Support for non-GNU Linux distributions (Alpine, Adelie)
Jetbrains, despite their bountiful wisdom, have not made Kotlin/Native libc-agnostic. This means that Wraith Master cannot compile or run on distributions that don't use glibc as their libc implementation (such as Alpine).
YouTrack Issues
JetBrains replied to my query on how soon we can expect this to be implemented, and said that while binary support doesn't fit into the Kotlin 1.4 release window, we can expect an update on the target version soon.
To be perfectly clear: As soon as Kotlin/Native supports Alpine and Adelie, Wraith Master will support Alpine and Adelie.
Update (2020-11-06)
JetBrains have made their plans for binary support clear in the linked issue. As it stands, they plan to add a new compiler target that can link dynamically against musl. In the meantime, options will be added to the Kotlin/Native compiler to allow projects to link statically against glibc. This isn't ideal, but it is a possible temporary solution until dynamic linking against musl is added.
As of the currently unreleased v1.2.0, Wraith Master will ship with an executable that has been patched to link against gcompat directly. This also isn't ideal, but it fixes Wraith Master's inability to launch at all on Alpine and Adelie. Once the aforementioned static linking with glibc has been added, this "gcompat" distribution of WM will be replaced with a statically-linked version, and then eventually a musl-linked version.
