Thanks a lot to all of you, your advice has been very helpful. I have
now installed QT 4.5.1 MinGW on my machine and the QtAda programs work
fine, which is what I wanted.
I don't remember seeing any mention of this fact on the QtAda website,
it might be something interesting to add a note on this.
May thanks!
Best regards, Alexis.
