Support for OpenCV3 about deepdetect HOT 7 CLOSED

The problem is still persistent.

I am currently using Ubuntu 14.04, with openCV 3.0.0 and caffe 1.0.0r3

.build_release/lib/libcaffe.so: undefined reference to `cv::imread(cv::String const&, int)'
.build_release/lib/libcaffe.so: undefined reference to `cv::imencode(cv::String const&, cv::_InputArray const&, std::vector<unsigned char, std::allocator<unsigned char> >&, std::vector<int, std::allocator<int> > const&)'

Looks like a problem with OpenCV 3, can you use 2.x by any chance ? I've seen many reports of difficulties with OpenCV 3 and Caffe as well.

That said, if you are willing to test on something and see whether it clears your issue, can you try to add opencv_imgcodecs to main/CMakeLists.txt so the last line looks like:

target_link_libraries (dede ddetect glog gflags opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs cppnetlib-uri curlpp curl crypto ssl ${Boost_LIBRARIES} ${CAFFE_LIB_DEPS})

This is similar to the changes reported in https://github.com/BVLC/caffe/pull/3186/files

Let me know how compilation goes after this change.

For me works! Add only target_link_libraries(fisherfaces ${the_library} opencv_core opencv_imgproc opencv_highgui opencv_imgcodecs)

Thanks, could you share the exact diff to the existing code?

We will escalate this one as OpenCV 3 needs to supported in a near future.

PR #125 has been tested, and should be merged soon, cc @iamgroot42 if you are willing to give it a try.
