Possible Issues and Solutions

undefined reference to `__stack_chk_fail_local'

When compiling, GCC may give the error gdt.cpp:(.text+0xa2): undefined reference to `__stack_chk_fail_local'. If this happens, create function __stack_chk_fail_local() inside the file GCC says it can't find it in. Keep in mind that there can only be one of these functions, so if it's already implemented somewhere else you will have to move it. As of writing this, the __stack_chk_fail_local function is already written in myos/src/gdt.cpp. If it is ever moved in this repository, you can find it by searching for __stack_chk_fail_local in github's "search in this repository" feature.

Example of implemented function:

uint32_t __stack_chk_fail_local(){
    return 0;
}
