Hi, not sure my subject made sense so i'll try to explain a bit further. Short version : I basically want to build my own kaffeine 0.8 source (including numerous patches) on my freshly upgraded ubuntu 11.10 (unity). Is it correct to assume that using your kde3 tde packages i'll be able to build my kaff source and run it on my unity system ? Can i build and run vanilla kde3 app source using your libs but not your desktop ? Long version : I found out a bit too late that kde3 libs were ditched so i'm now stuck with kaff 1.2 which is far from satisfying my requirements.. I've been trying for the past few days to figure out a proper way (meaning without breaking the current ubuntu kde5 libs) to restore kde3 libs on my ubuntu 11.10 system in order to build kaffeine but i'm no deb package wizard. As soons as i searched for kde3 i was pointed towards trinity and so found out about your kde3 desktop and ppa which probably includes all the required kde3 libs to run kaffeine. I've also tried to run your kaffeine 0.8 package but after a successful installation, it fails to run with an error. I've managed to run configure in my kaffeine source using the following command : #./configure --prefix=/opt/kde3 --without-xcb --without-lame --without-gstreamer --without-xinerama --without-oggvorbis --with-extra-includes=/usr/include/tqt/ the --without(s) are there to skip unnecessary parts and should be ignored but i had to add the tqt include path otherwise it was complaining about some missing tqt headers files which are located in the regular not /opt path. make then fails after outputing a very large quantity of "undefined reference to", like the last one here : .libs/playlistimport.o:(.data.rel.ro._ZTI15NoatunXMLParser[typeinfo for NoatunXMLParser]+0x10): undefined reference to `typeinfo for QXmlDefaultHandler' collect2: ld returned 1 exit status make[5]: *** [libkaffeinepart.la] Error 1 And i can't see any actual error statement but obviously something is not working. Thx for reading, any help wil be greatly appreciated. Marc
