I'm trying to compile a cpp file using mex (changeanalysis.cpp). I have Matlab R2012a, Xcode 4.6 on a MAC OS X 10.7. In the file changeanalysis.cpp, aef_global_dllexport.h is included. Some part of aef_global_dllexport.h is as follows:

    ////////////////////////
    // DLL EXPORT FUNCTIONS
    ////////////////////////
    #define DLLEXPORT _declspec(dllexport)
    DLLEXPORT double maha_dist_3D_ex(   double          x,
                                        double          y,
                                        double          z,
                                        double*         mean,
                                        double**        icovm);
    DLLEXPORT int matrix_inv_ND_ex(     double**        matND,
                                        double&         det,
                                        int             Dim);
    DLLEXPORT int matrix_copy3x3_ex(    double**        x, 
                                        double**        y);
    .
    .
    .
When I compile the file changeanalysis.cpp, I get the following error message at the command prompt:

mex -I"/Users/marzi/Documents/MATLAB" changeanalysis.cpp

In file included from changeanalysis.cpp:58:

mex: compile of ' "changeanalysis.cpp"' failed.

Error using mex (line 206) Unable to complete successfully.

Does anyone know how to fix this or what is the cause of this error?

Thanks.
