extension `GL_EXT_gpu_shader4' unsupported in fragment shader

[Mauro Ferraro]

Hi all,

I compiled the VMTK 1.3 on my Dell M4800 under debian (system at the bottom). When I launch the renderer I get the following error

Executing vmtksurfaceviewer ...
GL_Version: 2.1 Mesa 10.3.2
ERROR: In /usr/local/XThreeMesh/vmtk-build/VTK/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 545

Please update your OpenGL driver. If you are using Mesa please make sure you have version 10.6.5 or later and make sure your driver in Mesa supports OpenGL 3.2.

I am not an expert of OpenGL, which libraries do I need to install?

Thanks,
Mauro

Dear Mauro,

by default vmtk 1.3 is based on VTK 7 which uses OpenGL 2.1 that seems to be not supported by your graphic card/driver under that OS.

A possibile solution is to re-compile vmtk from source and forcing it to use VTK 6.3

Edit the SuperBuild.cmake file and set the flag VTK_GIT_TAG to v6.3.0 (now is v7.0.0)

Let me know if it will work.

Best Regards

Simone

Dear Mauro and all vmtk-users,

we've just added a new CMAKE variable in the main CMAKE file named VMTK_USE_VTK7 

Please update your source code and then try to set it to OFF ( default is ON )

Best regards,

Simone

Hi Simone,

I tried to install the official NVIDIA drivers instead to the nouveau distribution. When I launch vmtk I get the following error

It seems to be the same error another user signaled today.

Dear Mauro,

can you check your env variables?

Did you compile it from source or did you use the egg?

Best Regards

Simone

I am having a very similar issue. I compiled vmtk from source and have the latest nvidia drivers installed and what I believe is the correct OpenGL version. I messed with several of the CMake VTK build settings to no avail. I also ran glxinfo which lists GL_EXT_gpu_shader4. the output is attached.

Hi Simone,

I just started again from scratch and the source compiled. I also installed the latest proprietary NVIDIA drivers, but the error is still there. Moreover, when I compile using VTK 6.3 flag I have the following error

Hi all,

I found this discussion on VTK-Dev forum

http://vtk.1045678.n5.nabble.com/OpenGL2-Picking-problems-on-Linux-td5730284.html

It seems to be a known bug with Mesa on Linux. I think that we can only wait the release of the fix...

Best,

Mauro

[Mauro Ferraro]

Dear Kurt,


I saw your post on VT-users forum

http://vtk.1045678.n5.nabble.com/GL-EXT-gpu-shader4-unsupported-help-td5736435.html

Did you solve the problem? Actually, I have no idea where to start fixing....

Best,
Mauro

[Simone Manini]

Dear Mauro,

did you try to recompile vmtk following this suggestion?

I suspect you have selected OSMesa when building VTK (or your application was compiled to use OSMesa). Make sure any cmake OSMESA options in you VTK build are turned off. They may be advanced options.

Best Regards

Simone

[Mauro Ferraro]

Dear Simone,


Here attached the ccmake options for the VTK build. The only options that seems related to OSMesa is VTK_OPENGL_HAS_OSMESA (OFF by default). I will try to compile VTK separately and then VMTK using system VTK. In your opinion, change the VTK_RENDERING_BACKEND to OpenGL can be useful?

Best,
Mauro

[Mauro Ferraro]

Dear Simone,

I compiled VTK and VMTK separately and the renderer now works (just need to set correctly the environmental variables for VTK) However, I had to deactivate vtk_vmtk contribs because of the following compilation error

[ 97%] Building CXX object vtkVmtk/Contrib/CMakeFiles/vtkvmtkContrib.dir/vtkvmtkDolfinWriter2.cxx.o

               ^

how can I fix it and/or I can remove this specific contrib with no additional effort?

Best,
Mauro

[Simone Manini]

Dear Mauro, 

thank you for letting us know. We’ll fix it asap and we’ll add some CMake option in VMTK in order to compiling VTK under Linux without the Mesa. After that, we’ll also update the python egg file for Linux.

Regarding the error under vtkvtmtkDolfinWriter2, we’re currently looking into it.

Thank you 

Simone

Dear Mauro and all vmtk-users.

The develop version of vmtk on github has been fixed.

Now you can compile vmtk using OpenGL instead of OpenGL2, there’s a flag in the main CMake.

Moreover, the error under vtkvtmtkDolfinWriter2 has been fixed and now you are able to compile vmtk with contrib.

Binary files for linux and windows will come soon.

Best regards

Simone

[Petar Petrov]

This way you loose depth peeling support (nice transparent objects)
so OpneGL instead of OpenGL2 is not a solution !!!!!!!!!

[Luca Antiga]

We’ll check OpenGL2 with VTK7.1, hopefully we’ll re-enable OpenGL2 in the near future.

Best,

Luca
