问题描述
我试图编译和链接汇编我的第一个程序。
我尝试编译以下code:
I am trying to compile and link my first program on Assembler.I try to compile the following code:
; %include "stud_io.inc"
global _main
section .text
_main:
xor eax, eax
again:
; PRINT "Hello"
; PUTCHAR 10
inc eax
cmp eax, 5
jl again
下面的编译和链接程序的控制台命令:
Below the console command for compiling and linking a program:
-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
我认为它需要编译的x86_64的文件main.asm中..
如何编译我的系统程序是否正确?
I think its necessary to compile the main.asm file for x86_64..How to compile programs for my system properly?
推荐答案
我会建议先更新您的。
在此之后,尝试运行这样的:
After that, try running this:
nasm -f macho64 main.asm -o main.o && ld -e _main -macosx_version_min 10.8 -arch x86_64 main.o -lSystem
请注意,新的命令添加上述JasonD的建议( macho64
),而且还增加了 -lSystem
来的 LD
命令从抛出以下错误停止LD:
Notice that the new command adds JasonD's suggestion above (macho64
), but also adds the -lSystem
to the ld
command to stop ld from throwing following error:
ld: dynamic main executables must link with libSystem.dylib for architecture x86_64
