upgrade gtk+2 went wrong

potuz · 12-26-2009, 12:48 AM

Hello there, I upgraded from gtk+2.16.0 to 2.19.2 without using a
package manager (compiled, removed by hand the old libraries and
installed on top of the same prefix). Things went wrong at some point
but I'm not sure where. I get plenty of errors of the form

... does not export GTK+ IM module API .... invalid ELF header

for example when running perl I'd get these errors. I can't recompile
either the previous version of gtk+2 cause of these errors and I can't
even compile 2.19.2 again because of these errors.

Looking at my /usr/bin/gdk-pixbuf-query-loaders I see that the binaries
are the old ones, so I'm not sure why they didn't get overwritten by the
new ones (the libraries are all new). I'm not sure where did I screw
things up but I'd love to hear any help from you guys.

Thanks,

R.

Ubuntu 9.04 Jaunty : version 2.16.1 ( libgtk2.0-0 ).

Changing gtk+2.xx is not really an upgrade, more like ..
..Trash-600-libraries-and-GUI-applications-depending-
-on-2.16.x .

If you change it, you will usually also have to
recompile all those 600 programs.

It is no problem having extra glib2 / gtk+2, but it
is recommended to use a "hideaway location" like e.g.
/usr/local/glib222/ ( --prefix=/usr/local/glib222/ ).

I don't know of any easy solution, may be ..
sudo apt-get install libgtk2.0-0 will recover things.
If the terminal works.

Else suggest : Shut down and boot into your computer
from the live Ubuntu cd, and edit your
/etc/X11/default-display-manager : change the line
/usr/bin/gdm to : false .
That makes it possible to boot into your Ubuntu,
to CLI, and : cd gtk-2.19.2/ and do this ..
sudo make uninstall
.. Next : sudo apt-get install libgtk2.0-0
.. And .. startx , to log into X.
.....

Hi and thanks for the answer, but I'm not running Ubuntu nor any distribution with a package manager. My Gnome is still mostly functional, and I am posting from Firefox actually. The things that fail are subtle: some python modules, perl, intltool and such. I am not really sure what's failing and what's not. I still have the old libraries floating around, so I could probably change the simlinks by hand to point to the old ones, but I'm not sure if that will solve the problem. If I could compile the old gtk+2 that will be great.

Just to post a little more info, if I run python or perl for example they spit out the GTL+ input method module file, something like

Code:

# GTK+ Input Method Modules file
# Automatically generated file, do not edit
# Created by python from gtk+-2.19.2
#
...
...

If I run something like python --help, then I get

Code:

# GTK+ Input Method Modules file
# Automatically generated file, do not edit
# Created by python from gtk+-2.19.2
#
Cannot load module /home/heluani/Downloads/--help: /home/heluani/Downloads/--help.so: cannot open shared object file: No such file or directory
/home/heluani/Downloads/--help does not export GTK+ IM module API: /home/heluani/Downloads/--help.so: cannot open shared object file: No such file or directory

If I run some python module I get the "wrong ELF" error, something like

Code:

heluani:~/Downloads $denyhosts.py 
# GTK+ Input Method Modules file
# Automatically generated file, do not edit
# Created by /usr/bin/python from gtk+-2.19.2
#
Cannot load module /usr/bin/denyhosts.py: /usr/bin/denyhosts.py: invalid ELF header
/usr/bin/denyhosts.py does not export GTK+ IM module API: /usr/bin/denyhosts.py: invalid ELF header
