Interrupts.s gives various errors

[Mehmetdev1]

Hello. The interrupt.S file gives various errors, what is the solution, I am posting the code and screenshot:

Interrupt.s Code:

Code: Select all

.set IRQ_BASE, 0x20
 
.section .text

.extern _ZN16InterruptManager15handleInterruptEhj

.global _ZN16InterruptManager22IgnoreInterruptRequestEv






.macro HandleException num
.global _ZN16InterruptManager16HandleException\num\()Ev
_ZN16InterruptManager16HandleException\num\()Ev:
    movb $\num, (interruptNumber)
    jmp int_bottom
.endm

.macro HandleInterruptRequest num
.global _ZN16InterruptManager26HandleInterruptRequest\num\()Ev
_ZN16InterruptManager26HandleInterruptRequest\num\()Ev:
             movb $\num + IRQ_BASE, (interruptNumber)
             jmp int_bottom
        .endm     



HandleInterruptRequest 0x00
HandleInterruptRequest 0x01




int_bottom:

   pusha
   pushl %ds
   pushl %es
   pushl %fs
   pushl %gs
   
   pushl %esp
   push (interruptNumber)
   call _ZN16InterruptManager15handleInterruptEhj
   # addl $5, %esp
   movl %eax, %esp
   
   popl %gs
   popl %fs
   popl %es
   popl %ds
   popa
   
   
_ZN16InterruptManager22IgnoreInterruptRequestEv:
   
   
   iret
   
   
.data
    .interruptnumber: .byte 0

Again, the error messages are telling you exactly what the problem is. Time to learn x86 assembler programming, and the meaning of the various directives and defines.

"interruptnumber" is not declared as a global (via the ".global" directive), and is inconsistently spelled (once as ".interruptnumber", once as "interruptNumber").
