Dear Justin, We have validated a NONMEM cluster running on Red Hat, using g77 (gcc version 3.4.6 20060404). We had no problem with this compiler. Best regards Maud

We call it g77 for the purpose of interacting with existing elements of the installation, namely PsN. Our rather demanding tests are running quite smoothly but our system is not yet in the production phase. Any other users out there who are happy with gfortran as substitute for g77 as compiler?

One way to address this would be to compile the trapfpe.c routine that's floating around the Internet into the NONMEM library, I think, but I can't help wondering whether there is a more elegant fix (apart from writing less buggy NONMEM code). Has anyone had any recent experience with dealing with this? If we were to dump g77 altogether, what other compilers are known to work adequately with NONMEM on Linux?
