Hello,

So oddly enough, i fail to compile libso foam because it cannot find -lmpi.

Im using OpenMPI 4.0.3 that I compiled with gcc-7.5 (compilation of both were a success). The OS is Fedora 35 aarch64

Error message as followed:

Note: ignore spurious warnings about missing mpicxx.h headers
+ wmake libso foam

The issue is, LD LIBRARY PATH is pointed to my openmpi and everything on the mpi side works, howver compiling with -lmpi fails.

Anyone know have any ideas? The compilation of the other libraries go as normal so far, but I cant understand why its only this library that fails to find -lmpi
