kde4 will be based on Qt4... and kde 3.5 uses Qt 3 and it can't be compiled with Qt4. Unfortunally we'll have to wait quite a long time for kde4..

pkg-config doesn't pick up automatically the QtGui of qt4. Is this a bug? or intentional even? QtGui.pc is shipped !

From the KDE requirements list: http://www.kde.org/info/requirements/3.5.php

Code: Select all

Qt >= 3.3.2

Was my fault - the pc files should be installed in /usr/lib/pkgconfig, and not /usr/lib/qt4 like they were. qt-4.1.0 fixes this.

I'd say 4.0 > Qt >=3.3.2

Qt4 comes with some api-changes, it's neither source nor binary compatible with Qt3, so there's no chance running kde3x on qt4x. We'll have to wait for kde4

I've heard there have been some builds of KDE3.5 against QT4. And QT4 provides a library so you can link to obsolete parts of QT3 and map to QT4...

Well,

QT4 comes with a lot of API changes, and a Q3Support, which maybe won't work for every application.
QT3 Support is added by the value QT += QT3SUPPORT in the *.pro file. Think that's posible to add.

On my system I work with qt3 and qt4 and setting the CLFAGS and LDFLAGS to the qt4/qt4 include and library directories.

QT += QT3SUPPORT in the *.pro file only includes the Q3* classes, but you still have to go through the code and change for example QVBox to Q3Vbox. It's not an automatic process. Unfortunatelly, Qt4 is source and binary incompatible with Qt3...

Since QT4 portage has FHS compilant, how can use this version to build KDE svn trunk branch, I tried to set --with-qt-includes=/usr/include/qt4 --with-qt-libs=/usr/lib/qt4, but arts configuration always failed even I changed the values specified for the configure script.
