How to add cinterop to a common module like for example linux common module?
Copy code
val linuxSettings: org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget.() -> Unit = {
        val main by compilations.getting

        main.cinterops.create("x11") { defFile("src/linuxCommonMain/cinterop/cinterop.def") }
    }
    linuxX64(configure = linuxSettings)
    linuxArm64(configure = linuxSettings)
    linuxArm32Hfp(configure = linuxSettings)
Does not work 🤐 The package is inaccessible from
Copy code
val linuxCommonMain by sourceSets.creating { dependsOn(commonMain) }  <<----
val linuxX64Main by sourceSets.getting { dependsOn(linuxCommonMain) }
val linuxArm64Main by sourceSets.getting { dependsOn(linuxCommonMain) }
val linuxArm32HfpMain by sourceSets.getting { dependsOn(linuxCommonMain) }
I do have
Copy code
kotlin.mpp.enableGranularSourceSetsMetadata=true
kotlin.native.enableDependencyPropagation=false
in gradle.properites, and platform.posix works, so I guess cinterop should've been considered 🤔 But its not blob thinking upside down

1.5.20 milestone isn't reached right? Any current workaround, probably pointing same directory to both targets?

I guess old buildscript syntax gonna work, lets try that out
Adding this maven repo works https://maven.pkg.jetbrains.space/kotlin/p/kotlin/bootstrap
Copy code
// settings.gradle.kts
pluginManagement {
    repositories {
        gradlePluginPortal()
        maven("<https://maven.pkg.jetbrains.space/kotlin/p/kotlin/bootstrap>")
    }
}

So finally - does it work for you? My attempt failed - https://github.com/msink/kotlin-libui/commit/705f12a24973c22ce06cca3c5371995a1fcd32dc Result - https://github.com/msink/kotlin-libui/runs/2544545675 Here commonizer did run successfully:
Copy code

I haven't actually tried it out 😅 A js issue regarding interface export in 1.5.x was blocking me, so was busy finding a fix for that first.

Heh, searched in tests in kotlin repo - here are two new switches in 
gradle.properties:
kotlin.mpp.enableCInteropCommonization=true
kotlin.mpp.enableHierarchicalCommonization=true

After adding - build still fails, but differently:

Now it doesn't resolve

One evidence, its probably broken in some ways 👀
There's a ticket already saying affected version 1.5.20 actually https://youtrack.jetbrains.com/issue/KT-46257
