A cross development system for processors in the old MOSTEK 65xx family and compatible devices, it includes a macro assembler, a C compiler, linker, librarian and several other utilities.
Ullrich von Bassewitz had been developing the package for most of its lifetime but stopped development in 2013, however his last release was a quite extensive bug fix release, meaning that the tool as it stands is quite capable and relatively bug free. His version supported cross development from a number of platforms and a self hosted toolchains on all systems that had full C and runtime library support (see below).
Oliver Schmidt took over the maintenance of the cc65 project, however he only supports cross compilation from a MS Windows environment, his latest release features no major changes to codebase so it could probably be ported back to OS/2 with only minimal changes.
Full C and runtime library support for:
- Commodore machines:
- C16/C116 and Plus/4
- CBM 510 (aka P500)
- 600/700 family
- Newer PET machines (not 2001).
- Apple II and successors.
- Atari 8 bit machines.
- GEOS for the C64 and C128.
- Nintendo Entertainment System (NES).
- Supervision console.
- Oric Atmos.
- The Lynx Console.
- Last OS/2 version: 2.13.3-1 (2012-2-8)
- Current MS Windows version: Snapshot (2015-01-20)
- Open source software, the compiler,linker and librarian are released under a freeware license that was a variant of the GPL v1 License and has somewhat unique terms, the libraries and the rest of the tools are released under the Zlib License.
