Hi Simon,
Why are you doing:
gGuiFactory = (TGuiFactory *) gROOT->ProcessLineFast("new>
TSdaqGuiFactory();");
instead of
gGuiFactory = new TSdaqGuiFactory();
The first form requires your class TSdaqGuifactory to be known by CINT.
You must generate a dictionary (via rootcint).
Why do you need to develop a GuiFactory?
