@orangy thanks. I mean on hardware without OS, some sort of 'kernel'. I can't find anything like that in his blog

gimlet: There was an attempt to get Kotlin Native ported to a uC (micro controller - https://github.com/JetBrains/kotlin-native/issues/458), however a brick wall was encountered (libffi doesn't support some Cortex M CPUs - https://github.com/JetBrains/kotlin-native/issues/458#issuecomment-293409748). 🙁

@napperley note, that libffi is needed only to call vararg C functions, so if you can live without it - simple stubbing out in couple places will let you continue

I take it that involves modifying the build process to remove the link to libffi for the uC targets (eg Cortex M4)? By supporting C code that means any embedded C libraries that are available for hw access (depending on the target hw)?

One could just supply empty ffi library with stub implementation of functions we need, literally one or two
