Open Source Fortran Compilers

MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.

TDM-GCC is now hosted on Github at https://jmeubank.github.io/tdm-gcc/. The most recent stable releases from the GCC compiler project, for 32-bit and 64-bit Windows, cleverly disguised with a real installer & updater.

Projects joined MinGW-W64, and the new builds will be available on the MinGW-W64 site: https://sourceforge.net/projects/mingw-w64

gputils is a collection of tools for Microchip PIC microcontrollers. Its goal is to be fully compatible with Microchip's tools, MPASM, MPLINK, and MPLIB.

CodeBlocks With A full development environment. Took a while but CodeBlocks is now upto speed and in sync with the current release version. New version of CodeBlocks supports XML based configuration, so users can do specialized compiler support if needed. Changed away from the old Msys in favor of Msys2 which has better support for a lot of things like miktex. Old package is still there if you still need it but wont be developed on anymore. Loads of modifications compared to the Msys2 package from Alex, you can still update Msys2 packages from his server though. MinGW64 packages have to many changes compared to Alex version so those will not upgrade but im working on creating my own package server. Current Msys2/MinGW64 gcc is now 6.2.0-4 and binutils 2.27. New packages will be uploaded shortly. Stay tuned for more changes.

The Open64 Compiler and Tools site is dedicated to the continued development of the former SGI Pro64(TM) compiler for the IA64, x86, CUDA and MIPS architecture.

This is a pseudo Fortran77 compiler for Atmel/Microchip AVR microcontroller, written in Fortran using gfortran compiler. The compiler use avr-gcc as dependency. As of version 1.0.3-1 (8 July 2026), the compiler introduces near-comprehensive native compatibility with Fortran 77 syntax.

Bundled gcc compiler and tools for Perl on MS Windows (32 and 64 bit). Provides C, C++, Fortran

A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.

Loglan'82 is a programming language conceived for object and distributed programming. It has many features that make Loglan'82 a tool surpassing other programming languages: * It enjoys a unique safe and efficient system of managing objects, see [[Safe dealocation]], * It offers modules of classes (__class__), moreover it allows to declare modules of cooperating objects i.e. **coroutines** and modules of threads ('''process'''). One can create not only objects of classes, but also objects of coroutines with their ''fibres'' and objects of processes, aka agents with their *threads*. * Virtual machines of Loglan may connect (through internet) in a virtual, multiprocesorr computer.This allows to distribute a computation of a program between processors in a controlled way. * Objects of processes (agents) can be alocated on different nodes of a network of virtual machines or on the same machine.

GNUDE is a complete suite of GNU C, C++, Fortran, and Java Cross Compilers, and the GDB CPU Simulator and Debugger for embedded microprocessor applications development. Targets development for ARM7, ARM9, and XScale applications.

cfortran.h is an easy-to-use powerful bridge between C and FORTRAN. It provides a transparent, machine independent interface between C and FORTRAN routines and global data.

Formula Compiler Source for writing your own compiler. Arithmetic expressions & functions; IF-THEN; AND OR ..; EQ GT ..; user functions like threshold, flipflop; others are easy to be implemented

The purpose of this project was to prepare gfortran for integration into gcc. Since this integration was completed in the summer of 2003, this project is now finished. You can find information about gfortran on http://gcc.gnu.org/wiki/GFortran/

Chasm-interop is a set of tools that parses C++ and Fortran 90 source files and automatically generates bridging code to provide for seamless language interoperability.

This project aims at providing a parser for fortran source code. Output is in XML format. The parser is based on the g95 parser. Additionnal tools in Perl are provided: Fortran source browser; pseudo-compiler environment.
