Windows 上的 gRPC C

新手上路,请多包涵

到目前为止,我已经尝试了 3 天来找到如何在 Windows 上安装和使用 gRPC,但没有成功。我正在使用 Visual Studio 2015,Win7 64 位。为了安全起见,我会一步一步地写我正在做的事情。这可能没有必要,但我是 C++ 和 VS 的初学者,所以我完全不确定我做对了:

(以下指南 http://www.infopulse.com/blog/grpc-framework-by-google-tutorial/ ):

  • 从 git 获取 gRPC,初始化子模块
  • 为 protobuf 获取 gmock 和 gtest (不在指南中,但它不起作用)
  • 在 protobuf 上运行 cmake
  • 在 Visual Studio 中以 Release 模式构建 protobuf.sln (为解决方案的每个部分设置 Property Manager > C/C++ > Code Generation > Runtime Library > /MDd
  • 将 Release/ 文件夹复制到 protobuf/cmake/ (而不是指令中的 Debug/ - 这会给我 libprotobufd.lib 而不是 libprotobuf.lib 这是必需的)
  • 在 VS 中也以发布模式构建 grpc/vsprojects/grpc_protoc_plugins.sln 并再次为解决方案的每个部分设置属性管理器 > C/C++ > 代码生成 > 运行时库 > /MDd
  • 将protobuf/cmake/Release中的 protoc.exe 复制到上一步创建的grpc/vsprojects/Release
  • 在 VS 中以调试模式构建 grpc/vsprojects/grpc.sln (只有 grpc++ 部分,因为我在某处阅读并再次为解决方案的每个部分设置 Property Manager > C/C++ > Code Generation > Runtime Library > /MDd

到目前为止,事情进展顺利。

  • 从示例文件夹中的 proto 生成 c 文件。我得到 helloworld.grpc.pb.cchelloworld.grpc.pb.hhelloworld.pb.cchelloworld.pb.h 并将它们全部移动到 grpc/examples/cpp/helloworld:

protoc –grpc_out=./hello_proto –plugin=protoc-gen-grpc=grpc_cpp_plugin.exe ../../examples/protos/helloworld.proto –proto_path=../../examples/protos

protoc –cpp_out=./hello_proto ../../examples/protos/helloworld.proto –proto_path=../../examples/protos

  • 我在 VS 和“添加”>“新项目”中保持 grpc.sln 打开

  • 到新项目 ‘Add’ > ‘Existing Item’ 并从 grpc/examples/cpp 添加 greeter_client.cc

  • 将依赖项添加为: https ://github.com/grpc/grpc/issues/4707,包含在 C/C++ > 附加包含目录中

当我尝试构建我的项目时,报告了找不到 gflags、gtest 和 libprotobuf 的错误。如果我找到所有内容并将它们移动到包含的文件夹中,那么我会收到以下错误:

在与各种错误斗争了很多天之后,我在这里找到了准备安装的版本 https://github.com/plasticbox/grpc-windows 这似乎对我的目的来说令人满意。我把它贴在这里,以防有人遇到类似情况。

更新:2020 年 6 月

根据 GitHub 上的项目页面,该项目不再维护,因此该示例可能不再适用:

2019 年 5 月 注意:项目不再处于积极开发中,我绝对推荐使用 vcpkg
