caffe

I got this error for caffe build. How can I fix it? I'm using Mac OSX Yosemite 10.10.1.

It seems I have correct libraries. (Is this right thing to check??)

OpenCV libraries seem to be built with libstdc++, because the official install guide suggests so.

All the build commands are correctly with -stdlib=libstdc++ option.

Machida-no-MacBook-Air:caffe machidahiroaki$ make -n | grep clang | grep -v stdlib=libstdc++

Thank for your help in advance!

Now I find I can use ld with -v option. I keep investigating.

Found a nice option for ld, which logs each file the ld loads.

Solved!

cv::imread(cv::String const&, int) is defined on libopencv_imgcodecs.dylib and Makefile is missing it.

So, I added opencv_imgcodecs to Makefile.

LIBRARIES += glog gflags protobuf leveldb snappy \
        lmdb \
        boost_system \
        hdf5_hl hdf5 \
        opencv_imgcodecs opencv_highgui opencv_imgproc opencv_core pthread
