#253: MATLAB bindings, when installed, do not work
 Reporter:  rcurtin  |        Owner:  rcurtin         
     Type:  defect   |       Status:  new             
 Priority:  major    |    Milestone:  mlpack 1.1.0    
Component:  mlpack   |     Keywords:  matlab, bindings
 Blocking:  252      |   Blocked By:                  
 As it stands now, when MATLAB bindings are installed into
 ${MATLAB_ROOT}/toolbox/mlpack and the MATLAB path is updated correctly, we
 still have a failure that has to do with LD_LIBRARY_PATH not being set

 >> emst(x)
 Invalid MEX-file '/opt/matlab/toolbox/mlpack/mex_emst.mexa64':
 /opt/matlab/bin/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found
 (required by /usr/lib/libmlpack.so.1)

 Error in emst (line 36)
   result = mex_emst(dataPoints', 1, parsed.leafSize);

 There are several potential existing solutions that all require user work
 (i.e. removing the MATLAB-provided system libraries because they are
 unnecessary; manually modifying LD_LIBRARY_PATH).  But there should be a
 way to do this without the user needing to bother with it.  Maybe manually
 setting an RPATH to /usr/lib/x86_64-linux-gnu (or whatever directories are
