having the ``use_modules`` property containing:
-
-.. code-block:: python
-
-   use_modules = [
-       "bigfloat",
-       "bigrat",
-       "Math::BigFloat::Trace",
-       "Math::BigInt::Trace",

-       "bignum",
-   ]
-
-.. note::
-
-   This list can often be used to catch missing dependencies.
-
-If the list is somehow wrong, you can provide the names of the modules
-yourself by overriding ``use_modules`` like so:
-
- .. code-block:: python
-
-    use_modules = ["bigfloat", "bigrat", "bigint", "bignum"]
-
-If you only want a subset of the automatically detected modules to be
-tested, you could instead define the ``skip_modules`` property on the
-package. So, instead of overriding ``use_modules`` as shown above, you
-could define the following:
-
- .. code-block:: python
-
-    skip_modules = [
-        "Math::BigFloat::Trace",
-        "Math::BigInt::Trace",
-        "Math::BigRat::Trace",

-Caveats
-^^^^^^^
-
-In principle, ``raco`` supports a second, ``setup`` phase; however, we have not
-implemented this separately, as in normal circumstances, ``install`` also handles
-running ``setup`` automatically.
-
-Unlike Python, Racket currently on supports two installation scopes for packages, user
-or system, and keeps a registry of installed packages at each scope in its configuration files.
-This means we can't simply compose a "``RACKET_PATH``" environment variable listing all of the
-places packages are installed, and update this at will.
-
-Unfortunately this means that all currently installed packages which extend Racket via ``raco pkg install``
-are accessible whenever Racket is accessible.
-
-Additionally, because Spack does not implement uninstall hooks, uninstalling a Spack  ``rkt-`` package
-will have no effect on the ``raco`` installed packages visible to your Racket installation.
-Instead, you must manually run ``raco pkg remove`` to keep the two package managers in a mutually
-consistent state.
