I see two bugs in the extension checking code. I'll push a fix
onto gerrit today.<br>
<br>
It doesn't explain why LoadOpenGLExt test segv's. Any chance you
could share a stack trace?<br>

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>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

<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>

<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
moz-do-not-send="true"
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>

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>
