history
Project history and usage
cc65 is a complete cross-development toolchain for 65(C)02 systems, including a C compiler, macro assembler, linker, archiver, simulator, and supporting tools.
Project history
The official README traces cc65 to Ron Cain's Small C, enhanced by James E. Hendrix, then to John R. Dunning's Atari-hosted compiler/runtime implementation. Ullrich von Bassewitz moved the code to modern systems, rewrote most of the compiler, and rewrote the runtime library.
Adoption history
cc65 became a long-lived retrocomputing toolchain because it supports many 6502-family targets, including Apple II, Atari 8-bit systems, Commodore machines, NES, Oric, BBC, PC Engine, KIM-1, Commander X16, and others. The supplied package facts show it is packaged across Homebrew, Debian, Fedora, MacPorts, Nix, Scoop, Ubuntu, and Alpine.
How it is used
Developers use cc65 to build C and assembly programs for old 6502-family machines and custom hardware. The official documentation covers each tool and shows that ld65 linker configuration files define output layout, memory areas, and segment placement.
Why package nerds care
cc65 is a classic package-manager fixture: a portable cross-compiler suite that lets modern hosts build software for many constrained historic targets. Its many small executables also make it a good test case for toolchain packaging, documentation paths, and target-library layout.
