seems to happen when

Canvas.Update()

is called within Bunch.py

How did you do the build? When I try to import xboa tests, I get error
because numpy isn't found in third_party/build/python ...

So I build it with numpy-1.5.1. There's now a build script for both numpy and xboa in third_party.

Oops, noticed numpy now!

Okay, looks like there is a problem with display in the ROOT
installation. I do at python command line:

import ROOT
c = ROOT.TCanvas('hello')
hist = ROOT.TH2D
hist.Draw()

and get the same error. In fact, get the same error in ROOT/cint. Will
investigate further.

If you add a 'test runner' or just some script that outputs the results of the scripts, I can add it to Hudson. If it spits out XML reports, those can be displayed.

• Bad QT install
• Bad ROOTSYS etc

Probably to do with the way root build happens, but not sure what has
broken it. I notice env.csh doesn't set ROOTSYS for example.

Ah.... I'll set $ROOTSYS then (I just manually looked for libraries) and retest.

I had been trying to avoid as many environmental variables as possible to make syncing bash and C shell scripts easier and just not pollute stuff.

But I need to just set it (and also check if it exists rather than forcing people to grab ROOT). Ill add an issue but it's a low priority at the moment (unless somebody else wants to do it?)

I just tried setting rootsys (to third_party/install and third_party/build/root_5.28.00) and it didn't help...

I just commit a patch that I think will fix it. Waiting for the nightlies to let me know. Main thing? I don't do make install with ROOT and just leave it in its build directory, then source that.

it's a little nasty though because you then need to setup your environment twice. ie. after you install ROOT, you need to restart bash so it sees root. I don't like the fix, but I can plot stuff at least for the moment.

If that's the issue, I'll add a test to catch this type of ROOT failure in the future.

reported ROOT bug, though think I fixed it here
