我试图在我的Mac运行在终端下面的代码:GCC运行汇编程序mac?
.section, .data
format_string:
.asciz "My favorite number is %d!"
number:
.long 786
.section, .text
.globl main
main:
pushl number
pushl $format_string
call printf
addl $8, %esp
pushl $0
call exit
此代码是在一个名为favorite.s
文件我用命令“GCC favorite.s -m32”和我看到以下消息:
Undefined symbols for architecture i386:
"_main", referenced from:
start in crt1.10.6.o
"exit", referenced from:
main in ccUKdD8O.o
"printf", referenced from:
main in ccUKdD8O.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
我在做什么错在这里?谢谢。
添加之后,我现在正在输出“Illegal instruction:4”的输出:/ – zProgrammer 2013-02-13 06:54:48
声音在某处出现错字。你能显示你的更新代码吗? – 2013-02-13 06:58:25
我想一个简单的程序,它产生同样的消息: .section伪,的.text .globl _main _main: #传递一个参数退出。 pushl $ 27 call _exit – zProgrammer 2013-02-13 07:00:52
