[Paraview] ParaViewWeb ./pvpython segmentation fault

[kai liu]

Utkarsh,


How do I attach the backtrace for the segfault? I am pretty new to the Linux as well. Do I just do

$: gdb pvpython
$: run
on Ubuntu terminal to backtrace? 

If that's not how we backtrace, can you please tell me how to do it? Thank you!

Kai L.

Kai,

Can you rebuilding with CMAKE_BUILD_TYPE set Debug and the attaching the backtrace for the segfault? It's unclear why ParaViewPython::Run() would segfault.

I also tested on 32-bit and 64-bit Windows machines, and they all work fine. I even tried to build an off-screen ParaView Web on my own system, it is still the same segmentation fault.
