[linux] Fout bij compileren kernl 2.6.8

[Bram Mertens]

Hey

Gisteren heb ik voor het eerst een eigen kernel gecompileerd op basis 
van de config van m'n huidige kernel. Ik moet de kernel zelf nog 
installeren (heb make-kpkg gebruikt om een deb te bouwen) maar eerst wil 
ik een vraag stellen of m'n eerste poging.

Voor m'n eerste poging heb ik eerst de config van m'n huidige kernel uit 
/boot/ naar /usr/src/kernel-source-2.6.8/.config gekopieerd.  Daarna heb 
ik make oldconfig gevolgd door make menuconfig gebruikt om een aantal 
zaken uit de kernel te smijten.

Blijkbaar ben ik daar als "newbie" net iets te drastisch in geweest want
fakeroot make-kpkg --append-to-version=.050614

gaf vrij snel volgende fout:
   CC      arch/i386/kernel/cpu/intel.o
In file included from arch/i386/kernel/cpu/intel.c:19:

Zoals gezegd moet ik de kernel zelf nog testen maar het compileren lijkt 
verder zonder problemen verlopen.

Moet ik dergelijke fouten/waarschuwingen ergens melden? Of is dit 
normaal gedrag?

Alvast bedankt
