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.[1] 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 and Watara Supervision game console.
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.
Supported API
static
- conio (text-based console I/O non-scrolling)
- dio (block-oriented disk I/O bypassing the file system)
dynamic
- em (expanded memory, used for all kinds of memory beyond the 6502's 64K barrier, similar EMS)
- joystick (relative input devices)
- mouse (absolute input devices)
- serial (communication)
- tgi (2D graphics primitives inspired by BGI)

Note: For static libraries, "Yes" means the feature is available. For dynamic libraries, the columns list the number of available drivers.
