- mongodb - 在 MongoDB mapreduce 中,如何展平值对象?
- javascript - 对象传播与 Object.assign
- html - 输入类型 ="submit"Vs 按钮标签它们可以互换吗?
- sql - 使用 MongoDB 而不是 MS SQL Server 的优缺点
到目前为止,我已经尝试了 3 天来寻找如何在 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是否正确:
(以下指南http://www.infopulse.com/blog/grpc-framework-by-google-tutorial/):
目前一切进展顺利。
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“添加”>“新项目”
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,则会收到以下错误:

如果有人能提供解决方案,我将不胜感激。
最佳答案
在我自己为此苦苦挣扎了一段时间后,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,您可以使用三元组以您想要的方式配置它,例如.\vcpkg.exe 安装 grpc --triplet x86-windows-static
