[gmx-users] problems building gromacs 3.3 with mpi on MacOS X

[Erik Lindahl]

Hi,

Actually, the best option is to submit a bugzilla feature request,  
together with a description of how to identify the compiler (and/or  
version) - then we'll add it into the configure script for  
autodetection!

For instance, the intel compilers are identified by using

$CC -V 2>&1 | grep 'Intel'
$F77 -V 2>&1 | grep 'Intel'

and xlc on OS X:

$CC 2>&1 | grep 'IBM'

Cheers,

Erik
