I suppose we should do a FAQ entry for this kind of problem, once we
understand what to say.
These "Undefined symbol" messages usually point to a missing module in
the list of object files to be included in the kernel. That in turn
usually points to a missing entry in the configuration file.
Let's see... the first thing to do would be to search for one of the
names in the kernel sources:
$ find /sys -follow -name "*.c" | xargs grep gunsintr
$ find /sys -follow -name "*.c" | xargs grep opldriver
/sys/i386/isa/sound/soundcard.c:struct isa_driver opldriver = {sndprobe, sndattach, "opl"};
/sys/i386/isa/sound/soundcard.c: if (driver == &opldriver)
Hmmm. Is gunsintr really the name? Anyway, we've established that we
you probably don't have soundcard.o in your kernel build list. Next,
let's see what module requires it:
$ grep soundcard.c /sys/i386/conf/files.i386
i386/isa/sound/soundcard.c optional snd device-driver
The 'device-driver' at the end of the line suggests that you should be
looking for a 'controller' entry in the config file entry. Look for
one in LINT like this:
$ grep "controller.*snd" /sys/i386/conf/LINT
controller snd0
So, try adding the line 'controller snd0' to your config file and try
again.
