编译处理工具指导

消息协议处理工具

---

这个目录保存协议文件.proto以及相应的处理工具

所需环境

• 需要安装Python3.x版本来运行编译脚本，请到Python官网 下载安装，安装之后确认python --version命令能正确执行

编译proto 对应的c# c++指导方法

直接运行此目录下的BuildProto.bat编译proto文件，这个过程会执行如下动作

1. 检查是否安装Python3
2. 调用proto.exe编译proto文件
3. 在编译后的.pb.cc文件中加入自定义代码
4. 将编译后的.pb.h和.pb.cc拷贝到源码目标目录

编译protobuf源代码指导方法

protobuf源码编译

---

这个目录用来下载和编译protobuf源码生成protoc.exe,lib

所需环境

• 需要安装git cmake 并配置好各自环境变量 并支持nmake编译代码

改变protobuf版本号

set “PROTOBUF_VESION=v3.12.4” 改变3.12.4这个数字就可以编译对应的protobuf版本

编译方法

直接运行此目录下的down_and_build_protobuf.bat之后会自动从github下载你配置的protobuf版本源码并编译，这个过程会执行如下动作

1. git clone protobuf源码 gmock源码 gtest源码
2. 用cmake加nmake编译源码
3. 将生成的lib,exe,include 拷贝到相应的目标目录
