Compiler ignores MCC options

Dear,

Since I updated to r2025a, I'm encountering issues with the compiler.build.standaloneWindowsApplication method.

In the buildOpts struct I parse to this function, I specify `AdditionalFiles`, but they are not included in the build (nor in the compiled package).

I did some debugging on the builder, and both builder.MccInfo.MccInput as builder.MccInfo.MccCommandString show the Additional files correctly, but once premcc, mcc and postmcc are called, the files are never added to the `FilesToBeDeployed` array (except the icon, splashscreen, and executable).

It seems to be that MCC is ignoring the input commands it receives. With r2024b, this issue did not exist, and the AdditionalFiles were added succesfully at each compile.

How can I fix this?

Best Regards,

Jelle

I just contacted them. I'll keep this question up to date with their response.

On the deployed/target system, where did you look for the additional files that were to be included/shipped?

[Jelle]

The location where r2024b also putted its "AdditionalFiles", being [installation_directory]/application. This is also the directory in which the executable, splashscreen file and icon file are written to. When manually copying the files I added to "AdditionalFiles" in this directory, the application finds all files as expected.

Did you use the cd function anywhere in your code? Did you (hopefully) always use fullfile to construct full file names of the files you want to access? See the FAQs:

Yes, I'm well aware of those coding practices and apply them. In r2024b this also never gave an issue. Only since updating to r2025a the compiler itself just refuses to package the "Additional Files" I select with the executable.

When adding the files manually to the directory r2024b generated executables put (/ installs) them, all works fine.
