Making Existing Native Code Available in Kotlin

on YouTube ↗17m

" summary

Shows how to call existing C/C++ libraries from Kotlin two ways: Kotlin/Native uses JetBrains CInterop with a small .def file to generate a .klib that links to the shared lib so you only need one wrapper; compilation uses gcc flags like -fPIC -shared .dylib. JVM requires writing a JNI C wrapper (example named greeter_jni) and building two shared libraries, then running a self‑executable jar with java -Djava.library.path; provided examples compile and run and full code is on GitHub.
