Hi, Markus.

You should be able to run Qt Jambi against any Qt distribution as long 
as the versions match and Qt Jambi is built from source against the 
actual configuration of Qt against which you are running it.

However, one problem I do foresee, is that there is a bug in the JVM 
causing it to crash at random when running with code that uses SSE or 
MMX instructions. Therefore, to protect yourself against these crashes, 
the Qt version against which you run Qt Jambi should be configured with 
the options:

    -no-mmx -no-sse -no-sse2 -no-3dnow

As far as we know, this is a problem exclusive to Sun's Virtual Machine 
version 1.5, so hopefully it should not occur if you use any other 
implementation.
