Crash in geometry drawing

[frmanso]

Hello,
the drawing of the geometry file (O2 and alidist up to date today, ubuntu14.04 LTS) is crashing using the standard drawing commands:

TGeoManager::Import("geofile_mft.root");
TGeoVolume *t = gGeoManager->GetVolume("MFT");
gGeoManager->SetVisLevel(10);
t->Draw("ogl");

The error message is:

root [0] .x drawGeometry.C

Thanks for the help.

I experienced something similar but was not able to look into details until now. Does this appear for both, TGeant3 and TGeant4? Because there might be some internal things going on with some pointers

Hello,
Since 3 of us are concerned by the same issue, it's not related to the local installation of the software.

[frmanso]

Hello,
Finally, I have found the solution. The issue was related to a bug of the version of root v6-12-04. One must use the v6-12-06, from https://root.cern.ch/content/release-61206 and the bug is explained on https://root.cern.ch/doc/v612/release-notes.html#release-6.1206 (root crashes when trying to start opengl viewer).
By default in the aliceO2 installation, the root v6-12-04 is used, it should be changed to the 06 release.
Thanks by advance, F. Manso.
