Thema: Probleme mit der IDT

[MrTom3715]

Hallo,
ich bin gerade dabei die IDT zu programmieren, habe aber ein Problem.
Wenn ich kompilieren will meldet mir das Terminal, dass bei

Code: [Auswählen]

static uint64_t idt[IDT_ENTRIES];IDT_ENTRIES nicht deklariert ist.

Hier meine ganze idt.c:

Was habe ich falsch gemacht?

Danke für eure Antworten.

Hä, hast du das Makro IDT_ENTRIES eig definiert mit #define IDT_ENTRIES irgndeinint?

Was habe ich falsch gemacht?

Du hast Code kopiert ohne ihn zu verstehen.

Das wohl auch
