Add flags to cc_shared_library for easier debugging

--//examples:incompatible_link_once=False[default = False]
When True, it will be an error to link the same library more than once
unless it has the tag LINKABLE_MORE_THAN_ONCE

--//examples:experimental_debug=True[default = False]
When True, it will generate files listing the exports of each cc_shared_library
and which libraries are linked to it statically.

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(
    ...
)

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
