[gentoo-user] what is /usr/lib64/debug ?

[Allan Gottlieb]

/usr/lib64/debug seems to have in it a duplicate (at least as far as
directory names are concerned) of much of /usr/lib64.

For example

    ajglap lib64 # /bin/pwd
    /usr/lib64/debug/usr/lib64
    ajglap lib64 # du -s * | sort -n | tail -10
    34020	mesa
    53148	gstreamer-0.10
    155992	icedtea6
    161360	llvm
    208932	qt4
    304016	xulrunner-devel-2.0
    308880	xulrunner-2.0
    618408	firefox
    669000	libwebkitgtk-1.0.so.0.7.2.debug
    1087848	libreoffice
    ajglap lib64 # 

Is this correct?  My system is ~amd64

thanks,
allan

Do you have the splitdebug [1] FEATURE enabled?

Bingo.

If I drop this feature (I turned it on for tracking a bug) will the
/usr/lib64/debug tree go away or must I delete it manually.

Also are there any other large subtrees I need to purge?

thanks for the help.

No need to answer these queries.  Everything is explained in [1]
above.
