Hi Guys

Installed Gaim and FireFox, but when I try to run them I get this error:

error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file. No such file or directory

There is a symbolic link in /usr/lib/ for it and a file called libgtk-x11-2.0.so.0.9.1 - and I'm stumped on how to fix this. It seems to be a fairly common problem (Google), but I've found nothing for SlackWare 9.1 on how to make Gaim and FireFox work.

Any and all help appreciated.

DId you run 'ldconfig' after installing the libs?

Hi Gnashley

err, what lib's? All I did was find the tgz for Gaim (an older one for Slack 9.1) and FireFox (the current one, felt brave) and installed them, then got hit with the error when I tried to run them. What's really weird is that when I installed Gaim and got the error, I Googled and found lots of people saying that a current install of FireFox would fix the error. ***not true***

***scratches head and wonders***

PS: still need help on this

PSS: what's ldconfig and how do you use it?

Just did a fresh install of Amigo and got that nasty libgtk-x11-2.0.so.0 error after installing Firefox (0.9 for Slackware 9.1). Is there some weird trick - remember I'm a newbie to Amigo and you might need to ***unfortunately*** spoonfeed stuff. How do I use ldconfig to fix whatever got broke to cause this error?

I#m not sure how you got that library in there...
Amigo-2.0 doesn't come with GTK2 installed.
Install these pkgs (minimum)
glib2
gtk+-2
atk
pango

For firefox you need to install the other X-11 font packages. Gaim may require some extra libs also, like the esd sound daemon package, or others.

About ldconfig: this is run automatically each time you boot, but you should run it manually after installing any new libraries, so they get found. What ldconfig does is scan 'trusted' library directories, like /usr/lib and consults the file /etc/ldso.conf which has a list of other library directories. All this info goes into the ldconfig cache, so that when a program calls for a library, 'ld' -the dynamic linker, consults the cache to see if the library is present on the system.

'ld' has another handy feature: 'ldd' which will test a binary to see which libs it needs, and tell you if they are present or not. You can use this like this:
Install your desired program, then run 'pkgtool' in an xterm and choose 'View list of files' and then choose the package you just installed. Scroll down through the list of installed files -look for the main executable, usually in /usr/bin/. This is mainly to know what the programs real name is, like mozilla-firefox.
Anyway, once you know the name, browse to that directory:
cd /usr/bin
and type:
ldd mozilla-firefox

You'll see a list of required libs for that binary- If any are missing it will say 'not found'.

Because of size considerations GTK2 was left out of Amigo-2.0. Search this forum for more discussion of libs and fonts for firefox, and on getting GTK2 programs working.
