Hello,
I'm trying to compile a Stand Alone Utility.
Source code is based on folders tree with many layers and functions (it's a ~ 10 years legacy code).
I receive error in "deploytool" for trying to compile functions with Matlab error inside. I've tried to fix the errors manually, one by one, but there are just too many.
Is there an automated process, in which I could simple check something like "ignore files with code error"?
I know for 100% my GUI won't be using those files with error code, that's why I don't afraind to remove them entirely from my compilation.
I'm familiar with the function "checkcode". But in order to use it, I have to run over ALL the "milion" files in my GUI, and I'm trying to avoid that.

Please post the code, and which C compiler you have configured with MEX to compile the code, and a list of the output errors. Otherwise we cannot reproduce your problem and do not know what errors you are having.

Thank you.
  1. I'm not compling for C, MEX, etc... I'm compiling MATLAB GUIDE to a Stand Alone executable.
  2. Imagine your GUI is build on 1000 functions, spread over 100 folders... (like I said, it's an very old and cumbersome legacy code). Some of these function have "silly" errors like
a =
I can go one-by-one, and simply comment out these probalamatic lines.
BUT, it's a very tedious and time consuming process.
I'm asking, if MATLAB can somehow ignore all the files with errors inside, and simply create my utility + log file near by, saying something like: "here's is your exe file... but, pay attention, the following file couldn't been compiled..."
I hope it's clearer this time :)

With lots of silly errors, are you even able to run it in the MATLAB IDE? If so, can you simply use
>> mcc -m yourMainFile.m
to compile your app? If not, what does it say? It shouldn't matter if there are hundreds of functions being called as long as they are all on the path -- it will find them. Sometimes the code will only throw an error during run-time so of course the compiler won't know or care about those lines of code. However if there is a syntax error in your main program, it won't compile. Not sure if syntax errors in dependent m-files will be caught during the compile process or not.
I compile standalone apps built with GUIDE every day.
