Subject: [bug#32732] [PATCH 2/2] gnu: hdf5-parallel-openmpi: Really enable parallel build.
Date: Thu, 20 Sep 2018 18:59:57 +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.
