当我尝试在 Windows 上编译一个简单的汇编程序时，我遇到了奇怪的错误。这些错误看起来好像汇编器不知道我使用的函数是什么，并且出于某种原因也将 Haskell 带入其中。
这是我尝试编译时遇到的错误：

这是 NASM 代码：
;
; file: first.asm
; First assembly program. This program asks for two integers as
; input and prints out their sum.
;
; To create executable:
; Using djgpp:
; nasm -f coff -d COFF_TYPE first.asm
; gcc -o first first.o driver.c asm_io.o
;
; Using Borland C/C++
; nasm -f obj -d OBJ_TYPE first.asm
; bcc32 first.obj driver.c asm_io.obj
%include "asm_io.inc"
