## What it is
Homebrew tap distributing precompiled GCC cross-compiler toolchains for targeting Linux (x86_64 and aarch64) from macOS, supporting both Apple Silicon and Intel Macs. It is commonly used to cross-compile Rust projects with Cargo by setting the appropriate linker environment variables.

## Use cases
- cross-compile Rust binaries for Linux from a Mac
- install a Linux GCC toolchain on macOS via Homebrew
- build x86_64-unknown-linux-gnu binaries on Apple Silicon
- set up CARGO_TARGET linker for cross-compilation
- compile C/C++ code for aarch64 Linux from macOS

## When to choose
- you develop on macOS and need to build Linux binaries without a VM or CI
- you want precompiled cross toolchains installable via Homebrew
- you cross-compile Rust crates with native C dependencies

## When to avoid
- you need to cross-compile targeting macOS from Linux or Windows
- you require MSVC or Windows target toolchains
- you need a fully supported, officially blessed toolchain with a license guarantee

## Facets
- artifact type: cli-tool

- function: compiler, build-tool, developer-tools
- domain: developer-tools, compilers, cross-platform
