I tried to compile the below code using the "fasm" command, but it gives the error shown in the heading.

Code:


BITS 32

%include        'training.s' 

global main
extern  exit    

; ===============================================
section .text

    ; The program begins here:

    call    read_hex
    mov     ecx,eax
    call    read_hex
    sub     eax,ecx
    jnz     l1

    mov     eax,1
    call    print_eax
    jmp     l2

l1:
    mov     eax,0
    call    print_eax
l2:

    ; Exit the process:
        push    0
        call    exit

What you appear to have there is NASM code (or MASM, or whatever) and not FASM code.

The fasm equivalent of "bits 32" is "code32".

But even after changing that you will discover that there are a bunch of other problems further on.

Good luck with your coursework.

Hi yes , this example is for "yasm" I guess. Downloaded the correct one now. Thanks a lot
