I have some problems compiling alsa-drivers-1.0.7 on sparc32. I get errors
asm/asm_offsets.h: Datei oder Verzeichnis nicht gefunden
I have kernel-headers-2.4.27-1 installed (and kernel-image-2.4.27-1 is
What can I do about this? The asm_offsets.h file does only seem to exist in:
# find .. -name asm_offsets.h
Is this a kernel-headers package problem?

That patch is incomplete: alsa-driver/acinclude.m4 needs to be modified and
aclocal and autoconf must be run afterwards, so that the configure option
is usable. Just take AMD7930 as example and make a simple copy and modify.

Maybe you should remove that file. It does not work with alsa-source package
in Debian an upstream is at 1.0.7 to which that patch does not apply.
I'd really like to test this but first I have to fix the problem above. Maybe
someone can give me a hint...
I use the configure options
--with-sequencer=yes --with-oss=yes --with-cards=sun-amd7930,sun-dbri
