mcc insensitive to -a and -I options

Hi,

I'm building (or attempting) a standalone .exe of a function I use often. It is a process that I wish to run continuously on a server. The function has many depandancies in a large folder with several subfolders. This directory is rigid and not only I use it. Furthermore, the function has successfully been compiled before, but I don't know why these errors exist now.

My command for generating the executable

mcc -o output_fcn_name ...
    -W main:fcn_name ...
    -T link:exe ... 
    -v X:\folder\sub_folders\fcn_name.m

This code is based on unsuccessful attempts using the deploytool. When using the deploytool the executable does not show the disp('') commands I've put throughout the function to track my progress. However, this command results in the following error:

'[missing_function_name]' is not found in the current folder or on the MATLAB path, but exists in:

C:\folder\sub_folders

Change the MATLAB current folder or add its folder to the MATLAB path.

This is strange for several reasons:

1. The function IS on the Matlab path when compiling. I can call it and which -all missing_function_namme returns the location
2. Adding the function to the mcc command line by -a C:\folder\sub_folders\missing_function_namme.m does not correct the error
3. I can see the function in the C:\Users\usr_name\AppData\Local\Temp\usr_name\mcrCache9.3\ folder in the correct folder\subfolder
4. This error is thrown deep in the executable function. Several functions in the same overall C:\folder\sub_folders\ has been successfully called

I can solve the issue by putting the function in the current folder, but it then throws the same error for the next subfunction from that same folder tree.

I'm working on some X:\ drive calling dependancies from the C:\ drive if that is relevant. My working directory is X:\folder\sub_folder

Any suggestions?

Thank you!

-a C:\folder\sub_folders
-I C:\folder\sub_folders

Doesn't fix the error either

EDIT: spelling errors

I've tried several things:

mcc -o output_fcn_name ...
    -W main:fcn_name ...
    -T link:exe ... 
    -v X:\folder\sub_folders\fcn_name.m ...
    -a C:\folder\sub_folders

and

mcc -o output_fcn_name ...
    -W main:fcn_name ...
    -T link:exe ... 
    -v X:\folder\sub_folders\fcn_name.m ...
    -a C:\folder\sub_folders\missing_function_name.m

and

mcc -o output_fcn_name ...
    -W main:fcn_name ...
    -T link:exe ... 
    -v X:\folder\sub_folders\fcn_name.m ...
    -I C:\folder\sub_folders\

etc...

Hi Niclas Madsen,

I understand that you are trying to generate executable using MATLAB Compiler and facing ‘file not found on the MATLAB Path issue’.

One of the reasons for this error is not having read/write permission in the location where files are located. To resolve this error, follow the below troubleshooting steps,

1. Try to open MATLAB in administrator mode.
2. If you are using MATLAB Compiler from command prompt, then open Command prompt in Administrator mode.
3. Check if your user account has necessary read/write permissions.
4. If your use account doesn’t have necessary permissions, obtain the read/write permission.
5. Use ‘-m’ flag instead of ‘-W’ flag, refer the following example as a reference, https://www.mathworks.com/help/compiler/mcc.html#d126e22440:~:text=collapse%20all-,Create%20Standalone%20Application,-Create%20a%20standalone

For more information, refer the following MATLAB documentation,

1. https://www.mathworks.com/help/compiler/mcc.html#d126e21855
2. https://www.mathworks.com/help/compiler/standalone-applications.html

Hope this is helpful.

Your folder might have spaces in it, like "C:\Program files\"

Try enclosing the folders in double quotes:

mcc -o output_fcn_name ...
    -W main:fcn_name ...
    -T link:exe ... 
    -v "X:\folder\sub_folders\fcn_name.m" ...
    -I "C:\folder\sub_folders\"

If that doesn't work, try the function version of mcc instead of the command line version

mcc("-o",  "output_fcn_name", ...
    "-W", main:fcn_name, ...
    "-T", link:exe, ... 
    "-v", "X:\folder\sub_folders\fcn_name.m", ...
    "-I", "C:\folder\sub_folders\")

If it still doesn't work, call tech support.
