[gmx-users] SGI-O2 IRIX 6.5 Compile trouble

[Erik Lindahl]

Hi Patrick,

If you want to use the GNU compilers, just set them in the environment variables
before running configure:

CC=gcc


You could also add F77=g77, but the GNU fortran compiler isn't very good, so you
might get better performance by sticking to the C compiler and explicitly adding
--disable-fortran to avoid looking for f77.

Once the compiler script knows which compiler it should use it should detect
optimization flags, etc, automatically!

Cheers,

Erik
