standalone MATLAB program: retrieve path and filename

I am using MATLAB R2008b in Windows 7. The compiler is Lcc-win32 C 2.4.1. I tried to make an exe file from an m file which can retrieve its path and filename. A colleague gave me a C file (mlgetmodulefilename.c) and suggested me to use mcc -m XYZ.m mlgetmodulefilename.c to generate XYZ.exe

First, I got some errors regarding matlab.h. So I copied, pasted, and renamed mex.h to matlab.h. Then, I faced the following error and warning:

Warning: Name is nonexistent or not a directory: C:\Program Files\MATLAB\R2008b\toolbox\compiler\patch.
c:\users\user\appdata\local\temp\mbuild~1\mlgetmodulefilename.obj .text: undefined reference to '_mxCreateString'
Can anybody help me with this? Thank you.

mlgetmodulefilename.c

#include "matlab.h"
#include <stdio.h>
#include <windows.h>
#include "megetmodulefilename_external.h"

/*
   INPUT
   None

     OUTPUT
     None

     RETURN
     The full filename of the calling function

     SYNOPSIS

*/
#define BUFSIZE 255

mxArray * Mmegetmodulefilename(int nargout_)
{
    DWORD buflen;
    TCHAR lpFilename[BUFSIZE]=TEXT("");

      buflen = GetModuleFileName(NULL, lpFilename, BUFSIZE);

      if (buflen == 0) {
          return (mxCreateString("") );
      }
      else {
          return (mxCreateString(lpFilename) );
      }
  }

Hi Kevin,

I'm not sure what the getmodulefilename is supposed to do,and even less, why you want to incorporate into your standalone executable?

Hi Titus: In 2002, I wrote an m file and compiled it into a standalone application. Suppose the m file is called XYZ.m and the application is XYZ.exe. Since different users may store XYZ.exe in different directories, I wanted XYZ.exe to be able to retrieve the path it is stored. This is because XYZ.exe has to take some user input through external files, which are supposed to be stored in the same directory. So, knowing the path, XYZ.exe can be directed to read those external files. A colleague gave me two c files: megetmodulefilename.c and mlgetmodulefilename.c. I created XYZ.exe by compiling it in MATLAB as follows

mcc -m XYZ.m mlgetmodulefilename.c

In XYZ.m, this line is used to retrieve the path

ProgramDir=fileparts(megetmodulefilename);

While mlgetmodulefilename.c is attached above, megetmodulefilename looks like

#ifndef MLF_V2
#define MLF_V2 1
#endif

#ifndef __megetmodulefilename_external_h
#define __megetmodulefilename_external_h 1

#include "matlab.h"

extern mxArray * Mmegetmodulefilename(int nargout_);

#endif

After 13 years, I find some bugs in XYZ.m, so I decide to modify it and re-compile it to XYZ.exe. That is where I see the warning and error message. Could you please give me a hand?
