This is **not an officially supported Google product**
2018-04-26 17:52:06 +00:00
(meaning, support and/or new releases may be limited.)
## Documentation
Documentation for all rules and providers are available at: https://bazelbuild.github.io/rules_foreign_cc/
## Bazel versions compatibility
2022-11-09 11:54:39 +00:00
Works with Bazel after 4.0.0.
The following flags are required in Bazel 4.x but not Bazel 5.x or newer:
- `--experimental_enable_aggregating_middleman=False`
Note that the rules may be compatible with older versions of Bazel but support may break
in future changes as these older versions are not tested.

## Caveats
* FreeBSD support is currently experimental and on a best-effort basis.
Google currently doesn't have a CI test environment for FreeBSD,
but please make your voice heard by upvoting this
