Feb 01, · I have g77 working fine in Fedora 9 (Sulphur), but recently I have got some files which can be compiled using Fortran 90 compiler. My system has Fortran 95 compiler but unfortunately it is of no help, as I cannot compile files using it. For compiling I need to use f90 command. So please, some one can suggest how I can get fortran 90 compiler. Supports FORTRAN 77, Fortran 90, Fortran 95, Fortran , and a subset of the Fortran standard; supports a subset of Technical Specification for further interoperability of Fortran with C; helps to protect investments in existing Fortran source and object code that is built with previous versions of the compilers; supports compatibility of object code or libraries that are compiled. This is the GNU Fortran 95 compiler, which compiles Fortran 95 on platforms supported by the gcc compiler. It uses the gcc backend to generate optimized code. If you specifically need the bleeding edge features of Fortran 77, there's f2c program which apparently can translate Fortran 77 into C.
