gcc error on trying to compile lua file

I am trying to create executable from lua file using following method:

I use bintocee utility (from: http://lua-users.org/wiki/BinToCee) to convert myfile.lua to code.c . I then use following main.c (from: Creating standalone Lua executables)

#include <stdlib.h>
#include <stdio.h>

#include "lua.h"
#include "lauxlib.h"
#include "lualib.h"

int main(int argc, char *argv[]) {
  int i;
  lua_State *L = luaL_newstate();
  luaL_openlibs(L);
  lua_newtable(L);
  for (i = 0; i < argc; i++) {
    lua_pushnumber(L, i);
    lua_pushstring(L, argv[i]);
    lua_rawset(L, -3);
  }
  lua_setglobal(L, "arg");
#include "code.c" 
  lua_close(L);
  return 0;
}

Then I give command: 

gcc main.c -o myfile.exe

However, I get following error: 

/tmp/ccyIOC0O.o: In function `main':
main.c:(.text+0x21): undefined reference to `luaL_newstate'
main.c:(.text+0x2f): undefined reference to `luaL_openlibs'

main.c:(.text+0xea): undefined reference to `lua_pcall'
main.c:(.text+0xf8): undefined reference to `lua_close'
collect2: error: ld returned 1 exit status

I am working on Linux Debian Stable (updated). Where is the problem and how can this be solved? Thanks for your help.

Since you installed liblua-5.1-dev, I assume you are on Debian or a derivative. There, you have to link with -llua5.1, like this:

gcc -O2 -Wall -I/usr/include/lua5.1 main.c -llua5.1
