我正在学习nasm，并试图从gcc做一个消息框。我的代码是这样的：

%include "win32n.inc"

extern MessageBoxA
import MessageBoxA user32.dll
extern ExitProcess
import ExitProcess kernel32.dll

section .data USER32

title db "Hello", 0
message db "Hello World",0

section .text
global main

    main:
    push dword MB_OK
    push dword title
    push dword message
    push dword 0
    call [MessageBoxA]

    push dword 0
    call [ExitProcess]

然后我得到这个错误：
