Subject: [OMPI users] Open-MPI 1.6 searches for default hostfile in the wrong directory
From: Götz Waschk (goetz.waschk_at_[hidden])

Dear Open-MPI developers,

I have built my own package of openmpi 1.6 based on the RHEL6 package
on my SL6 test machine. My tests fail like this:

Open RTE was unable to open the hostfile:
    /usr/lib64/openmpi-intel/etc/openmpi-default-hostfile
Check to make sure the path and filename are correct.

This is because I have configured openmpi with ./configure
--prefix=/usr/lib64/openmpi-intel/
--sysconfdir=/etc/openmpi-x86_64-intel/.

The default hostfile was placed by 'make install' to
/etc/openmpi-x86_64-intel/openmpi-default-hostfile, but
orte/runtime/orte_mca_params.c wants a file in etc under the
configured prefix.

Regards, Götz Waschk
