编译

参考https://github.com/google/protobuf/blob/master/cmake/README.md

1. 需要cmake, git, vs
2. Native Tools Command Prompt

1. %comspec% /k "d:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\VsDevCmd.bat"

1. 下载https://github.com/google/protobuf/releases中的protobuf-cpp-3.5.0.zip
2. 解压，cmd进入目录

1. E:\LIBS\Protobuf\protobuf-3.5.0
2. E:
3. mkdir install

1. 确认环境中有cmake和bit，如果没有

1. If cmake command is not available from Command Prompt, add it to system PATH variable:
2. C:\Path\to>set PATH=%PATH%;C:\Program Files (x86)\CMake\bin
4. If git command is not available from Command Prompt, add it to system PATH variable:
5. C:\Path\to>set PATH=%PATH%;C:\Program Files\Git\cmd

1. 开始cmake，下面命令执行后会看到Makefile文件

1. cd cmake
2. mkdir build & cd build
4. ;make release
5. mkdir release & cd release
6. cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../../../../install ../..
8. ;make debug（跳回上层build目录）
9. mkdir debug & cd debug
10. cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../../../../install ../..
12. ;To create Visual Studio solution file:
13. mkdir solution & cd solution
14. ;如果出现问题，说不存在可以用cmake --help看看是否支持。不支持高版本的vs，就要升级cmake了。
15. ;cmake -G "Visual Studio 12 2013 Win64" -DCMAKE_INSTALL_PREFIX=../../../../install ../..
16. cmake -G "Visual Studio 15 2017 Win64" -DCMAKE_INSTALL_PREFIX=../../../../install ../..

1. 7. 编译

打开protobuf.sln选择release还是debug，右键解决方案—->生成解决方案

1. 生成INSTALL—会在最外层的install文件夹生成结果E:/LIBS/Protobuf/install

   在解决方案里右键INSTALL生成

1. This will create the following folders under the install location:
3. bin - that contains protobuf protoc.exe compiler;
4. include - that contains C++ headers and protobuf *.proto files;
5. lib - that contains linking libraries and CMake configuration files for protobuf package.

使用

1. cd F:\MyPrivateProjects\Git\LearnCpp\LearnProtobuf\LearnProtobuf
2. F:
3. F:\MyPrivateProjects\Git\LearnCpp\LearnProtobuf\LearnProtobuf\google\bin\protoc.exe
5. protoc.exe --cpp_out=addressbook/ addressbook.proto

1. --cpp_out
2. --java_out
3. --python_out
4. --javanano_out
5. --php_out
6. --ruby_out
7. --csharp_out
8. --objc_out
9. --js_out
