Hello guys, I am trying to use a C-library in my Kotlin based app. I have gone through the official documentation, but I didn't find a resource that explains how to add a C-library as dependency to an Android Project and can be used in the SharedCode Kotlin module! Any help appreciated.

Hello.
As we have discussed earlier
https://kotlinlang.slack.com/archives/C3PQML5NU/p1559830111022800
you can’t add C library to Android project using Kotlin/JVM.

[Kruger Brent]

is there any way to add a C-library at all without using Kotlin/JVM and still use it in an Android app?

[svyatoslav.scherbina]

No, Kotlin/JVM is Kotlin backend used for Android apps.

[Kruger Brent]

oh, okay. Thank you. Suppose I have a library like this https://libzip.org

[Kruger Brent]

How do I use it?

[Kruger Brent]

And what about C++ library?

The only option currently available for native library on Android is to wrap it manually with JNI.
Some extra wrapping would be required to use this library in common code (which is compiled to both Android and iOS).

Thank you @svyatoslav.scherbina

@Kruger Brent check out Djinni

[Kruger Brent]

Cool. Yeah just stumbled over that. Thanks though @Kris Wong

[Kruger Brent]

@Kris Wong does it translate the C code to C++?

[Kris Wong]

no

[Kris Wong]

it generates the bindings

How do I link a CPP module in a kotlin/native project? I mean there aren't any samples explaining that anywhere on the kotlin website. A sample gradle file to include a CPP module or something like that!

Importing C++ libraries is not supported.
