Hello, I am trying to port a linux native binary from .kt file. I could not find kotlin-native package in snap/apt in ubuntu. There is only kotlinc. Any idea how to quickly generate a native binary?

https://kotlinlang.org/docs/native-command-line-compiler.html but you should almost certainly just use Gradle instead

Sure let me try https://kotlinlang.org/docs/native-get-started.html#create-a-new-kotlin-native-project-in-intellij-idea. My attempt with https://github.com/JetBrains/kotlin/releases/tag/v1.8.22 throws errors.

You won't be able to use Java APIs in Kotlin native, it doesn't run on the JVM, there is no JRE. If you want to run JVM-based programs natively, consider GraalVM maybe

Got it. Thanks for mentioning. Otherwise it would have cost me lot of time to self realize. I will explore GraaIVM. btw I was trying to port simple utility to turnoff display when required https://raw.githubusercontent.com/arunmummidi/kotlin-tools/main/turnOffDisplay.kt

as much as I like Kotlin, there's no reason to use Kotlin for that, it's just wrapping a command line tool

yeah, it does dumb stuff. But it is to build some kotlin muscle for a noob. Not for prod use though ;)

By the way, I wouldn't use

assert

in that context.

assert

is meant only for debugging or confirming code correctness and only turned on if you explicitly enable it on the command line. In your situation, I would use

check

.

technically Kotlin's

assert

function is a bit different than Java's

assert

statement in that the condition is always evaluated by default (

-Xassertions=legacy

), instead of following the JVM's

-ea

, although the actual

throw AssertionError

are still controlled by

-ea

by default. given how tricky it is, I would also suggest to avoid

assert

which was already a mostly-bad idea in Java
