Hi Hamish, Machine is hosted as a GPU cluster, NVIDIA 4.1 (OpenCL is there), Tesla GPU. Configure was with: --with-opencl --with-opencl-includes=/opt/cuda/include so all good, but the libs (will add that), but does not help the include not found (-I/usr/cuda/include in Makefile...), on this machine it is CL/opencl.h Will take all your suggestions and look into it, Thanks, Yann -- ---- _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
