I am using a slightly modified version of the Slackware-originated SlackBuild that can be found at ftp://ftp.gwdg.de/pub/linux/slackware/unsupported/kde-3.5.10-for-slack13.0/source/qt3/ This is a unusual SlackBuild, because it builds qt3 in /opt/kde3 (Patrick Volderking says in the scripts that building it in /tmp frequently led to wrong packages). Also, I posted my own version recently on the list, it is essentially the same with additional patches. I am building Trinity under Slackware 13.37 with full KDE4 alongside (KDE4 is my main desktop now, no kidding), and: -dependencies such as qt3, qca and poppler-qt3 compile with the unsupported scripts from the Slackware mirrors, with /opt/kde3 prefix -arts, dbus-tqt, dbus-1-tqt, tqtinterface compile without errors, with /opt/kde3 prefix -kdebase and kdelibs also compile without errors, still in /opt/kde3, but when I launch any KDE3 program, it doesn't manage to load any library in /opt/kde3/lib/kde3. However, when I built qt3, Trinity was not installed, but only KDE4. I will put the build scripts and the patches online when I have more time (==soon), right now I have my exams. The patches basically fix kconfig_compiler detection (with the SVN version it uses the KDE4 one) and enforce the use of dbus-tqt.pc for the build of kdebase. > > The build script is here: > > http://svn.trinitydesktop.org/svn/trinity-packaging/arch/master/trinity-qt3… > > The Qt3 package built fine when I uploaded it a day ago: > > http://svn.trinitydesktop.org/svn/trinity-packaging/arch/master/src/trinity… > > Any help appreciated :) > --------------------------------------------------------------------- To unsubscribe, e-mail: trinity-devel-unsubscribe(a)lists.pearsoncomputing.net For additional commands, e-mail: trinity-devel-help(a)lists.pearsoncomputing.net Read list messsages on the Web archive: http://trinity-devel.pearsoncomputing.net/ Please remember not to top-post: http://trinity.pearsoncomputing.net/mailing_lists/#top-posting
