hi,@ankurhanda , The following is the output after command "luarocks make gvnn-scm-1.rockspec" cmake -E make_directory build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/hpj/torch/install/bin/.." -DCMAKE_INSTALL_PREFIX="/home/hpj/torch/install/lib/luarocks/rocks/gvnn/scm-1" && make

hi!@ankurhanda I add that flag to my CMakeLists.txt it fixed the problem and compiles fine. ie. Add this near the front: set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} \"-D_FORCE_INLINES\" ") thank you!
