I'm not sure where to report this. I keep getting

error: compilation failed: C:\Users\Dominic\KotlinNativeProjects\kotlin-sqlite\build\konan\libs\mingw_x64\ksqlite.klib: The process cannot access the file because it is being used by another process.

, when I build Kotlin/Native project in CLion. Can only fix it by restarting.

What version of Kotlin are we going to see a compiler plugin API that is public across all Kotlin compilers?

I have clion with the latest Kotlin/native plugin but can't get the idea to give any completion information

Anybody explain me how to handle mutable singletons in common module. Here is the changes that I add into kotlin-mpp-example: https://github.com/KamiSempai/kotlin-mpp-example/commit/35627af6d4d3e1e0b7824adb708e9e0906db4a3c I add a new one object Factory2 in common module that has lazy initialization of its properties. On android it works fine but in iOS i get InvalidMutabilityException. Ok, I know that in Kotlin Native all singletons are freezed and I should use annotation ThreadLocal to make it mutable atleast in one thread. BUT this is common module. I can't use anything from Kotlin Native. Does any practices that helps to solve such problems in common modules? Right now I only see that this immutability cut a lot of code which can be moved into common module.

Can I tie a StableRef to a MemScope so that it gets disposed automatically when the MemScope ends?

Is there a way to bind native object lifetime to a kotlin object?

I got: warning: inliner failed to obtain function declaration: kotlin.properties.Delegates.observable Is it a problem?

Can anyone who can be bothered, explain why my Virtual Table test works on Linux(WSL) but not on Windows? It ends with

Process finished with exit code -1073741819 (0xC0000005)

I think it might be a linking issue but I'm not experienced enough to figure it out. https://github.com/Dominaezzz/kotlin-sqlite

I’ve tried building my kotlin native project using Xcode 10 GM and I’m getting a compilation error:

targeted OS version does not support use of thread local variables in _kfun:com.TestEnum.$OBJECT.$get-VALUES()kotlin.Array<com.TestEnum> for architecture x86_64

* What went wrong:
Execution failed for task ':platform-ios:compileDebugIos_x64KotlinNative'.
> Process 'command '/Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

Anyone know how to solve this?

is it possible to interop with objc/swift code that isn’t platform artifacts? I see info like https://blog.jetbrains.com/kotlin/2017/11/kotlinnative-v0-4-released-objective-c-interop-webassembly-and-more/ to interop with platform libraries like UIKit and Foundation but I’m wondering if theres a way to interop with other framework artifacts or just header files that are part of my source directory? I could have sworn I saw it somewhere…

is there some way to set the component name in the new gradle DSL? before we could do

library('foo')

, but with the experimental DSL it seems to make

components.main.name

read only

I want to know whether kotlin native coroutines are supported in iOS or not. I heard that starting from kotlin 1.3, iOS is supported.

Going back to my problems with types 🙂 Is there any way to have compiled interface to be [UInt8] and not [MyLibInt]? I tried also with val myVal: List<Int>; and in primary constructor: MyClass(myVal: List<Int>), but it still compiled to [MyLibInt]

Hi everyone! I’m trying to run Kolin Native examples and when I run

./gradlew dist crossDist

in root folder of the project, I get:

kotlin-native-master/runtime/src/main/cpp/Interop.cpp:22:10: fatal error: 'ffi.h' file not found
#include <ffi.h>
         ^~~~~~~
1 error generated.

MacOS 10.13.6, XCode 9

One more general question: The situations is that we already have backend and android app written in kotlin. They share a library with a lot of business logic. Now I’m thinking how it would be best to approach iOS app - should we go for including common lib and writing UI, DB and stuff with swift or is it safe to write UI stuff with kotlin too?

So I'm writing an OpenGL Loader generator for Kotlin and each function looks something like this.

private val glShaderSource: CPointer<CFunction<(GLuint, GLsizei, CPointer<CPointerVar<GLcharVar>>?, CPointer<GLintVar>?) -> Unit>> get() = glfwGetProcAddress("glShaderSource")!!.reinterpret()

With another function to call it properly of course. Since, I'm not relying on c_interop to do any magic for me at the border between Kotlin and C. What types are actually allowed at the border? Everything in

kotlinx.cinterop.*

?

I’ve made an example app from a tutorial on github: https://github.com/JetBrains/kotlin-native/blob/master/MULTIPLATFORM.md iOS app works ok, but I can’t find a way to add dependency from maven to be included in my framework. Is there something I’m missing? When I add

implementation

to dependencies, I get an error

Could not find method implementation() for arguments [...] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler

Hi, Is it known problem that latest CLION doesn't see attached interop library to hello world example? (but compiles/run fine) also CLION doesn't show readable compiler/linker errors

Does anyone know when the Kotlin/Native plugin for AppCode will support 0.9? Or is there some preview version to download?

Does kotlin native support coroutine channels? https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md#channels-experimental

I'm trying to write code which maps some Kotlin values into cinteropped ones, and stumbled upon this one trying to process array (for primitives copying values via

output.pointed.value = input

, for structures I was going to copy bytes and needed size of generic

CVariable

). The stuff that breaks:

import kotlinx.cinterop.*

inline fun <reified T : CVariable> sizeOf(value: T) = sizeOf<T>()

fun process(value: Any) {
	when (value) {
		is Int -> 4
		is CVariable -> sizeOf(value)
	}
}

fun main() = Unit

The error:

error: compilation failed: native variable class deserialized class CVariable must have the companion object

 * Source files: sample.kt
 * Compiler version info: Konan: 0.9.1 / Kotlin: 1.3.0
 * Output kind: PROGRAM

exception: java.lang.IllegalStateException: native variable class deserialized class CVariable must have the companion object

Hey! How do I get a

CValuesRef<CPointerVar<ByteVar>>?

to pass to a native function?

Also, what's the current version of Gradle I should be using for Kotlin/native? The last I saw was several versions ago with Gradle 4.7

you MUST use EXACTLY kotlin 1.3-M1 if you are using Kotlin JVM in the rest of your project. no other version works at all, not -m2 not any of the release candidates

which is the recommended ide for developing with kotlin native for ios? I have tried clion 2018.3 eap but unable to find an compatible kotlin/native plugin. It needs to work with mpp.

btw, the above remains true for the currently unreleased 0.9.2 - it doesn't seem to work with the latest 1.3 EAP 😞 (different error though). AFAICT this means I can't easily use Kotlin/Native right now in a project that also uses Kotlin/JVM because the plugins end up interfering with each other, and the IDE has updated me to the latest version of the Kotlin plugin on the EAP. I suppose I could try to downgrade my IDE to -m1 but, eh

Are there any progress for better handling C keywords in Kotlin?

@NativeName

maybe?

How can I include two Kotlin frameworks in an app? I'm getting

Only one Kotlin framework can be loaded currently

. version 1.3.0-rc57
