Hi. I just cleaned my system and made a fresh "svn co" of trunk, and also run configure as we do on the build bots.
I have (of course) installed all ubuntu requirements as the wiki building instructions says, however I still get errors of missing packages (most I have solved). There are 2 switches, where I cannot guess which packages I have to install on ubuntu 12.04 (64bit): --enable-gstreamer --enable-opengl thanks in advance for any help. rgds Jan I.
