I compiled ardour3 from source, as well as Jack. When I try to start ardour I get the following:

Here's some more hopefully helpful info:

Kernel: 2.6.22-14-generic
Distribution: Ubuntu 7.10 x86_64
libjack0 and libjack-dev Version 0.103.0-6ubuntu1
Jack jackd 0.110.0 (with alsa support)
Ardour The latest SVN build for version 3.

Thanks for any help, I appreciate it. =)

You probably had JACK already installed. You cannot (without knowing quite a lot about Unix) have two versions of JACK installed at the same time. Go back to your JACK source tree, type "make uninstall". Then re-run ./configure with --prefix=/usr so that it will overwrite any existing installation. Either that or force removal of the pre-installed version.

Thank you so much Paul... you rock!

That worked! I know it's not much, but I'm making a $25 donation right now.

Thanks again. =)

Another closely related follow-up question...

I got jack and ardour working, however, now when I try to install any software using Synaptic Package Manager and that software depends on libjack0.100.0-0 or higher, it doesn't see that I already have it. Is there a way to make Synaptic see that libjack is already there? I tried doing something like, PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/path/to/pkgconfig_for_jack", but that doesn't seem to work.

Thanks in advance.
