I had the same exact problem with my PGI compilers, (no problems
reported yet with my intel compilers). I have a fix for you.
You would think that the compiler would automatically look in
/usr/lib64, since that's one of the system's default lib directories,
but the PGI compilers don't for some reason.
A quick fix is to do
A more permanent fix is to edit
In my case, I also had to add the OpenMPI lib directory for the PGI
compilers, too. You may or may not need to add them, too:
You may want to test all your compilers and makea similar change to all
your *wrapper-data.txt files
Not sure if this is a problem with the compilers not picking up the
system's lib dirs, or an OpenMPI configuration/build problem.
