[Hong Cheng]

Hi, I'm new to the group. Not sure if this is the right forum to ask such questions, so please kindly let me know if I should post such questions somewhere else.

My OS is ubuntu14.04LTS.

Caffe sets is BLAS=mkl,oprncv=3.2.0,support Anaconda3.6, cudnn5.1.10,cuda8.0.61

the problem is when I try to "make all" in "caffe"direction,this error happens.

cine@CINe:~/caffe$ make all
CXX/LD -o .build_release/tools/extract_features.bin
.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&)'
.build_release/lib/libcaffe.so: undefined reference to `cv::imdecode(cv::_InputArray const&, int)'
collect2: error: ld returned 1 exit status
make: *** [.build_release/tools/extract_features.bin] Error 1

Anyone can help me?

Thanks in advance！！！
