- At the AGM we formed an ad-hoc documentation working group. - One of our ideas was that we should have a last reviewed date for documentation, so that we can periodically implement a review mechanism (GitHub Actions posts to Slack for a regular documentation outdatedness check?) to track how old docs are and ensure they're still relevant. - This is a first step towards that goal, by adding a `last_review_date` to the metadata of all docs with a date of earlier than Homebrew's inception because everything needs reviewing so that we start from a good base!

# Custom GCC and Cross Compilers
|
|
|
|
Homebrew depends on having an up-to-date version of Xcode because it comes with specific versions of build tools, e.g. `clang`. Installing a custom version of GCC or Autotools into your `PATH` has the potential to break lots of compiles so we prefer the Apple- or Homebrew-provided compilers. Cross compilers based on GCC will typically be "keg-only" and therefore not linked into your `PATH` by default, or be prefixed with the target architecture, again to avoid conflicting with Apple or Homebrew compilers.
|
|
|
|
Rather than merging formulae for either of these cases at this time, we're listing them on this page. If you come up with a formula for a new version of GCC or cross-compiler suite, please link to it here.
|
|
|
|
- Homebrew provides a `gcc` formula for use with Xcode 4.2+.
|
|
- Homebrew provides older GCC formulae, e.g. `gcc@9`.
|
|
- Homebrew provides some cross-compilers and toolchains, but these are named to avoid clashing with the default tools, e.g. `i686-elf-gcc`, `x86_64-elf-gcc`.
|
|
- Homebrew provides LLVM's Clang, which is bundled with the `llvm` formula.
|
|
- [RISC-V](https://github.com/riscv/homebrew-riscv) provides the RISC-V toolchain including binutils and GCC.
