I am playing around with Multiplatform and Kotlin/...

# multiplatform

[diesieben07]

I am playing around with Multiplatform and Kotlin/Native.
I want to be able to use posix in code shared between Linux/OSX. However I cannot get this to work at all. I have set kotlin.mpp.enableGranularSourceSetsMetadata=true and kotlin.native.enableDependencyPropagation=false
like described in the docs. Then I have created a nativeMain source set:

val nativeMain by creating {
  dependsOn(commonMain)
 }

Then I have configured the linuxX64Main and osxX64Main source sets to depend on nativeMain. However I still cannot use posix in nativeMain.
This issue happens both when trying to compile with Gradle as well as in IntelliJ (types / functions cannot be resolved).

What am I missing?

1. You have to use macosX64Main - not osxX64Main
2. IDEA has the bug. But gradle build works fine.

1. Renaming the target (and thereby sourceset) to macosX64 does not help.
2. gradle build does not work fine (like I said above). It shows "unresolved reference: platform" for import platform.posix.*

I've pushed my Code to github: https://github.com/diesieben07/konan_test

I believe he meant to change the target, not just the name. i.e. instead of

kotlin {
  osxX64("macosX64") {...}
}

Do

kotlin {
  macosX64 {...}
}

[diesieben07]

That is what I have:
https://github.com/diesieben07/konan_test/blob/master/build.gradle.kts#L24

[diesieben07]

osxX64 would not even compile

[Big Chungus]

My bad, thought they've added a shortcut for that same as for ios

I have a working example of such a shared POSIX. I don't have HMPP enabled. https://github.com/arkivanov/MVIKotlin/blob/master/mvikotlin-timetravel-proto-internal/src/nativeCommonMain/kotlin/com/arkivanov/mvikotlin/timetravel/proto/internal/io/ReaderThread.kt

Imports are red in IDE, but it does compile.

[diesieben07]

Okay, so I have to explicitly not enable the thing that the documentation tells me I need to enable for it to work.
Very strange. But it does compile for me using Gradle now, thanks Arkadii

If you want it working in IDEA - something like this should work:

kotlin {
    linuxX64()
    macosX64()
 
   targets.withType<KotlinNativeTarget> {
        sourceSets["${targetName}Main"].apply {
            kotlin.srcDir("src/nativeMain/kotlin")
        }
    }
}
