GAMESS(US) ifort choice

[Dmitry_G_]

Hello. I'm attempting to compile GAMESS(US) from sources using ifort compiler, but even with the environmental variables set up I get this issue:

Help me to learn and fix the problem, please.

If ifort is installed on your machine, you will need e.g. "source /opt/intel/compilers/bin/compilervars.sh intel64" (depending on where it is installed and whether intel64 or ia32 support was chosen).  Then the which command and application setup should work.

Intel Fortran (and C, MKL, etc.) is usually installed under /opt/intel or another location chosen at installation time. Within that folder, there is a shell script (ifortvars.sh, ifortvars.csh) that you have to source before the Intel Fortran compiler can be used. Unlike Gfortran/GCC, the Intel Fortran driver is usually not installed in the /usr/bin directory, which is why you have to source the start-up script.

For details, please see the Parallel Studio release notes for your OS and compiler version.

The thing is that I've done that.
