Hello, I'm new to native, is it possible to use a c++ library from kotlin ? Use case : Multiplatform kotlin library that targets native would be able to use existing c++ library in its native code definition (since most Kotlin Multiplatform library are JVM or JS only)

Only via C. Direct cpp interop is postponed

In general is it the recommended approach (to use C interop and try to call c libs)? Or is it better to look for ways the users of your kotlin multiplatform lib could call the JS target instead of native ? Native seems to be still relatively new in the ecosystem, not a lot of KMP seem to offer it

Not sure how cpp relates to js, sorry 😀

What I'm saying is maybe if your library users are c++ apps, then maybe it's better to ditch native and target JS (Assuming c++ can call JS). Would have to double check but pretty sure c++ can call JS

But kotlin really cares only about the headers. Some cpp issues provide c headers so see if your lib has that

Ok thanks

Even if cpp can call js, that would be a significant performance hit and as such I'd personally try to avoid it.

Yes for sure, but at least that'd be a solution to start off with.

I think writing your own C layer to interop between the two would be a better way to go

Interesting idea, I would need to define C headers for the kotlin lib and call my c++ lib from

.c

files?

Something like that. I've never actually done it myself, just an idea.
