Hi all, In order to use the latest kwintv with use of qt multi-threading I went to the trouble of upgrading to glibc-2.2.1, qt-2.2.3, xfree-4.0.2, freetype2 etc... I compiled qt but got binary rpms for the rest. My original system was a Mdk 7.2. After re-compiling kwintv ok I get this bleeding error at launchtime: $ kwintv Xl$ kwintv Xlib: extension "RENDER" missing on display ":0.0". KCrash: crashing.... crashRecursionCounter = 2 KCrash: Application Name = kwintv path = <unknown> Xlib: extension "RENDER" missing on display ":0.0". Does this mean that the xfree-4.0.2 I got from the cooker didn't have the RENDER extension compiled in? I searched my system and found /usr/X11R6/lib/libXrender.so.1.0 present. If this is it how do you load it (tried 'load render' in vain)? An xdpyinfo right now shows no RENDER extension indeed. I find the extension loading quite ambiguous cause you have modules, built-in extension and others. Can anyone please shed some light on this by checking with xdpyinfo and the contents of his XF86Config-4 file e.g.. Thanks for any help. Guy.
