When I want to create a multiplatform library In 1.4-rc I must specify at least one target. I would like to be able to create a library that only has common code. And any projects that includes this library should be able to use that code in any target. Using IR as a target it seems like this should be possible as any target should be able to use ir code. Anyone know if you can do this and how to do it?

What is IR?

Internal Representation, new compiled code format in 1.4. See https://blog.jetbrains.com/kotlin/2019/12/what-to-expect-in-kotlin-1-4-and-beyond/

You need to declare all targets you want to support (even if you don;t have any target-specific code)

Yeah, hopefully they will remove that requirement as it's a pain to have to build for all platforms for code that has nothing platform specific.

I think it's the final goal, to allow publish IR based libraries which do not depend on any platform, but it is not possible yet, as I know
