Question

我是汇编语言的新手。现在我正在编写我的'hello，world'.s程序。

代码来自Richard Blum的“Professional Assembly Language”一书：

        ;; #cpuid.s Sample program to extract the processor Vendor ID

.section .data,
output:
    .ascii "The processor vendor is 'xxxxxxxxxx'\n"

.section .bbs,

.section .text,
.globl _main
_main:  
    movl $0, %eax
    ;; cpuid
    ;; movl $output, %edi
    ;; movl %ebx, 28(%edi)
    ;; movl %edx, 32(%edi)
    ;; movl %ecx, 36(%edi)
    ;; movl $4, %eax
    ;; movl $1, %ebx
    ;; movl $output, %ecx
    ;; movl $output, %ecx
    ;; movl $42, %edx
    ;; int $0x80
    ;; movl $1, %eax
    ;; movl $0, %ebx
    ;; int $0x80

本书指示使用'as'和'ld'编译，但我没有使用它们。那我用gcc： gcc -o cpuid cpuid.s，但仍然得到错误：

****:asm $ls
cpuid.s
****:asm $gcc -o cpuid cpuid.s

我的环境是： mac os 10.7,64bit

你能帮我编译一下这段代码吗？
