There's .deb available from the Sf.net download page:

• http://downloads.sourceforge.net/qtractor/qtractor_0.4.1-1_i386.deb

Please note that's built to Ubuntu 8.04 LTS. Might not work for you, though.

Anyway, you should be able to build it from source without problems, provided you have all the mandatory software requirements installed. Remember that you should install the corresponding development support packages, being those the ones with the -dev suffix in their name. You'll need, if my memory doesn't fail me,

• Qt 4: libqt4-dev
• JACK: libjack0-dev
• ALSA: libasound2-dev
• libsndfile: libasndfile1-dev
• LADSPA: ladspa-dev
• etc.

and try to comply with all suggested recommendations and dependencies you might get from your package management software, whatever it be.

Cheers
