Googler c460f83acb Include more information about configurations in cquery proto formatted outout 
1. Add a repeated Configuration field to CqueryResult, and fill in the
checksum, platform, and mnemonic fields.

2. Add a configuration_id field to ConfiguredTarget, and deprecate the existing
configuration field in ConfiguredTarget. The configuration_id field is an index
that points to the Configuration message stored in CqueryResult, following the
same pattern as ActionGraphContainer. This avoids duplicating the same
Configuration message for each ConfiguredTarget.

RELNOTES: Include more information about configurations in cquery proto
formatted output. This deprecates the configuration field of
AnalysisProtosV2.ConfiguredTarget, and adds a new field, configuration_id, to
be used instead.

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/TODO"],
    sha256 = "TODO",
)

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
