Need to fix bugs causes compiling error. One is related to Open Sound System Emuration. The other is caused by patches.

[Takashi Sakamoto]

This source cannot be used with module-assistant
because this source includes some bugs causes compiling error.
You can see this error in the process below.

1. $ sudo apt-get install module-assistant;
2. $ sudo module-assistant prepare;
3. $ sudo module-assistant update;
4. $ sudo module-assistant auto-install alsa;
5. failed.

The bugs in this source are classified two parts below.

1. Open Sound System Emulation issue
2. troubles by modification when creating package

1. Open Sound System Emulation issue
Ubuntu's generic kernel has no options related to Open Sound System.
You can see the kernel configuration in /boot/config-2.6.38-11-generic
if you use 2.6.38-11-generic kernel.

$ cat /boot/config-2.6.38-11-generic;
# CONFIG_SOUND_OSS_CORE is not set
# CONFIG_SND_MIXER_OSS is not set
# CONFIG_SND_PCM_OSS is not set
# CONFIG_SND_SEQUENCER_OSS is not set

So Open Sound System Emuration should be disabled in ALSA, too.
But as a default, this source enable it.

As a result, even if we are success to compile the source and install them,
then modprobe reject to call them with errors.

For example:
$ dmesg;
[ 3.015889] snd: Unknown symbol unregister_sound_special (err 0)
[ 3.016859] snd: Unknown symbol register_sound_special_device (err 0)
[ 3.019419] snd_timer: Unknown symbol snd_info_register (err 0)
[ 3.019473] snd_timer: Unknown symbol snd_info_create_module_entry (err 0)
[ 3.019556] snd_timer: Unknown symbol snd_info_free_entry (err 0)
[ 3.019697] snd_timer: Unknown symbol __snd_printk (err 0)
[ 3.019750] snd_timer: Unknown symbol snd_iprintf (err 0)
[ 3.019827] snd_timer: Unknown symbol snd_ecards_limit (err 0)
[ 3.019908] snd_timer: Unknown symbol snd_oss_info_register (err 0)
[ 3.019961] snd_timer: Unknown symbol snd_unregister_device (err 0)
[ 3.020049] snd_timer: Unknown symbol snd_device_new (err 0)
[ 3.022230] snd_timer: Unknown symbol snd_register_device_for_dev (err 0)

To avoid this, it's good to enable --with-oss=no option in configure script
or put some equivalent codes into configure script.
The latter is good to use this with module-assistant.

2. troubles by modification when creating package
I generated diff between this source and original ALSA source and realized two modification.

2-1. half-finished replacement of macros
In this source, @CONFIG_SND_KERNELSRC@ is rewrited as @CONFIG_SND_KERNELDIR@ but it's half-finished.
Two files still include @CONFIG_SND_KERNELSRC@ and this causes error
because @CONFIG_SND_KERNELSRC@ is not extracted.

Files:
/include/linux/pci_ids_compat.h
/include/linux/i2c_id.h

To avoid this, it's good to modify the lines in these two files of this source.

(I've already reported this but it was expired
Compile error with "@CONFIG_SND_KERNELSRC@/include/linux/pci_ids.h: No such file or directory".
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/778887)

2-2. Some files are removed because of debian packaging policy.
Some files related to five modules are removed. But as a default,
they are compile target although missing makefile.

modules:
 - cs46xx
 - cs46xx-new-dep
 - maestro3
 - ymfpci
 - korg1212

To solve this, it's to good to exclude these modules by configure option
or disable some codes related to them in configure script.
The latter is good to use this source with module-assistant.

This source makes no sence and currently we need to use the original alsa source.
I hope you to put high priority to this bug and release modified package as soon as possible.

Regards

Your bug report does not entirely correspond to my experience, using the Alsa-Ubuntu source available available below.

At point 2-1 you mention the files below are to be edited. However, the first does not seem to exist in that directory but only in the one below. The second is only created after the package is configured.
/include/linux/pci_ids_compat.h
/include/linux/i2c_id.h

Your cure does correspond to my experience. However, it needs to be applied to the files mentioned below. Thereafter the compile fails as described in your bug-report at 2-2 which does correspond to my experience.
include/pci_ids_compat.h.in
include/i2c-id_compat.h.in

Source package Alsa-Ubuntu:
http://www.voyage.hk/dists/0.7/alsa-driver/alsa-source_1.0.24+dfsg-0ubuntu1_all.deb

Maarten,
Yes. You're right. The two files are generated by running configure script from templates which you mentioned.

This week I review the patch and find the bug. It's in distinguish_kernel_makefile_and_source_dirs.patch in line 45 to 55.

+echo "\$(warning KBUILD_SRC=\$(KBUILD_SRC))" > "$dir"/Makefile
+kernelsrc=$(make -C "$CONFIG_SND_KERNELDIR" M="$dir" 2>&1 >/dev/null | \
+ sed -n "s#^$dir/Makefile:.*: KBUILD_SRC=\(.*\)\$#\1#; T; p; q")
+rm -rf "$dir"
+if test -z "$kernelsrc"; then
+ AC_MSG_RESULT(failed)
+ exit 1
+else
+ CONFIG_SND_KERNELSRC="$kernelsrc"
+ AC_MSG_RESULT($kernelsrc)
+fi

With configure script generated by autoconf, we fail to set $CONFIG_SND_KERNELSRC into $kernelsrc in Ubuntu environment.
I cannot generate fix patch with my poor skills... I hope this may help you.
