What distro are you using?

What apps do you have installed - eg - Gnome,KDE,Mozilla,etc

You are going to have to manually rebuild the ld.so.conf file so do not reboot your system.

At the very least it will need /lib /usr/lib /usr/X11R6/lib.

You can use echo to rebuild it like so:

echo "/lib" > /etc/ld.so.conf <---- start it fresh
echo "/usr/lib" >> /etc/ld.so.conf <-------append to the file
echo "/usr/X11R6/lib" >> /etc/ld.so.conf

the >> means append and the > means start from new.

You can view the current libraries like so:

ldconfig -p <---this prints out the lib links which you can extract the lib directories from that you need to put in the ld.so.conf

or dump it to a file:

ldconfig -p > temp.ld

ld.so.conf only needs the directory names and it will link the libs from there. The ld.so.cache is what is getting printed out with ldconfig -p.

You can create a script with bash to automate this a bit and you can use cut and awk to get the names of the directories and then uniq to strip the dups. You can then dump these to a new ld.so.conf file.

If you want, I can come up with a script to do this if you are not that familiar with bash - just let me know.

I am useing a highly custom Lfs/slack 10 distro that i built my self.
I have
Kde 3.2.3 & QT 3.3.2
Firefox
Openoffice
Inkscape
Gimp
Java
NetBeans
Gambas

That's about it you could make a shell script if you wan't and post it and then make a KB submission for others to referance.

I have everything ldconfig -p prints out but i am still missing everything above.

My ld.so.conf

/lib
/usr/lib
/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib


After all of this i am going to build an automated ld.so.conf recover type appt. lol

Here it is - quick and dirty to get a new ld.so.conf from your ld cache:


--------begin below this line--------------
#!/bin/bash

ldconfig -p > out.txt
cat out.txt | cut -d ">" -f 2 > out2.txt
cat out2.txt | while read LINE; do
echo ${LINE%/**} >> ldsoconf
done
sort ldsoconf | uniq >> ldsoconf2
cat ldsoconf2 | awk '{ print $1}' | grep "/" >ld.so.conf
rm -f out.txt out2.txt ldsoconf ldsoconf2
-------------end above this line------------

I tried here on my test box and it works fine.

If any of you were on Tinyminds - my nickname over there was Fragadelic.

I use Tigger on all things linux so I decided to do it here too.

EDIT - made it remove the line that said how many libs were loaded so it will make a ready-made ld.so.conf - you can use this for your auto-regenerating ld.so.conf file.

Great everything seems to work..
You are the poster of the hour man thanks.
Question will this work in every case?
If not is there a way to make it work in every case?

[Tigger]

Check the post again - I just editted it to make a better file. I called it "ldrebuild" here when I made it.

Yes it will work on any linux box that has bash,uniq,cut,sort and awk commands available which is almost all distros - even small ones like feather which is what I created it on.

[comtux]

What kind of package manager are you useing?
tar.gz
tgz
deb
rpm
urpm
ebuild

Oh ya i had to add this to my ld.so.conf
/usr/lib/qt-3.3.2/lib

Wouldn't
slocate lib > temp.ld
work better?

[Tigger]

I use 4 distros right now:

feather linux - laptop, test desktop at work 300M installed
vector linux - I am a VL developer - used to be the Chief Architect of the SOHO branch - no time for that much dedication now but I still help them out
slackware - server at work - nfs,samba,tftp,ftp,printing - 580M installed
fedora - home server - soon to be replaced by slack

I really prefer either tgz with slapt-get or deb with apt-get.

I am a CLI freak so I do as much as I can there including installing packages and upgrading,etc.

Been using linux since '97 - developing with VL since 2002.

ldconfig is the best bet as it will provide you with all the actual libraries that are loaded in ld.so.cache. Not sure why it missed your qt stuff though. It does require that ldconfig wasn't run after the ld.so.conf file was corrupted though.

not all libs for all apps are in a lib directory though but you can try that and see how it compares to the ldconfig -p.

Ok you are my new best friend.
Search for my post.
I tried a test run and ahh it is better your way i am also not sure whty it mist my qt dir but ill figure it out and i did run ldconfig after i corrupted my ld.so.conf file
