Hi! Recently I found somewhat strange patch to Mk/bsd.kde.mk : Revision 1.47 Globally disable -Wl,-as-needed for all users of USE_KDELIBS_VER. Binaries linked with -pthread and -Wl,as-needed will have all references to libphthread stripped (reason/reasoning unknown), causing funny runtime errors when Qt decides to fire up a thread. Which I find somewhat strange, as I believe that there were reports of a quite measurable increase in start-up time for KDE applications due to the use of "-as-needed" linking flag. As far as I can see there are at least two ways to work around the issue described above. The brute-force and dirty solution is to add something like "-noas-needed -lptread -as-needed" to LDFLAGS. In a more cleaner way, as it is libqt-mt who needs threading in the first place, why not link it against libpthread? Additionally this should solve the problems with qtk-qt-engine, which fails to load now for non-threaded applications. -- Best regards, Alexander.
