Dock när jag försöker länka in libc och libnosys så klagar länkaren på att vissa objektfiler saknas, men dessa finns i libnosys. libnosys är tillagt på komandoraden så den ska länkas med. Även listfilerna indikerar att biblioteket är inläst.
Det behövs säkert mer info än detta för att lösa problemet, men jag får försöka svara på eventuella frågor vart efter...
Alla funktioner finns inte med här men tex isatty borde ju länkas in tycker man.
Här är lite felutskrifter:
