Has anyone had any luck consuming a pod through cocoapodsext? I’m attempting to use

TensorFlowLiteC

and/or

TensorFlowLiteObjC

from my

iosMain

but when I build in XCode it always complains about undefined symbols when linking. For example, adding

pod("TensorFlowLiteC")

to the KaMPKit Starter and adding

println(TfLiteVersion().toKString())

to the

initKoin {}

block in

KoiniOS.kt

results in

Showing All Messages
Undefined symbols for architecture x86_64:

  "_TfLiteVersion", referenced from:

      _cocoapods_TensorFlowLiteC_TfLiteVersion_wrapper17 in result.o

ld: symbol(s) not found for architecture x86_64

when building in XCode (from the gradle output) I’m stumped as to what to look into next.

It's happening https://blog.jetbrains.com/kotlin/2020/07/kotlin-native-memory-management-roadmap/

What are the current approaches that one can use to generate a .framework, from kotlin/native, and distribute it to be consumed by third party iOS developers (with objc/swift)? Is the podspec, generated by the cocoapods plugin, a good fit for this scenario? Or would it be better to have an xcode project whose sole purpose is to generate the final .framework, assuming that it will be built entirely with kotlin?

Any plans for a RISC-V target?

Hey guys, I'm trying to implement a TCP connection on iOS using Network.framework. To open a simple TCP connection, I'm supposed to call:

nw_parameters_create_secure_tcp(
    NW_PARAMETERS_DISABLE_PROTOCOL,      // No TLS
    NW_PARAMETERS_DEFAULT_CONFIGURATION  // Default TCP config
)

However, iOS gives me a very weird error:

_nw_parameters_configure_protocol_disable_block_invoke _nw_parameters_configure_protocol_disable called directly, dumping backtrace:

My cinterop task fails with:

e: Could not find "library" in [/Users/natario/Projects/project/project-name, /Users/natario/.konan/klib, /Users/natario/.konan/kotlin-native-macos-1.3.72/klib/common, /Users/natario/.konan/kotlin-native-macos-1.3.72/klib/platform/android_arm64].

But nothing I have is called "library", does anyone have any hints? If I run the task with --info I can see the command that is failing (it's huge, but this should be the core part...

...kotlin-native.jar org.jetbrains.kotlin.cli.utilities.MainKt cinterop -o...

). None of the arguments to this is called "library", I just see some

-library <http://path.to|path.to>.klib

which are the libraries that are being cinterop-ed.

Will the concurrency limitations will be lifted in the current ARC style memory manager, or will we not get java-style concurrency until the new memory model comes out?

Are there any plans for K/N to support python interop? Or maybe it's already possible? Just wondering as it'd open up kotlin to data science

Hello. I write kotlin library for sqlite. I want to build sqlite from source before build kotlin native part of library. How can I get access to konan gcc path? Current path for current build target.

How can i safely pass long from c to kotlin as int ir int array and then safely convert it back to long on kotlin?

Any way to compare two lambdas to determine if they're equal (when they have been constructed separately with the same builder)

So with KN

1.4.0-rc

, the compilation of our project after a single line change has significantly increased, from 30-40secs in

1.3.71

and to

3mins+

in

1.4.0-rc

. It looks like it's doing a full build every time.. Does anyone have the same experience?

Is it known regression in cinterop?

libui

have opaque pointers, say

typedef struct uiArea uiArea;

Previously it was impored as

typealias uiArea = CPointed

And now (in 1.4.0-rc) it is just missed in output of

klib contents ...

, and so not available by Ctrl-B in IDEA, and inspection by F2 complains "Cannot resolve symbol 'uiArea'".

