在Windows上使用gRPC C++

c++windowsvisual-studio-2015grpc
26
我已经努力寻找在Windows上安装和使用gRPC的方法三天了，但一直没有成功。 我正在使用Visual Studio 2015和Win7 64位操作系统。为了保险起见，我将逐步描述我的操作步骤。这可能并不是必要的，但我是一个C++和VS的初学者，所以我不确定我的操作是否正确。(按照指南http://www.infopulse.com/blog/grpc-framework-by-google-tutorial/进行)。
从 git 获取 gRPC，初始化子模块
为 protobuf 获取 gmock 和 gtest（指南中没有提到，但否则无法正常工作）
在 protobuf 上运行 cmake 在 Visual Studio 中以 Release 模式构建 protobuf.sln（对于解决方案的每个部分，在 Property Manager 中设置 C/C++ > Code Generation > Runtime Library > /MDd）
将 Release/ 文件夹复制到 protobuf/cmake/ 中（而不是按照说明中的 Debug/，这会给我 libprotobufd.lib 而不是所需的 libprotobuf.lib）
同样以 Release 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 Property Manager > C/C++ > Code Generation > Runtime Library > /MDd
将 protobuf/cmake/Release 中的 protoc.exe 复制到先前创建的 grpc/vsprojects/Release 中
在 Visual Studio 中以 Debug 模式构建 grpc.sln（仅构建 grpc++ 部分，因为我在某个地方读到过，并且再次为解决方案的每个部分设置 Property Manager > C/C++ > Code Generation > Runtime Library > /MDd）

目前情况良好。

  • 从示例文件夹中的proto生成c文件。我得到了helloworld.grpc.pb.cc，helloworld.grpc.pb.h，helloworld.pb.cc和helloworld.pb.h，然后将它们全部移动到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中保持grpc.sln打开状态，并选择'添加' > '新建项目'

  • 对于新项目，'添加' > '现有项'，并添加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++ > 附加包含目录中
当我尝试构建我的项目时，会报告找不到gflags、gtest和libprotobuf的错误。如果我找到它们并将它们移动到一个包含的文件夹中，那么我会得到以下错误：

错误已经消失了，尽管出现了新的问题 - /ZI 和 /GL 不兼容。这可能是可以解决的错误。与 Debug 和 Release 混合不同，它不起作用（可能会编译，但由于不兼容的 CRT，在运行时很可能会导致崩溃）。 - drescherjm

这可能不是必要的，但我是一个C语言的初学者。两件事情：1.一般来说，更多的信息是好的，所以要表扬。我们想看看你采取了哪些步骤 :) 2.C语言不是C++，确保术语命名正确！ - Qix - MONICA WAS MISTREATED

在自己苦苦摸索一段时间之后，我发现 vcpkg 在 Windows 下构建 gRPC C++ 非常出色。请注意，要求使用 Window 7 或更高版本以及 VS2015 Update 3 或更高版本。此外，您可以通过使用三元组将其配置为所需的方式，例如 .\vcpkg.exe install grpc --triplet x86-windows-static。

在经历了多天的各种错误后，我找到了这里 https://github.com/plasticbox/grpc-windows 一个已经准备好安装的版本，它似乎能够满足我的需求。我在这里发布以便有任何类似情况的人可以使用。

更新：2020年6月

根据GitHub上项目页面的说明，该项目不再维护，因此示例可能不再有效：

2019年5月注意：项目不再处于积极开发中，我强烈推荐使用vcpkg

在与GRPC/Protobuf挣扎了一天之后，我终于找到了这篇文章，它拯救了我的理智。太棒了！ - Optional Option
我不需要苦苦挣扎，因为我在这篇文章中找到了这些好用的脚本（感谢作者），并使用它们在 Windows 10 64位系统上构建了 protobuf3 和 grpc。谢谢！ - Dess
我做了几天相同的事情，然后我看到了这篇文章...在Github上给他一个星星！ - Stefano Piovesan

注意，提到的脚本构建的是相当旧的 gRPC 的“v1.3.x”版本，而 gRPC 团队已经改变了构建方式，所以请小心！ - Thomas

如果您想要构建一个新版本的grpc或使用更新版本的Visual Studio构建，请查看上述github项目的一些分支。 - jonathanjg

@jonathanjg，如果看到大多数的这些fork都是因为用户不小心点击了fork按钮，而本来是想查看现有的fork，那我也不会太惊讶 ;) - Andreas

为了使用vcpkg安装gRPC，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
现在我们拥有了所需的所有内容，让我们尝试使用protoc编译器从proto文件生成消息和服务接口。
如果您的控制台中没有可用的protoc，则可能需要将其添加到系统环境变量PATH中。它将存在于<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文件夹中，并从那里运行以下命令。

