I see, thanks for that. I was already trying this path after reading the reply of Anders.
I installed the rpms that were suggested by wireshark/tools/install_rpms_for_devel.sh
I then also installed qtchooser-39-1.fc20.x86_64, but configure is still unable to find it somehow. I guess I need to help it a bit somehow, I'll keep trying!
Jonne.
