Hi Seth,
>From my experience with Sander and 64-bit opterons, the "-m32" flag does
not help as it forces your c compiler to compile for a 32-bit
environment, while ifort is most likely optimizing for a 64-bit memory
space. Below is my copy of the C compiler section from config.h which
has worked fine with mixed gcc/ifort and gcc/pgf90 for serial and
parallel versions.
By the way, where exactly does the error occur? It may be helpful to
send a brief selection of the compilation errors to the group to help
track down where the problem comes from.
Good luck,
