参照这两篇教程编译tolua

从mingw的shell执行build_xx.sh时报错。

这个是因为mingw找不到tolua相关的路径，不知道是教程少写了步骤，还是我对教程的理解有误，反正最后自己瞎捣鼓出来了。

解决方法：

先打开cmd，cd到mingw安装路径

-- cmd:
> cd xxx/msys64

cmd启动mingw的shell，以64位为例

-- cmd:
> mingw64_shell.bat

mingw的shell里cd到tolua源码路径

-- shell:
$ cd x:/xxx/tolua_runtime-1.0.8.584

mingw的shell里执行对应平台的build，这里注意shell里执行文件时和cmd里的命令不一样，需要文件前加上"./"

-- shell:
$ ./build_win64.sh

编译成功，生成的dll在 tolua源码路径/Plugins/对应平台/ 下。

$ ./build_win64.sh
