Beginner question... Can anyone point me to an example of linking/calling a rust dynamic library from a kotlin native application? I'm expecting some kind of c interop, but the lack of header files in the rust works leaves me a bit puzzled.
This is purely for experimental purposes, not for any real world problem.

make header files for Rust as you would for C

ok...spent much longer than I care to admit trying to solve this. After much experimentation, I create a "C" based header file, and managed to come up with a def file that sort of works...except at build time:

The /home/nheitz/.konan/dependencies/x86_64-unknown-linux-gnu-gcc-8.3.0-glibc-2.19-kernel-4.9-2/x86_64-unknown-linux-gnu/bin/ld.gold command returned non-zero exit code: 1.
output:

My trivial .so object references glibc "stuff" that the kotlin linker just doesn't see. Any suggestions?
