Getting Started
|
|
====================
|
|
|
|
Download
|
|
--------------------
|
|
|
|
Getting spack is easy. You can clone it from the `github repository
|
|
<https://github.com/llnl/spack>`_ using this command:
|
|
|
|
.. code-block:: sh
|
|
|
|
$ git clone https://github.com/llnl/spack.git
|
|
|
|
This will create a directory called ``spack``. We'll assume that the
|
|
full path to this directory is in the ``SPACK_ROOT`` environment
|
|
variable. Add ``$SPACK_ROOT/bin`` to your path and you're ready to
|
|
go:
|
|
|
|
.. code-block:: sh
|
|
|
|
$ export PATH=$SPACK_ROOT/bin:$PATH
|
|
$ spack install libelf
|
|
|
|
For a richer experience, use Spack's `shell support
|
|
<http://software.llnl.gov/spack/basic_usage.html#environment-modules>`_:
|
|
|
|
.. code-block:: sh
|
|
|
|
# For bash users
|
|
$ . $SPACK_ROOT/share/spack/setup-env.sh
|
|
|
|
# For tcsh or csh users (note you must set SPACK_ROOT)
|
|
$ setenv SPACK_ROOT /path/to/spack
|
|
$ source $SPACK_ROOT/share/spack/setup-env.csh
|
|
|
|
This automatically adds Spack to your ``PATH``.
|
|
|
|
Installation
|
|
--------------------
|
|
|
|
You don't need to install Spack; it's ready to run as soon as you
|
|
clone it from git.
|
|
|
|
You may want to run it out of a prefix other than the git repository
|
|
you cloned. The ``spack bootstrap`` command provides this
|
|
functionality. To install spack in a new directory, simply type:
|
|
|
|
.. code-block:: sh
|
|
|
|
$ spack bootstrap /my/favorite/prefix
|
|
|
|
This will install a new spack script in ``/my/favorite/prefix/bin``,
|
|
which you can use just like you would the regular spack script. Each
|
|
copy of spack installs packages into its own ``$PREFIX/opt``
|
|
directory.
