Scanning the system for broken executables

fturco · 2012-09-23 20:01:05

Hello. I noticed that on my Arch Linux system there are lots of executable files that seems to be broken in that they need missing libraries. I scanned the system with the following command (don't know if it's correct):

# find / -type f -executable -exec bash -c 'ldd $1 | grep -q "not found" && echo $1' bash {} \;

Basically I'm trying to get a list of executable files that when scanned with "ldd" results in "not found" entries.

My list is quite long (I manually filtered it somewhat):

/usr/bin/jack_netsource
/usr/bin/playdv
/usr/sbin/sensord

For example running "ldd" on one of the previous files results in three missing libraries:

ldd /usr/lib/kde4/kcm_adobe_flash_player.so | grep "not found"
	libkdeui.so.5 => not found
	libkutils.so.4 => not found
	libkdecore.so.5 => not found

This "broken" library belongs to a package I need (the flash plugin):

pacman -Qo /usr/lib/kde4/kcm_adobe_flash_player.so
/usr/lib/kde4/kcm_adobe_flash_player.so is owned by flashplugin 11.2.202.238-1

The last step is to obtain the name of the package I need to fix the problem:

for i in libkdeui.so.5 libkutils.so.4 libkdecore.so.5; do pkgfile $i; done
extra/kdelibs
extra/kdelibs
extra/kdelibs

So it seems that the flash plugin depends on KDE (or a part of it). But I run GNOME and I prefer not to install anything related to KDE. Similarly, when repeating the previous steps on all the other "broken" executables, I get many other missing libraries I frankly don't feel I really need.

At this point I'm asking the following questions. Is this behaviour normal on a Arch Linux system or on a Linux system in general? Should I install all missing libraries in order to prevent breakage? Should I instead avoid doing that and keep my system the way it is now?

I'm a new Arch Linux user and I'm just curious.

Thank you.

i'm not an expert but i think that some "not found" regards only optional libraries
and as an archlinux user i say you: "if you don't meet problem, don't try to find it" -> "if you system run, don't try to fix it"
