Syntax Change in lua 5.2 C api

I tried to compile the example provided in the book Programming in Lua

But only works for lua 5.1, what are the steps for doing this on 5.2?

This is the code I am using

#include <stdio.h>
#include <string.h>
#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>

int main (void) {
  char buff[256];
  int error;
  lua_State *L = lua_open();   /* opens Lua */
  luaL_openlibs(L);  
  while (fgets(buff, sizeof(buff), stdin) != NULL) {
    error = luaL_loadbuffer(L, buff, strlen(buff), "line") ||
      lua_pcall(L, 0, 0, 0);
    if (error) {
      fprintf(stderr, "%s", lua_tostring(L, -1));
      lua_pop(L, 1);  /* pop error message from the stack */
    }
  }
  lua_close(L);
  return 0;
}

      

        
        
        
      

    

After compiling with, gcc test01.c -I/usr/include/lua5.2 -L/usr/lib/x86_64-linux-gnu -llua5.2

I get the following errors:

test01.c: In function ‘main’:
test01.c:10:18: warning: initialization makes pointer from integer without a cas
t [enabled by default]                                                         
   lua_State *L = lua_open();   /* opens Lua */
                  ^
/tmp/ccyPRlV3.o: In function `main':

collect2: error: ld returned 1 exit status

      

        
        
        
      

    

Thanks in advance.
