[mvapich-discuss] osu-microbenchmarks-3.6 install issues

[Gerald Trout]

Thanks for the suggestion. Subsequently ran into few other errors about missing paths. 

Eventually downloading openmpi source and reinstalling it (as against previous yum install/reinstall) helped resolve the path issues and complete the installation.

Thanks for the report.  The rest of my reply is below the relevant
error.

libmpi.so.0 is a library that OpenMPI needs to load at runtime.  This
library is not installed in one of your system paths and it appears that
the OpenMPI mpicc is not embedding an rpath into its created
executables.

You have a couple different options here.

1. Set LDFLAGS to include an rpath to the path of the OpenMPI lib
   directory.

2. Set LD_LIBRARY_PATH to include the path of the OpenMPI lib directory.

3. Setup /etc/ld.so.conf or /etc/ld.so.conf.d to look at the OpenMPI lib
   directory in addition to the other system paths.

I think the first option is best but the second option might be easiest
for you.
