[Qt-interest] "not of required architecture" error message on my own static library

[Warren]

Thanks for the reply but I don't understand why the two projects are  
compiling to different architectures.  What is it in the .PRO files  
that I have set up wrong?  They are very basic projects at the moment  
(I'm just trying to learn QT at the moment).
