HI,

I am really very Frustrated of doing mex stuff, I am trying for more than 3 Days I know there is very little thing that need to be done to make mex displayImage.cpp to work

I have installed VS10, SDK7.1, MAtlab2012a,opencv 2.3, Everything is fine

Also I am not able to run mex-setup again it giving me following error

    mex-setup
    Usage: 
        MEX [option1 ... optionN] sourcefile1 [... sourcefileN] 
            [objectfile1 ... objectfileN] [libraryfile1 ... libraryfileN] 
    Use the -help option for more information, or consult the MATLAB API Guide. 
C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: No file names given. 
Undefined function or variable 'setup'

and if I run the cpp File it gives me following error

 mex displayImage.cpp
displayImage.cpp 
displayImage.cpp(5) : fatal error C1083: Cannot open include file: 'stdio.h': No such file or directory 
C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: Compile of 'displayImage.cpp' failed. 
   Error using mex (line 206)
  Unable to complete successfully.

even stdio.h is inside the folder of my current working Directory.

Looking forward....

Thanks and regards

thanks for this correction but now I am still getting this error Please can you tell me how to set all the procedure to accomplish mex compilation, the error

   mex -setup
Welcome to mex -setup.  This utility will help you set up  
a default compiler.  For a list of supported compilers, see  
 http://www.mathworks.com/support/compilers/R2012a/win32.html 
   Please choose your compiler for building MEX-files: 
   Would you like mex to locate installed compilers [y]/n? y
   Select a compiler: 
   [1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2012a\sys\lcc 
  [2] Microsoft Software Development Kit (SDK) 7.1 in C:\Program      Files\Microsoft Visual Studio 10.0 
   [3] Microsoft Visual C++ 2010 in C:\Program Files\Microsoft Visual    Studio 10.0 
 [0] None 
Compiler: 3
   Please verify your choices: 
Compiler: Microsoft Visual C++ 2010   
Location: C:\Program Files\Microsoft Visual Studio 10.0 
Are these correct [y]/n? y

@Kaustubha Govind, Also I am giving path in mexopts.bat is given below

 set OPENCVDIR=C:\opencv;
 set LIB=%OPENCVDIR%\build\x86\vc10\lib; 
 set PATH=%OPENCVDIR%\build\x86\vc10\bin;
 set INCLUDE=%OPENCVDIR%\include\opencv\cvaux;
 set INCLUDE=%OPENCVDIR%\include\opencv\cv;
 set INCLUDE=%OPENCVDIR%\include\opencv\cxcore;
 set INCLUDE=%OPENCVDIR%\include\opencv\highgui;
 set INCLUDE=%OPENCVDIR%\include\opencv\cvcam;
 and set LINKFLAGS=/dll /export:%ENTRYPOINT% /LIBPATH:"%LIBLOC%" libmx.lib libmex.lib libmat.lib cv.lib cvaux.lib cxcore.lib cxcore.lib highgui.lib cvcam.lib /MACHINE:X86 kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib /nologo /manifest /incremental:NO /implib:"%LIB_NAME%.x" /MAP:"%OUTDIR%%MEX_NAME%%MEX_EXT%.map"

all this is in the guideline given in the mathworks website, I tried to do as it is and Environment variable I set is OPENCVDIR C:\opencv\build

and Path Variable is edited as %OPENCVDIR%\build\x86\vc10\bin

I dont where I am wrong ????

@Jan, also This is the code of displayImage.cpp

/******************************************************************* This is a simple MEX file. It just calls OpenCV functions for loading, smothing and diaplaying the results ******************************************************************/

 #include <stdio.h>
#include <stdlib.h>
#include <cv.h>
#include <highgui.h>
#include "mex.h"
 int smoothImage(char* filename){
    //load the image
    IplImage* img = cvLoadImage(filename);
    if(!img){
            printf("Cannot load image file: %s\n",filename);
            return -1;}
    //create another image
    IplImage* img_smooth = cvCloneImage(img);
    //smooth the image img and save the result to img_smooth
    cvSmooth(img, img_smooth, CV_GAUSSIAN, 5, 5);
    // create windows to show images
    cvNamedWindow("Original Image", CV_WINDOW_AUTOSIZE);
    cvMoveWindow("Original Image", 100, 100);
    cvNamedWindow("Smoothed Image", CV_WINDOW_AUTOSIZE);
    cvMoveWindow("Smoothed Image", 400, 400);
    // show the images
    cvShowImage("Original Image", img );
    cvShowImage("Smoothed Image", img_smooth );
    // wait for a key
    cvWaitKey(0);
    //destroy windows
    cvDestroyWindow("Original Image");
    cvDestroyWindow("Smoothed Image");
    //release images
    cvReleaseImage(& img);
    cvReleaseImage(& img_smooth);
    return 0;};
 void mexFunction(int nlhs, mxArray* plhs[], int nrhs, const mxArray* prhs[]){
    if (nrhs != 0){
        mexErrMsgTxt("Do not give input arguments.");}
    if (nlhs != 0){
        mexErrMsgTxt("Do not give output arguments.");}
    char *name = "cameraman.png";
    smoothImage(name);}

one thing I have seen that when I run mex -setup then it wipe out all paths that are newly added to it, and therefore it can not find cv.h or else things

Please test, if cv.h is where you expect it:

exist('C:\opencv\ch.h', 'file')

Try the quotes instead of < and >:

#include "cv.h"

i have the exact same problem. i have also read on a page that matlab 2012a and visual studio 2010 donot support initially there is a patch for this purpose i have downloaded this patch and placed in the matlabroot but the problem remains the same the error i am constantly getting is : mex displayimg.cpp Error: Could not find the compiler "cl" on the DOS path. Use mex -setup to configure your environment properly.

C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: Unable to locate compiler. 
plz give me some helpful suggestions thanx.

This error is unrelated to what Muhammad is reporting -- I recommend you begin a new topic.

I would not reinstall MATLAB or Visual Studio; you have a path problem that reinstalling will not solve.

Are you sure cv.h is in C:\opencv, and not a subfolder under it? I am not familiar with OpenCV, but I would try:

mex -IC:\opencv\include\opencv displayImage.cpp

If that fails, open the Explorer and locate the name of the folder where cv.h is found. Wherever that is, put that folder name (not filename) as the -I parameter to MEX.

And, yes, if you rerun "mex -setup", it will clobber any customization you may have made to mexopt.bat. In general, I would only edit this file as a last resort.

@Ken Atwell, your answer is very Logical it should solve the problem, I can show what I got , I Have tried from two different Path to access ch.h, it is accessing it but Still some problem, i am so sorry lot of troubleshooting could not solve it,

 mex -IC:\opencv\opencv\include\opencv displayImage.cpp
displayImage.cpp 
C:\opencv\opencv\include\opencv\cv.h(63) : fatal error C1083: Cannot open include file: 'opencv2/core/core_c.h': No such file or directory 
C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: Compile of 'displayImage.cpp' failed.
