Cannot link with Lua library on Linux

Question

I've compiled Lua 5.2 on Debian x86-64 with make posix, and am trying to compile the following with the command gcc -ldl -llua main.c

#include "lua.h"
#include "lauxlib.h"
#include "lualib.h"
int main() {  
  lua_State *L = luaL_newstate(); 
  luaL_openlibs(L);  
  dofile("test.lua");   
  return 0;
}

and get unresolved references to the lua functions

Answer 1

Assuming your error is

undefined reference to `dofile'

then your problem is that dofile is a lua function and not a C one.

You probably want luaL_dofile(L, "test.lua").
