Hi everyone, I updated from Kotlin 1.3.72 to Kotlin 1.4.10 today and I'm getting the following compilation error when I try to build my multiplatform library.

Any idea what this is about? There are no references to my code on this error so I guess it's an issue inside Kotlin? Or is there anything I have to configure for this after the migration to to Kotlin 1.4 that can fix this?

@Franco Did you follow this guide for migration? https://kotlinlang.org/docs/reference/migrating-multiplatform-project-to-14.html

[Franco]

Hi @louiscad, I had not, I did now but I still get the same error

After doing some more googling I found this old issue that looks similar: https://github.com/Kotlin/kotlinx.serialization/issues/436

But that one appears to have been fixed a while back

The issue seems to be on the ios target, here is another part of the error that I didn't copy before:

e: Compilation failed: Unbound type parameters are forbidden: [Unbound private symbol org.jetbrains.kotlin.ir.symbols.impl.IrTypeParameterSymbolImpl@2447af93]

 * Compiler version info: Konan: 1.4.10 / Kotlin: 1.4.10
 * Output kind: LIBRARY

Should I report this as a new error on Youtrack?

[Franco]

I found an issue on Youtrack now that seems to be the same: https://youtrack.jetbrains.com/issue/KT-41006

@Franco My guess is that 1.4.20 will be released around Kotlin 1.4 Online Event, which is exactly one month from now. You can use a dev version in the meantime as stated in the issue comments though.

Thanks for the info @louiscad 🙂, at the moment I'm not using the ios target of this library so I just disabled it until 1.4.20 is released, once it's out I'll give it a try
