# Zig based cross-compiling toolchain

##  Major known issues:

- Zig seems to randomly fail with parallel builds with 'error: unable to build ... CRT file: BuildingLibCObjectFailed'

  This seems like race condition with the cache?

  https://github.com/ziglang/zig/issues/13160

  https://github.com/ziglang/zig/issues/9711

- Rust and zig fight for the ownership of libcompiler_rt

  https://github.com/ziglang/zig/issues/5320

## Why zig for cross-compiling?

Zig can cross-compile out of the box to many target without having to bootstrap the whole cross-compiler and various libcs

This means builds are very fast

# TODO

- Generate meta.json with github actions

   - Rank zig versions and targets depending how well they do in tests

- Provide `zigPkgs` set with packages maintained in this repo

   - Packages that need major restructuring to compile

   - Minimal versions of existing packages (we are mostly interested in libs only)

   - Packages that do not exist yet in nixpkgs

   - Namespaced for different platforms (c, rust, etc...)

   - Generally zigPkgs is expected to compile and work while pkgs from nixpkg can be hit and miss

For other stuff, run `things-to-do`
