I'm trying to port my game engine from windows to linux, and I'm a bit new at linux programming so please bear with me. In windows I have all my modules in DLLs which I load at runtime via LUA functions. I'm trying to do the same with linux. So I have: "core" loads libgfx.so via dlload "libgfx.so" - compiled with -fPIC - linked with -llua -llualib - In C++, with lua headers as follows:

extern "C" {
#include "lua.h"
#include "lualib.h"
}  

Problem is, at runtime when I call dlload I get the following error:

./core: relocation error: /usr/local/lib/libgfx.so: undefined symbol: lua_pushstring 

Any idea why this would happen? Is there another forum where I would get a better answer to this question? [edited by - ParadigmShift on October 26, 2003 2:37:12 PM]

try dlopen()ing the lua library as well, with the flags RTLD_GLOBAL and RTLD_NOW.

then open your library

Sweet, that did it! Thanks!
