I'm testing VTK 7.1(git) with OpenGL2 using Mesa 11.2.2 and it fails at
when rendering the structure.
The first error I got is:
ERROR: In vtkShaderProgram.cxx, line 370
vtkShaderProgram (0xa385610): Error: GL_EXT_gpu_shader4: required extension
is not supported.
Error: failed to preprocess the source.
This was solved by defining MESA_GL_VERSION_OVERRIDE = 3.2
After that VTK request GLSL at least 1.50 then variable
MESA_GL_VERSION_OVERRIDE is defined as 150
After that I got the following message:
Program received signal SIGSEGV, Segmentation fault.
0x00002aaaaf55181b in vtkShaderProgram::FindUniform(char const*) () at
772 if (name == NULL || !this->Linked)
Do you have any idea on how I could solve this crash?
