Building NativeLink with Bazel

These instructions contain information on how to work with NativeLink for Bazel users.

If you’re using the Nix flake you’re all set.

If you’re running outside of nix, install bazelisk manually and make sure you have a recent functional C++ toolchain with LLD as linker.

Build

The following commands places an executable in ./bazel-bin/nativelink and starts the service:

Unix

bazel run nativelink -- \
    $(pwd)/nativelink-config/examples/basic_cas.json

Windows

bazel run --config=windows nativelink -- \
    $(pwd)/nativelink-config/examples/basic_cas.json

For optimized builds:

Unix

bazel run -c opt nativelink -- \
    $(pwd)/nativelink-config/examples/basic_cas.json

Windows

bazel run --config=windows -c opt nativelink -- \
    $(pwd)/nativelink-config/examples/basic_cas.json

Caution

The Rust compiler rustc generates large artifacts during compilation, including dependencies, macros, and intermediate files. When compiling programs from source, be mindful of the associated files’ impact on your disk usage in the bazel-bin/ directory.

If you’re facing issues due to this, run the following command to clear cache files:

bazel clean --expunge

Test

To run tests with Bazel:

Unix

bazel test //... --verbose_failures

Windows

bazel test --config=windows //... --verbose_failures
