Makefile 安装caffe时找不到-lopencv_imgcodecs和-lopencv_videoio

我在Ubuntu 16.04上安装带有opencv3.0+和CUDA的Caffe时遇到了问题

我还将opencv_imgcodecs和opencv_videoio添加到我的Makefile中，但这并不能解决问题

我在Caffe用户组中检查了几个答案，但没有答案可以解决我的问题

我的错误消息：

nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).
AR -o .build_release/lib/libcaffe.a

我在Makefile中的设置

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5 opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs opencv_videoio

我的imgcodecs和videoio在~/miniconda2/envs/frcnn/include/opencv2下/

在此处，我修改了有关Miniconda虚拟环境的Makfile.config：

 ANACONDA_HOME := $(HOME)/miniconda2
 PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
             $(ANACONDA_HOME)/include/python2.7 \
             $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include \


INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial /home/pohsuan/miniconda2/envs/fastrcnn/include

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial /home/pohsuan/miniconda2/fastrcnn/lib

也许取消注释

 OPENCV_VERSION := 3 

在第21行，如果你还没有。 更糟糕的情况是，卸载OpenCV并安装低于3的版本

我为此做了很多努力，最后决定使用OpenCV 2.4.9.1，它成功了

系统上的opencv\u imgcodecs和opencv\u videoio文件在哪里？您是如何安装opencv 3的？你试过吗？
