Non-batch mode of compiled code

Thanks. But I didn’t really mean that.

Just find the solution:

Switching off batch mode does not work?!

Hi, I am running a C++ program within a large framework. This framework calls my code, but I have no access to whatever happens outside of my own code. I link ROOT libraries into my code. I try to open a canvas. First, this didn’t work because ROOT was set to batch mode (gROOT->IsBatch()==kTrue). But even if I call gROOT->SetBatch(kFalse) before I try to open the canvas, it does not work - although at least something is different: now I get the following two messages: Warning in TCanvas::Res…

I need to create TApplication object first.
