Migrate away from compilation_outputs.files_to_compile

The same information is available in other fields.

This prevents regression when compilation_outputs are rewritten to Starlark.

C++ rules for Bazel

  • Postsubmit Build status

This repository contains a 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

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

This repo contains an auto-detecting toolchain that expects to find tools installed on your host machine. This is non-hermetic, and may have varying behaviors depending on the versions of tools found.

There are third-party contributed hermetic toolchains you may want to investigate:

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
