Well, I'm typing this from kde3.0.3 compiled with gcc3.2 on a Debian stable system. It's running great, no crashes, no nothing. No artsd, though not because of artsd problems: I just don't want sound at work, in a remote-X situation, with no sound card on that workstation (or the X application server) =) > Does anyone know if it is even worth upgrading from > gcc 2.95.3. Yes. Better C++ support. It doesn't change THAT much for KDE itself. It's just plain better altogether, probably optimizes faster, and is supposed to be with a stable ABI. > Is gcc 3.2 any faster? Compilation itself is slower, and it's definately noticeable. I'd say half as fast, and I'd advise you to use --enable-final on everything you can (whole of KDE for example). Do the applications run faster? Not sure. They appear to, but then again, I went from KDE3.0.1-gcc-2.95-4 to KDE3.0.3-gcc-3.2 so part of the speedup might just be KDE bugfixes. (Or a lesser load on the application server, for that matter) > Finally, what happend to objprelink? Not sure. The plan is for gcc to do most of what objprelink was doing, but I have no idea how far they got with that. Moreover, I seem to recall that you don't need to give a ./configure parameter anymore, one just installs objprelink and it should 'just work'. Can anyone confirm? > I saw something about newer linkers not needing it because they did a good > enough job on there own.

Quite true! =) Have fun, Chris -- Maybe computer science ought to be taught in the School of Philosophy Christian Lavoie, clavoie@bmed.mcgill.ca http://www.christianlavoie.com >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
