Add missing bsd link libraries (#859)

This mirrors this behavior from the clang driver:

https://github.com/llvm/llvm-project/blob/3e892fad65730692057da27bebb2e34d3ad7bde7/clang/lib/Driver/ToolChains/OpenBSD.cpp#L365-L366

The same does not apply for freebsd (I didn't check netbsd which isn't
supported here right now).

Alternatively we could use clang++ for linking directly instead of
clang, which would add these automatically, but that would make it
harder to disable these in the case you are linking pure C

Fixes https://github.com/bazelbuild/rules_cc/issues/857

Closes #859

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
