プロジェクトの歴史

GCC began as the GNU C Compiler. The GCC project history records the first beta release on March 22, 1987, by Richard Stallman, originally for the GNU operating system and initially centered on C.

During the 1990s, GCC grew beyond C into a multi-language compiler suite. The official GCC 2.95 page notes that the name changed from GNU C Compiler to GNU Compiler Collection because the compiler supported several languages beyond C.

A major governance and development milestone was the EGCS fork in 1997, created to merge active GCC development work from several communities. GCC and EGCS were reunified in April 1999, and GCC 2.95 was the first release after that reunification.

採用の歴史

GCC became widely adopted because it was both the GNU system compiler and an openly developed, portable optimizing compiler. The current mission statement emphasizes support for many platforms, many architectures, open mailing lists, and participation by individuals and companies.

The GCC 9 package represents package-manager demand for a stable major compiler series rather than only the newest compiler. Official release branches and tags make these major lines easy for distributors and users to pin, audit, and rebuild.

使われ方

As packaged here, GCC 9 exposes version-suffixed compiler tools such as gcc-9, g++-9, cpp-9, gcov-9, and gfortran-9, depending on the platform package. This lets users select the intended compiler line explicitly in build scripts.

Official GCC installation documentation covers downloading sources, configuring, building, testing, and final installation, while the online manuals document compiler invocation, language front ends, runtime libraries, and toolchain options.

The GCC 9 change notes include package-relevant diagnostic and tooling improvements such as JSON diagnostic output, shell completion support, live-patching options, and source-location display improvements.

パッケージ好きにとっての重要性

Versioned GCC packages matter because compilers are infrastructure, not leaf applications. A build may need a particular major GCC for language support, libstdc++ behavior, Fortran ABI expectations, sanitizer behavior, or target support, while another project on the same machine needs a different line.

The official Git repository page documents release branches and release tags, which is exactly the provenance package maintainers need when mapping formula names such as gcc@12 or gcc@15 to upstream source history.
