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

Did you google it? BVLC/caffe#4046

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!
