[Trilinos-Users] [EXTERNAL] Trilinos Compilation Error on Linux

[John T. Foster]

Sai,

mpicc and mpicxx are just wrappers on the underlying compilers which are
most likely some version of gcc. You can see the full compiler and linker
command with mpicc -show. If the underlying compiler is in fact gcc, you
can see the version with gcc -v.
