Invalid Mex File Error on MAC OS Yosemite

I am receiving Invalid MEX file error. Symbol Not Found.

The operating system is MAC OS X Yosemite and the MATLAB version is R2014a.

Here is the received error:

Invalid MEX-file '/Users/ozge/Documents/BO-project/BSR_mac/grouping/lib/buildW.mexmaci64':
dlopen(/Users/ozge/Documents/BO-project/BSR_mac/grouping/lib/buildW.mexmaci64, 6): Symbol
not found: __ZNKSt5ctypeIcE13_M_widen_initEv
  Referenced from: /Users/ozge/Documents/BO-project/BSR_mac/grouping/lib/buildW.mexmaci64
  Expected in: /usr/lib/libstdc++.6.dylib
 in /Users/ozge/Documents/BO-project/BSR_mac/grouping/lib/buildW.mexmaci64

How can I fix this problem? Thanks in advance.

Did you build buildW.maxi64 yourself, or did you download it from somewhere (I'm guessing the latter)?

I Google searched "__ZNKSt5ctypeIcE13_M_widen_initEv" and there are lots of hits from a variety of software packages. This file might need to be rebuilt using a Xcode/OSX configuration closer to your own.
