Write your own Operating System 5: Interrupts

[tiagomendes7]

I am trying to implement the YouTube series "Writing your own OS".

You can find my code at "https://github.com/tiagomendes7/Build_Your_Own_OS/tree/main".

Unfortunately i came across this error and i don't know how to solve it. I believe it has to do with the file "interruptstubs.s" and the code in the line 19 and line 20:

global _ZN16InterruptManager26HandleInterruptRequest\num\()Ev
_ZN16InterruptManager26HandleInterruptRequest\num\()Ev:

Below you can find the output of the command "make mykernel.iso":

UPDATE: It is working now. All that was needed was to remove the definition of HandleInterruptRequest0x00() and HandleInterruptRequest0x01() from interrupts.cpp file.
