The way this repository works is by overlaying itself on top of Zephyr. To get started, first make sure you have Bazel‘s skylib version 1.7.1 or greater. If you don’t have it, you can use:
http_archive(
name = "bazel_skylib",
sha256 = "bc283cdfcd526a52c3201279cda4bc298652efa898b10b4db0837dc51652756f",
urls = [
"https://mirror.bazel.build/github.com/bazelbuild/bazel-skylib/releases/download/1.7.1/bazel-skylib-1.7.1.tar.gz",
"https://github.com/bazelbuild/bazel-skylib/releases/download/1.7.1/bazel-skylib-1.7.1.tar.gz",
],
)
load("@bazel_skylib//:workspace.bzl", "bazel_skylib_workspace")
bazel_skylib_workspace()
To grab the zephyr-bazel repo, use a git_repository rule in your WORKSPACE, such as:
git_repository(
name = "zephyr-bazel",
remote = "https://pigweed.googlesource.com/zephyr/zephyr-bazel"
branch = "main",
)
Once you have @zephyr-bazel, we can load the patch rule to generate the Zephyr diff that will augment Zephyr to include the BUILD.zephyr rules.
load("@zephyr-bazel//:setup.bzl", "create_zephyr_patch_file")
create_zephyr_patch_file(
name = "zephyr-patch",
filename = "patch.diff",
# This is optional, use it to see what's going on under the hood
debug = True,
)
We now have a diff file at @zephyr-patch//:patch.diff. We're ready to load Zephyr.
git_repository(
name = "zephyr",
remote = "https://github.com/zephyrproject-rtos/zephyr.git",
branch = "main",
patches = [
"@zephyr-patch//:patch.diff",
],
)
The final step will be to load Zephyr's python dependencies:
load("@rules_python//python:pip.bzl", "pip_parse")
pip_parse(
name = "py_deps",
python_interpreter_target = interpreter,
requirements_lock = "@@zephyr//:scripts/requirements-base.txt",
)
load("@py_deps//:requirements.bzl", zephyr_install_deps = "install_deps")
zephyr_install_deps()
In your main application, you can now use the Zephyr utilities for building your app.
load("@zephyr//:defs.bzl", "dts_cc_library")
dts_cc_library(
name = "app_native_sim_dts",
dts_lib = "@zephyr//boards/native/native_sim:native_sim",
)
cc_binary(
...
deps = [
...
"@zephyr//:zephyr",
] + select({
"@platform//cpu:x86_64": [
":app_native_sim_dts",
"@zephyr//include:posix",
],
}),
copts = select({
"@platform//cpu:x86_64": [
"-DCONFIG_ARCH_POSIX=1",
],
}),
)
There is currently just 1 example, you can run it via:
$ cd examples/hello_dts $ bazel run :app
Or, you can run the tests via:
$ cd examples/hello_dts $ bazel test //...
