NOTE: osg needs to link against the varrier and alioscopy libraries (Varrier and coInterleaver), thus it needs to be added to the linking operation.
Linking Varrier and Alioscopy libraries with OpenSceneGraph
- Step-1: Get the Varrier library (File:VarrierCombiner.tar), and the alioscopy library (File:CoInterleaver.tar), and compile them.
- Step-2: Add the corresponding CMake modules under the CMakeModules directory of OpenSceneGraph
- Step-3 : Replace OpenSceneGraph/CMakeLists.txt with file: File:CMakeLists.txt
- Step-4: Replace OpenSceneGraph/src/osgViewer/CMkakeLists.txt file with: File:OsgViewer-CMakeLists.txt
- Step-5: Define environment variables $VARRIER_LIBRARY and $INTERLEAVER_LIBRARY to point to where the corresponding libraries are.
Compiling the OpenSceneGraph Package should work now.
