为什么nasm中的构建汇编源在win 7中不起作用？ [英] Why the build assembly source in nasm don't work in win 7?

问题描述

我的朋友我构建了一个汇编源：

my friend i build a assembly source:

section	.text
    global _start   ;must be declared for linker (ld)
_start:	            ;tells linker entry point
    mov	edx,len     ;message length
    mov	ecx,msg     ;message to write
    mov	ebx,1       ;file descriptor (stdout)
    mov	eax,4       ;system call number (sys_write)
    int	0x80        ;call kernel
	
    mov	eax,1       ;system call number (sys_exit)
    int	0x80        ;call kernel

section	.data
msg db 'Hello, world!', 0xa  ;our dear string
len equ $ - msg     ;length of our dear string

用于构建我使用此命令行：

nasm -f bin index.asm -o hhh.com

i从此链接读取：

doc nasm
我点击它时建立的
：它有错误：请看图片：

可以帮助我吗？

谢谢



< b>我尝试了什么：



i用命令行测试但是内置文件无法运行。

what should i do?

推荐答案

- msg;长度我们亲爱的字符串

- msg ;length of our dear string

用于构建我使用此命令行：

nasm -f bin index.asm -o hhh.com

i从以下链接读取：

doc nasm
当我点击它时它构建：它有错误：请看图像：

你不能直接从汇编程序创建一个.com程序（包括源代码的事实）不支持它）。输出应该有.exe扩展名。

You cannot create a .com program directly from the assembler (including the fact that the source does not support it). The output should have a .exe extension.

我有一个愚蠢的错误!!

i完成回答我的朋友后认为我得出结论 int 0x80 不是在windows中，它应该是用于linux。

Richard MacCutchan非常感谢。

亲切的你的堆栈程序员

i had a silly wrong!!
i completed answer my friend after thinking i concluded that int 0x80 is not in windows, it should be for linux.
Richard MacCutchan thanks very much.
