[mpich-discuss] mpich2 compilation with intel only

[David Riethmiller]

Hmmm, actually now that I try it, I am not able to compile a "hello  
world" program with -no-gcc and #include <stdarg.h> together.

If I remove -no-gcc from my configure shell script, the configure is  
successful, which leads me to my next question:

Is this still considered a true Intel build, even if I've used gcc to  
build it? From here on will the Intel compilers will run my mpi calls,  
or will the GNU compiler set continue to be used?

Thanks,
Dave
