After a long hiatus, I’ve recently started picking up VTK, and WOW, so much progress and new features to play around with. Kudos to all involved!
On to the question…
I have been evaluating language support of various features of VTK and ran into some issues with raytracing support via OSPRay.
I was able to build and run the examples in C++.
I then transitioned to prototyping in python and that worked pretty flawlessly.
Next, trying jvm support and I ran into an issue compiling VTK with OSPRay with java wrappings enabled.
I’m compling with jdk 8 but the source target still seems to be 1.7. There are a few warnings during the build about that but the main error is with linking the
vtkOSPRayMaterialLibaryJava…I get the following error:
➜ make -j8 | grep Error Undefined symbols for architecture x86_64: _vtkObject_Typecast, referenced from: _vtkOSPRayMaterialLibrary_Typecast in vtkOSPRayMaterialLibraryJava.cxx.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [lib/java/vtk-Darwin-x86_64/libvtkRenderingRayTracingJava.jnilib] Error 1 make: *** [Wrapping/Java/CMakeFiles/vtkRenderingRayTracingJava.dir/all] Error 2 make: *** Waiting for unfinished jobs.... make: *** [all] Error 2
Has anyone been able to successfully compile VTK with OSPRay + Java wrappers enabled?
