While compiling my program in MATLAB 2012a to create windows standalone application.I am getting errors.

While compiling my program in MATLAB 2012a to create windows standalone application.I am getting following errors:

Warning: an error occurred while parsing class emlcoder.InferenceReport: 
Undefined function 'findclass' for input arguments of type 'double'.

My code is

filename = 'testvid.avi';
hvfr = vision.VideoFileReader(filename,...
                      'ImageColorSpace', 'Intensity',...
                     'VideoOutputDataType','single');

%create a median filter system object    
hmedianfilt = vision.MedianFilter;  

%create contrast adjsuter system object
hcontadj = vision.ContrastAdjuster;

% create edge detection system object
hedge = vision.EdgeDetector( ...
                'Method', 'Prewitt', ...
                'ThresholdSource', 'Property', ...
                'Threshold', 10/256, ...
                'EdgeThinning', true);

%Create an AlphaBlender System object to overlay the edges on the original video frame.
hAB = vision.AlphaBlender('Operation', 'Highlight selected pixels');

%Create System objects to display the results.
playerEdge= vision.DeployableVideoPlayer('Name', 'Edge');

while ~isDone(hvfr)
  img = step(hvfr);      % Read input video frame

    % apply median filter
    image = step(hmedianfilt, img); 

    %contrast adjsutment
    image=step(hcontadj, image);

    %apply edge detection
    edges = step(hedge,image);

    %apply  AlphaBlender
    composite = step(hAB, image, edges);

    %play video    
    step(playerEdge,composite);
end  
% Close the video object
release(hvfr);

Seems similar to this previous question: http://www.mathworks.com/matlabcentral/answers/27493-building-standalone-application-fails-on-file-i-don-t-use

Try:

   >> mcc -m mytest.m -N -p 'C:\Program Files\MATLAB\R2011b\toolbox\vision'

but,what if I want to include more files.In my case,My project include 7-8 m files,5-6 .fig files,few .mat files and .jpg files.

Use the -a option to add additional files to the CTF archive. See: http://www.mathworks.com/help/toolbox/compiler/mcc.html

I am working in MATLAB 2012a on Windows7.I have created a project on image processing so I have created few m-files for different image processing functions.there is GUI where user can select different sources and then based on user selection,he is directed to different m files.Now i want to create a single executable with all m-files,fig files,mat files.

I am using MS VS 2010 compiler.When i use deployment tool and add all files to my project,it starts compiling but i get following error:

"Warning: an error occurred while parsing class emlcoder.InferenceReport: Undefined function 'findclass' for input arguments of type 'double'."

When I am running my matlab code,its working fine.then Why i am getting this error?

I experienced the same issue with R2012a, after having successfully compiled the same code on R2010b. Since it's just a warning I ran the compiled executable anyway, but it failed with an "ApplicationRedefinedException". Here's how I fixed the problem (not claiming that this solution works for everyone).

My code makes use of MEX-files generated with EMLMEX, so I figured it had something to do with that. I went through these steps (I'll list them all, even though some did not help to fix the issue). For the impatient, steps 5 and 6 fixed the issue.

1. Converted the scripts used to generate the MEX-files using CODER.UPGRADE

2. Using the converted scripts (that use CODEGEN instead of EMLMEX) re-compiled the MEX files. This did not solve the issue.

3. Changed my main routine to call the regular M-files instead of the MEX-files. This didn't fix the issue.

4. Searched the path for occurrences of "emlcoder". Deleted all files containing occurrences (such as backups generated by coder.upgrade), until there were no more occurrences. This didn't fix the issue.

5. One of the paths containing a MEX-file was included in the mcc command with the -a option. I changed this to the -I option (so that only files that can be determined to be needed at compile time are included). This fixed the issue.

6. However, I need this -a option for this path. I moved the scripts in this path used to generate the MEX-files (the upgraded scripts that don't make use of eml, but of coder) to another directory that is not included in mcc. This fixed the issue.

Hope this helps.
