Compile Cargo project with zig as linker for easier cross compiling.
cargo install cargo-zigbuild
You can also install it using pip which will also install ziglang
automatically:
pip install cargo-zigbuild
We also provide a Docker image which has macOS SDK pre-installed in addition to cargo-zigbuild and Rust, for example to build for x86_64 macOS:
docker run --rm -it -v $(pwd):/io -w /io messense/cargo-zigbuild \
cargo zigbuild --release --target x86_64-apple-darwin
- Install zig following the official documentation,
on macOS, Windows and Linux you can also install zig from PyPI via
pip3 install ziglang
- Install Rust target via rustup, for example,
rustup target add aarch64-unknown-linux-gnu
- Run
cargo zigbuild
, for example,cargo zigbuild --target aarch64-unknown-linux-gnu
cargo zigbuild
supports passing glibc version in --target
option, for example,
to compile for glibc 2.17 with the aarch64-unknown-linux-gnu
target:
cargo zigbuild --target aarch64-unknown-linux-gnu.2.17
- Currently only Linux, macOS and Windows gnu targets are supported, other target platforms can be added if you can make it work, pull requests are welcome.
- Only current Rust stable and nightly versions are regularly tested on CI, other versions may not work.
Known upstream zig issues:
- zig cc: parse
-target
and-mcpu
/-march
/-mtune
flags according to clang: Some Rust targets aren't recognized byzig cc
, for examplearmv7-unknown-linux-gnueabihf
- glibc 2.27 or older: fcntl64 not found, but zig's glibc headers refer it
