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. ### Related projects - Small C, ca65, ld65, cl65, sim65, and target ecosystems for Apple II, Atari, Commodore, NES, and other 65(C)02 machines. ### Sources - - - - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
