Open Source Linux Compilers

GnuCOBOL (formerly OpenCOBOL) is a free, modern COBOL compiler. GnuCOBOL implements a substantial part of the COBOL 85, X/Open COBOL and newer ISO COBOL standards (2002, 2014, 2023), as well as many extensions included in other COBOL compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others). GnuCOBOL translates COBOL into C and internally compiles the translated code using a native C compiler. Build COBOL programs on various platforms, including GNU/Linux, Unix, Mac OS X, and Microsoft Windows. GnuCOBOL has also been built on HP/UX, z/OS, SPARC, RS6000, AS/400, along with other combinations of machines and operating systems. Copyright 2001-2024 Free Software Foundation, Inc.

MCPP is a portable C/C++ preprocessor, supporting GCC, Visual C++, etc. Its source is highly configurable and can generate executables of various specs. It accompanies a validation suite to check preprocessor's conformance and quality exhaustively.

RelaxNGCC is a tool for generating Java source code from a given RELAX NG grammar. By embedding code fragments in the grammar like yacc or JavaCC, you can take appropriate actions while parsing valid XML documents against the grammar.

Broccoli is a dynamically-typed, multi-paradigm programming language.
