A util script that aims to ease use zig cc to compile C/C++/Rust/Go programs.

In most cases, we can use following command to use Zig for compile

CC='zig cc' CXX='zig c++' ...

However in real world, there are many issues this way, such as:

• zig cc: parse -target and -mcpu/-march/-mtune flags according to clang #4911
• Targets compare: Rust to Zig
• unsupported linker arg
• Rust + `zig cc` CRT conflict. : rust

So this project was born, it will

• Convert target between Zig and Rust/Go
• Ignore link args when zig cc throw errors, hopefully this will make compile successfully, WIP.

pip install -U zigcc

This will install three executables:

• zigcc, used for CC
• zigcxx, used for CXX
• zigcargo can used to replace cargo, it will automatically set
  • CC CARGO_TARGET_<triple>_LINKER to zigcc
  • CXX to zigcxx

Adding a step to your workflow like this:

- uses: jiacai2050/zigcc@main
  with:
    zig-version: master

Then you can invoke zigcc zigcxx zigcargo in following steps.

There some are env variable to config zigcc:

• ZIGCC_FLAGS, space separated flags, pass to zig cc. An example is set this to -fno-sanitize=undefined to disable sanitize since they may break your programs. See Catching undefined behavior with zig cc
• ZIGCC_BLACKLIST_FLAGS, space separated flags, used to filter flags zig cc don’t support, such as -Wl,-dylib otherwise you could see errors below

  = note: error: unsupported linker arg: -dylib
      

• ZIGCC_VERBOSE Set to 1 enable verbose logs.
