Hi Caroline,
You can try
make FC_FLAGS_OPT=-O2 compile=opt
when building CG.

Can anyone advise how to change the gfortran flag –O3 to use –O2. I
can’t seem to locate where this option is being set.
We are running into segmentation faults using gfortran v4.4.6 while
trying to build CG v24. On an individual .f file compilation we are
getting better results compiling with –O2.
Any suggestions would be most appreciated, thanks!
Kind regards,
Caroline
