Hello, I trying to install OpenCV 3.3 on Ubuntu 16.04 with CUDA 9 and Caffe framework. I am following this guide: https://github.com/BVLC/caffe/wiki/OpenCV-3.3-Installation-Guide-on-Ubuntu-16.04 I already changed the FindCUDA.cmake and OpenCVDetectCUDA.cmake file according to CUDA9 requirement and finished building environment successfully by running: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D FORCE_VTK=ON -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_CUBLAS=ON -D CUDA_NVCC_FLAGS="-D_FORCE_INLINES --expt-relaxed-constexpr" -D WITH_GDAL=ON -D WITH_XINE=ON -D BUILD_EXAMPLES=ON .. However when i tried: make -j $(($(nproc) + 1)) it is giving me an error as follows: [ 44% ] Linking CXX shared library ../../lib/libopencv_cudawarping.so [ 44% ] Build target opencv_cudawarping Makefile:160: recipe for target 'all' failed make: * [all] Error 2 Please help me with this.
