Details of the problem

Discrepancy between compiler wrapper oshcc and corresponding pkg-config files "oshmem-c.pc" and "oshmem.pc". Cflags specifies -I/usr/lib64/openmpi/lib, which is not present in oshcc wrapper flags. "/usr/lib64/openmpi/lib" itself does not contain header files, nor is it present in "oshmem-cxx.pc".

Formatted output:

$ oshcc --showme
gcc 
-I/usr/include/openmpi-x86_64 
-L/usr/lib64/openmpi/lib 
-Wl,-rpath -Wl,/usr/lib64/openmpi/lib 
-Wl,--enable-new-dtags 
-loshmem 
-lmpi

$ pkg-config --libs --cflags oshmem-c
-I/usr/include/openmpi-x86_64 
-I/usr/lib64/openmpi/lib               # Discrepancy
-L/usr/lib64/openmpi/lib 
-Wl,-rpath -Wl,/usr/lib64/openmpi/lib
