how to generate MEX from package function in MATLAB?

I have the following directory structure:

    main
       +model
          run.m
       +options
          opt.m
    main.m

and so forth.

I have a function under `+model` directory called `run` that depends on some functions in the `+options` directory, such that my `main.m` script under directory `main` calls `model.run()` and the function `run` calls some `options.opt()`.

I want to generate a MEX file of `model.run()`, so I run the `coder` from MATLAB command prompt, and on the first screen, where I enter the function name to generate code for, I type

    model.run

and the coder simply displays the error:

    This file is shadowed by C:\....\main\+model\run.m

I already tried adding the `main` directory to the path, but it didn't work.

• Is it even possible to compile a MEX for any package function, such as `model.run()` in this scenario?

MATLAB version: '9.4.0.813654 (R2018a)'

Perhaps if you create a new function that just calls model.run() and ask to generate code for the new function ?

Functions within packages are not supported as entry-point functions. (Current as of R2018b)
