Is Fortran GNU Free?
GNU Fortran Compiler (gfortran) is a mature free and open source compiler, part of the GNU Compiler Collection. OpenCoarrays is a library and compiler wrapper around gfortran which enables the parallel programming features of Fortran 2018 with gfortran.
Is GFortran same as GCC?
GNU Fortran or GFortran is the GNU Fortran compiler, which is part of the GNU Compiler Collection (GCC).
Is GFortran included in GCC?
GFortran documentation is included with the GCC documentation, which is available from the GCC website. There is documentation for released compilers, and also documentation for the latest snapshot from the development tree.

What is the latest version of Fortran?
Fortran 2018
Fortran is still in active development. The latest revision of the language is Fortran 2018, and the next one, with the working title Fortran 202x, is planned for release in the next few years. Further, open source projects like the Standard Library and the Fortran Package Manager are in active development.
Does GCC compile Fortran?
GCC can compile programs written in any of these languages. The Ada, Fortran, Java and treelang compilers are described in separate manuals. “GCC” is a common shorthand term for the GNU Compiler Collection.
Is Fortran used today?
Fortran is rarely used today in industry — one ranking ranks it behind 29 other languages. However, Fortran is still a dominant language for the large scale simulation of physical systems, ie. for things like the astrophysical modeling of stars and galaxies, hydrodynamics codes (cf.
What is the GNU Fortran project?
The purpose of the GNU Fortran (GFortran) project is to develop the Fortran compiler front end and run-time libraries for GCC, the GNU Compiler Collection. GFortran development is part of the GNU Project.
How do I enable support for record structures in GNU Fortran?
Support for record structures in GNU Fortran can be enabled with the -fdec-structure compile flag. If you have a choice, you should instead use Fortran 90’s “derived types”, which have a different syntax. In many cases, record structures can easily be converted to derived types. To convert, replace STRUCTURE /structure-name/ by TYPE type-name.
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.
How many integers are there in Fortran 90?
Fortran 90 has no concept of unsigned integers, nor 1 byte or 2 byte integers. It has a single, signed integer type, typically of 4 or 8 (Fortran 2003 adds new types for C interoperability.)
