MacBook Pro配置汇编开发环境

Posted 2020-08-17 芷恬

配置开发环境

方法一:

• 打开命令行,输入指令which nasm查看nasm的安装路径，Mac系统默认安装了nasm.一般默认返回的路径是/usr/bin/nasm
• 接着输入指令alias nasm=/usr/bin/nasm
• 输入指令nasm -v如果配置成功的话，就会返回nasm的版本号NASM version 2.14.02 compiled on Dec 27 2018，
  如果配置失败就会返回:macs-MacBook-Pro:~ mac$ nasm nasm: error: unable to find utility "nasm", not a developer tool or in PATH

方法二:

如果第一种方法配置失败了，那么考虑第二种方法。重装nasm

• brew reinstall nasm

测试helloworld代码

• 命令行输入指令vim helloworld.asm，新建helloworld文件，文件类型为asm

helloworld汇编代码

SECTION .data

msg: db "Hello World!", 0x0a
len: equ $-msg

SECTION .text
global _main

kernel:
    syscall
    ret

_main:
    mov rax,0x2000004
    mov rdi,1
    mov rsi,msg
    mov rdx,len
    call kernel

    mov rax,0x2000001
    mov rdi,0
    call kernel

然后输入如下指令

nasm -f macho64 -o helloworld.o helloworld.asm

ld -o helloworld -e _main helloworld.o -macosx_version_min 10.13 -lSystem

./helloworld

运行结果

Hello World!
