MATLAB: P files cannot be analyzed to find their dependencies. Please add P file dependencies manually

arduinogui

Hello, I am making a standalone GUI application that uses the most recent Arduino support package. My GUI does not work because one certain file, as shown in the image is a .p file.

MATLAB advises me to 'P files cannot be analyzed to find their dependencies. Please add P file dependencies manually'.

To be exact, the file name is: 'C:\MATLAB\SupportPackages\R2015b\arduinoide\toolbox\realtime\targets\arduinoide \+ide\+internal\getArduinoIDERootDir.p'

I do not know how to work with .p files in such a manner and am unable to find any sources to solve the problem.

I'd start with a web search: Ask your favorite search engine for "Matlab get dependencies of P file". You will find e.g.:

There is a chance, that getArduinoIDERootDir.p does not call any other functions, which have not been included from somewhere else. So you could simply try it: Ignore the warning and check, if the resulting executable works reliably. If not, the error message might reveal the required subfunctions. Or use one of the above mentioned methods to analyze the dependencies.

[EDITED] You can call clear all at first and after calling the code, which contains the P-file, check the list of loaded functions:

[M,X,C] = inmem('-completenames');

Care for including these files.

MATLAB: Application Compiler crashes when selecting main file on Windows 10 R2017a

One of the things you can try is to compile the application directly from the MATLAB command window rather than using the deploytool. The command would look similar to the following:

mcc -o app1 -W WinMain:app1 -T link:exe -d C:\Users\userName\Downloads\mlapp\for_testing -v C:\Users\UserName\Downloads\app1.mlapp -r 'C:\Program Files\MATLAB\R2017a\toolbox\compiler\Resources\default_icon.ico'

As a reference for the exact command, you can also take a look at the packaging log that was generated for the Mac App.

More details on the mcc options can be found here .

MATLAB: How to use FileDependencies to make a standalone executable program available to the workers running MATLAB Distributed Computing Engine 2.0 (R14SP3+)

This issue occurs because the temporary directory for FileDependencies is added to the MATLAB path only, and not to the system path. This is the expected behavior. If you are using Release R2006b or later, use the getFileDependencyDir function in your task function to locate the executable on the workers' path, for example:

%Find the current directory for FileDependencies. 
ddir = getFileDependencyDir; 
%Change to that directory to invoke an executable. 
cdir = cd(ddir); 
%Invoke the executable. 
[OK, output] = system('myexecutable'); 
%Change back to the original directory. 
cd(ddir);

The getFileDependencyDir function does not ship with versions of MATLAB Distributed Computing Engine prior to Release R2006b. If you are using an older version, download the attached P-file, getFileDependencyDir.p, and make it available to your workers via the "FileDependencies" property of the job:

set(job, 'FileDependencies', {'myFile.exe', 'getFileDependencyDir.p'})

In your task code, use getFileDependencyDir in the same way as shown above, i.e., have the workers navigate to the directory containing the executable to run it from there.

An alternative to using "FileDependencies" is to put the executable on a shared file system accessible to all workers and update the system paths of all workers to include the path to the executable.
