Hi Martin,
You should install alsa-driver before alsa-tools, as it will install the hdsp.h file on your system, containing the missing declaration.
Thomas
Ooops, I misread your subject line. This is because the driver version included in 2.6.0-test11 is a little bit outdated. Update your kernel tree with latest alsa, and compile again, then.
there are configure options to specify the header files for alsa-kernel. one is --with-kernel and another is --with-soundbase.
the former specifies the top path of 2.6 kernel source tree, and the header files in that tree will be used. the latter specifies directly the path of alsa-driver's include directory.
for example,
./configure --with-kernel=/my/src/linux-2.6.0-test9
./configure --with-soundbase=/somewhere/alsa-driver-1.0.0/include
when no these options are given, the standard path, i.e. /usr/include/sound will be searched.
these options are necessary only for (some of) alsa-tools. usually, applications don't need (and shouldn't) access to the kernel header files.
I used the hdsp.h header file to ease the task of building userspace application using the hwdep interface to communicate with the driver (sharing structures and type definitions).
If this was a bad idea, I'll reconsider it, no problem.
