Re: need help w/ ld.so.conf.d entries

On CentOS 5.4, because I am trying to either compile or install rpm
forms of a number of different video processing tools, I am meeting
problems with the Qt libraries and need some help please in placing
them all in the ld.so.conf.d directory such that they're all available
to the necessary application(s).

The programs include e.g. Myth-TV 0.22, qdvdauthor 2.0.0, qlscribe
from "Lightscribe". They seem to need different versions of the Qt
libraries, but having them all in ld.so.conf.d is causing problems
such as "Symbol
_xxx not found". These problems don't occur after "ldconfig" when
only the correct *.conf is/are in ld.so.conf.d.

$ ls /etc/ld.so.conf.d | sort
BerkeleyDB.conf
kernelcap-2.6.18-128.el5.conf
kernelcap-2.6.18-164.2.1.el5.conf
kernelcap-2.6.18-164.6.1.el5.conf
kernelcap-2.6.18-164.el5.conf
local.conf
mysql-i386.conf
nvidia.conf
qt4-i386.conf
qt-i386.conf
wine-i386.conf

I've been saving the various Qt .conf files one level up and cp'ing
them as needed prior to an ldconfig:

$ ls /etc/*.ORG | sort
/etc/qt435-i386.conf.ORG
/etc/qt44-i386.conf.ORG
/etc/qt4-i386.conf.ORG
/etc/qt-i386.conf.ORG

but this causes painful problems, certainly of my own making.

What is the correct way to handle this issue please?

What is the exact output when running ldconfig verbosely, and what is
the exact contend of the QT .conf files themselves? If it's erroring
when you include the qt config files, it'll likely be those config file
contents.
