Change cc_shared_library exports logic.

Changes in this CL:
1. 'exports' attribute renamed to roots
2. Removed restrictions for exporting a rule in a different repository
3. Kept restrictions for rules in the same repository but not in the same
package or subpackages
4. To get around restrictions, instead of the exported_by tag, one can use the
cc_shared_library_permissions rule
5. Added exports_filter that will match libraries in the transitive closure of
a root. Anything matched by the exports_filter will also be exported.
Restrictions as in 4. still apply.

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
