[Buildroot] Cannot build a worling alsactl or alsamixer using buildroot

[Buildroot] Cannot build a worling alsactl or alsamixer using buildroot

[Dirk Vermaak]

Hi,
For over a week now we have been trying to build alsa-utils to work on our 
sam9269-ek development board with a 2.6.24.4 kernel patched with the AT91 
patch, and the first experimental patch. We use the buildroot environment and 
have everything else working fine. I have scoured these lists and found a few 
threads that discuss having to change the make file for alsa-utils. So far 
nothing we do appears to change the behaviour.

with alsa lib and utils we have tried

1.0.14a 
1.014a with the  -mabi=aapcs-linux option
1.014a with the  -mabi=aapcs-linux and --with-versioned=no
(both of these changes I found here on the site)

Folllowing this I tried the latest Alsa stuff (1.0.16)  including patching 
both the lib and utils make files with the patch from Daniel Laird and Matt 
Dombroski. 

All of this appears to be of no avail. 

alsactl always returns : Cannot read control '2,0,0,Master Playback Volume,0': 
Inappropriate ioctl for device

alsamixer returns 

ioctl(3, USBDEVFS_IOCTL, 0xbeae7188)    = -1 ENOTTY (Inappropriate ioctl for 
device)
write(1, "\n", 1
)                       = 1
write(2, "alsamixer: function ", 20alsamixer: function )    = 20
write(2, "snd_mixer_load", 14snd_mixer_load)          = 14
write(2, " failed: ", 9 failed: )                = 9
write(2, "Inappropriate ioctl for device", 30Inappropriate ioctl for device) = 
30
write(2, "\n", 1

Does anyone have any ideas as to how to get a working build of Alsa. Any help 
would be greatly appreciated.

Thanks,

Dirk.

For the information of others, we have fixed this problem, or rather worked 
out the correct set of make values to make it work.

There are two values in the alsa-lib.mk file that need to be correct.

If you are an OABI built kernel, make sure you do not have -mabi=aapcs-linux 
set in your CFLAGS.

If you are an EABI built kernel, make sure you do have -mabi=aapcs-linux set 
in your CFLAGS.

Then in both cases, in the ./configure part make sure you add 

--with-versioned=no

We have tried this with 1.0.15 alsa-utils and alsa-lib and all is working, 
alsamixer, aplay etc. 

Thanks to the others who have posted about these problems. This is just a 
summary of their work.

Cheers,

Dirk

I have posted patches for ALSA-utils/lib 1.0.16 (see bug 4014) these look
like above.  What is the --with-versioned=no option.  I have not used it but
it all works for me with 1.0.16. 
Maybe you could take a look at the patches on 4014 and update if necessary.
That way we can close BUG ticket and update ALSA both of which are good :-)

Cheers
Dan
