After upgrading from 1.3.71 to 1.3.72, I get this warning:

The Kotlin/Native distribution used in this build does not provide the standard library.

And soon after, this error which crashes the whole gradle VM:

e: Could not find "stdlib" in [/Users/natario/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].

Does anyone know what this means? I can't see anything relevant in the changelog.

I am trying to export my Kotlin Native Multiplatform project as a shared lib, but I am getting these error messages:

Any ideas what I need to change? Those are all library classes.

How I can setup parameters for MacOS App Sandbox? I have to set

com.apple.security.network.client

to

true

https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_network_client

I cant seem to import

Char.isLetter()

in my common code for multiplatform project. Any help ?

how can i use C functions in stdio such as

getchar()

from KN ?

How to determine which is better…..Lazy variable vs function with some return type…….. in kotlin. As we can use them interchangeably.

Hi, can someone link me up with the upstream tar-file of Kotlin v-1.3.30 I fail to find it.

Hi, I’m trying to use CUrl https://github.com/JetBrains/kotlin-native/blob/master/samples/libcurl/src/libcurlMain/kotlin/CUrl.kt for POST data I’ve added SSL

curl_easy_setopt(curl, CURLOPT_PORT, 443L)
curl_easy_setopt(curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS)

and method POST

fun post(postData: String) {
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headersCRef)
    val cstr = postData.cstr
    curl_easy_setopt(curl, CURLOPT_POST, 1)
    curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "POST");
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, cstr)
    curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, cstr.size)
    val res = curl_easy_perform(curl)
    curl_slist_free_all(headersCRef)
    if (res != CURLE_OK) {
        throw RuntimeException("curl_easy_perform() failed: ${curl_easy_strerror(res)?.toKString()}")
    }
}

But the server accepts wrong data - without some chars (at the start or at the end). What I do wrong? How it can be fixed? FIXED:

curl_easy_setopt(curl, CURLOPT_POSTFIELDS, cstr)

->

_curl_easy_setopt_(curl, _CURLOPT_POSTFIELDS_, cstr.getPointer(MemScope()))

Hi, I'm trying to use KN with ncurses. Is there a way to debug an application from Idea and use a full-fledged terminal? It's not working without terminal obviously.

Any way of getting this to work on kotlin native? For example in Swift I can do:

let label = UIView()
label.frame.origin.x = ...

I cant seem to find where I can update the

x

in kotlin..

When working with cinterop, is it expected that the generated klib and related build files will not be checked-in into vcs?

How config cmake in kotlin multiplatform project? When config as the following DSL in build.gradle

android {

    defaultConfig {
        externalNativeBuild {
            cmake {
                abiFilters  "arm64-v8a","armeabi-v7a"
            }
        }
    }

    externalNativeBuild {
        cmake {
            path 'CMakeLists.txt'
        }
    }
}

kotlin {
    macosX64(){
    }
    linuxX64() {
    }
}

I got an CONFIGURE FAILED error: ABIs [armeabi] are not supported for platform. Supported ABIs are [arm64-v8a, armeabi-v7a, x86, x86_64]. My project structure is shown in the attached image, How can I solve it?

Does anyone have any experience with using KMP to author a React Native module for iOS and Android?

Is there anyway to ensure that unit ISN'T converted into void when exporting as framework for IOS? I've had an issue with higher order functions using Kotlin unit and where their meant to be passed into using void. E.G ((Type) -> Unit, (Type) -> Unit) -> Unit Where those functions would be passed into somewhere that takes (Type) -> Unit as a parameter, in the first part you Unit becomes KotlinUnit and in the 2nd it becomes Void making them incompatible

I tried to use

ktor-client-core

with

ktor-client-curl

(while

ktor-client-cio

isn’t redy). When I build the application I have the error

cannot find -lcurl

I’ve added

libcurl.a

and

libcurl.dll.a

into

%HOMEPATH%\.konan\dependencies\curl\lib\

but it isn’t helped. How can I fix it?

Hey, I have spotted this in my multiplatform project, but I guess it's konanc related. I'm using 1.4-M1 I am using

UByteArray

inline class in my project. linkDebugStaticLinux task fails (rather silently), but running konanc directly with parameters from the task provides the following output (this is just a snippet:

Indicating that

libmultiplatform_crypto_kref_kotlin_ByteArray

is unknown, which is somewhat correct because I am using UByteArray. I worked around this issue by simply declaring one ByteArray in the same class like this

val byteArray: ByteArray = byteArrayOf(0, 1)

And then compilation succeeded. My question is, is this a known bug, or should I report it?

Does anyone know why this code returns false?

fun main() {
    val str = "123test123"
    val matches = Regex("""test""", RegexOption.MULTILINE).matches(str)
    println(matches)
}

Has anyone had any luck obtaining the

NSBundle

for a K/N iOS Framework from within the framework? I’d like to use

NSBundle.bundleForClass(ObjCClass)

however this seems to return the Application bundle. If I call

Bundle.init(for: ClassFromFramework.self)

in Swift I get the right bundle.

Hi all, I am pretty new to Kotlin native. Is it possible to write hardware software with Kotlin native?

Building kotlin-native again. Master this time. Running into the following error.

fatal error: module 'AutomaticAssessmentConfiguration' not found

Wondering if anybody’s seen this.

Will there be a memory leak if both a Swift object and a Kotlin object have strong references to each other?

Can anyone explain what

kotlin.native.ImmutableBlob

is and how to use it?

Hey guys. How do I say Kotlin/Native to link my cInterop library to link against the C++11 standard library ? I'm having a whole lot of

undefined symbol: std::__cxx11::basic_string...

error at linkage. My library is a C interface to some OpenCV features. I have

libopencv-dev

installed on my computer. Because my C wrapper transforms

const char*

into

std::string

, I can't compile my it with

-D_GLIBCXX_USE_CXX11_ABI=0

(then I get undefined symbol errors on all OpenCV method I use that takes a

std::string

because the ABI is different). The only solution I see is to download and re-compile OpenCV and all its dependencies with

-D_GLIBCXX_USE_CXX11_ABI=0

, which is an enormous hassle. Is there a way to instruct the Kotlin/Native linker to link against the C++11 standard library ?

How can I call Windows api such

GetVersion

,

GetSerialNumber

? I have not found these functions.

Is there a known issue that

ensureNeverFrozen()

does not generate an exception or not caught on ios?

When exporting my project as a dynamic library I have this line in my header file:

typedef float __attribute__ ((__vector_size__ (16))) nimmstaWindows_KVector128;

This is not valid code. Any idea how to fix this other than to manually delete it?

Anyone had any luck subclassing UICollectionView? I’m having trouble making it have the height of its content size. Already tried so much stuff that I don’t really know what I could do more.

hi i was making chatbot with https://www.api.ai/ and test it in intellij idea and it works fine and i want to deploy it in microcontroller (arduino, rasberrypi, BeagleBone, Sharks Cove, Minnowboard MAX, Nanode, android things ..............) but i don`t know which microcontroller is compatible with kotlin . which is ? 🤔

Do we have a single kotlinx library which consists of all the kotlinx.* ?
