MacBook Pro配置彙編開發環境

配置開發環境

方法一:

• 打開命令行,輸入指令which nasm查看nasm的安裝路徑，Mac系統默認安裝了nasm.通常默認返回的路徑是/usr/bin/nasm
• 接着輸入指令alias nasm=/usr/bin/nasm
• 輸入指令nasm -v若是配置成功的話，就會返回nasm的版本號NASM version 2.14.02 compiled on Dec 27 2018，
  若是配置失敗就會返回:macs-MacBook-Pro:~ mac$ nasm nasm: error: unable to find utility "nasm", not a developer tool or in PATH

方法二:

若是第一種方法配置失敗了，那麼考慮第二種方法。重裝nasm

• brew reinstall nasm

測試helloworld代碼

• 命令行輸入指令vim helloworld.asm，新建helloworld文件，文件類型爲asm

helloworld彙編代碼

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

而後輸入以下指令

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

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

./helloworld

運行結果

Hello World!
