Issue summary

Steps to reproduce

If you are having difficulty building Caffe or training a model, please ask the caffe-users mailing list. If you are reporting a build error that seems to be due to a bug in Caffe, please attach your build configuration (either Makefile.config or CMakeCache.txt) and the output of the make (or cmake) command.

I am trying to build this using cmake and I have installed opencv 3.1.0 in my .local directory. I have given the OpenCV_DIR in Cmakelist as follows:

set(OpenCV_INCLUDE_DIRS "/home/bramin/.local/lib/opencv/include") set(OpenCV_LIBS "/home/bramin/.local/lib/opencv/lib/libopencv_core.so") set(OpenCV_CONFIG_PATH "/home/bramin/.local/lib/opencv/lib/pkgconfig/opencv.pc")

---[ OpenCV

if(USE_OPENCV) set(OpenCV_DIR "/home/bramin/.local/lib/opencv/") include_directories(SYSTEM ${OpenCV_INCLUDE_DIRS}) list(APPEND Caffe_LINKER_LIBS ${OpenCV_LIBS}) message(STATUS "OpenCV found (${OpenCV_CONFIG_PATH})") add_definitions(-DUSE_OPENCV) endif()

But while doing make all I am getting following errors: [ 97%] [ 98%] Building CXX object tools/CMakeFiles/extract_features.dir/extract_features.cpp.o Building CXX object tools/CMakeFiles/device_query.dir/device_query.cpp.o Linking CXX executable cifar10/convert_cifar_data Linking CXX executable device_query Linking CXX executable siamese/convert_mnist_siamese_data Linking CXX executable mnist/convert_mnist_data ../lib/libcaffe.so.1.0.0-rc3: undefined reference to cv::imread(cv::String const&, int)' ../lib/libcaffe.so.1.0.0-rc3: undefined reference tocv::imencode(cv::String const&, cv::_InputArray const&, std::vector<unsigned char, std::allocator >&, std::vector<int, std::allocator > const&)' ../lib/libcaffe.so.1.0.0-rc3: undefined reference to cv::imdecode(cv::_InputArray const&, int)' ../lib/libcaffe.so.1.0.0-rc3: undefined reference tocv::resize(cv::_InputArray const&, cv::OutputArray const&, cv::Size, double, double, int)' collect2: error: ld returned 1 exit status make[2]: [examples/cifar10/convert_cifar_data] Error 1 make[1]: [examples/CMakeFiles/convert_cifar_data.dir/all] Error 2 make[1]: Waiting for unfinished jobs....
