lua 5.2 C api中的语法更改

但仅适用于lua 5.1,在5.2上执行此操作的步骤是什么？

这是我正在使用的代码

#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);
    if (error) {
      fprintf(stderr,"%s",lua_tostring(L,-1));
      lua_pop(L,1);  /* pop error message from the stack */
    }
  }
  lua_close(L);
  return 0;
}

用gcc test01.c -I /usr/include / lua5.2 -L /usr/lib / x86_64-linux-gnu -llua5.2编译后出现以下错误：

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':

先感谢您.
