Known Issues

============

|
|
This is a list of known bugs in Spack. It provides ways of getting around these
|
|
problems if you encounter them.
|
|
|
|
-----------------------------------------------------------------
|
|
Default variants are not taken into account during concretization
|
|
-----------------------------------------------------------------
|
|
|
|
**Status:** Expected to be fixed in the next release
|
|
|
|
Current concretization algorithm does not take into account default values
|
|
of variants when adding extra constraints to the spec via CLI. For example
|
|
you may encounter the following error when trying to specify which MPI provider
|
|
to use:
|
|
|
|
.. code-block:: console
|
|
|
|
$ spack install hdf5 ^openmpi
|
|
==> Error: hdf5 does not depend on openmpi
|
|
|
|
although the hdf5 package contains:
|
|
|
|
.. code-block:: python
|
|
|
|
variant('mpi', default=True, description='Enable MPI support')
|
|
depends_on('mpi', when='+mpi')
|
|
|
|
A workaround is to explicitly activate the variant related to the dependency:
|
|
|
|
.. code-block:: console
|
|
|
|
$ spack install hdf5+mpi ^openmpi
|
|
|
|
See https://github.com/LLNL/spack/issues/397 for further details.

|
|
``spack extensions`` doesn't work
|
|
---------------------------------
|
|
|
|
**Status:** Up for grabs if you want to try to fix it
|
|
|
|
Spack provides an ``extensions`` command that lists all available extensions
|
|
of a package, the ones that are installed, and the ones that are already
|
|
activated. This is very useful in conjunction with ``spack activate``.
|
|
Unfortunately, this command no longer works:
|
|
|
|
.. code-block:: console
|
|
|
|
$ spack extensions python
|
|
==> python@2.7.13%clang@8.0.0-apple~tk~ucs4 arch=darwin-sierra-x86_64 -ckrr4mg has no extensions.

|
|
``spack setup`` doesn't work
|
|
----------------------------
|
|
|
|
**Status:** Work in progress
|
|
|
|
Spack provides a ``setup`` command that is useful for the development of
|
|
software outside of Spack. Unfortunately, this command no longer works.
|
|
See https://github.com/LLNL/spack/issues/2597 and
|
|
https://github.com/LLNL/spack/issues/2662 for details. This is expected
|
|
to be fixed by https://github.com/LLNL/spack/pull/2664.
