Is GCC a Fortran compiler?
gfortran — the GNU Fortran compiler, part of GCC. Gfortran is the name of the GNU Fortran project, developing a free Fortran 95/2003/2008/2018 compiler for GCC, the GNU Compiler Collection.
Is f77 a compiler?
Before you can execute the program, you have translate the program into machine readable form. This is done by a special program called a compiler. The Fortran 77 compilers are usually called f77.
What is a compiler in Fortran?

How does the GNU Fortran compiler work?
If I remember well GNU doesn’t have a FORTRAN compiler but a FORTRAN preprocessor (or whatever the name for that is). It just translates your code to C and the compiles it with the C compiler. Of course performance becomes crap in the process.
What is the best compiler for FORTRAN 77?
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.
What is the difference between G77 and GFortran?
g77 ang gfortran are different compilers. g77 is replaced by gfortran in the GNU compiler collection (GCC), it is not renamed gfortran. gfortran is a modern Fortran compiler based on the g95 compiler. g77 is abandonware. They do not share codebase.
What versions of Fortran does GFortran support?
The GFortran compiler is fully compliant with the Fortran 95 Standard and includes legacy F77 support. In addition, a significant number of Fortran 2003 and Fortran 2008 features are implemented.
