Most of them do not use Phonon. My theory is that a dud revision of KApplication "escaped" in the aftermath of the KDE 4.6 release and I checked out the source code at a bad time, but now I find I am unable to test that theory. I do not know gdb. I have rarely, if ever, used on-line debuggers as they have not been much use with timing-dependent or data-dependent problems in the on-line and real-time systems I have worked on. I would prefer to check the above theory ATM. I would have liked to looked at revision history in WebSVN online, but now KDE is in git and I can find no equivalent of websvn. I looked at http://techbase.kde.org/Development/Tutorials/Git and http://community.kde.org/Sysadmin/GitKdeOrgManual and then https://projects.kde.org/ and http://quickgit.kde.org/ but I cannot find a revision history for kapplication, only chronological lists of revisions. GitKdeOrgManual invites me to log in on https://identity.kde.org/ which I tried, hoping to find out more. But my developer's ID (ianw) and password do not work there. I seem to have been disenfranchised ... :-( I tried to re-register but it asked for an email address as ID, but it would not accept mine and declared it invalid ([email protected]). Maybe I should re-build Qt and KDE from sources again and hope that KApplication comes good. But that is a very time-consuming process and one I am not prepared to undertake with no guarantee of success. I looked at the http://techbase.kde.org/Getting_Started pages but swiftly became confused by the many alternatives and tables and really do not know where to start. I used to know my way around those pages a year or so ago, but now they look like a foreign country to me. The truth is that I have been unavoidably out of touch with KDE development, including the move to git and all that, since about July or August last year. I think I used the kdesrc-build script in January, hoping to find an easy way to go, but I had to tweak a lot to get all the pre-requisites and modules from all the various locations (git, SVN and sundry dependency sites) and get them to build. Would kdesrc-build work any better now? I have been a developer on KDE Games for 7 or 8 years, but now I am ready to walk away. I feel I have had enough. There seems to be too much change and re-learning required just to keep an application running, without being able to consider writing anything new. And the more change there is in the KDE libraries, the more regressions in previously working applications there are to deal with, costing developers more lost time. All I am trying to do at the moment is find out why Phonon will not play sounds correctly in KGoldrunner. In December I found Phonon's performance was so bad that I had to disable KGoldrunner's sound feature completely for the KDE 4.6 release. I just want to rebuild my game and another one (to investigate a bug report) but I cannot get to first base with either game, i.e. I cannot build and run them from source. Always FP exception in KApplication ... What should I do? Ready to give up ... :-( ... Ian W. >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
