Roofit and RooStats

Hello everybody,

I am using Root 5.22/00 und Win2k, compiled with VC++ 8.0

After

root [0] TH1F hist("hist","Histo1",100,0,4.4) root [1] hist.FillRandom("gaus",10000) root [2] hist.Draw()
I use the histograms context menu to open the FitPanel. Then I get this error message:

an Root crashes.

Can someone help?

Greetings,
Axel

Hi,

We don’t have neither win2k nor MSVC++8.0. But we’ll try to reproduce the problem and let you know.
BTW, in the meanwhile, could you try to catch the exception in the debugger? (if you compiled ROOT in debug mode…)

Cheers,
Bertrand.

Hi,

TGuiBuilder does also not work.

I compiled Root with qt-enabled and somewhere there are these gui options set to “qt” and “qtgui” instead of “native” or so. Can that be the reason?

How do I enter the debugger (from the command prompt)?

Thanks,
Axel

Hi,

First of all, QtROOT is not supported on Windows, unless you download the version from BNL…
So please, put back “native” value to Gui.Backend and Gui.Factory options and try again.

Then, here is an example how to start the debugger from the command line:
devenv /debugexe root.exe

Cheers,
Bertrand.
