[gmx-users] SGI installation problem: forcing the compilation with gcc

[Erik Lindahl]

Hi,

You can always set the environment variable CC to the compiler you  
want to use before running configure.


However, the error you're getting is really easy to fix - it just  
happens because we changed a header file, and
forgot to do

#include "shift_util.h"

in the header of ghat.c. Add that, and it should hopefully compile  
fine with the IRIX compilers too.

Cheers,

Erik
