Has anyone tried tying Godot’s C API Interface to Kotlin Native yet? https://godotengine.org/article/dlscript-here

I wonder if kotlin-native also aims to run on ARM based MCUs like STM32 eventually

Is it possible to call klib functions from an shared library?

Is there any support for Kotlin-Native in CLion or something similar? I am looking to create simple project in kotlin-native with vulkan (as vulkan is written in C I hope there wasn't so many problems).

Can kotlin native emit shared objects

is using a C main function a supported use case for the

-nomain

flag? I've been trying to get something like

konanc -nomain foo.kt -linkerOpts main.o -e main

to work (where main.c is a C hello world) but i'm getting stuck on

function Konan_start: error: undefined reference to 'EntryPointSelector'

, wondering if theres an obvious flag im missing

alternatively, is there any way to get a .so from the K/N bitcode? i've tried rolling my own with

llc -relocation-model=pic

on the emitted bc but eventually get stuck at the deps being compiled without fPIC

@benleggiero Not yet, but there is a work in progress for one of the upcoming releases.

Roughly how big in size (KB) is the Kotlin Native runtime and standard lib? Will there be room to put the runtime and standard lib on a diet 📏 if they are too big to fit into a Uc's flash (ROM)?

i think this one : https://github.com/JetBrains/kotlin-native/pull/365/files

I'd like to have a common source set for both a JVM library and a KLib, but I'd like the JVM library to have nice Java Interop so I have a few

@JvmStatic

and

@Throws

annotations thrown in there. These are however giving me

error: Unresolved reference

in the compileConan task. Anyone got suggestions for how to deal with this with a common codebase? I thought maybe I'd create typealiases to dummy annotations for these in the Kotlin/Native library. But then I don't know how to deal with the annotation argument for Throws... (KClass also doesn't exist for Native). edit: (using the Konan Gradle Plugin)

but as soon as I add plugins { konan } I get "build.gradle.kts165: Unresolved reference: konan"

Hi kotliners! Will be possible to use Kotlin/Native for Arduino (or some other microcontrollers)? Is it in consideration? Thanks for answers.

Question: Can Kotlin native generate C header files so that kotlin can be called as a library by C code?

Does Kotlin Native allow access to the stack?

Porting libs that depend on the JDK unchanged. Scala native supports that and I was wondering if Kotlin native would to.

But uCs almost always have some sort of posix lib with a layers you implement for the platform.

And linkers should strip unused code like proguard does on Android

For now Kotlin/Native generates order of magnitude bigger and slower code compared to plain C equivalent.

So anyway it is not usable for Ucs with a few kilobytes of memory. For bigger devices with tens of megabytes and embedded linux - well, why not.

I could use inre error handling in kotlin native. I'm trying to enumerate the contents of a directory with

readdir

from

dirent.h

. I have the following code:

while (true) {
                    val ep = readdir (dp)
                    if (ep == null) break
                    val str = ep.pointed.d_name.toKString()
                    println(str)
                }

This works for some dirs but not all. On some, I get the following partway through the enumeration:

terminate called after throwing an instance of 'utf8::invalid_utf8'
  what():  Invalid UTF-8

The execution terminates immediately. How do I catch/recover from this error? I've tried wrapping with try/catch Throwable to no avail.

I mean, remembering that fortran doesnt have exception semantics, what can I do when it invokes a language that does?

Kotlin Native integrates with LLVM, LLVM can target the AVR microcontroller... size-wise, what is the chance of compiling (very simple) Kotlin for a target as small as an 8-bit AVR? Is there too much dependant bootstrap code even for the most simple 'hello world' or is this possible?

I will try.

if your device is connected i believe it'd need relatively big memory to receive data from internet, i don't think making something to blink is a real world usage

what exists for native implementation to instrument method calls and functions?

does it have some bindings etc

any news about the incoming ide?

I’m curious. Gradle just published big blog post about future of native build support. https://blog.gradle.org/state-and-future-of-the-gradle-software-model They deprecated Software Model and will continue evolution of native build support with current build model. I know, that kotlin-native has own plugin and not related somehow to Software Model. But it would be nice if kotlin-native plugin would be compatible with new Gradle plugins for cpp and swift and some upcoming features of other native plugins on Gradle
