Reuse Starlark default features in CcToolchainInfo

Copybara Import from https://github.com/bazelbuild/rules_cc/pull/807

BEGIN_PUBLIC
Reuse Starlark default features in CcToolchainInfo (#807)

Use `CcToolchainConfigInfo._default_features_and_action_configs` when initializing the C++ toolchain provider. `create_cc_toolchain_config_info` already computes this ordered list in Starlark, so the remaining `CcToolchainFeatures.default_features_and_action_configs()` Java call is unnecessary.

Validation: `buildifier -mode=check cc/private/rules_impl/cc_toolchain_provider_helper.bzl` and 89 passing C++ common, binary, and library analysis tests.

Closes #807

C++ rules for Bazel

  • Postsubmit Build status

This repository contains C, C++, and Objective-C language support for the Bazel build system.

For this module's main reference, see the Bazel documentation.

Get Started

Install Bazel

Follow the official instructions to Install Bazel.

Add rules_cc to your MODULE.bazel

Add the latest release to your MODULE.bazel project file.

Declare a build target

In a BUILD.bazel file, import and use the rules:

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

cc_binary(
    name = "hello_world",
    srcs = ["hello_world.cc"],
)

Build and run your project

Build and run your C/C++ binary with one command:

$ bazel run hello_world

To build the project without running the binary, use Bazel's build subcommand:

$ bazel build hello_world

Toolchains

Default autoconfigured toolchain

rules_cc includes an auto-configured toolchain that uses the local compiler installed on the host machine.

You can disable the autoconfigured C/C++ toolchain by adding the following Bazel flag to your project's .bazelrc file:

--repo_env=BAZEL_DO_NOT_DETECT_CPP_TOOLCHAIN=1

Hermetic toolchains

Configuring a hermetic toolchain makes your build more deterministic. rules_cc itself does not yet offer a hermetic toolchain distribution. Other community owned and maintained projects offer hermetic C/C++ toolchains:

Contributing
