Bug 354993 – sci-libs/arpack-96-r2 does not work with sys-cluster/openmpi-1.4.2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Yang Zhang 2011-02-15 10:19:41 UTC]

sci-libs/arpack-96-r2 compiles correctly with openmpi, but when you use it
in an application, it will result in the following error:

MPI_ERR_OP: invalid reduce operation

A similar error can be found at http://linuxtoolkit.blogspot.com/2010/08/mpierrorsarefatal-for-arpack-running.html

The webpage above shows that this is an compatibility issue of old arpack w.r.t new MPI implementation. And this issue can be solved by forcing the arpack building system to use system mpif.h instead of the bundled one.

Ebuild with the issue solved

Solve the compatibility issue by copying the system mpif.h to workdir

Please forgive my laziness. I chose to copy directly the system mpif*.h to PARPACK/SRC/MPI for a straight-forward solution. A cleaner solution can be to remove PARPACK/SRC/MPI/mpif.h and use mpif77 af MPIF77/F77.
