if a lambda captures a class member, and the lambda is frozen, why does it need to freeze the member's parent object?

Is there a way to convert Worker to coroutineDispatcher/Context? I need to ensure that the callback from coroutine job is executed on the same thread that launched the coroutine

Does anyone know why the mt version of DroidconKotlin has the

CoroutineScope

moved to a separate class? See the following: https://github.com/touchlab/DroidconKotlin/blob/kpg/mt_coroutines/sessionize/lib/src/commonMain/kotlin/co/touchlab/sessionize/BaseModel.kt If you check the master branch than you can see that

BaseModel

just implements

CoroutineScope

. In the

kpg/mt_coroutines

branch that implementation was moved to a separate class, called

MainScope

. Is there a reason behind this change to support mt coroutines? Is it possible that

MainScope

can become frozen for some reason?

Anyone experience this and find a solution? It seems easy to fix, but I’ve already checked and my Kotlin Gradle plugin is set to 1.3.61. Tried invalidating caches/restarting but it didn’t fix anything.

10:06 AM	Incompatible Kotlin/Native libraries
				There are 227 libraries from the Kotlin/Native 1.3.50 distribution attached to the project: stdlib, ARKit, AVFoundation, AVFoundation, AVKit, ...
				These libraries were compiled with an older Kotlin/Native compiler and can't be read in IDE. Please edit Gradle buildfile(s) to use Kotlin Gradle plugin version 1.3.61. Then re-import the project in IDE.

Any way to implement

deinit

in Kotlin on iOS? I guess not but you never know

I posted this in #multiplatform but deleted the post since I think this is the more appropriate channel because it’s more of an iOS Kotlin Native issue: Hi all, I’m currently running into an archiving issue with an iOS app using a framework created from Kotlin multiplatform with the FatFrameworkTask. Previous versions worked and the iOS app has live builds with the framework, however, in the latest attempt to create a new Testflight build where I upgraded the following dependencies in the KMP project:

const val kotlin_version = "1.3.61" previously "1.3.40"
const val coroutines_version = "1.3.3" previously "1.3.40"
const val ktor_version = "1.2.6" previously  "1.2.2"
const val serialization_version = "0.14.0" previously "0.11.1"
const val mockk_version = "1.9.3"

The framework is created. The app works in debug mode. The issue is strictly archiving. I’m running into this issue:

Has anyone encountered this issue? I’m quite sure it’s related to the changes in the KMP project because reverting the framework (via cocoapods) to the previous version results in a successful archiving. The minimum target for the app is iOS 10.0 so a 32 bit architecture is supported

I'd like to use the bitcoin library (which is C++) in Kotlin. Is there a way to do this (via Interop?)? https://github.com/bitcoin/bitcoin Ideally I would like to be able to call it from common code in my Kotlin Multiplatform project eventually. Other "option" would be porting the complete library, which is not feasable both in amount of work as in efforts to maintain/sync with original code.

Hi all, does anyone know the best way to create and distribute a KN binary - without source - that’s consumable for iOS developers? Preferably via Cocoapods?

From https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.native.concurrent/-atomic-reference/value.html

The referenced value. Gets the value or sets the new value. If new value is not null, it must be frozen or permanent object.

What is a permanent object? I have not seen that language used elsewhere before

Hello, we’d like to use Filament (google’s renderer) on both platforms (Android and iOS). Is it correct we should use cinterop to create a filament.klib and use that? Or is there already something else out there to ease the process?

Is there a way to instantiate an object of a certain class using reflection in K/N? Sadly looks like

KClass.constructors

is only available in JVM/JS

What is multiplatform maven repository URL for kotlin-dev channel ?

Not directly related to K/N, but could someone tell me how to set

background-colour

to GTK3 button? Preferably with inline css (no .css files)

Also, how can i create a common

KotlinNativeSourceSet

with cinterops?

