Open Source C Compilers for BSD

CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

Implementation of ANSI Standard MUMPS 1995 and ISO/IEC 11756 for FreeBSD, OSX and linux. Also on the Raspberry Pi (ARM) under debian and Windows under cygwin. This is the post-relational database.

Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c

ATasm is a 6502 command-line cross-assembler that is compatible with the original Mac/65 macro assembler released by OSS software. The aim of ATasm is to provide Atari home-brew coders with a comfortable and powerful toolset.

coNCePTuaL is a toolset for rapidly generating portable, readable, and reproducible network-performance tests. coNCePTuaL can perform the equivalent of many pages of C code with just a few mouse clicks or lines of code in a domain-specific language.

Write programs as graphical dataflow charts instead of text. Compile them to any programming language you want. Besides this project includes the most efficient tree-based sorting algorithm that is possible. Originally developed on a CTOS Color NGEN, at first in Pascal, later ported to C, finally - 20 years later - ported to Linux. Currently it's still not really system independent. But it's intended that further releases will cure this.

ZASM is a 2 pass assembler for Zilog's 8-bit CPU Z80. Supported platforms: Unix-style OS, e.g. MacOS X, Linux, BSD. Special support for ZX Spectrum emulator file formats. Binary or intel hex file output.

FastSim consists of: - 'Facile' a highly flexible and expressive processor-architecture specification-language. - A compiler for the specifications which produces high-performance, fast-forwarding simulators.

This project aims to create an ARM processor emulator for Linux/x86, utilising dynamic binary translation techniques for maximum speed.

Compiler for message-passing network protocols, currently based on UDP. APC is written in Python and produces C code. It includes a C run-time library.

A collection of tools to tokenize PBASIC source code and send it to a BASIC Stamp microcontroller.

Netflow analyzing tools : JXColl - collector for Netflow (or XML specified) data Analyzer - front-end application for providing an user interface and output (graphs, statistics, etc.)

CORBA for PHP is a PHP Extension to use CORBA objects in PHP5(Zend Engine 2). It uses MICO as its ORB and will also provide an Idl-to-PHP language mapping specification and compiler. For a PHP4 CORBA support look at the great Universe-phpext.

RPC (Remote Procedure Call) system with C language support, own network protocol, automatic parallelization, SSL support and other features.

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

The goal of the Embedded Debian Project is to make Debian GNU/Linux a natural choice for embedded Linux.

The goal of EnerWare is to design and create language primitives and/or extensions that enable the support and provision for energy awareness in resource-constrained systems such as embedded sensors and large-scale servers.

This project aims for a completely free alternative to the GNU software. Since RMS/GNU makes restrictions infringing on use of their software by all, we're removing that restriction completely, by placing every line into the Public Domain

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.

The MDK provides a simulator of D. Knuth's MIX computer, and a development environment to write, run and debug MIXAL programs on it.

LIME (Less-is-More) is parallel/concurrent programming environment based on C. Internally, it uses XML technology to describe tasks and their dependencies. Externally, it offers the ANSI C99 programming as well as a set of visually-oriented interfaces.

MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler

Lem is a object-oriented extension language with a C-like syntax. A Lem "source" program is compiled interactively and then executed. This project aims also to develop a shell (lemsh) based on the Lem programming language.

The MyNOS project aims at developing a new and different operating system, based on high-level languages. MyNOS will be based on the OCaml bytecode interpreter. We'd like to explore microkernel architecture and new language definition too.
