1.0.24 alsa-driver compilation problem

1.0.24 alsa-driver compilation problem

[Grzegorz Daniluk]

Hi,
I'm trying to cross-compile the latest 1.0.24 alsa-driver for my 
embedded system (using SH4 processor and linux kernel 2.6.35). Before 
compiling 1.0.24 I did turn off the alsa in kernel configuration 
(leaving just Sound card support enabled). So I run as follows:
./configure --with-kernel=<where_my_kernel_src's_are> 
--with-build=<where_my_kernel_src's_are> --with-cross=sh4-linux-gnu-

and then 'make'. However, during 'make' I've noticed the following warning:

WARNING: "register_sound_special_device" 
[/root/alsa-driver-1.0.24/acore/snd.ko] undefined!
WARNING: "unregister_sound_special" 
[/root/alsa-driver-1.0.24/acore/snd.ko] undefined!

and then when trying to insmod the snd.ko module the following error 
appears:

snd: Unknown symbol unregister_sound_special (err 0)
snd: Unknown symbol register_sound_special_device (err 0)

thank you for your help,
best regards,
Greg

ok, when I add the --with-oss=no option to ./configure those warnings 
disappear and I can load the module without any problems. But still.. 
how can I compile alsa to have also oss emulation (I need /dev/dsp to 
access sound codec from my software).

You need to enable OSS emulation in the kernel; try CONFIG_SOUND_PRIME.
