Troubleshooting

lua_open returns null using luaJIT

• Stackoverflow - lua_open returns null using luaJIT
• Installation

If you're building a 64 bit application on OSX which links directly or indirectly against LuaJIT, you need to link your main executable with these flags:

-pagezero_size 10000 -image_base 100000000

중요한 점은 위 플래그는 Shared Library 가 아닌, EXE 링크 플래그로 전달해야 한다.
