[IGSTK-Users] Error in Release mode, not in Debug mode

[Tamas Ungi]

Hi Patrick,

I turned off IGSTK_USE_SceneGraphVisualization in both IGSTK and
IGSTKSandbox, recompiled in Release mode along with my own code, and the
same problem appears to be happening. The program execution hangs at the
same line.
What should be the next step?

Thank you,
Tamas

Hi Tamas,

Looks like the event: transformEvent is being observed by
igstkSceneGraphVisualization utilities.

Can you try to turn off the option in your cmake and give it another try?
IGSTK_USE_SceneGraphVisualization

Seems like we are narrowing down the problem now.

Thank you,

Patrick
