Compiling with MPI 4 about pumgen

[krenzland]

Huh, this is a bit confusing. I have the following situation on my local machine:
During PUMGen cmake configuration phase:

-- Found MPI_C: /usr/lib64/openmpi/lib/libmpi.so (found version "3.1") 
-- Found MPI_CXX: /usr/lib64/openmpi/lib/libmpi_cxx.so (found version "3.1") 
-- Found MPI: TRUE (found version "3.1")  

However:

lukas@thinkpad ~/build/PUMGen
 % mpiexec --version
mpiexec (OpenRTE) 4.1.0

I only have one version of MPI installed on my system.

Your errors indicate, that they result from a warning that's upgraded to an error by "-Werror". Are you trying to compile the core library? In this case, you have to remove the -Werror from their makefile manually. Not sure why anyone would ship with -Werror by default...

That is indeed the case, thank you
