Are there kotlin bindings for libffi?

[loke]

Nothing ready-made I think. But I just included it using cinterop and it was very easy.

I then created a higher level FFI that calls into either Kotlin native using libffi or using the new java.lang.foreign for JVM.

That is pretty much what I wanted to do, do You have some sample code available for the setup that You can share?

[loke]

The project is open source. This would be the main entry point: https://codeberg.org/loke/array/src/branch/master/contrib/ffi-mod/src/commonMain/kotlin/com/dhsdevelopments/kap/ffi/ffi.kt

There is a linux and a JVM backend (the latter requiring Java 21)

It's a work in progress, so it may be a bit messy, but at least it should be able to give you some inspiration.

Thank You very much!

[loke]

No problem. I hope it helps.

I just found a mistake in my project. The cinterop file for libffi is in the wrong module (I forgot to copy it when I moved ffi-mod to its own module). You can find it here: https://codeberg.org/loke/array/src/branch/master/array/src/nativeInterop/cinterop/libffi.def

It builds because ffi-mod depends on array , but it's a bit ugly. I'll fix it.
