Bazel resolved third party dependencies. The purpose of this repository is to provide bazel-native (or tuned rules_foreign_cc definitions) for various third party repositories across Linux, Windows and MacOS.

There is plenty of software that is generally useful that do not support the bazel build system. rules_foreign_cc addresses this problem only partially right now (and possibly won't ever fully address the problem with certain classes of build system Ie. configure/build) in that it tends to have problems operating on platforms that aren't Linux. Sometimes it can be made to work, but sometimes assumptions are made about the build environment that do not work well in bazel causing build failures.

Ultimately we want easy to access bazel libraries that work across at least Linux, Windows and MacOS.

Add the following to your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:utils.bzl", "maybe")
load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

maybe(
    git_repository,
    name = "rules_third_party",
    remote = "https://github.com/DraconicEnt/rules_third_party.git",
    commit = "512b473cb80586381f6c14102cc6c8b0f118e0f7" # Change to any commit ID you want
)

To load and initialize a third party dependency (zlib here for example), also add the following to your WORKSPACE:

load("@third_party//libraries:zlib.bzl", "zlib")

zlib()

For more information about supported libraries and their associated documentation, see the wiki.

These rules are all defined using the maybe directive. This means you can load alternative versions of the software supported by this repository. For example, you can load ENet 1.3.10 (instead of the 1.3.17) using the following code:

load("@bazel_tools//tools/build_defs/repo:utils.bzl", "maybe")
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

maybe(
    http_archive,
    name = "enet",
    urls = [
        "https://github.com/lsalzman/enet/archive/v1.3.10.tar.gz"
    ],
    sha256 = "035f9b5cdc67b720a45952b77a28fdf054e93fd273df9dd7f6a3e13d60571069",
    build_file = "@rules_third_party//libraries:enet.BUILD"
)

# You should still load and call the initialization function, though, so that all subdependencies are initialized
# but only do this AFTER your declaration above.
load("@third_party//:libraries/enet.bzl", "enet")
enet()

The following assumptions are made about your build environment:

• Your build host is either Windows, Linux or MacOS.
