動態庫在Mac上擴展名爲.dylib而不是ELF/* NIX .so。 – Will 2013-04-10 10:35:20

此外，這個問題可能會爲您提供一些有用的信息：http://stackoverflow.com/q/1212477/1353098 – Will 2013-04-10 10:36:59

變化-shared到-bundle -undefined dynamic_lookup。
luaL_register不是Lua 5.2的一部分，除非您與-DLUA_COMPAT_MODULE打開兼容性。或使用此

#define luaL_register(L,n,l) (luaL_openlib(L,(n),(l),0))

當創建一個共享庫，做不鏈接.so與Lua的庫。
