thanks...

that build an OSS version...
So you should be at least:

./configure CC=g++ --with-alsa
(that works, creates a sndlib.a)

but (desirable to have jack support):

./configure CC=g++ --with-alsa --with-jack

stops with:

$ make
g++ -c -DHAVE_CONFIG_H -I. -g -O2 -fPIC   -I/usr/include headers.c
g++ -c -DHAVE_CONFIG_H -I. -g -O2 -fPIC   -I/usr/include audio.c

depends on how you built sndlib, if with alsa and you have gsl installed
then you need to add `gsl-config --libs` to the libs you link against
(did that manually).

It then builds but there are problems as you note in the other message -
a bunch of 'undefined sharp expression' messages. 
 
Thanks for the help. 
(and have a good trip!)
