Compile errors with latest alsa releases

Compile errors with latest alsa releases

[snookertb]

I am attempting to update the Sun JDS distro from alsa version 0.9.0 to 
a later version which supports newer Intel sound chips. I get the 
following errors in these two compiles. I ran versions 0.9.8 and 1.0.2c 
and they produced the same errors.

alsa-driver-1.0.2c compile error

Error in both cases error is triggered because of the kernel version of 
SJDS is 2.4.19-4GB. Is this alsa driver not supposed to be used with 
older kernels?

This is a function which doesn't exist in older 2.4 kernels, so ALSA
defines its own version.  It seems Sun backported some USB stuff from
a newer kernel.

Try to uncomment this function in adriver.h.

Thanks for responding. I had just about given up ...

I commented out the function definition of usb_make_path() in the alsa-driver-xxx adriver.h file and now it compiles without errors. Since usb_make_path() is wrapped in a kernel version it probably is true that Sun back ported some of the usb functionality.

SND_CTL_READONLY does not appear to be declared anywhere. I assume that this is also a function of new kernels, or Sun's implementation, and if I added the declaration to the alsa-utils-xxx somewhere it would be proper. Where should the declaration go? Any idea how to get the proper values?

Are you part of the alsa development team?

It's defined in alsa-lib/include/control.h.  You have to install the
alsa-lib package before compiling alsa-utils and alsa-tools.

SourceForge says no, the bugtracker says yes.  :-)
