Standalone application works in MATLAB but not outside

I have an application that works perfectly in MATLAB but when compiled as a standalone application does not...

With a try and catch statement I think I discovered that the problem is the data file... I have a data file called Data.mat, I think that the standalone application is not able to find it. The function I am using to find the path for Data.mat is the following:

function thePath = showpath()
% Show EXE path:
if isdeployed % Stand-alone mode.
    [status, result] = system('set PATH');
    thePath = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
else % Running from MATLAB.
    thePath=pwd;
end

The main program call this function in this way:

try
    imgFile1 = fullfile(showpath, 'Data');
    shipp=load(imgFile1);

catch err 
    if ~exist(imgFile1, 'file');
    errordlg('File does not exist','Input Error');
    else
    rep = getReport(err, 'extended');
    msgbox(rep)    
    end

end

Where is the mistake?

Answer FOUND:

The SYMS function is part of Symbolic Math Toolbox. You cannot compile any
functions from Symbolic Math Toolbox.

Is there any way to have my application compiled?

Answer 2

[Robert Cumming]

if your code isn't working that indicates your variable

thePath

is different when deployed and when not. Try printing it to the screen to check what it is. e.g something like:

function test
  disp ( ['PWD=', pwd ] );
  disp ( ['showPath=', showpath] )
end
function [thePath]=showpath()
  % Show EXE path:
  [status, result] = system('set PATH');
  thePath = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
end

Check function both in Matlab and compiled.

I make a step backward, just to be sure....

When I compile (deploytool --> select my main file --> I click Build) the file "Data.mat" disapears, so once it is compiled I don't see it inside any folders (src and distrib ... what is the difference between these two folders?).

Is it still correct to load a file that I don't see? If there isn't any file...how can the software find it? If this is not correct how can I resolve it?

Have you added Data.mat to the "Other files" section in deploytool?

[condor]

Yes, look below please

Answer 4

[Robert Cumming]

I've never used the deploytool - I still do everything from command line.

But having a look at it, have you added your Data.mat to the package, then after you build the exe you package it up - which will create a ZIP file or a self extracting exe which should contain your exe and data file...

Answer 5

[condor]

I added the Data.mat on the deploytool GUI file but I don't see it...?! (Another thing, in the code I use symbolic object, is the toolbox symbolic math added automatically?)

These are the details that the copiler returns me:

Answer 6

[condor]

When the software is compiled I only see 2 folders:

1) src:

• mccExcludedFiles
• readme
• exe file

2) distrib

• readme
• exe file

I still not understand the difference between the two folders...

[Robert Cumming]

src is the files generated by the compiler during compilation

distrib - is the files to be distributed.

[condor]

which should I use when I test? Where should be the Data.mat?

Answer 7

[condor]

Changing the try and catch as the following:

try

        imgFile1 = fullfile(showpath, 'Data.mat');

       shipp=load(imgFile1);

catch err 
    %if ~exist(imgFile1, 'file');
    %errordlg('File does not exist','Input Error');
    %else
    rep = getReport(err, 'extended');
    msgbox(rep)    
    %end

end

I got the following (the name project is 'Untitled1'):

Error using load
Unable to read file C:\User\quant\Desktop\Untitled1\src\Data.mat: No such file or directory.

But as you can see above I added Data.mat...where am I mistaken?

[Robert Cumming]

did you add it to the build or the package part?

can you see the file in the dir? (I suspect not)

[condor]

look below please...

[Robert Cumming]

if you look in explorer do you see the file?

Answer 8

[condor]

@ Robert: I add it to the build and I don't see it... What do you mean if I see the file in the dir?

If I use:

mcc -mv ProgramWindow.m -a Data.mat

I get the following error:

??? Undefined function or method 'sym' for input arguments of type 'char'.
Error in ==> ProgramWindow>pushbutton1_Callback at 2223

Maybe this because I am not adding the symbolic toolbox?
