Hi,
Can someone please advise me on these issues:

1)I've installed xine on my fedora core 2,but I downloaded the newer version today and want to get rid of the earlier version.I have xine installed in /usr/local/lib.I compiled xine from source and the latest package I have is in the same format.I can't do an upgrade.So can someone please tell me how to remove the earlier set and what files I need to remove.I don't want to end up deleting important files.Also I forgot what parameters I must pass so that I can install a frontend to xine.

2)I tried installing Lyx on my system.it listed xforms as one of the required programs.So I got the xforms pack and installed it.But then when I tried to compile Lyx it just got stuck during the make process and i couldn't proceed.I think that the xforms pack was buggy.How can I remove the xforms set and what files do I remove?Also,is version 1.0.90 the latest xforms version.Where can I get the stable version.Please help.

did you install your previous version from source too?
do you still have the source-tree you compiled it from?
you could then do a "make uninstall" - or check the Makefile to see where it installed the files and remove them manually

if you have the old source but did clean it - you can still use it to uninstall what you have installed - provided, that you know, how you run the configure-script...
in that case you could run configure again with the same arguments as you did then and after that use the so configured source-tree to run "make uninstall"

you know that xine consists of the xine-libs and the xine-ui - the last one providing a graphical user-interface ?
you gain not much from installing just a new user-interface...

I don't know about xforms but remember, that there where problems compiling it...
You can build lyx using the qt-libraries instead of using xforms - if you happen to have them...
