Updated libpng, now existing GTK prog won't start anymore - Rh9


Hi guys,

I downloaded and installed libpng-1.2.8.tar.bz2 from the GTK site's dependencies directory in preparation for a an upgrade of my GTK library.

I now have the problem on my Rh9 system that some GTK programs don't want to
start. GFTP fails currently, and the error is

gftp-gtk: relocation error: /usr/local/lib/libpng12.so.0: undefined symbol: inflateInit_

Is there any way I can force GFTP to find my old libpng dynamic libraries? Where they even preserved when I put the new libpng in? I thought that when a library is upgraded, the original files are still there, only not symlinked.

Or has it something to do with ldconfig?

How can I get my existing GTK programs to run with the "new" libpng? (I haven't even upgraded GTK itself yet - still on the old version with which GFTP worked fine...)

Any help appreciated!

I got this fixed myself. My /usr/local/lib directory looked like this:

rw-r--r-- 1 root root 199708 May 12 14:22 libpng12.a
lrwxrwxrwx 1 root root 13 May 12 14:22 libpng12.so -> libpng12.so.0
lrwxrwxrwx 1 root root 19 May 12 14:22 libpng12.so.0 -> libpng12.so.0.1.2.8
-rwxr-xr-x 1 root root 186411 May 12 14:22 libpng12.so.0.1.2.8
lrwxrwxrwx 1 root root 10 May 12 14:22 libpng.a -> libpng12.a
lrwxrwxrwx 1 root root 11 May 12 14:22 libpng.so -> libpng.so.3
lrwxrwxrwx 1 root root 17 May 12 14:22 libpng.so.3 -> libpng.so.3.1.2.8
-rwxr-xr-x 1 root root 186411 May 12 14:22 libpng.so.3.1.2.8

and what I did to fix it was to delete the libpng12.so symlink as well as the libpmg12.so.0 symlink.

Thereafter, my old GTK based programs started up again!

Any idea why? It works now but I have that sinking feeling when something was too easy...
