Rules Foreign CC Examples
Top-Level
Top-level examples should contain no dependencies outside of rules_foreign_cc directly and anything else in
it's directory. The directories should be prefixed with the type of rule they're associated with. Eg
cmake_with_data (being a cmake_external example) and configure_with_bazel_transitive
(being a configure_make example).
Third Party
Examples of building source from outside of rules_foreign_cc should be put in the third_party directory
which is an isolated workspace that gets added to rules_foreign_cc_examples as an additional
rules_foreign_cc_examples_third_party repository. In general, these are expected to be expensive to build
so adding new things here should be done selectively. In the top-level package of this workspace, there are
test suites separated by the operating system that all tests need to be registered with. The expected structure of
any example in this workspace are as follows:
third_party/lib
├── BUILD.bazel
├── BUILD.lib.bazel
└── lib_repositories.bzl
BUILD.bazel
This file must contain some sort of test that confirms the targets for the external repo can be successfully
built and ideally ran. The targets here will need to be registered in the test_suite's found in
./third_party/BUILD.bazel or they will not be ran in CI.
BUILD.lib.bazel
The BUILD file expected to be used in the repository containing the target source code.
lib_repositories.bzl
A file containing a single macro lib_repositories that should define the desired repository and ensure the
BUILD.lib.bazel file will correctly be installed when the repository is setup. This macro will need to be
loaded and called in third_party/repositories.bzl.
