10/31/2023, 4:58 AMHow would I add arm64 support to my native linux x64 project? Currently I have this in my gradle config
Copy code
linuxX64("linux") {
binaries {
executable("prism") {
entryPoint = "main"
}
}
}j
Jeff Lockhart
10/31/2023, 6:29 AMChange to:
Copy code
linuxX64 {
binaries {
executable("prism") {
entryPoint = "main"
}
}
}
linuxArm64 {
binaries {
executable("prism") {
entryPoint = "main"
}
}
} Copy code
targetHierarchy.default()z

10/31/2023, 8:18 PMCan I do the binaries configuration on both? so I don't need duplicate code

it.binaries {

Copy code
kotlin {
listOf(
linuxX64(),
linuxArm64()
).forEach {
it.binaries {
executable("prism") {
entryPoint = "main"
}
}
}
sourceSets {
linuxMain {
dependencies {
implementation(projects.common)
implementation(libs.clikt)
implementation(libs.kotlin.coroutines.core)
implementation(libs.bundles.ktoml)
implementation(libs.bundles.ktor)
}
}
}
}Cannot access 'com.akuleshov7.ktoml.source.TomlSourceReader' which is a supertype of 'com.akuleshov7.ktoml.file.TomlFileReader'. Check your module classpath for missing or conflicting dependencieslet me try this option i see in the gradle logs
kotlin.mpp.enableCInteropCommonization=truenvm that causes many many more errors
Common is just this
Copy code
plugins {
alias(libs.plugins.kotlin.multiplatform)
}
kotlin {
listOf(
linuxX64(),
linuxArm64()
).forEach {
it.compilations.getByName("main") {
cinterops.create("xlib")
}
}
}j

11/01/2023, 10:49 PMThis error indicates you're using a dependency which doesn't include the linuxArm64 target, specifically https://github.com/ajalt/clikt in this case. You'll need to be sure all your dependencies support the target before you're able to add support yourself.

11/01/2023, 10:58 PMFor most dependencies that already support linuxX64, it should be straightforward to add linuxArm64 as well. You might be able to contribute the target in a PR. Many libraries have been adding support, since it's now officially a tier 2 target. The real issue has been being able to run CI tests on the platform. I was able to add *linuxArm64* support to my own library recently, once support became available in all dependencies.
