I am trying to build the hello world program for ...

# kotlin-native

[pajatopmr]

I am trying to build the hello world program for kotlin native on a macos system. I think the fact I am failing miserably is due to stale documentation. Basically, I tried both downloading from GitHub and using brew. Neither one has konan (is this still a thing?) or kotlinc-native whereas kotlinc -version advertises itself as kotlinc-jvm … Can someone supply a link for a newbie to Kotlin native to build a macos executable for hello world or some simple basic program.

I did manage to find https://github.com/msink/hello-kotlin which gets me off the dime but hides what is really going on for Gradle doing the heavy lifting. Is the kotlin-multiplatform plugin sufficiently readable so that I can figure out what is going on under the hood?

[gildor]

To do what is going under the hood you can check Gradle MPP plugin sources

[gildor]

But what exactly you want to know?

[gildor]

Also, are you sure that you need multiplatform?
Because if you just build an app for macos pure Kotlin-Native is enough, no need to configure MPP project

[pajatopmr]

I thought I was using pure Kotlin-Native by downloading the compiler from Github but there is no kotlinc-native compiler as some documentation suggests I should use.

[gildor]

There is Kotlin Native compiler

https://github.com/JetBrains/kotlin/releases/tag/v1.3.0

Direct link
https://github.com/JetBrains/kotlin/releases/download/v1.3.0/kotlin-native-macos-1.3.0.tar.gz

[gildor]

unzip this TAR file, and just run bin/kotlinc hello-world.kt

[gildor]

you will get something like program.kexe which is executable mac native binary (without optimisation, dependencies, config etc)

[olonho]

but recommended approach is to use IDEA (including free community edition) with Kotlin plugin

[Jurriaan Mous]

The easiest way to start with Kotlin Native for macOS is to start a new native project in Intellij Idea. It creates a Hello World kexe

[christophsturm]

how can i run the project that idea creates? neither the main class nor the test class offers to run it

[gildor]

You can use runProgram Gradle task

[christophsturm]

ok no way to run tests from inside idea?

[gildor]

Gradle task yourPlatformTest

[gildor]

For now Idea doesn’t have built-in integration with K/N test runner

I am getting this same issue. I try to run kotlinc-native -version in the terminal on macOS and the kotlinc-native command is not recognized. I installed kotlin on my system and kotlinc is recognized (though it prints *info:* kotlinc-jvm 1.3.70 (JRE 13.0.1+9))

I just can't get kotlinc-native command to work for some reason.

[gildor]

You installed Kotlin JVM
How do you exactly install it?

[j.l.]

I think it was the default when I installed kotlin. I also have kotlinc-js and kotlinc compilers just as a default. I do not think kotlinc-native comes with kotlin out of the box. You have to install kotlin native separately, if i am not mistaken.

[gildor]

Kotlin-jvm + Kotlin-js are bundled together, native is a separate compiler and distribution.

[gildor]

My question was how exactly you installed Kotlin, there are many ways to do that

[gildor]

If you need command line version, just download it from kotlin-native repo

[j.l.]

It took me a while to figure out. The kotlin compiler documentation confused me.
