Matlab Coder Windows -> Linux cross-compilation

Version: Matlab 2019b

Task: from Windows compile Linux static library (.a) to be used in Android application.

Current state: on Windows Matlab Coder allows generation of .lib, .dll only.

I saw there are threads for cross-compilation, does anyone made it work and can provide detailed instruction?

Check out:

That links to a webinar which shows generating code for iOS and Android. Here, you're probably not going to cross-compile from Windows to Linux but generate code only and then use the Android NDK to compile that code outside of MATLAB Coder.

One of the main considerations is to set up the HardwareImplementation config property to match your Android device. With that, the generated code will be compilable by the Android NDK.

Wow, thanks for quick and precise reply!

Btw, do you plan to add cross-compilation to Matlab Coder?

If so, when it may be released (approximately, of course) ?

MATLAB Coder and Simulink Coder already support various forms of cross-compilation. To use that you'd select a different toolchain in the App or in the config object. Installing support packages can give you access to various other toolchains, like Raspberry Pi:

That page also has a Request new hardware support button in the bottom right that you can use.

You can also create and register your own custom toolchain:
