Side note: TDE will probably have porting problems too due to limited number of contributors. There are actually two people that do most programmer's work, and a few porting enthusiasts. So do TDE could not replace KDE3 fully. :( >From the other side, slower archs probably will use XFCE, LXDE or something custom...

You tell me. Not too hard for KDE 4. But I still hope to find better way than this "/opt"-ism. My personal goal is to make KDE 4 co-build with KDE 3, and to make libs and pimlibs from KDE 4 co-exist with KDE 3. But I didn't even started moving in that direction, there is too much other work. >> 2) move to trinity with /usr/local/trinity/*, adjust the quirks and >> provide an upgrade path for kde3 + have kde4 with /usr/local/kde4/*. >> both independent. > > Depends on having trinity up and running. > >> 3) add tde (/usr/local/tde/*) + kde4 (/usr/local/kde4/*) + kde3 >> (/usr/local/kde3/*), then remove kde3 after sometime, providing >> upgrade for kde3 users. all independent. > > probably desireable. > >> what about the problem of incompatibility for kde3 -> kde4 or tde -> kde4? > > I don't know. You tell me how much incompatibility there is. This could not be done fully automatical. We could probably use some stuff from OpenSUSE, they did amazing work on making transition transparent, but even there were a lot of problems. >> keep in mind, future kde5 is released late next year it should have >> /usr/local/kde5/*? > I'm not at all sure kde5 will be THAT incompatible to kde4. Yes, we could treat KDE 5 the same way as KDE 4.

I have some crazy ideas like porting KDE3 to CMake, but before talking loud about them sound I should try to try starting myself. -- WBR, Vadim Zhukov
