Hello,
I'm working on a server-based VTK application that renders snapshots of
3D (STL meshes). We're working on 64-bit Fedora 15 but I can try out
another platform if necessary. The application works fine with an X11
DISPLAY using hardware GL but crashes when we try to use Mesa only. I
decided to go to the very basic VTK_OPENGL_HAS_OSMESA
OffScreenRendering.cxx example:
http://www.vtk.org/pipermail/vtkusers/2010-February/106222.html
So I've compiled Mesa-7.11.2 and VTK 5.8.0 and get the following
segfault, debug info from gdb:
Starting program: /home/machbuild/build/OffScreenRendering
[Thread debugging using libthread_db enabled]
Program received signal SIGSEGV, Segmentation fault.
vbo_exec_EvalCoord1fv (u=0x203) at vbo/vbo_exec_api.c:498
498 vbo_exec_EvalCoord1f( u[0] );
A search for that "vbo_exec_EvalCoord1fv" error led me to this 2010 thread
between VTK and Mesa developers, which ends with "I'll try name mangling
when I get to work" so I wonder if it got forgotten about:
http://lists.freedesktop.org/archives/mesa-dev/2010-August/001993.html
In the meantime, I built Mesa-7.6.1 and the OffScreenRendering example
works.
I'm building Mesa with just "make linux-x86-64" and VTK with the following:
cd VTK_Build/
cmake \
-D
OPENGL_INCLUDE_DIR:PATH=/home/machbuild/build/Mesa-7.11.2/include/ \
-D
OPENGL_gl_LIBRARY:FILEPATH=/home/machbuild/build/Mesa-7.11.2/lib64/libGL.so
\
-D
OPENGL_glu_LIBRARY:FILEPATH=/home/machbuild/build/Mesa-7.11.2/lib64/libGLU.so
\
-D VTK_OPENGL_HAS_OSMESA:BOOL=ON \
-D
OSMESA_INCLUDE_DIR:PATH=/home/machbuild/build/Mesa-7.11.2/include/ \
-D
OSMESA_LIBRARY:FILEPATH=/home/machbuild/build/Mesa-7.11.2/lib64/libOSMesa.so
\
../VTK
Any ideas?
Thanks,
Joshua
