Hi there,
My System environment is Ubuntu 16.04
, and I installed vtk via pip install vtk
If I set
export LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libGLEW.so
then every time when I use vtk
in python the program will crash, and prompted Segmentation fault (core dumped)
.
For example, the following python scripts will reproduce the crash.
#!/usr/bin/env python
#
import vtk
import time
cone = vtk.vtkConeSource()
cone.SetHeight(3.0)
cone.SetRadius(1.0)
cone.SetResolution(10)
coneMapper = vtk.vtkPolyDataMapper()
coneMapper.SetInputConnection(cone.GetOutputPort())
coneActor = vtk.vtkActor()
coneActor.SetMapper(coneMapper)
ren = vtk.vtkRenderer()
ren.AddActor(coneActor)
ren.SetBackground(0.1, 0.2, 0.4)
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)
renWin.SetSize(500, 500)
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)
for i in range(0, 180):
time.sleep(0.01)
renWin.Render()
ren.GetActiveCamera().Azimuth(1)
iren.Start()
However if I do NOT set the variable LD_PRELOAD
with libGLEW.so
, everything works well.
I was wondering how to resolve this issue, coz I do not want to manually cancel the LD_PRELOAD
variable every time before using vtk
.
Thanks in advance.
