cc65 is a cross development package for 6502 and 65C02 targets, including a macro assembler, a C cross compiler, linker, librarian and several other tools.
OverviewEdit
cc65 is based on a native C compiler that was originally adapted for the Atari 8-bit computers by John R. Dunning in 1989, which originated as a Small-C descendant. It 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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The compiler itself comes close to ANSI C compatibility, while C library features depend on the target platform's hardware. stdio is supported on many platforms, as is Borland-style Template:Mono screen handling. GEOS is also supported on the Commodore 64 and the Apple II. The library supports many of the Commodore platforms (C64, C128, C16/116/Plus/4, P500 and 600/700 family), Apple II, Atari 8-bit computers, Oric Atmos, Nintendo Entertainment System,<ref>Template:Cite book</ref><ref>Template:Cite book</ref> Watara Supervision game console, Synertek Systems SYM-1 and Ohio Scientific Challenger 1P.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Officially supported host systems include Linux, Microsoft Windows, MS-DOS and OS/2, but the source code itself has been reportedTemplate:By whom to work almost unmodified on many platforms beside these.
The ca65 macro assembler supports 6502, 65C02, and 65C816 processors, and can be used standalone without the C compiler.<ref>ca65 Users Guide</ref>
Supported APIEdit
staticEdit

- joystick (relative input devices)
- mouse (absolute input devices)
- serial (communication)
- tgi (2D graphics primitives inspired by BGI)
