Cc65

cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools.

It is based on a C compiler that was originally adapted for the Atari 8-bit computers by John R. Dunning. The original C compiler is a Small C descendant but has several extensions, and some of the limits of the original Small C compiler are gone.

The toolkit has largely been expanded by Ullrich von Bassewitz and other contributors. The actual cc65 compiler, a complete set of binary tools (assembler, linker, etc.) and runtime library are under a license identical to zlib's. The ca65 cross-assembler is one of the most powerful 6502 cross-assemblers available under an open-source license.

The compiler itself is almost completely ANSI C compatible, though not completely. The C library is quite extensive, and allows extensive usage of the target platform's hardware. stdio is supported on many platforms, as is Borland-style conio.h screen handling. GEOS is also supported on the Commodore 64 and even the Apple II. The library supports many of the Commodore platforms (C64, C128, C16/116/Plus/4, P500 and 600/700 family), Apple II family, Atari 8-bit family, Oric Atmos, Nintendo Entertainment System, Watara Supervision game console and Ohio Scientific Challenger 1P.

The officially supported host systems include Linux, Microsoft Windows, DOS and OS/2, but the source code itself is quite portable and has been reported to work almost unmodified on many platforms beside these.
