I am trying to compile 3.1.5 on Ubuntu 7.10.

I am receving the following when I do make

[ 70%] Building CXX object plugins/bwscheduler/CMakeFiles/ktbwschedulerplugin.dir/schedulegraphicsitem.o

Having searched the forum I found that I may need qt4. I checked my os and found qmake
/usr/bin/qmake-qt4 -v
QMake version 2.01a
Using Qt version 4.3.2 in /usr/lib

I can see where I can upgrade qt to 4.4.
Can anyone help?

grab QT4.4 from your Distro's repo, might find it in a newer dist release if its not packaged for your current,

On Fedora 9 I had to grab it from the F10 development repo

You probably need to upgrade to 8.10 for Qt 4.4.
