It works for me™.
I am using a slightly modified version of the Slackware-originated
SlackBuild that can be found at
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.
