Subject: [bug#32732] [PATCH] gnu: hdf5-parallel-openmpi: Really enable parallel build.
Date: Thu, 13 Sep 2018 21:03:25 +0100

This fix ensures that the H5_HAVE_PARALLEL identifier is correctly set
in the file H5pubconf.h.

* gnu/packages/maths.scm (hdf5-parallel-openmpi)[arguments]: Add
the "--enable-parallel" flag to the list of configure flags.  Remove
the incompatible "--enable-cxx" flag.  Add 'mpi-setup' phase.  Replace
the 'split' phase, omitting the references to the h5fc script which is
not present.
