PROBLEM: OSS/MAD16 not available to compilation of kernel

PROBLEM: OSS/MAD16 not available to compilation of kernel

[erlk ozlr]

Hi,
I'm using linux 2.6.17 and I want to compile the mad16 driver but "at
least" CONFIG_SOUND_MAD16 is not present in "<source
root>/sound/oss/Kconfig" which makes it unchoosable in the `make
<something>config`, but there is still presence in the
"/sound/oss/Makefile".
I said "at least" because adding "CONFIG_SOUND_MAD16=m" in the
".config" file doesn't help : when I do `make modules_prepare`, it
removes the line, and I add it again then do `make modules
SUBDIRS=sound/oss` (well, I don't want to compile the whole kernel and
modules, I only lack mad16 ; I'm telling it because it perhaps has
consequences), it produces warnings (I don't know if it's the same
problem) but I have a mad16.ko.
Here is some log (maybe it isn't interesting) : """
  Building modules, stage 2.
  MODPOST
WARNING: sound/oss/cs4232.o - Section mismatch: reference to
.init.text: from .text between 'cs4232_pnp_probe' (at offset 0x5d) and
'unload_cs4232'
WARNING: sound/oss/mad16.o - Section mismatch: reference to
.init.data:mpu_io from .text after 'init_module' (at offset 0x15b)
"""
then follows many lines like this last one (the offset and the
"reference to" do change)

I can't tell you yet if the mad16.ko works because I'm lacking some
cross-kernel-compilation knowledge too : it says "invalid module
format", I checked the gcc version, building against the same x.y.z
version kernel source (please notice the subtly silent newbie-question
:-) ), and both computers are i386 (as says `file mad16.ko`).

ah, last thing, the report-bug-howto tells me to give keywords, so
here some :-) : modules, sound, obsolete, oss, mad16

thanks if you can fix or explain it :-)

OSS is being stripped down to remove all the hardware that has been
supported for some years by ALSA as part of the migration to ALSA that
has been going on over time. The ALSA Opti 82C9xx chipset driver should
act as a replacement for MAD16.
