matcaffe throws block of errors when trying to run code.

[tkasarla]

I am on a shared cluster and not a root user.

While doing make matcaffe, I encountered a warning

Warning: You are using gcc version "5.4.0".  The version
         currently supported with MEX is "4.4.x".
         For a list of currently supported compilers see: 
         http://www.mathworks.com/support/compilers/current_release/

Since it was only a warning, I ignored it.

I added caffe path to matlab by addpath('/path/to/caffe/matlab')

I got the following error while trying to execute this line caffe.reset_all();

/usr/local/MATLAB/R2013a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by
/users/tejaswi.k/caffe_path/caffe/matlab/+caffe/private/caffe_.mexa64)

From https://github.com/BVLC/caffe/issues/827, I added this to .bashrc: export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

And now, if I try to run caffe.reset_all(); I get another error as below

/users/tejaswi.k/caffe_path/caffe/matlab/+caffe/private/caffe_.mexa64: undefined symbol:
_ZN2cv8imencodeERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEERKNS_11_InputArrayERSt6vectorIhSaIhEERKSB_IiSaIiEE

From https://github.com/BVLC/caffe/issues/3934, I understood that it is issue with the caffe being built from system's opencv and matlab having its own opencv libraries.

There they suggested to change symbolic links in /bin/glnxa64, but since I am not a root user on the shared cluster, cannot change the symbolic links in /bin/glnxa64 .

I instead added following to .bashrc :

export LD_PRELOAD = /usr/lib/x86_64-linux-gnu/libopencv_[core,highgui,imgproc]

Now, it also requires libtiff.so.5 location for the /usr/lib of image processing libraries, so I added that too.

Doing this throws more errors and matlab force closes.

The errors are given below:
