No $QTDIR variable, configure error

[transistortoaster]

Hello,
I request some advice. I have a HDinstall of the Knoppix 4.0 DVD, which is now about 2 weeks old. I am trying to to a configure for "brahms" from source which uses QT3. The configure says error Qt (Qt>3.0.1) headers and libraries not found. However, if I do a dpkg - l |grep qt, I see that I have all the qt3 libraries, including the -dev ones. I found the files in /usr/include/qt3 and /usr/lib/qt3 which should be correct. When I do "echo $QTDIR" there is nothing. I would like to treat the main cause of the problem and not just patch up the symptoms. Fundamentally, QT3 is an important package and should have been set up properly.
Question1) What is the right way to have the $QTDIR registered
Question 2)There are some variables for library and include search paths. What are the right names and what should I include with them? Do I also need a PKG_CONFIG_PATH set to something too?

From another thread (http://www.knoppix.net/forum/viewtop...771&highlight= ), somebody did "export MOC=/usr/share/qt3/bin/moc && configure --with-qt-dir=/usr --with-qt-includes=/usr/include/qt3 -with-qt-libraries=/usr/lib/qt3 --enable-mt ". That thread is dated from 2003 and I don't know what all of it does exactly. What is MOC all about?

Any advice is greatly appreciated.
Frank

Have you tried "export QT3DIR=/usr/share/qt3" That directory has ./include and ./plugins simlinks on my system (Knoppix 3.

Close but no cigar. On Knoppix 5.3.1, I did that... and the ./configure kept complaining about no headers found after using QT3DIR=

checking for Qt... configure: error: Qt (>= Qt 3.0.2) (headers and libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

Then I set it to QTDIR=

Ok now maybe I can find out what file in the subdir tree I just copied is 4GB... probably a knoppix.iso come to think of it.
Well more likely... on to the next error.
