Expand tree artifacts in textual_hdrs in generated module maps (#787)

Tree artifacts in a `cc_library`'s `textual_hdrs` end up in the generated module map as a single `header` entry with the directory's path, which fails to parse (`error: header '<dir path>' not found`), instead of one `textual header` entry per contained file. `hdrs` and `srcs` already expand tree artifacts via the module map action's tree expander; this applies the same expansion to the `public_textual_headers` bucket.

Closes #787

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
