Was the Qt4 port abandon.
Is there a separation between the business logic and the UI or is it all intermingled. Trying to access how much work it will be to do a Qt4 port.
Where are the .ui files?
Why doesn't it use qmake?
Hate to bump an old thread, but I've been wondering too.
Qt3 has been long abandoned by upstream (Trolltech; now Nokia) and slowly all the Linux distributions are dropping Qt3 from their repositories. I lost the ability to run Qucs when Gentoo pulled Qt3 from its repository (and yes, I know there's an overlay that includes Qt3, that isn't the point).
What is needed in order to get the Qt4 version of Qucs workable?
Also Ubuntu has now dropped support for qt3 and removed qucs from their repo. I am affraid that the qucs development is dead as there has not been any activity since 2011. Meanwhile I am trying to port the new qucs version to QT4, if I succeed I will post the changes on github.
For now it is still possible (at least in Ubuntu 12.10) to use the libqt3-mt-dev deb files from the 12.04 repository, so qucs can still be compiled as it is.
I have made one!
