Can I kotlin-native compile a Maven project with all its dependencies? (mac OS X)

Hi guys, I’m receiving the following error in my build process.

error: compilation failed: Could not find "/Users/travis/build/my_project/application/native/wasm/build/klib/kotlinx.interop.wasm.dom-jsinterop.klib" in [/Users/travis/build/my_project, /Users/travis/.konan/klib, /Users/travis/.konan/kotlin-native-macos-1.1.2/klib/common, /Users/travis/.konan/kotlin-native-macos-1.1.2/klib/platform/wasm32].

But this error is only happening on the CI and not in my development machine. The strange thing is the same error is also happening in appveyor and circleci too. Does someone knows a workaround for this?

I started to do a little proof of concept today to see how well Kotlin Native objects would behave when being scripted from Javascript. I quickly hit a wall when I noticed that the

.def

file for

JavaScriptCore

is disabled. Does this not work at all? Or was it disabled a long time ago and nobody had checked it out since?

hey folks trying to do this in MPP (iOS):

actual constructor(longVal: Long) {
        delegate = NSDecimalNumber(longVal)
    }

Getting error about ambiguity, looking into the bindings see 2 constructors that looks identical:

@kotlinx.cinterop.ObjCConstructor public constructor(long: kotlin.Long) { /* compiled code */ }

@kotlinx.cinterop.ObjCConstructor public constructor(longLong: kotlin.Long) { /* compiled code */ }

Is it a bug, or there something I missing?

is there a good explainer around on the difference between the

kotlin-multiplatform

plugin and the

kotlin-native-platform

plugin and when to use each?

also, can anyone explain why i was able to build with coroutines by setting gradle to 4.10.1 and using

enableFeaturePreview('GRADLE_METADATA')

, but not using gradle 5.1, which theoretically has that built in? (I will accept “gremlins” as an answer at this point)

what is the difference between

kotlin.native.concurrent.Future.result

and

kotlin.native.concurrent.Future.consume(code: (T) -> R))

. Seems like both are blocking, will block caller. I was assuming from API that

Future.result

- suppose to be blocking but

Future.consume(code: (T) -> R))

non blocking as it takes lambda.

Hello i've tried the project from here https://kotlinlang.org/docs/tutorials/native/mpp-ios-android.html, i understood that build generate a jar file for android and a framework file inside bin folder for ios but i only get the jar file when building with android studio how can i generate the framework file then pleaz?

I used this command from tutorial “kotlinc-native -target android_arm32 -output hello_android.cgi hello.kt -e sample.main” it gave me *.so file. But on Android I wasn’t able to run it from console. It said “Illegal instruction”. Unlike for mac it generated console executable successfully

In this post (https://superkotlin.com/kotlin-and-webassembly/) they say if we would like a full support to kotlin native wasm32 we should be using CLion. Is there a plugin on IntelliJ Ultimate so I could achieve the same result? I don’t know if I have all tools instaled and I would like to check.

I’m working on some tests for something that executes asynchronously. Is there a

runBlocking

coroutines version that works in a

commonTest

for a multi-platform project?

Hello everyone, My build is failing here

org.jetbrains.kotlin.konan.library.resolver.KonanLibraryResolverKt$TopologicalLibraryOrder$1$1.invoke(KonanLibraryResolver.kt:40)

and I would like to inspect the code with breakpoints. Does someone knows how can I debug my konan build in IntelliJ? Where I’m using something like

./gradlew build

for now and all of my build scripts are

.gradle.kts

ones

It might be a strange question, but I will shoot it anyway. When it’s “safe” to use

TransferMode.UNSAFE

for

Worker

transfer mode? Can we say if we are 100% sure that no one is going to mutate the thing we passed from the producer to the job, then it’s ok to use unsafe mode (and avoid freezing)? And second question what consequences to expect if smth goes wrong? (one thing I can think about is mem corruption issue, is there anything to watch out?)

How often does the Kotlin/native compiler IR change, and how significantly? I'd like to use it at compile time to inspect classes that have a specific annotation, and then generate a separate wrapping class for them. Would I find any gotchas with the IR?

I’m working on some native platform coding. I have a local build of native branched at 1.1.0 release. Is there a way to config a multiplatform build to point at my local version?

To what maps in Obj-C

abstract class

? Can't find it in

OBJC_INTEROP.md

If I submit multiple requests to a Worker, it appears that the worker will only process a single request at a time. Is that correct? This is a fairly large restriction given that this is the primary method to move data between threads. Especially when I consider that I'd like to receive requests with coroutines, and those coroutines could end up suspending, and I'd like the worker to be doing other things during that time. Do I have the wrong frame of mind, or is there a better way that I should be approaching this?

In the context of freezing, does a lambda have a sub graph? Does freezing a lambda freeze its captured state?

Hey! Is it possible to create an

CPointer<BooleanVar>

without the use of the nativeHeap? I would like to create one on the stack, but everything i've tried failed. Currently im using this

val flag = nativeHeap.alloc<BooleanVar>(); flag.usePinned { it.get().ptr /* <- CPointer<BooleanVar> */}

Hey guys, trying to create Rx bindings for iOS/Android. How is it possible to call custom Swift code from Kotlin(trying to call my own custom Swift classes with RxSwift inside)? Couldn't find any samples of calling custom Swift code from Kotlin, it is stated that you can do it using the @objc annotation and C-interop... Any help/info would be appreciated

hey, I am using kotlin

1.3.30-eap-11

and I have a multiplatform project that used to build just fine with

1.3.21

and now I have this exception during the link phase for iOS framework creation:

e: Compilation failed: lateinit property parent has not been initialized

. I looked in my entire source code I do not use

lateinit

and I do not have a variable named

parent

. I suspect this an error from the kotlin native source code itself. I’d like to know if there is a workaround I could try?

Hi! Any recommendations on providing overrides to methods that are not exposed from Kotlin Native? I’m trying to subclass a UIView and override sizeToFit right now, but it appears like this is purposefully not allowed. Is there a recommended work around for this?

Once ABI and Module stability land in swift, is there any plan to use swift headers for iOS frameworks generated by native, or are they too dependent on Obj-C runtime features? Partly wondering because there isn’t really a great equivalent in ObjC to

enum class

and I want that

switch

functionality I could get in a swift

enum

How do I initialise a variable inside an Object class that I need before doing requests? For doing the following:

AnalyticsConfig.init().baseUrl = "<http://192.168.85.16:8000>"

I get the following error:

Uncaught Kotlin exception: kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen com.analytics.core.helper.AnalyticsConfig@94d888

Here is the class itself:

object AnalyticsConfig {
    lateinit var baseUrl: String
}

What’s the best way to inspect a linker stage? I tried this:

fromPreset(presets.iosX64, 'ios') {
            compilations.main {
                kotlinOptions.freeCompilerArgs = [
                    '-Xlist-phases', 
                    '-Xverbose-phases=ObjectFiles', 
                    '-Xverbose-phases=SetUpLinkStage', 
                    '-Xverbose-phases=Linker']
            }
        }

but not sure if I’m supposed to see something

Given that K/N does not support traditional concurrency model, what are my options for multiplatform parallelization? I fail to see how this design decision can be a good one when multiplatform is added to the frame. It's held me back from using K/N seriously. If someone has an answer, enlighten me please.

Is there a way to provide a Dispatcher.Main in native? Comments seem to indicate that on native, we should provide one, but I'm not seeing how to do that (i.e. where we would create and pass it to coroutines)
