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

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

Do

kotlin {
  macosX64 {...}
}

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

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

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")
        }
    }
}
