This is possibly more a Timidity question, but I am still waiting for
confirmation from the Timidity mailing list, and it relates to ALSA
too, so maybe someone can help in the meantime.
I am trying to use Timidity as a soft synth for Rosegarden. Timidity
2.11.3 builds OK with the default configuration, but then "timidity
-iA" complains that the interface is not compiled in. The problem is
that when I attempt to configure alsa-related options the build dies
with C errors. Eg. "./configure --enable-audio=alsa" falls over in
alsa_a.c with lots of errors about unknown storage sizes, undefined
symbols, undeclared types, wrong numbers of arguments. (Detailed log
in the first attachment.) It looks to me as if I am getting the wrong
header file, or else a broken header. "./configure
--enable-audio=alsa --enable-alsaseq" has much the same problems: lots
of compile errors in alsa_seq.c . (Detailed log in the second
attachment.)
Digging around trying to find out what was going on I was surprised to
find the directories "/usr/include/{sound,alsa}", which contain
different versions of "asoundef.h" . If I figured this out right the
files in "/usr/include/sound" are installed by alsa-driver and the
ones in "/usr/include/alsa" are installed by alsa-lib? Could I be
getting the wrong "asoundef.h", or is that a red herring?
Cheers,
Jeremy
