Hi Conan, my first guess is, that the Cmake-Scripts did not find Cuda on your system. Cuda 4.0 is not a problem in general. Thus try to build osgCompute again from scratch and take a look at the advanced variable "CUDA_RUNTIME_LIBRARY". If it is not available correctly you will have to set it manually to your cudart-library (this may be the case on 64-Bit machines since we still have to adapt the FindCuda script for Cmake).
