Your source for static cross- and native- musl-based toolchains.

toolchains ( linux, windows, mac, solaris, docker, sources, more... )
meta ( config, changelog, matrix )
links ( musl, mingw, risc-v )

Small and reliable pre-built GCC toolchains⁴ for many architectures.
Cross (i686-hosted) by default. Native for completeness.
Static so they run on supported platforms without dependencies.

This site is curl-friendly for direct links to toolchains!

  $ curl -s musl.cc | grep mips
  https://musl.cc/mips-linux-musl-cross.tgz
  ...

Toolchains are built¹ using several modified versions (see below) of musl-cross-make.

For your convenience, Docker images² are provided and updated regularly:

  $ docker pull muslcc/i686:aarch64-linux-musl

Many thanks to others in the #musl and associated communities for making this site possible.
In particular, Rob Landley, Laurent Bercot (skarnet), and of course Rich Felker (dalias).

Bugs discovered:

This effort has led to the discovery of several compiler bugs:

• GCC [87438]: Internal Compiler Error (ICE) building gfortran for MicroBlaze.
• GCC [89012]: Bad code generation targeting SuperH (SH-2 FDPIC).

Known issues:

1. Fortran support is missing from microblaze{,el} cross- and native- toolchains due to an aforementioned bug.
2. Native SH-2 FDPIC toolchains need to be built with -freorder-blocks-algorithm=simple due to an aforementioned bug.
3. OpenRISC target: GCC 8 patched forward from gcc-8_2_0-release to 45d0f2 from here (thanks smaeul). GCC 9 includes it.
4. [meta] Alpine Linux breaks packages between upgrades. Nginx + Lua (for curl support) was broken for a while, sorry.

Other notes:

1. Hashes and cryptographic signatures³ are provided -- use HTTPS for greater security.
2. Versions may be bumped up or down without notice if bugs are discovered.
3. You should pin and reproduce any version of these toolchains yourself -- old binaries might not be archived. Don't trust random third-party binaries :)
4. Build logs are not provided as toolchains are easily reproduced.
5. Looking for i686-hosted cross compilers to target Win32? You're in luck: i686/sig and x86_64/sig (built with this).
6. Native i686- and x86_64- Win32 toolchains. Packaged as .zip for convenience: i686/sig and x86_64/sig (built with this).
7. If you encounter issues or want to request additional architectures, let me know