  1. protoc -I=. --cpp_out=. <yourprotofile>.proto

  2. protoc -I=. --grpc_out=. --plugin=protoc-gen-grpc="<vcpkg_install_path>\packages\grpc_x64-windows\tools\grpc\grpc_cpp_plugin.exe" <your_protofile>.proto

现在让我们向我们的CMakeLists.txt文件添加内容。取以下代码并将其复制到我们的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，请进入我们的项目/构建文件夹，并发出以下命令，使用CMake生成一个项目。我将在此处生成Visual Studio 2015解决方案，但选择权在于您。

  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，并运行server.exe和client.exe。

你好，cmake部分是必需的吗？我以为vcpkg已经提供了一切可以在Visual Studio中使用的东西？我试图跳过cmake部分，但现在我卡在链接器错误上了：https://stackoverflow.com/questions/68768805/lnk2001-and-lnk2019-for-grpc-installed-via-vcpkg?noredirect=1&lq=1 - OneWorld

回答之前的评论：不，这并非必要。可以省略您回答中的cmake部分，在VisualStudio中使用基于MSBuild的项目（即常规控制台cpp项目）。但是，基于MSBuild的项目存在链接器错误，需要通过以下方式进行修复：https://stackoverflow.com/questions/68768805/still-linker-errors-in-visualstudio-for-grpc-despite-autolink-vcpkg-enabled/68772745#68772745 - OneWorld

以下是我在Windows上安装和使用grpc的解决方案...
GRPC C++... 安装... Microsoft Visual Studio Community 2017 版本15.6.4 Git CMake Chocolatey 以管理员身份打开git Active State Perl choco install activeperl Go choco install golang yasm choco install yasm 将C:\ProgramData\chocolatey\lib\yasm\tools添加到PATH Ninja choco install ninja 克隆包括子模块在内的grpc源码... git clone --recursive -b v1.10.x https://github.com/grpc/grpc cd grpc cmake：使用Ninja（支持boringssl的汇编优化）... 关闭git 打开管理员：命令提示符（shift+RC cmd并以管理员身份运行） cd C:\Users\aaron\repo\grpc md .build && cd .build call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" x64 cmake .. -GNinja -DCMAKE_BUILD_TYPE=Release cmake --build . ninja install
生成代码... 打开Visual Studio并创建新项目 关闭预编译头文件 RC项目 -> 属性 -> C/C++ -> 预编译头文件 设置预编译头文件="不使用预编译头文件" 删除stdafx.h/.cpp 添加.proto文件 RC资源文件 -> 添加新文件 -> 实用程序 -> Text.txt 使用.proto扩展名命名文件 编写.proto文件内容 将.proto文件复制到"C:\Program Files (x86)\grpc\bin" 导航到"C:\Users\aaron\repo\grpc\.build" 将grpc_cpp_plugin.exe复制到"C:\Program Files (x86)\grpc\bin" 打开管理员：命令提示符 cd C:\Program Files (x86)\grpc\bin protoc -I . --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin.exe cid_service.proto 生成cid_service.grpc.pb.cc/.h protoc -I . --cpp_out=. cid_service.proto 生成cid_service.pb.cc/.h 将文件复制到VS项目并将它们添加到Header Files/Source Files。

这对我很有帮助，谢谢你制作这个。我通过解压缩zip文件，在文件夹中使用cd命令来使用它。
git clone -b v1.2.0 https://github.com/grpc/grpc

git submodule update --init

将pthreads安装到Visual Studios VC\include(.h)、lib(.lib)和bin(.dll)中

运行nuget restore（对于每个.sln文件获取依赖项）

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行的int改为size_t，num...(如上所述)
运行grpc_build.bat，然后进入grpc_helloworld文件夹并运行test_protoc.bat，打开grpc_helloworld.sln，运行构建应该会自动执行nuget。

我按照 BUILDING.md 中的说明进行操作。您也可以在此处查看: https://github.com/grpc/grpc/blob/master/BUILDING.md

  • 我使用 git clone -b v1.55.0 https://github.com/grpc/grpc 克隆了 grpc 存储库
  • 命令 git submodule update --init 失败了，我不得不手动删除 /third_party/opencensus-proto 目录
  • 我需要运行 git rm --cached third_party/opencensus-proto 这一步骤可能在运行 git submodule 之前删除目录时不需要，然后我就能获取缺失的子模块了
  • 我使用 cmake .. -G "Visual Studio 17 2022" 在 Visual Studio 中进行操作

然后我就能按照 Windows 的进一步说明进行操作了。
