Lua Protobuf

作者：追风剑情发布于：2019-1-30 14:27 分类：Unity3d

在使用protoc-gen-lua前，先确保电脑上已经安装了Python2.x以及Protobuf

一、下载protoc-gen-lua

https://github.com/sean-lin/protoc-gen-lua

二、写两个批处理文件

python %~dp0protoc-gen-lua

cd ./example  
for %%i in (*.proto) do (  
echo %%i  
protoc --plugin=protoc-gen-lua="..\plugin\protoc-gen-lua.bat" --lua_out=.  %%i  
  
)
echo end  
pause

二、运行protoc.bat

此时已经通过person.proto生成了一个person_pb.lua文件

问题1：如果未生成person_pb.lua文件，但cmd中输出是正确的，可以修改下Plugin\protoc-gen-lua文件

问题2：下载的person.proto没声明版本号可能会导致编译报错,需要自己加上。

下面贴出生成的person_pb.lua文件内容

Person.RegisterExtension(PHONE_PHONES_FIELD)

三、gcc编译pb.c为对应平台的库文件

windows平台,编译成pb.dll

1、下载min-gw工具

https://sourceforge.net/projects/mingw/files/

2、安装min-gw
