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 original cc65 compiler was freely redistributable in source form, but does not qualify as Open Source Software according to the Open Source Definition due to the fact that distribution of the software for monetary profit is not allowed. ... The Open Source Definition is used by the Open Source Initiative to determine whether or not a software license can be considered open source. ...

The toolkit has largely been expanded by Ullrich von Bassewitz and other contributors. The actual cc65 compiler remains under the "freeware" license until it is completely rewritten, but the efforts have already produced a complete set of binary tools (assembler, linker, etc) and runtime library 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. zlib is an open-source, cross-platform data compression library. ...

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. The library supports many of the Commodore platforms (C64, C128, C16/116/Plus/4 P500 and 600/700 family), Apple II family, Atari, Oric Atmos, Nintendo Entertainment System and Supervision game console.
