Why does LD doesn't link my NASM object file?

I wrote a small code in NASM:

section .data
    msg db 'Hello', 0
section .text
global main
main:
    mov eax, 4
    mov ebx, 1
    mov ecx, msg
    mov edx, 5
    int 80h
    mov eax, 1
    mov ebx, 0
    int 80h

Then I compiled it with NASM and LD: nasm -f win32 main.asm ld main.asm -o main.obj But it said this: C:\Users\Bogdan\AppData\Local\bin\NASM>ld: i386 architecture of input file 'main .obj' is incompatible with i386:x86-64 I also tried this: C:\Users\Bogdan\AppData\Local\bin\NASM>ld -m i386pe -s -o main.exe main.obj Using this, an EXE file makes, but it is not running at all. What is causing this problem, and how can I fix it?

Using `-m i386pe` would be correct. but your code using `int 80h` is for Linux 32-bit system calls and not for Windows so it will fail when run. – Michael Petch Jul 10 '23 at 08:37
Can you, please, tell me, what instruction do I have to use to call NASM syscall for windows? – Cool_AsmProgrammer_228 Jul 10 '23 at 12:20
