Thank you @wadefelix it worked out!

I also needed to add --expt-relaxed-constexpr to nvcc, and then it worked out nicely

Here is my lib/make.sh for other who encounter the same issue.

P.S. i forgot to mention, that i use CUDA toolkit 8.0 and CuDNN v5, nvidia quadro K620 GPU - 2GB

if [ -d "$CUDA_PATH" ]; then nvcc -std=c++11 -c -o roi_pooling_op.cu.o roi_pooling_op_gpu.cu.cc \ -I $TF_INC -D GOOGLE_CUDA=1 -x cu -Xcompiler -fPIC $CXXFLAGS \ -arch=sm_37 --expt-relaxed-constexpr
g++ -std=c++11 -shared -D_GLIBCXX_USE_CXX11_ABI=0 -o roi_pooling.so roi_pooling_op.cc \ roi_pooling_op.cu.o -I $TF_INC -D GOOGLE_CUDA=1 -fPIC $CXXFLAGS \ -lcudart -L $CUDA_PATH/lib64
