记得要在属性/连接器/输入/模块定义文件中输入def的文件名称如lfs.def,以及lua的lib(或dll?测试用的lib)
上面的代码中,最后export出去的函数是luaopen_mylib,一定要注意:函数名luaopen_mylib表明了最后输出的dll名称必须为mylib.dll,而且大小写要一致,否则lua无论如何都找不到luaopen_mylib函数的。
上面函数是cpp的,如果是c的最后一个函数格式会有变int luaopen_lfs (lua_State *L) {。。。具体参照luafilesystem的代码
lfs.def内容:
LIBRARY lfs.dll
VERSION 1.6
EXPORTS
luaopen_lfs
