libmatio.so.2: cannot open shared object file

[mjohn123]

I downloaded and install matio by following commands:

./configure
make
sudo make install

I also changed the MATLAB_DIR := /usr/local/MATLAB/R2014b in Makefile.config file. Then I compile the PSPnet using

make -j8 && make matcaffe

I got the success message

MEX matlab/+caffe/private/caffe_.cpp
Building with 'g++'.
Warning: You are using gcc version '5.4.1'. The version of gcc is not supported. The version currently supported with MEX is '4.7.x'. For a list of currently supported compilers see: http://www.mathworks.com/support/compilers/current_release.
MEX completed successfully.

However, when I run the eval_all.m file, I got the error

Invalid MEX-file '/home/john/PSPNet/matlab/+caffe/private/caffe_.mexa64': libmatio.so.2: cannot open shared object file: No such file or directory
Error in caffe.reset_all (line 5)

```

How can I fix it? Thank you

Oh.
After "make install" matio, try "sudo ldconfig".
Then comeback and build caffe again.
