准备

1.tolua\_runtime：[https://github.com/topameng/tolua\_runtime][https_github.com_topameng_tolua_runtime]

2.pbc：[https://github.com/cloudwu/pbc][https_github.com_cloudwu_pbc]

3.msys2：本人使用的事配置好的msys2，[https://pan.baidu.com/s/1c2JzvDQ][https_pan.baidu.com_s_1c2JzvDQ]

4.protoc和bat处理生成.pb文件

1.安装msys2

将3解压，拷贝到C盘，将C:\\msys64\\mingw64\\bin或者C:\\msys64\\mingw32\\bin加入到环境变量即可

2.添加pbc

将2全部copy到1的根目录，修改build\_win64.sh如下，参考自[https://blog.csdn.net/kudoran/article/details/72650594][https_blog.csdn.net_kudoran_article_details_72650594]

#!/bin/bash
    # 64 Bit Version
    mkdir -p window/x86_64
    
    cd luajit-2.1
    mingw32-make clean
    
    mingw32-make BUILDMODE=static CC="gcc -m64 -O2" XCFLAGS=-DLUAJIT_ENABLE_GC64
    cp src/libluajit.a ../window/x86_64/libluajit.a
    mingw32-make clean
    
    cd ..
    
    cd pbc
    mingw32-make BUILDMODE=static CC="gcc -m64 -O2" XCFLAGS=-DLUAJIT_ENABLE_GC64
    cp build/libpbc.a ../window/x86_64/libpbc.a
    mingw32-make clean
    
    cd ..
    
    gcc -m64 -O2 -std=gnu99 -shared \
     tolua.c \
     int64.c \
     uint64.c \
     pb.c \
     lpeg.c \
     struct.c \
     cjson/strbuf.c \
     cjson/lua_cjson.c \
     cjson/fpconv.c \
     luasocket/auxiliar.c \
     luasocket/buffer.c \
     luasocket/except.c \
     luasocket/inet.c \
     luasocket/io.c \
     luasocket/luasocket.c \
     luasocket/mime.c \
     luasocket/options.c \
     luasocket/select.c \
     luasocket/tcp.c \
     luasocket/timeout.c \
     luasocket/udp.c \
     luasocket/wsocket.c \
     pbc/binding/lua/pbc-lua.c \
     -o Plugins/x86_64/tolua.dll \
     -I./ \
     -Iluajit-2.1/src \
     -Iluasocket \
     -Ipbc \
     -Ipbc/src \
     -lws2_32 \
     -Wl,--whole-archive window/x86_64/libluajit.a window/x86_64/libpbc.a -Wl,--no-whole-archive -static-libgcc -static-libstdc++

执行build\_win64.sh，可以看到tolua\_runtime下的window和Plugins有更新，将对应的dll拷贝到Unity对应的目录下替换即可

3.注册和添加

在LuaDLL里添加protobuf\_c函数

[DllImport(LUADLL, CallingConvention = CallingConvention.Cdecl)]
    public static extern int luaopen_protobuf_c(IntPtr L);

在LuaClient里添加

protected virtual void OpenLibs()
    {
        //luaState.OpenLibs(LuaDLL.luaopen_pb);
        luaState.OpenLibs(LuaDLL.luaopen_struct);
        luaState.OpenLibs(LuaDLL.luaopen_lpeg);
        luaState.OpenLibs(LuaDLL.luaopen_protobuf_c);
    }

在lua文件里require和register .pb文件。注意一定要注册.pb文件

local function LoadPBFile(fileName,mode)
    	local fullPath = GetProtoFullPath(fileName)
    	local file,err = io.open(fullPath,mode)
    	if file == nil then
    		print(err)
    		return nil
    	end
    	local buff = file:read "*a"
    	file:close()
    	return buff
    end
    
    function RegisterProtocol.Register()
    	if PBFileList ~= nil then
    		for i,v in ipairs(PBFileList) do
    			local buff = LoadPBFile(v,"rb")
    			if buff ~= nil then
    				print(buff)
    				GProtobuf.register(buff)
    			else
    				print("Can't find PBFile, name = "..v)
    			end
    		end
    	end
    end

4.使用

编码

function ClientSendMsg.SendNetMsg(msgId, msg)
    	if msg == nil then
    		ClientSendMsg.SendEmptyMsg(msgId)
    	else
    		local body = get_message_by_id(msgId)
    		if body == nil then print("Get Message Failed, msgId = "..tostring(msgId)) return end
    		print("ClientSendMsg.SendNetMsg  msgId = "..msgId.."  body = "..body)
    		GProtobuf.encode(body,msg,ClientSendMsg.SendMsg,msgId)
    	end
    end

解码

function ClientHandleMsg.Handle(msgId,msgData,msgDataLength)
    	local handleFunc = HandleFuncs[msgId]
    	if handleFunc then
    		local body = get_message_by_id(msgId)
    		local msg,err = GProtobuf.decode(body,msgData,msgDataLength)
    		if err ~= nil then
    			print(err)
    		end
    		handleFunc(msg)
    	else
            print("ClientHandleMsg.Handle->msg handle function not found!msgId="..tostring(msgId))
        end
    end

.测试方便，使用编码的数据直接调用解码方法

ClientHandleMsg.Handle(msgId,buffer,bufferLength)

32位（X86）的编译

#!/bin/bash
    # 32 Bit Version
    mkdir -p window/x86
    
    cd luajit-2.1
    mingw32-make clean
    
    mingw32-make BUILDMODE=static CC="gcc -m32 -O2"
    cp src/libluajit.a ../window/x86/libluajit.a
    mingw32-make clean
    
    cd ..
    
    cd pbc
    mingw32-make BUILDMODE=static CC="gcc -m32 -O2"
    cp build/libpbc.a ../window/x86/libpbc.a
    mingw32-make clean
    cd ..
    
    gcc -m32 -O2 -std=gnu99 -shared \
    	int64.c \
    	uint64.c \
    	tolua.c \
    	pb.c \
    	lpeg.c \
    	struct.c \
    	cjson/strbuf.c \
    	cjson/lua_cjson.c \
    	cjson/fpconv.c \
    	luasocket/auxiliar.c \
    	luasocket/buffer.c \
    	luasocket/except.c \
    	luasocket/inet.c \
    	luasocket/io.c \
    	luasocket/luasocket.c \
    	luasocket/mime.c \
    	luasocket/options.c \
    	luasocket/select.c \
    	luasocket/tcp.c \
    	luasocket/timeout.c \
    	luasocket/udp.c \
    	luasocket/wsocket.c \
    	pbc/binding/lua/pbc-lua.c \
    	-o Plugins/x86/tolua.dll \
    	-I./ \
    	-Iluajit-2.1/src \
    	-Icjson \
    	-Iluasocket \
    	-Ipbc \
    	-Ipbc/src \
    	-lws2_32 \
    	-Wl,--whole-archive window/x86/libluajit.a window/x86/libpbc.a -Wl,--no-whole-archive -static-libgcc -static-libstdc++

注意在编译64位和32位时，注意修改下环境变量中msys64工具的顺序
