Is it really not possible to use Kotlin/Native to compile to and execute windows-x86_64 on Windows 11 ARM 64?!

Is there anyway I can 'override' a property to allow this?

build.gradle.kts

plugins {
    kotlin("multiplatform") version "2.2.20" // "2.0.0"
}

repositories {
    mavenCentral()
}

kotlin {

    // windows
    mingwX64("native") {
        binaries {
            executable {
                entryPoint = "main"
            }
        }
    }

    sourceSets {
        val nativeMain by getting
    }
}

Error:

Execution failed for task ':commonizeNativeDistribution'.

Possible solution:
 - Declare repository providing the artifact, see the documentation at <https://docs.gradle.org/current/userguide/declaring_repositories.html>

the toolchain simply doesn't exist, you can't override it with a property

[ephemient]

I don't have access to Windows (on ARM or otherwise) but I believe it has the ability to run x86 programs through emulation. you can try running Gradle build with an x86 JVM, which should cause the Kotlin Gradle Plugin to detect x86 and use the toolchain for x86 Windows

Thank you @ephemient 🙏 Yes Windows on ARM can run x86 programs, I will try this out
