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:
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()
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:
