Matlab codegen generate version-script for gcc

Hello,
Is there any way to generate a .map file that can be passed as version-script to gcc similar to what is described here ? I'm generating the code on windows (for a linux platform) because of some compatibility issues and I move the generated code to a Ubuntu machine so that I can generate a shared library .so file using gcc and the shared library will be used in a product that runs on Ubuntu.
I would like that this library exports only the minimum functions so that the user of the library will not get confused by all the internal functions. That's why this .map file should contains only the bare minimum functions required to execute the matlab generated code (the function names passed to codegen). Since I'm generating code on Windows, it seems that this .map file is not generated even if I've setup my configuration for Linux. Here is my embedded coder configuration:

This is what the command line says when I gerate code:
### Using toolchain: Microsoft Visual C++ 2017 v15.0 | nmake (64-bit Windows)
### Creating 'C:\Users\Admin\AppData\Local\Temp\tp1a8d2527_b6a1_4501_b6be_4dc2359394fd\dll\nirJob_rtw.mk' ...
Code generation successful: View report
It seems that it uses Visual Studio toolchain but I don't want to to build I only need to generate the code and the .map file.
Do I need to set other flags so that the .map file is also generated ? Do I have to generate the code on Linux host?
Thank you.
