thx for the update. This is some very useful information, like tqtinterface has to be installed in /usr wich I didn't do :(.
From the wiki: :)
NOTE: Until the cmake migration is fully completed, tqtinterface should be built to install with a $PREFIX of /usr rather than /opt/trinity.
That might also be the reason why tdelibs fails to build with automake complaining that qt4 cannot be found although tqtinterface has been build only with qt3 and no kde4/qt4 is found anywhere on my system. I'll give your workaround a try tonight. If you find the time, please post the info on the howto pages to avoid double posts :-)
Regarding the Qt4 messages, from the wiki:
NOTE: To avoid build problems with automake when Qt4 is installed set the following configure options:
--with-qt-dir=${QTDIR} --with-qt-includes=${QTDIR}/include --with-qt-libraries=${QTDIR}/lib
NOTE: The only package built with cmake that requires Qt configure options is tqtinterface: -DQT_VERSION=3.
The cmake packages find Qt3 just fine, but tqtinterface needs the -DQT_VERSION=3 option to avoid trying to build against Qt4.
The --with-qt-includes option might get complicated because right now there is a tqtinterface build presumption that (t)qt3 installs the header files to ${QTDIR}/include/(t)qt3. I'm trying to debug this so Tim can provide a more robust solution.
