I just joined a project that embeds a perl interpreter and exposes a lot of its base functionality to the perl for extensions. The project currently uses KDE and QT3. I am trying to remove the need for KDE so that we can move on to QT4. Loading our dynamic library for perl extensions works perfectly in KDE. I am trying to replace the KDE library loader with the QT loader and have run into some problems that you might be able to shed some light on for me.

When using the QT library loader when our underlying perl script runs I get the following errors. 

Can't load '/usr/lib/perl5/5.8.7/i686-linux/auto/IO/IO.so' for module 
+IO:

The final reference in the dump, battlerecorder.pl starts the interaction with our C++ code. My colleague on this project thinks the problem is because the QTLibrary loader does not expose the global namespace (I am not sure exactly what that means).

Anyway, I am good in Perl itself, but am a little challenged on this problem any information you could provide for me I would appreciate.

Thanx

Julian
