Baho, All, I was working with the new Qt3 build on x86_64 and I ran into an xsession crash that I need help identifying the cause. I have put the .xsession-error, trinity-qt3 file list up at: http://www.3111skyline.com/dl/dt/trinity/err/newqt3/xsession-error-new-qt3.txt http://www.3111skyline.com/dl/dt/trinity/err/newqt3/new-qt3-no-work-file-list.txt I have reinstalled an older build of Qt3 and it works fine, so there is something in the new build. The PKGBUILD is modeled after the one you are using, but I have enabled the doc and examples. I have put the PKGBUILD up here: http://www.3111skyline.com/dl/dt/trinity/err/newqt3/PKGBUILD-qt3-trinity Looking at the xsession-error file, the following jump out at: DCOP: register 'anonymous-1000' -> number of clients is now 4 DCOP: 'anonymous-1000' now known as 'kwin' kdeinit: Got EXEC_NEW 'kdesktop' from launcher.

I can't explain the first 2 error blocks, but the "dcop: error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory" is self explanatory. However, if you check the file list link above, libqt-mt.so.3 is there: 07:36 alchemy:~/tmp> grep libqt-mt.so.3 new-qt3-no-work-file-list.txt /opt/qt/lib/libqt-mt.so.3 /opt/qt/lib/libqt-mt.so.3.3 /opt/qt/lib/libqt-mt.so.3.3.8 So, why is this file not being found? I don't know what is causing this, so I'm punting to the smart folks for help. I'll have a bit more time to dig into this this weekend, but if you have any thoughts, I would appreciate any help you can give to shorten the dig :) -- David C. Rankin, J.D.,P.E.
