Perhaps you've linked libraries from multiple drivers? I've seen
this test segv when two GL libs are mixed, the render context is
invalid and glGetString returns NULL. In that case it's not a bug
in VTK but rather a build issue since you should only be using a
single OpenGL library.<br>
<br>
Could you report the output of<br>
<br>
grep ^OPENGL_ CMakeCache.txt<br>
<br>
If you haven't already rm your build re-configure and re make. you
should do this after any changes to the open gl drivers.<div><div class="h5"><br>

<div>Jose, <br>
<br>
with all of your driver woes I think it's likely that
you're unintentionally using Ubuntu's Mesa libGL rather
than NVIDIA's. At least this will explain the error
report below.<br>
<br>
Mesa, depending on release version and renderer, has
some bugs that prevent this class from working correctly
and some or all of the vtkOpenGLGPUVolumeRayCastMapper
ctests fail. That's why the class has been disabled if
the driver is Mesa.<br>
<br>
To confirm which driver you're using include the output
from<br>
<br>
ctest -R LoadOpenGLExt --verbose<br>
<br>
Please include this in your bug report.<span><font color="#888888"><br>

<div>I finally installed and uninstall
nvidia drivers and xorg and nothing
worked. Then I realized that the
conflicting file
Rendering/volumeopengl/vtkopenglgpuvolumeraycasmapper.cxx
was modified 8 days ago. I switched back
from head to v.6.0.0 and it worked again.<br>

I don't know how to report bugs the

<div>Hi, I know this is not
exactly vtk but I hope you
can get my opengl error. I
made a mistake updating a
driver and now I have no
idea how to solve it. <br>
</div>
I got interested in trying
itk filters solved through
gpu, so I installed CUDA
following this link:<br>
<a href="http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html#package-manager-installation" target="_blank">http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux/index.html#package-manager-installation</a><br>
</div>
Then I realized they were
useless so I built a new set
of vtk6.1+itk4.5+qt4.8.5. The
problem is that my old files
compiled with
vtk6.1+itk4.5+qt4.8.4 don't
work anymore. Specifically I
had a volume rendered with
vtkGPUVolumeRayCastMapper and
now it shows an error <br>
<p style="margin:0px;text-indent:0px"><span style="font-family:'Monospace';font-size:9pt;color:rgb(190,20,20)">ERROR:

I have installed-uninstalled
nvidia drivers many times but
I have no clue on what is
going on. Seems that it
changed
/usr/local/x86.../libGL.so and
libGLU.so <br>
</div>
I am using ubuntu 12.4, my
graphics card is nvidia geforce
9800 and qt 4.8.5<br>
