App Designer: App runs from Matlab but not after Compiler

25 次查看(过去 30 天)
Hi everyone,
I have an app created in App Designer. If I run it directly from Matlab/App Designer everything works perfect. But after I used Matlab Compiler the app doesn't work anymore. In my startup function I call this function
app.Config = ConfigFunction(app);
to load the startup values set on the GUI to app.Config (which is a private property). This seems to create an error after Compiler is used. I have set a couple of message-boxes to figure out where the error occurs.
But why is everything working fine befor compilation and after compilation the .exe doesn't work?

I don't know, I never use Application Compiler app or compiler.package.installer. I use MCC command directly.
You need to make distinction how you open the text file, full path, relative path, etc... and use
isdeployed
function to determine which case the app is runing. I use this function to return the root path of the app, then read the file relative to the app root directory.
function currentDir = getcurrentdir
% currentDir = getcurrentdir
if isdeployed % Stand-alone mode.
[~, result] = system('set PATH');
currentDir = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
else % MATLAB mode.
thisfile = mfilename('fullpath');
currentDir = fileparts(fileparts(thisfile));
end
Of course you have to put the text file at the corresponding places.
