【bazel】根据.proto文件生成.h、.cc文件

在项目中定义HHHA.proto文件，然后在HHHB.cc或者HHHC.h中直接使用.proto中的定义的“类”——这是可行的。方法是用bazel构建项目时先由HHHA.proto生成中间文件HHHA.pb.cc和HHHA.pb.h。

前提：

•     正确安装bazel，如果没有，请参照这里.

【步骤】

目录结构

├── WORKSPACE
└── src
    ├── BUILD
    └── addressbook.proto

其中，src为包名，因为它包含了BUILD文件

WORKSPACE:

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

http_archive(
    name = "rules_proto",
    sha256 = "602e7161d9195e50246177e7c55b2f39950a9cf7366f74ed5f22fd45750cd208",
    strip_prefix = "rules_proto-97d8af4dc474595af3900dd85cb3a29ad28cc313",
    urls = [
        "https://mirror.bazel.build/github.com/bazelbuild/rules_proto/archive/97d8af4dc474595af3900dd85cb3a29ad28cc313.tar.gz",
        "https://github.com/bazelbuild/rules_proto/archive/97d8af4dc474595af3900dd85cb3a29ad28cc313.tar.gz",
    ],
)
load("@rules_proto//proto:repositories.bzl", "rules_proto_dependencies", "rules_proto_toolchains")
rules_proto_dependencies()
rules_proto_toolchains()

BUILD:

load("@rules_proto//proto:defs.bzl", "proto_library")


cc_library(
    name = "lib",
    deps = [":foo_cc_proto"],
)

cc_proto_library(
    name = "foo_cc_proto",
    deps = [":foo_proto"],
)

proto_library(
    name = "foo_proto",
	srcs = ["addressbook.proto"],
)

addressbook.proto:

syntax = "proto2";

package tutorial;

message Person {
  required string name = 1;
  required int32 id = 2;
  optional string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
  }

  message PhoneNumber {
    required string number = 1;
    optional PhoneType type = 2 [default = HOME];
  }

  repeated PhoneNumber phones = 4;
}

message AddressBook {
  repeated Person people = 1;
}

执行构建：

bazel build src:foo_cc_proto
