Solution 1:

apt-cache search libqt | grep headers returns

libqt3-compat-headers - Qt 1.x and 2.x compatibility includes
libqt3-headers - Qt3 header files
libqtgstreamer-dev - Development headers for QtGStreamer

That is a basic example of how to search for dependencies you don't have. Also see http://ubuntuforums.org/showthread.php?t=124483 post #8 for a more thorough explanation.

It looks like you're going to want to grab the second one and install it. If you don't know how: sudo apt-get install libqt3-headers will do the trick.

Solution 2:

At least for me it worked out to

sudo apt-get install build-essential libqt4-dev libqt4-qt3support automake libtool gperf flex bison git cmake

from https://github.com/Qucs/qucs/wiki/Build-Linux

and go on with

./configure
make
sudo make install
