Title:
Need to fix bugs causes compiling error. One is related to Open Sound
System Emuration. The other is caused by patches.
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
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.
