Hi napi! The step by step instructions are... the only and unique step I put in post #5 of this thread:
yum install gcc-gfortran
or you can use the more friendly Add/Remove software from the Applications menu of the Desktop. Obviuosly this requires you have root privileges in order to install new packages on this system and a valid internet connection (but you can install them from the Fedora installation DVD as well).
I can add that to build an application from source you probably need some other tools, like make
. For your convenience you can install them all using the following yum command:
yum groupinstall "Development Tools"
Finally to install the GAMESS software, follow step by step instructions from the developer, having in mind your F77 executable is /usr/bin/gfortran.
