Simplify WORKSPACE setup and update ancient deps

By removing a single unused `bzl_library` target, rules_cc no longer has
any dependencies that would need to be loaded by a dependency macro. The
existing macro is made a no-op.

The few needed Bazel Federation dependencies are inlined and, in the
case of bazel_skylib and abseil-py, updated to modern versions.

Also reorders `WORKSPACE` to list direct dependencies first and keeps
`MODULE.bazel` in sync with the dependency versions used in WORKSPACE.

The `ubuntu1604` CI pipeline is removed as the version of Python used by
it is no longer supported and the distribution is EOL. Instead, a new
pipeline is added to check the Bzlmod build.

C++ rules for Bazel

  • Postsubmit Build status
  • Postsubmit + Current Bazel Incompatible flags Build status

This repository contains Starlark implementation of C++ rules in Bazel.

The rules are being incrementally converted from their native implementations in the Bazel source tree.

For the list of C++ rules, see the Bazel documentation.

Getting Started

There is no need to use rules from this repository just yet. If you want to use rules_cc anyway, add the following to your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_cc",
    urls = ["https://github.com/bazelbuild/rules_cc/archive/refs/tags/<VERSION>.tar.gz"],
    sha256 = "...",
)

Then, in your BUILD files, import and use the rules:

load("@rules_cc//cc:defs.bzl", "cc_library")

cc_library(
    ...
)

Using the rules_cc toolchain

If you'd like to use the cc toolchain defined in this repo add this to your WORKSPACE after you include rules_cc:

load("@rules_cc//cc:repositories.bzl", "rules_cc_dependencies", "rules_cc_toolchains")

rules_cc_dependencies()

rules_cc_toolchains()

Migration Tools

This repository also contains migration tools that can be used to migrate your project for Bazel incompatible changes.

Legacy fields migrator

Script that migrates legacy crosstool fields into features (incompatible flag, tracking issue).

TLDR:

bazel run @rules_cc//tools/migration:legacy_fields_migrator -- \
  --input=my_toolchain/CROSSTOOL \
  --inline
