[gentoo-user] Removing unneeded libraries

Hi!

Does "eclean" or "emerge --depclean" remove libs that are orphaned? And if not, how can I find out if a lib could be removed from the system?

The problem is, that my /usr/lib/... and /usr/include/ almost 1 GB in size! I think there is a lot of unneccessary stuff 


Regards, JC!

"emerge --depclean" does. Orphaned meaning "installed as a dependency
of something that is itself already deinstalled" (i.e. not in the
world-file). Be sure to check the list with "-p" before really doing
this!

Hm, I don't think so. Mine is similar: about 950MB. OpenOffice takes
370MB (it's the -bin version, it includes a lot of redundant
libraries). My GCCs take about 200MB (including java support). Then
there's Perl, 2x Python, 2x PHP and Wine's archive of windows DLLs. So
I think about 1G is quite normal for a typical desktop.

Mine is 1.1GBs here.  I have a lot of "stuff" installed.  ;-)

Yes, provided you have not modified the files yourself.

Sounds about right, but this command will generate a list of all
library files that portage things should be installed:

find /var/db/pkg/ -name CONTENTS | xargs grep /usr/lib/lib | awk '{
print $2 }' | sort

You can diff that with the output of "ls /usr/lib/lib*" to see what
may be there that portage doesn't know about.