I have some problems with cinterops. I’m trying to add this to my iOS project: https://material.io/develop/ios/components/textfields/ My def file is like this:

depends = Foundation
package = framework.MaterialTextFields
language = Objective-C
headers = MaterialTextFields.h MaterialTextFields+Theming.h

compilerOpts = -framework MaterialComponents
linkerOpts = -framework MaterialComponents

My problem is that when I run cinterops I get this error:

Exception in thread "main" java.lang.Error: /Users/ribesg/XcodeProjects/events/Pods/MaterialComponents/components/TextFields/src/Theming/MDCTextInputControllerFilled+MaterialTheming.h:15:9: fatal error: 'MaterialComponents/MaterialContainerScheme.h' file not found

I found that

MDCTextInputControllerFilled+MaterialTheming.h

contains this line

#import <MaterialComponents/MaterialContainerScheme.h>

and cinterops does not seem to understand it properly. I do have this

MaterialContainerScheme.h

file in the context but it’s not in a folder/module/whatever called

MaterialComponents

I guess. How do I make this work?

anyone have success fixing cinterop IntelliJ autocomplete/index issues? I have cinterops setup and building fine, but none of the symbols show up in the index.

kotlinx.cinterop

imports are also red

I wanna use 1.4.0-dev compiler in intellij, I tried changing multiplatform to 1.4.0-dev-NNNN. it changed libraries to 1.4.0-dev but compiler is 1.3.70-dev. why ?

How do you see the actual cinterop errors when you run into

fatal error: could not build module X

because it's finding an error and failing

org.jetbrains.kotlin.native.interop.indexer.UtilsKt.ensureNoCompileErrors(Utils.kt:146

?

Anyone have a mac I can borrow? I just want to see if a K/N repo can build and run without issue. (Can't see GUI in GitHub actions 😞)

Are there plans for a Linux ARM version of the Kotlin Native compiler (one that will run on a Raspberry Pi for example)? Been having one headache after another with trying to cross compile on a Linux x64 PC for a Linux ARM v7 device (a Raspberry Pi via the linuxarm32hfp target). Would be significantly easier to compile directly on a Linux ARM v7 device if the Kotlin Native compiler was available.

How should i handle interfaces when I export a KN project as a c library? If my function expects a property of a certain interface it does not allow me to cast the property I need to that interface. Is there another way that I have overlooked?

Also another problem I am noticing now: The HashMap type has no definition in the header file. Do I have to call those functions blindly or why are they not exported?

I'm waiting for java independent Kotlin compiler

In keynote @abreslav said 1.4.0 more about performance. That's cool. I don't know why but I like that guy. Right now release build performance is nearly same as C. And in 1.4.0 it gonna more fast. That's awesome.

Is it possible to dynamically select a def file during the build process based on the target?

Somewhat perplexed by the error messages from the Kotlin Native compiler when trying to build a KLib that targets linuxArm32Hfp. Below are the errors:

e: /home/napperley/repos/gui_vista/guivista-core/src/linuxX64Main/kotlin/org/guiVista/core/gobject_utils.kt: (37, 12): Type mismatch: inferred type is gulong /* = UInt */ but ULong was expected
e: /home/napperley/repos/gui_vista/guivista-core/src/linuxX64Main/kotlin/org/guiVista/core/gobject_utils.kt: (52, 38): Type mismatch: inferred type is ULong but gulong /* = UInt */ was expected

Appears as though these are the only compile errors. Seem to be close to building the library for the linuxArm32Hfp target. Are there some subtle differences with data types between arm32hf and x64 I should be aware of with Kotlin Native?

My last question in slack channel. "Is it GOD level required to get 1.4.0-dev builds in IntelliJIDEA ??" Cause right now I'm feeling this. Outside IntelliJIDEA everything complies well with git downloaded builds. Lookes like IntelliJIDEA need to reach sage mode or supersain level. I wasted my 4 days in getting 1.4.0 on IntelliJIDEA. (Dumb IDEA)

If I have a KN library code that uses coroutines and I want to call that code for example from C, how would I initialize the event loop? Right now I am getting this error:`kotlin.IllegalStateException: There is no event loop. Use runBlocking { ... } to start one.`

Has anyone ever tried reimporting a sharedLib using c interop? I tried to but ran into the issues shown in the picture.
