Compiling your code I see the following :

$ mkoctfile -mex mexADIconf.c 
mexADIconf.c:37:10: warning: non-portable path to file '<Matrix.h>'; specified 
path differs in case from file name on disk

The first message is just a warning as on macos files are not case sensitive 
the same would be an error on Linux.
The second one is because you are including directly matrix.h from liboctave 
which includes cassert which is C++.

Just comment out the unnecessary includes and all should work:

/* header */
#include <mex.h>
//#include <matrix.h>
//#include <stdlib.h>
//#include <math.h>


HTH,