Can somebody see what makes my cinterop setup break since 1.4-M3? It is still broken for all targets in 1.4.0-rc. It fails with:

Exception in thread "main" java.nio.file.NoSuchFileException: libobjectiveRocks-macOS.a

I’m using the cocoapods gradle plugin, 1.4.0-rc. I took the kotlin-with-cocapods-sample library, added in my own source code and podspec file. When I sync the project, the build fails when

xcodebuild -project Pods.xcodeproj -scheme Boulangerie-iOS -sdk iphoneos -configuration Release

is executed. It’s not finding all the header files. Error: “fatal error: ‘com/dough/profitability/calculation/Zoner.h’ file not found”. Relevant part of the podspec:

s.preserve_paths = "ios/src"
  s.header_mappings_dir = "ios/src/objc"
  s.public_header_files = "ios/src/objc/**/*.h"
  s.source_files  = "ios/src/objc/**/*.{h,m}"
  s.resources = 'ios/src/resources/**/*'

  s.dependency 'J2Objc', '~> 2.6' 
  s.dependency 'AFNetworking', '~> 4.0.1'

  s.xcconfig = {
      'HEADER_SEARCH_PATHS' => '"${PODS_ROOT}/Headers/Private/Boulangerie-iOS"/**'
  }

Anyone know how I can get this to work?

Hi everyone! Does someone know how to increase build time for real iPhone. Now my build takes about 10 minutes and it's so slow.

Is it possible to publish sources for native targets? Something like x-sources.jar for IDEA to pick up

Hi all! I'm just starting to play around with Kotlin Native for a command line utility tool. I'm trying to figure out how to make a

fork

system call but I don't think the

fork

function is available. However, I see it being mentioned in the below SO posts. Is there something I'm missing? https://stackoverflow.com/questions/57190228/using-kotlin-native-how-can-i-execute-an-external-os-executable-or-path-comman https://stackoverflow.com/questions/51460921/kotlin-native-execute-an-executable

I try to use fopen function in mingw. When fileName is ANSI string it works. But when fileName contains non-ansi symbols (cyrillic etc) I have a problem -

can't open file

For C I've found the solution -

OemToCharA

function but it doesn't work for me

fileName = memScoped {
            val bytes = allocArray<CHARVar>(aFileName.length * 2)
            OemToCharA(aFileName, bytes)
            bytes.toKString()
        }

fileName contains wrong chars

Sounds like subclasses of NSObject are automatically frozen:

class TestNsObj: NSObject() {
    init {
        println("is frozen: $isFrozen")
    }
}

fun runTest() {
    val a = TestNsObj()
}

output: is frozen: true Couldn't find any official info about that. Do I miss smth? Btw if I remove subclassing from NSObject the object is not frozen.

It seems the mpp plugin publishes 3 different maven artifacts. Why is that and on which one should I depend in my application?

I’m working on testing the 1.4.0-RC for a library, and I’m getting:

e: Could not find "posix" in [/Users/[user]/Developer/IdeaProjects/kgl/kgl-glfw, /Users/[user]/.konan/klib, /Users/[user]/.konan/kotlin-native-prebuilt-macos-1.4-rc1-40/klib/common, /Users/[user]/.konan/kotlin-native-prebuilt-macos-1.4-rc1-40/klib/platform/macos_x64].

I checked in the klib directory, and in 1.3.72 there is a “posix” folder inside

~/.konan/kotlin-native-macos-1.3.72/klib/platform

, and in 1.4.0-RC, that folder is called “org.jetbrains.kotlin.native.platform.posix”. Anyone know what’s going on there? I’m working with the new hierarchical mpp setup if that makes a difference

How to get currentTimeMillis on K/N?

Is there a gradle command to refresh sourceSet dependencies with

kotlin.mpp.enableGranularSourceSetsMetadata=true

Could someone with mac or Windows kindly check if this kotlinx-html expansion resolves on their native projects targeting said platforms?

Is there a way to prevent the dependency tarballs in the

.konan/cache

directory from being deleted, like a Gradle property of some sort? This is for CI, where caching the tarballs directly and unpacking them each time would be optimal.

Hello, is it possible to use two Kotlin/Native frameworks in a single iOS application?

Hi there, I'm trying to do some network request with
