[gentoo-user] Changing libaries

Hi!

I've already asked this question on gentoo-user-de but I've got no - let's 
say - convenient answer. Therefore I'll try my luck here:

Another user had some trouble because Kaffeine couldn't play .ogg-files.
In the end we found out that he activated the necessary USE-flag and 
re-emerged xine-lib but Kaffeine kept using the old lib which was still in 
RAM, I presume.

Naturally, the problem was solved when he rebooted but I wonder how I could 
achieve the effect without rebooting.

Thanks in advance

Florian Philipp

Nope, it might even be left on disk, at least as long as it is still
referenced from open file handles. But it doesn't really matter if that
library just "is somewhere". It matters whether the (instance of the)
application using it has still opened it.

Close Kaffeine. That might be difficult if Kaffeine somehow stays
resident or has some "Quick start" facility (like kdeinit and stuff).
Check "ps" output and use "kill". At least, closing the user's session
is enough (if that plugin isn't run by the desktop manager, then I'd
suggest to kill X in order to close the DM's session as well).

For most applications you simply have to restart the application.  Next 
time the process starts perform dynamic linking, which accesses the 
filesystem and picks up the new library.

KDE applications started under the standard KDE environment have dynamic 
linking done for them by kdeinit though, so shared libraries stay loaded 
(but possibly swapped out) persist for as long as the kdeinit process 
lives.  So, you'll have to restart the kdeinit process, this usually 
involves logging out and logging back in, although kdm might (I don't 
think so, but might) require you to restart X.

Alternatively, you might be able to get around this by prelinking, or at 
least telling KDE that things are prelinked (even if they aren't) I 
believe kdeinit drops this behavior if KDE_IS_PRELINKED=1 or 
KDE_IS_PRELINKED=true is in the environment when kdeinit starts.

You can NOT simply kill the kdeinit process unless you want KDE 
applications started by it to start "mysteriously" dying.
