A Weird Problem about libmpigi

ZQiang — Sun, 04 Jul 2021 09:12:56 GMT

I'm compling a project based on PETSc and SLEPc. When I use command

mpiicc -mkl=parallel -o $@ $< -Wl,-rpath,${MKLROOT}/lib/intel64 -L${MKLROOT}/lib/intel64 (and a lot of other libs) -lmpi -lmpigi

I got a error msg

ld: cannot find -lmpigi

And then I found a similar question on board, it was said that libmpigi no longer existed, and it was included in libmpi.a. However, if I remove option -lmpigi, another problem came to me

ld: warning: libfabric.so.1, needed by /home/forzzig/intel/oneapi/mpi/latest/lib/release_mt/libmpi.so, not found (try using -rpath or -rpath-link)

How should I fix this issue?

Hi,

Thanks for reaching out to us.

Could you please provide us the version of Intel MPI you have been using?

Could you also provide the sample reproducer code to investigate more on your issue?

Thanks & Regards

Shivani

I've solved this problem by adding ${MPIROOT}/libfabric/lib to the lib path.

And PCHYPRESetType is another problem caused by the package I used, not about intel mpi.

Thanks all the same!
