@Louise-Linaro

Can you please use
mpiicx instead of mpiicc?

Hi @TobiasK

I get the same problem. The symbol is missing.

$ mv statusc2f.c statusc2f.cpp $ mpiicpx -o statusc2f statusc2f.cpp /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: /tmp/icpx-3554b074ae/statusc2f-5e7312.o: in function `main': statusc2f.cpp:(.text+0x2f): undefined reference to `MPI_Status_c2f' icpx: error: linker command failed with exit code 1 (use -v to see invocation)
