Seems like klib formats clash. Does cleaning & rebuilding help?

[soywiz]

I tried ./gradlew clean + ./gradlew --stop several times before posting including several combinations of Kotlin versions. It is a bit strange because with master I don't have this error (but get some other link-time errors).

Going to try again just in case I missed something and get in touch again with the results.

Reproduced here: https://travis-ci.org/korlibs/korlibs/jobs/415351482#L2584-L2639

I thought that everything was compiled from source, but now I remember that I was using kotlinx.coroutines 0.24.0. So my bet is that somehow it is not compatible.

If you can confirm it is due to that. I would propose the following:

• Request a new version of kotlinx.coroutines compatible with 0.8.2
• Keep a table with compatible versions of kotlinx.coroutines with kotlin-native
• Insert a binary version tag in the libraries, and change it each time the binary serialization format changes
• Check that version when loading a library and fail fast and providing information about the offending library

[homuroll]

Thank you. Actually there is a version tag in a library, seems like there is a bug in the algorithm that builds it.

[homuroll]

Fixed.
