Kotlin-native: Cannot compile to linux target on macOS

[jiasir]

My kotlin-native compiler was up-to-date and cannot compile to linux target on macOS:

$ kotlinc main.kt -target linux -o main
exception: java.lang.IllegalStateException: Target LINUX is not available on the MACBOOK host

    at org.jetbrains.kotlin.cli.utilities.MainKt.main(main.kt:115)

And here is my build.gradle file:

buildscript {
    ext.kotlin_version = '1.2.10'

    repositories {
        mavenCentral()
        maven {
            url  "https://dl.bintray.com/jetbrains/kotlin-native-dependencies"
        }
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-native-gradle-plugin:+"
    }
}

apply plugin: 'konan'
apply plugin: 'idea'

konan.targets = ['macbook', 'linux']

konanArtifacts {
    program('scavenger')
}

The gradle build output has the following warrning:

The target is not enabled on the current host: linux

Isn't it clear that you can't compile to Linux on a macOS host? 🤔

@StefMa I wanna build my project to a linux binary on my macOS system and how to? ths!

[olonho]

Not all cross-compilation host/target pairs are supported, see https://github.com/JetBrains/kotlin-native/blob/master/RELEASE_NOTES.md for details.

If you haven't access to a Linux machine you can create a Docker image,
mount your project and let the image build your app...

Golang can be cross-platform compiler, such as I can compile Linux binary or Android binary on my macOS. Does Kotlin support cross-platform compilation in the future? I think Kotlin's Native future must be very strong! Kotlin is very advantageous!
