kotlix.serialization compilation fails on custom serializer with

error: compilation failed: org.jetbrains.kotlin.ir.declarations.lazy.IrLazyFunction@550c973e

 * Source files: Sample.kt, SampleIos.kt
 * Compiler version info: Konan: 1.0.2 / Kotlin: 1.3.0
 * Output kind: LIBRARY

exception: java.lang.IllegalStateException: org.jetbrains.kotlin.ir.declarations.lazy.IrLazyFunction@550c973e
        at org.jetbrains.kotlin.backend.konan.llvm.LlvmDeclarations.forFunction(LlvmDeclarations.kt:44)

should I file bug to #kotlin-native or to #serialization ?

I have a param of C function with reference to reference

**variable

(this type generated by interop:

CValuesRef<COpaquePointerVar>

). So in C you pass reference to this reference (like

&variable

). How can I do this in K/N?

So, debugging. What are people doing to debug native code? Specifically I have either command line tests running on a mac or a framework running inside an ios app. My "debugging" is currently log statements. That round trip is pretty terrible. Something better? lldb or similar?

Any CLion Users in the channel who have used it for code coverage and would care to give a clue on how a CLion newbie can leverage the tool while Kotlin Native has no support for code coverage? @msink

does anyone have an example of how to call Ktor from the commonMain? everything i find is for kotlin android, or js

let me ask in a different way. is there a simple sample of something making a network call in Kotlin Native? i would assume this would be done from commonMain

Is there a way to force the compiler to bundle the definition to

Kotlin_Int_plus_Int

into the bitcode file?

this may be a dumb question, but I created a KN class that has 2 functions: one is a regular

fun

and the other one is a

suspend fun

, which is using coroutines to make a network call. on android, i can see both functions from this class. i can call them, and life is good. on ios, I can only see the function that is a regular

fun

. the

suspend fun

is not visible at all. what did i miss? does iOS not support suspending functions from coroutines?

it looks so:

elect@elect-NUC8i5BEK:~/CLionProjects/kotlin-native-opengl-tutorial$ ls /usr/include/GL/
glcorearb.h   glext.h       gl_mangle.h   glu_mangle.h  glxext.h      glxint.h      glxmd.h       glxtokens.h   wglew.h

@svyatoslav.scherbina, why?

A high interest topic for me is code coverage support for Kotlin multiplatform, especially native targets. Understandably, there is a dearth of information about JB roadmap plans for native code coverage tools. If I have this wrong I would love to hear it. So that leaves me with standalone solutions for now, like gcov and related tools, of which I know next to nothing having been focused on JVM since ’95. While I did do C and C++ for a number of years, code coverage did not cross my radar until a few years ago and since then it has been all Jacoco which has it’s own set of issues for Kotlin/JVM. So I’m looking for guidance on how to leverage available code coverage tools with the Kotlin/Native compiler. For example, am I limited to tools that support LLVM? Is there a way to hook into GCC/gcov? Feel free to respond in #code-coverage or a thread here.

so, I tried to create a glfw helloWorld https://github.com/elect86/glfw,

cinterop

is fine, but when it's time to build:

I'm trying to export some classes defined in a k/native framework (defined using new-mpp) on iOS target to a consuming swift project. If I just define a simple class

class Foo

, this gets added to the generated

.h

and seems to work fine. It seems like if I try to subclass an objective c class, such as

class MyViewController : UIViewController

, the symbol disappears from the

.h

and then swift can't see it. Is this expected behavior? Am I missing something here?

does kotlin native support primitive (int, long, float...) arraylists without boxing?

Am I doing something wrong or

initWithTimeIntervalSince1970

is really missing in K/N? I see only

initWithTimeIntervalSinceReferenceDate

I'd like to get some clarification on AtomicReference and memory leaks. In the code comments it says we should null out references to make sure they don't result in leaks, but it seems like they won't always result in leaks. Curious about details. The atomicLazy comment seems to imply cyclic references https://github.com/JetBrains/kotlin-native/blob/master/runtime/src/main/kotlin/kotlin/native/concurrent/Lazy.kt#L115. The Atomics.kt comment just says you should null them out without much detail. While I'll also try to construct shared structures to null out data, if the problematic situations were clear, it would be easier to not have to do that. Thoughts?

If I place a folder called 'aes' in the same directory as the file 'libaes.def' containing this:

package = aes
headers = aes/aes.h
headerFilter = aes/aes.h

Why does my multiplatform solution upon build give me this exception:

Exception in thread "main" java.lang.Error: /var/folders/60/htq84d4s4q55l9j0j1mh6d5w0000gn/T/tmp8457509487070388280.c:1:10: fatal error: 'aes/aes.h' file not found

Does IOS coroutines

delay(x)

not working? trying to create loop thread with

runBlocking{
            GlobalScope.launch {
                  while(flag){
                  //some stuff
                 delay(1000)
                  }
             }
}

and it drops with error

kotlin.IllegalStateException: Cannot schedule task because event loop was shut down

on delay, we are researching atm send help))

@ilya.matveev looks like title should be 1.3.11: https://github.com/JetBrains/kotlin-native/releases/tag/v1.0.3

just two annoying things: no auto completition on Idea and no hightlighting on Clion, https://github.com/elect86/glfw Am I doing anything wrong?

The docs are terrible around getting started with a project in kotlin native btw 😞

Was there a change to way memory leaks are found? After upgrading to

1.3.11

, I now occasionally get this message at the end of my program "C:\BuildAgent\work\4d622a065c544371\runtime\src\main\cpp\Memory.cpp:1150: runtime assert: Memory leaks found"

Any idea when the fix for this issue will make it into release? https://github.com/JetBrains/kotlin-native/issues/2343 It was committed to master, but 1.0.3 doesn’t seem to include the fix.

I have a list of questions that are reserved for the upcoming Kotlin Native webinar: 1. Is there anything in Kotlin Native that will make it easier to handle C libraries that heavily use RC (Reference Counting)? 2. Will any tools/libraries be made available for collecting/extracting meta data from KLibs? 3. Are there libraries available for generating Kotlin source code via Kotlin Native? 4. Is there going to be an option to turn off the Cyclic Collector GC and use Weak References instead? 5. What general performance improvements will be included in future Kotlin Native releases?

is there is a possibility to add IOS library into k/n project? for example, I want to use socket.io. Can I write wrapper for common module and use external library to provide actual code?

Is there any possibility to increase the stack size of kotlin native programs?

Is the bit code output format the same one that Apple is using or is it different? If I could put a Kotlin app on the Apple Watch or tv that would be awesome.
