Kann Alsa nicht mehr kompilieren

[Abitor]

Habe die Alsa Treiber zuvor schon ein paar mal ohne jegliche Probleme kompiliert,aber wenn ich jetzt "emerge media-sound/alsa-driver" mache,dann kommt folgendes dabei heraus:

Hier meine USE und CFLAGS(wobei es mit diesen Einstellungen vorher ja ohne Probleme ging)

USE="X gtk alsa kde nls mmx sse sse2 perl truetype cups avi mpeg quicktime java opengl qt tcltk jpeg png tiff gif"

CFLAGS="-march=pentium4 -O2 -pipe -fomit-frame-pointer -mmmx -msse -msse2"

Ich hoffe ihr habt eine Idee woran das liegen könnte und wie man das Problem beseitigen kann,danke.

ich hab das Problem gehabt, als der link unter /usr/src/linux nicht mehr auf die Sourcen gezeigt hat, die zu dem Kernel gehörten der aktuell läuft.
Es lieft ein 2.4.19 und durch updaten des systemes wurden die kernel-sourcen auf 2.4.20 geupdate.

THX für den Tipp,hab den kernel neu kompiliert und nun geht es wieder.
