我写了这段代码:
global _main
extern _printf
section .text
_main:
push message
call _printf
add esp, 4
ret
message:
db 'Hello, World', 10, 0
并尝试从cmd运行它。看起来像这样:
C:\Users\user\AppData\Local\bin\NASM>nasm helloworld.asm -f win64 -o helloworld.obj
C:\Users\user\AppData\Local\bin\NASM>gcc helloworld.obj -m64 -o helloworld.exe
helloworld.obj: file not recognized: File format not recognized
collect2: ld returned 1 exit status
我在Google中搜索了此错误,但与我无关。如您所见,我正在使用Windows(10)。有人知道如何解决这个问题吗?谢谢。
当我运行gcc -v时,我得到了:

答案 0 :(得分:2)
从您的gcc -v
输出来看,您似乎正在使用mingw-32。
您需要获取mingw-w64。
此外,Windows的64位代码中的功能看起来完全不同。重写您的代码,如下所示:
; ----------------------------------------------------------------------------------------
; This is a Win64 console program that writes "Hello" on one line and then exits. It
; uses puts from the C library. To assemble and run:
;
; nasm -fwin64 hello.asm && gcc hello.obj && a
; ----------------------------------------------------------------------------------------
global main
extern puts
section .text
main:
sub rsp, 28h ; Reserve the shadow space and align stack
mov rcx, message ; First argument is address of message
call puts ; puts(message)
add rsp, 28h ; Remove shadow space
ret
message:
db 'Hello', 0 ; C strings need a zero byte at the end
