hi,
i recently installed jackd (using apt-get install) on debian lenny. i didn't push it to its limits but it seems to work fine (with alsa).
later i tried to install oddcastv3 (from source) but the configure script aborts with:
configure: error: Could not find jack/jack.h Install jack headers to build oddcast
i checked on a debian etch box running jack.d and the headers are in /usr/include/jack/
i reinstalled jackd with
apt-get remove/install(no difference),
apt-get -b source jackd (failed because of unmet dependencies), and
from source (./configure did not find alsa, only oss, so i didnt `make && make install`).
i also tried:
mkdir /usr/include/jack/
cp /location/of/source/jack.h /usr/include/jack/
oddcastv3 still didnt find jack headers.
any idea why jackd in lenny does not install headers?

Hi

If it's a program using jack as a library, I think the package you want to install is libjack-dev.
