Windows上的gRPC C

Question

到目前为止，我已经尝试了三天，想知道如何在windows上安装和使用gRPC，但运气不好。我使用的是Visual Studio 2015，Win7 64位。为了安全起见，我会一步一步地写下我正在做的事情。这可能没有必要，但我是C和VS的初学者，所以我根本不确定我做得是否正确：

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

• 从git获取gRPC，init子模块
• 获取gmock和gtest for Pro buf（不在指南中，但它不起作用）
• 在Pro buf上运行cmake
• 以发布模式在Visual Studio中构建protobuf.sln（为解决方案的每个部分设置属性管理器

到目前为止，事情进展顺利。

protoc—grpc\U out=/hello\u proto--plugin=protoc gen grpc=grpc\u cpp\u plugin。exe..//示例/protos/helloworld。proto—proto\u路径=..//示例/原型

protoc—cpp\U out=/您好\u proto..//示例/protos/helloworld。proto—proto\u路径=..//示例/原型

我在VS和'Add'中保持grpc.sln打开

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

如果有人能提供解决方案，我将不胜感激。

Answer 1

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安装grpc：x64-windows
2. vcpkg安装原型：x64-windows
3. vcpkg安装协议包[zlib]协议包[zlib]：x64-windows
4. vcpkg集成安装

现在我们拥有了所需的一切，所以让我们尝试使用proto编译器从proto文件生成消息和服务接口

如果控制台上没有协议，您可能必须将其添加到您的系统环境路径中。它将出现在您的中

现在将文件复制到我们的项目/proto文件夹中，并从那里运行以下命令

>

协议-我=.--cpp_out=.

协议I=--grpc\U out=--插件=protoc gen grpc=”

现在让我们将内容添加到我们的CMakeLists.txt文件中。获取以下代码并将其复制到我们的CMakeLists.txt文件中。

//  start  //
