Fortran (f77) for linux? need compiler for SLES10 preferably free
what Fortran compilers are available for linux?
I am running Suse Linux Enterprise Server 10 sp1 on an intel Itanium2 system (ia-64). That gives gfortran as a fortran compiler but it will not compile fortran code that will compile in f77. Is there a way to get f77/f90/f95 for free? If I have to pay for it, who's good? |

If you have an intel cpu, you can try the Intel Fortran Compiler for Linux (ifort). The non commercial license is free: read carefully the requirements to obtain this kind of license and see if you match them. Basically (quoting from the Intel site):

i've looked at the gcc fortran link and maybe i'm dumb but how or where do I download it from?
That page has nothing useful :confused: gnu says they dropped g77 under version 4 of the gcc and gfortran is fortran95. I am looking for the old f77 compiler, I find links here and there but never anything that lets me download the compiler so I can build it. If anyone can tell me how to get it, I would be very grateful. I also have the intel compilers, and what a pita it is with licensing. But for gnu stuff I sometimes want to build, it wants f77 not ifort. |
SuSE should have the fortran compiler in the repositories. Just use YaST and search for it. You should always check your distribution's repositories before going anywhere else - it's much easier to manage software which your package manager knows about.

Code:
ln -s /opt/intel/fc/10.0.026/bin/ifort /usr/bin/f77 Following the suggestion by matthewg42, you can try to search "fortran" in Yast package management. You will find something like gcc42-fortran. Maybe this is what you're looking for. |
Surely fortran95 is backward compatible with fortran 77?
