我正在尝试在汇编语言上编译和链接我的第一个程序。 我试图编译以下代码:
; %include "stud_io.inc"
global _main
section .text
_main:
xor eax, eax
again:
; PRINT "Hello"
; PUTCHAR 10
inc eax
cmp eax, 5
jl again
以下是编译和链接程序的控制台命令:
-bash-3.2$ nasm -f macho main.asm -o main.o && ld -e _main -macosx_version_min 10.8 -arch x86_64 main.o
但结果是:
ld: warning: ignoring file main.o, file was built for i386 which is not the architecture being linked (x86_64): main.o
Undefined symbols for architecture x86_64:
"_main", referenced from:
-u command line option
ld: symbol(s) not found for architecture x86_64
我认为编译x86_64的main.asm文件是必要的。 如何正确地为我的系统编译程序?
