make mattest error despite succesfull make matcaffe

[Richardo Tiono]

Hello I just recently tried to install matcaffe for my research project and I have encountered some problem during make mattest. I am currently following installation tutorial

I have 2 different set of problem which depends on whether I input this command on terminal or not

Here is the command I input based (this is based on tutorial)

export LD_LIBRARY_PATH=/opt/intel/mkl/lib/intel64:/usr/local/cuda/lib64 
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6

Here is the output of the error if I input those command :

Invalid MEX-file '/home/cgal/caffe/matlab/+caffe/private/caffe_.mexa64':
/usr/lib/libgdal.so.20: symbol TIFFReadRGBATileExt version LIBTIFF_4.0 not
defined in file libtiff.so.5 with link time reference

Error in caffe.set_mode_cpu (line 5)
caffe_('set_mode_cpu');

Here is the output of the error if I dont use those command :

Invalid MEX-file '/home/cgal/caffe/matlab/+caffe/private/caffe_.mexa64':
/usr/local/MATLAB/R2015a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6:
version `CXXABI_1.3.8' not found (required by
/home/cgal/caffe/matlab/+caffe/private/caffe_.mexa64)

Error in caffe.set_mode_cpu (line 5)
caffe_('set_mode_cpu');

Here is the specification of my machine :

- Ubuntu 18.04

- 16gb ram

- i7 3770

- gtx 1080ti

- python 3.6

- gcc and g++ 6.5 (there is a warning during make matcaffe to use 4.7 but I cant find any g++ 4.7 therefore I tried to use gcc g++ 4.8.5 but the problem still the same)

Please help me resolve this. In case if you need more info I will update the post. Thank you

So I actually found the answer for this problem from this 2 post 1 and 2

1. Renaming the libstdc++.so.6 library file so that MATLAB cannot find it and is forced to use the system's version of the library. This file is located inmatlabroot/sys/os/glnxa64 . Renaming it to libstdc++.so.6.old should suffice. (where "matlabroot" is root installation directory of MATLAB)
2. inputting this command on terminal export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libtiff.so.5:/usr/lib/x86_64-linux-gnu/libstdc++.so.6
