If a variant or dependency constraint from a matrix is -invalid, Spack will reject the constraint and try again without -it. For example, the following two Environment manifests will produce -the same specs: - -.. code-block:: yaml - - spack: - specs: - - matrix: - - [zlib, libelf, hdf5+mpi] - - [^mvapich2@2.2, ^openmpi@3.1.0] - - spack: - specs: - - zlib - - libelf - - hdf5+mpi ^mvapich2@2.2 - - hdf5+mpi ^openmpi@3.1.0 - -This allows one to create toolchains out of combinations of -constraints and apply them somewhat indiscriminately to packages, -without regard for the applicability of the constraint. - ^^^^^^^^^^^^^^^^^^^^ Spec List References ^^^^^^^^^^^^^^^^^^^^ |
