配置matcaffe 遇到的两个坑

1. 问题

（1) Invalid MEX-file '/root/caffe/matlab/+caffe/private/caffe_.mexa64': /matlab/r2016a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /root/caffe/matlab/+caffe/private/caffe_.mexa64)

（2) 

undefined

symbol:

_ZN2cv8imencodeERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEERKNS_11_InputArrayERSt6vectorIhSaIhEERKSB_IiSaIiEE

 

2. 解决方法

（1) export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

（2) 进入matlab的安装目录``，修改了如下软链接，问题解决

 

libbopencv_core.so.2.4 -> /usr/lib/x86_64-linux-gnu/libopencv_core.so.2.4.9

libopencv_highgui.so.2.4 -> /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.9

libopencv_imgproc.so.2.4 -> /usr/lib/x86_64-linux-gnu/libopencv_imgproc.so.2.4.9
