On Linux I run ./autogen.sh and then ./configure. I get this error:
config.status: error: cannot find input file: `Sources/Sound/Makefile.in'
Sources/Sound/Makefile.am does exist but I suppose it's not producing a Makefile.in for some reason. The sound configuration stuff says:
checking asoundlib.h usability... no
checking asoundlib.h presence... no
checking for asoundlib.h... no
checking alsa/asoundlib.h usability... yes
checking alsa/asoundlib.h presence... yes
checking for alsa/asoundlib.h... yes
Is it possibly some logic error because of the alsa/ subdirectory? Haven't looked at the code.
