Linking with OpenMPI fails #9422

Describe the bug Compiling a program with meson and OpenMPI 4.0.5 fails with the following error (I added linebreaks for better visibility):

The output of mpic++ --showme is (again with added linebreaks):

g++
-I/opt/sw/arch/easybuild/2020b/software/OpenMPI/4.0.5-GCC-10.2.0/include

-Wl,--enable-new-dtags

-lmpi

So the problem seems that the second and third -Wl,-rpath is stripped. Adding them manually to build.ninja solves the problem.

I have a pretty good idea what's happening here.

dcbaker commented 3 years ago

My initial idea didn't pan out, can you provide the full configure output, or at least the MPI output, I want to know whether it's using pkg-config or mpic++

Here is the corresponding meson log-file of the mentioned bug:
