Know it's been a while, but I have finally had some time on my hands to look at it again. I used a CVS snapshot from 2005-06-20 and the patch applies cleanly. alsa-driver/ builds and installs without trouble. However, alsa-lib won't build - with and without the patch. Using a CVS snapshot as of today, alsa-lib still refuses to build - and the patch also fails :-/. The patch is not in CVS (yet?) ? At least I haven't found any references to IFACE_USB_CTRL in alsa-kernel/include/asound.h. The alsa-lib build error is gcc -shared .libs/conf.o [...]-Wl,libasound.so.2 -o .libs/libasound.so.2.0.0 /usr/bin/ld: .libs/libasound.so.2.0.0: undefined versioned symbol name snd_pcm_hw_params_get_buffer_size_max(a)ALSA_0.9 /usr/bin/ld: failed to set dynamic section sizes: Bad value collect2: ld returned 1 exit status When I try to do the steps in cvscompile manually I get the following: jhje@flyvehest:~/alsa-cvs/alsa-lib$ automake --foreign --copy --add-missing src/Makefile.am:21: invalid unused variable name: `AM_LDFLAGS' Must be something obvious since the error is the same between the two snapshots (?).
