Btw; ecasound compiles under FreeBSD, so OSX shouldn't be impossible.

You could always try setting prefix to /sw, ie. "./configure
Another way is to just disable curses. It's not used for much. You can do
this with "./configure --disable-ncurses".

This is weird. nanosleep() is part of POSIX.1b standard so it should be
available in OSX. You could try replacing instance of nanosleep with
usleep() (or whatever is installed). nanosleep() is only used in a few

Generally the difficult areas are:
Ecasound uses the POSIX APIs for these functions, but they are not
available on all platform or on some platform linkign to some special
library is needed. For instance, check ecasound's configure.in for string
"bsd" and you'll find at least one place where extra steps have

Yup, ecasound can be compiled (and used) without support for soundcard
drivers. At some point I might add support for PortAudio, which is
a crossplatform audio API that is available for both Linux and OSX
(among many other platforms). See http://www.portaudio.com/
