Hi Jim,

"-g -O2" are reasonable options. You can select them in two ways:

1. Set the environment variable CFLAGS to "-g -O2" before running the 
configure script. If you have already built Gromacs you should issue a 
"make distclean" first (before rerunning configure).

or

2. Run "make clean" if you already built gromacs. Then issue the 
command:  make CFLAGS="-g -O2".


Cheers,

Erik
