Linking error in sounddrivers.o (2.4.20)

Linking error in sounddrivers.o (2.4.20)

[Olivier Dragon]

Greetings,

In the 2.4.20 kernel I have encountered a linking error happening in
sounddrivers.o. It happens with the following config file when doing
"make bzImage". It first happened with a ck6 patched kernel but I have
verified on two different computers (laptop running knoppix 3.2 and
desktop running Debian unstable) that it also happens in the unpatched
vanilla kernel.

http://dragon.homelinux.org/linux-2.4.20-ck6-config

Here is the few last lines before the error occurs, during a
"make bzImage":

Does it still happen with 2.4.21-rc2? Also, could you please send me
in private the .config? I get a 504 gateway error when trying to wget
it.

That's a fairly experimental kernel for compiling kernels. You might
want to stick with 2.95 for the time being.

Sorry about that. It's on my home machine and I turn it off at night to
save power (and money). It should be online all day.

Actually now I get a different error, and it happens before the final
linkage step at which I used to get an error. But I think it might be an
error with GCC. There's a little blurb about submitting a bug report.

I've compiled quite a few kernels with a 3.2.x gcc and I've never run
into problems before. I'll change that to 2.95 and see what happens.

I've attached my .config to a private email following this one.

Thanks for your input,

Ok, I've compiled 2.4.21-rc2 (make dep; make bzImage) with 2.95 and I
got rid of the compilation error (most likely gcc bug) but I still get
the same linking error as previously mentioned. See below:

The linking error happens because you have 

CONFIG_SOUND_TRIDENT=y
and 
CONFIG_INPUT_PCIGAME=m 

trident.c will call pcigame_attach(), which is either defined or a
nop, depending on whether CONFIG_INPUT_PCIGAME is defined or not. In
your .config it's defined, but as a module. So the call to
pcigame_attach() is trident is defined. But trident is built in, so
when the linker tries to link everything together, it fails because it
cannot find the code for pcigame_attach. It can't find it, since it's
compiled as a module, and thus not linked into the bzImage. 

As a quick fix, you can either make trident a module, or make pcigame
built in, or remove pcigame, if you don't have a joystick
attached. This fairly ugly untested patch against 2.4.21-rc2 should
enforce the dependencies between trident and pcigame.
