Description Panos Kavalagios 2009-07-07 03:35:30 EDT
Description of problem: Error while loading liblwres.so.50

Version-Release number of selected component (if applicable): bind-libs-9.6.1-2.fc11.x86_64

How reproducible: Just run whatever bind util like "host" and "nslookup"

Steps to Reproduce:
1. Run host www.cnn.com
Actual results:
host www.cnn.com
host: error while loading shared libraries: liblwres.so.50: cannot open shared object file: No such file or directory

Expected results: IP resolving of www.cnn.com

Additional info: The link of shared library is broken:
ls -al /usr/lib64/liblwres*
lrwxrwxrwx 1 root root    18 2009-07-06 08:55 /usr/lib64/liblwres.so.50 -> liblwres.so.50.2.0
-rwxr-xr-x 1 root root 73336 2009-06-24 17:58 /usr/lib64/liblwres.so.50.0.2
It should have pointed to liblwres.so.50.0.2 and not to liblwres.so.50.2.0. A workaround would be possibly to manually fix the link.
Comment 1 Jon Baker 2009-07-07 10:05:22 EDT
Manually fixing the link does indeed correct the problem.  There is a second one that needs fixing, libbind9.so.50 -> libbind9.so.50.2.0 should be libbind9.so.50 -> libbind9.so.50.0.3

This appears to have been changed on my system with the latest updates of the bind packages.
Comment 2 Jon Baker 2009-07-07 10:23:27 EDT
Also, appears (for me) to only be effecting the 64-bit libraries, as my i386 box has the correct file that the link is linking to.
Comment 3 Stephen John Smoogen 2009-07-07 16:56:01 EDT
running ldconfig -v fixed both problems.
Comment 4 Panos Kavalagios 2009-07-08 00:55:56 EDT
Indeed, ldconfig can also help as an alternative workaround and only as that. The link was delivered by the bind-libs package:

$ rpm -qf /usr/lib64/liblwres.so.50

Either the package to include the correct link or to run ldconfig as post install procedure. In no case a user should be required to run additional programs or manually fix broken links.

Happening on 32-bit here.
