Windows上的gRPC C++

我已经尝试了3天，现在找到如何安装和使用gRPC在windows上没有运气。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。这可能不是必要的，但我是C++和VS的初学者，所以我根本不确定我是否正确：
（以下为http://www.infopulse.com/blog/grpc-framework-by-google-tutorial/指南）：

  • 从git获取gRPC，init子模块
  • 获取protobuf的gmock和gtest（指南中没有，但它不起作用）
  • 在protobuf上运行 cmake
  • 在Visual Studio中以发布模式构建 * protobuf.sln *（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Release/文件夹复制到protobuf/cmake/（而不是像介绍中那样的Debug/-这将给予我 libprotobufd.lib 而不是 libprotobuf.lib，这是必需的）
  • 在VS中构建 grpc/vsprojects/grpc_protoc_plugins.sln，并在发布模式下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 * protoc.exe * 从protobuf/cmake/Release复制到grpc/vsprojects/Release，它是在上一步中创建的
  • 在调试模式下在VS中构建 * grpc/vsprojects/grpc.sln *（只有grpc部分，正如我在某处读到的，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）

到目前为止一切都很顺利。

  • 从示例文件夹中的proto生成c文件。我得到 * helloworld.grpc.pb.cc 、helloworld.grpc.pb.h、 helloworld.pb.cc * 和 helloworld.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

  • 我保持 * grpc.sln * 在VS中打开，并'Add' > 'NewProject'
  • 向新项目'Add' > 'Existing Item'添加grpc/examples/cpp中的 greeter_client.cc
  • 将依赖项添加为：https://github.com/grpc/grpc/issues/4707，包含在C/C++ >其他包含目录中

当我尝试构建我的项目时，报告错误，没有找到gflags，gtest和libprotobuf。如果我找到所有文件并将其移动到包含的文件夹中，则会出现以下错误：

如果有人能提供一个解决方案，我将不胜感激。

在我自己为此挣扎了一段时间之后，我发现vcpkg在为Windows构建gRPC C++方面做得非常好。请注意，要求是Window 7或更高版本以及VS2015 Update 3或更高版本。请注意，您可以通过使用三元组来按您想要的方式配置它，例如。.\vcpkg.exe install grpc --triplet x86-windows-static

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，它似乎可以满足我的目的。我把它写在这里，以防有人遇到类似的情况。

更新日期：2020年6月

根据GitHub上的项目页面，该项目已不再维护，因此该示例可能不再工作：
2019年5月注：项目已不再处于积极的开发中，我绝对推荐使用vcpkg

要使用vcpkg安装gRPC，请在Windows中启动控制台并执行以下命令，

  1. vcpkg install grpc:x64-windows
  2. vcpkg install protobuf protobuf:x64-windows
  3. vcpkg install protobuf[zlib] protobuf[zlib]:x64-windows
  4. vcpkg integrate install
    现在我们已经拥有了所需的一切，因此让我们尝试使用protoc编译器从proto文件生成消息和服务接口
    如果protoc在您的控制台上不可用，您可能必须将其添加到系统env PATH中。它将出现在您的<vcpkg_install_path>\packages\protobuf_x64-windows\tools\protobuf文件夹中
    现在将文件复制到我们的project/proto文件夹，并从那里运行以下命令
  5. protoc -I=. --cpp_out=. <yourprotofile>.proto
  6. protoc -I=. --grpc_out=. --plugin=protoc-gen-grpc="<vcpkg_install_path>\packages\grpc_x64-windows\tools\grpc\grpc_cpp_plugin.exe" <your_protofile>.proto
    现在让我们将内容添加到CMakeLists.txt文件中。将下面的代码复制到CMakeLists.txt文件中。
//  start  //

cmake_minimum_required( VERSION 3.1 )

project( grpc_example )

find_package(gRPC CONFIG REQUIRED)

find_package( Protobuf REQUIRED )

include_directories(<vcpkg_install_path>/buildtrees/protobuf/src/23fa7edd52-3ba2225d30.clean/src)

add_executable( server src/server.cpp proto/helloworld.grpc.pb.cc proto/helloworld.pb.cc)

add_executable( client src/client.cpp proto/helloworld.grpc.pb.cc proto/helloworld.pb.cc)

target_link_libraries( server PRIVATE gRPC::grpc++ gRPC::grpc++_reflection gRPC::gpr gRPC::grpc gRPC::grpc++ gRPC::grpc_cronet protobuf::libprotoc protobuf::libprotobuf protobuf::libprotobuf-lite )

target_link_libraries( client PRIVATE gRPC::grpc++ gRPC::grpc++_reflection gRPC::gpr gRPC::grpc gRPC::grpc++ gRPC::grpc_cronet protobuf::libprotoc protobuf::libprotobuf protobuf::libprotobuf-lite )

// end //

现在转到我们的project/build文件夹，发出以下命令，使用CMake生成一个项目。我将在这里生成一个Visual Studio 2015解决方案，但选择取决于你。

  1. cmake -G "Visual Studio 14 2015 Win64" ../ -DCMAKE_TOOLCHAIN_FILE=<vcpkg_install_path>/scripts/buildsystems/vcpkg.cmake
  2. cmake build .
  3. cmake --build . --config Release
    现在转到Release文件夹，然后运行server.exe和client.exe

这帮了我很多，谢谢你做了这个。我用这个通过解压缩压缩，光盘在文件夹和与

git clone -b v1.2.0 https://github.com/grpc/grpc

git submodule update --init

将pthreads安装到Visual Studio VC\include（.h）、lib（.lib）和bin（.dll）
运行nuget restore（foreach.sln文件以获取依赖项）

nuget restore grpc\vsprojects\grpc.sln

nuget restore grpc\vsprojects\grpc_protoc_plugins.sln

nuget restore grpc\third_party\protobuf\cmake\build\solution\protobuf.sln

修复grpc\src\cpp\server\ server_builder.cc

int num_frequently_polled_cqs = sync_server_cqs->size();

将第273行中的int改为size_t，int num...（同上）
运行grpc_build.bat，然后转到grpc_helloworld文件夹并运行test_protoc. bat，打开grpc_helloworld. sln，运行build应该会自动执行nuget。

我按照BUILDING.MD的指示做了。你也可以在这里查看：https://github.com/grpc/grpc/blob/master/BUILDING.md

  • 我用git clone -b v1.55.0 https://github.com/grpc/grpc克隆了grpc存储库
  • 命令git submodule update --init失败，我不得不手动删除/third_party/opencensus-proto
  • 我需要运行git rm --cached third_party/opencensus-proto这一步可能是不需要的，当目录被删除之前运行git子模块，然后我就能够得到丢失的子模块
  • Visual Studio使用cmake .. -G "Visual Studio 17 2022"

然后我就可以按照Windows的进一步说明操作了
