EVE tutorial crashes in ROOT 6

marki · April 21, 2017, 5:55pm

I am trying to run calorimeter.C from the EVE tutorials directory. It works for ROOT 5, but not ROOT 6. The transcript:

This is on a RedHat Enterprise 7 machine, ROOT 6.08.00.

Apparently, the tutorials which only access geometry information are fine. There appears to be a problem with rendering other types of objects, like hit information, perhaps having something to do with using OpenGL and/or interaction with graphics drivers.

We are about to start a new event display project and want to use EVE, but also want to use ROOT 6. We are concerned that this problem may be fundamental and prevent progress.

Any guidance appreciated.

Hi,

Add the lines:

#include "TSystem.h"
#include "TEveCalo.h"
#include "TEveWindow.h"
#include "TEveManager.h"
#include "TEveBrowser.h"
#include "TEveProjectionAxes.h"
#include "TEveScene.h"
#include "TEveViewer.h"
#include "TEveTrans.h"
#include "TEveCaloLegoOverlay.h"
#include "TEveLegoEventHandler.h"
#include "TEveGedEditor.h"
#include "TEveJetCone.h"

#include "TGLWidget.h"
#include "TGLViewer.h"
#include "TGTab.h"

#include "TFile.h"
#include "TAxis.h"

at the beginning of calorimeters.C to solve the problem.

Cheers,
Philippe.

Getting similar errors. Here is the before vs. after diff of the macro:

Taking calorimeters.C from GitHub as a reference, the crash happens on line 133 inside MakeCaloLego

glv->AddOverlayElement(overlay);

on the line 97 first of void calorimeters()

lego = MakeCaloLego(data, slotRightBottom);

MakeCaloLego works by itself (if one comments everything below “first tab”). But it begins failing at some point. This is, actually, only one example of failing eve examples as Mark wrote above.

How we tested it:

ROOT 6.04.08 or master branch on github
Ubuntu 16.04, 14.10, CenOS 6, 7, Fedora 24.
For test purposes the example was converted to a standalone program. Here is the cmake file and calorimeters.cpp
