Hello Vassili,
What you did should be correct. However I have to admit I never tried to
do what you did, namely to compile and run "guitest.C" against of Qt
layer.
I'll try to reproduce your problem (tonight) and let you know. I am away
at the moment.
Did you try to run guitest.C as a ROOT macro ? Did it work?
Thank you, Valeri
