Hey there, I'm researching Kotlin Native and I'm wondering if it's possible to build a library instead of an executable. And if so, how do you then make that library callable from another language (for example C)

maku: currently, we do not support this mode of execution of Kotlin/Native as it requires significant design time for embedding API, however, one could rather easily emulate what you asked for by calling C function using interop like is being done in https://github.com/JetBrains/kotlin-native/tree/master/samples/concurrent/

Yeah, I saw that, but my use case is as follows: we have existing C code that's our main service. We also have a Kotlin package/module/library that provides some functionality, at the moment we transpile kotlin code to JS and run it from C process using JS VM. I'd like to get rid of the JS VM and just call the kotlin methods directly.

That shalln't be hard, just init Kotlin runtime, declare called functions with @ExportForCppRuntime annotations and call your API. See https://github.com/JetBrains/kotlin-native/blob/master/runtime/src/launcher/cpp/launcher.cpp
