# Bazel Support

${ '##' } Basic Usage
|
|
|
|
|
|
|
|
|
|
The `grpc/grpc` repository's primary build system is Bazel. Rules are provided
|
|
|
|
|
for C++, Python, and Objective-C. While C++ supports other build systems such as
|
|
|
|
|
CMake, these rules are actually generated from the Bazel definitions.
|
|
|
|
|
|
|
|
|
|
Projects built with Bazel may use the `grpc/grpc` repo not only to add a
|
|
|
|
|
dependency on the library itself, but also to generate protobuf, stub, and
|
|
|
|
|
servicer code. To do so, one must invoke the `grpc_deps` and `grpc_extra_deps`
|
|
|
|
|
repository rules in their `WORKSPACE` file:
|
|
|
|
|
|
|
|
|
|
```starlark
|
|
|
|
|
workspace(name = "example_workspace")
|
|
|
|
|
|
|
|
|
|
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
|
|
|
|
|
|
|
|
|
|
http_archive(
|
|
|
|
|
name = "com_github_grpc_grpc",
|
|
|
|
|
strip_prefix = "grpc-1.45.0",
|
|
|
|
|
sha256 = "ec19657a677d49af59aa806ec299c070c882986c9fcc022b1c22c2a3caf01bcd"k
|
|
|
|
|
urls = ["https://github.com/grpc/grpc/archive/refs/tags/v1.45.0.tar.gz"],
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
load("@com_github_grpc_grpc//bazel:grpc_deps.bzl", "grpc_deps")
|
|
|
|
|
|
|
|
|
|
grpc_deps()
|
|
|
|
|
|
|
|
|
|
load("@com_github_grpc_grpc//bazel:grpc_extra_deps.bzl", "grpc_extra_deps")
|
|
|
|
|
|
|
|
|
|
grpc_extra_deps()
|
|
|
|
|
```

${ '##' } Supported Versions
|
|
|
|
|
|
|
|
|
|
In general, gRPC supports building with the latest patch release of the two most
|
|
|
|
|
recent LTS versions of Bazel. However individual releases may have a broader
|
|
|
|
|
compatibility range. The currently supported versions are captured by the
|
|
|
|
|
following list:
|
|
|
|
|
|
|
|
|
|
% for version in supported_bazel_versions:
|
|
|
|
|
- [`${version}`](https://github.com/bazelbuild/bazel/releases/tag/${version})
|
|
|
|
|
% endfor
