Hi, everyone. i wrote some kotlin app using cinterop ( tensorflow c api), in intellij. How can i configure debugger? LLDB, for example?

I use K/N in my Android/IOs project. Trying to migrate from

konan

to the new

kotlin-multiplatform

plugin. Is it possible to have MPP library in the MPP project? I created an MPP library using IDEA's wizard, published it in maven local and tried to add to the project. But I have a gradle sync error:

More than one file was found with OS independent path 'META-INF/FooMppLib.kotlin_module'

does k/n support the arm64_32 arch used on the AW series 4? seems to be a required arch when importing a k/n framework into an apple watch extension in xcode 10.

hi everyone, new to k/n i'm trying to open a new project in intellij idea and get this:

Unable to find method 'sun.misc.Unsafe.defineClass(Ljava/lang/String;[BIILjava/lang/ClassLoader;Ljava/security/ProtectionDomain;)Ljava/lang/Class;'.
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)</li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)</li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

i'm on ubuntu 18.10, openJdk 11, latest IDEA, thanks

If you want to pass a pointer, you can use

memScope {
    val size = alloc<UIntVar>()
    sysctlbyname(..., ..., size.ptr,)
    size.value
}

A question about toll-free bridging in iOS. For example when I call

CFBundleGetValueForInfoDictionaryKey

I get an object of type

CFTypeRef?

, but it’s bridged to

NSString *

automatically in Objective C. How do I get a Kotlin string out of

CFTypeRef?

?

will kotlin-native replace kotlin-jvm ?

hey guys, I'm totally new to kotlin/native, but I need it for a multiplatform project. Is there any way to convert a ByteArray to a platform.Foundation.NSData?

question about linking: I have a little (multiplatform) project that builds an iOS framework. That framework has all the kotlin-native stuff linked in (ie the stdlib). I was hoping to make this a multi-module project and build lots of little frameworks. If I do will they all necessarily get their own copy of the stdlib? Is that avoidable in any reasonable way?

ie, I don’t necessarily want all my frameworks to be self-contained, happy to pull the stdlib etc into my consuming projects as a separate framework

When will compile speed / incremental compilation be a focus for kotlin/native?

I'm having a hard time understanding how to implement `getline`'s sample in K/N: https://linux.die.net/man/3/getline (at the bottom)

this may be more of a gradle question, but what’s the right way to define a framework module that rolls up a couple of library modules? source set dependency doesn’t seem right (and isn’t working)

(this is a framework with no source code of its own, it should just be aggregating other modules together for packaging)

I am working on coming up with a non-trivial sample for kotlin on the STM32F4 Discovery board with Zephyr and have encountered a rather interesting issue. Specifically, this code generates a Usage fault in the ARM core of type No Co-processor instructions on line 8 (I presume line 8 because the message on line 7 shows in the console but line 8 does not). I am trying to determine why the build would even generate co-processor instructions in the first place for something like this. As a first pass i modified the konan plugin options to have the additional option

-mfloat-abi=soft

to ensure that any hardware FPU instructions would not be generated but this did not change the outcome. I am trying to track down what the reason for this on such a simple set of code and would be appreciative of anyone who can give me some more insight into the where I can look in konan or its various configuration/native files to perhaps gain more insight.

Why is the Kotlin/native AppCode plugin not supported in the latest version of AppCode?

How can I create String from UTF8 bytes? I found this function

CreateStringFromUtf8

in sources, but I cannot find kotlin function to call it. https://github.com/JetBrains/kotlin-native/blob/4f9cea4ee235b0663b9fb5660e814a49d06b69ed/runtime/src/main/cpp/KString.cpp#L710

Hey does anyone know if TornadoFx works with native?

Does anyone know why konan is configured to use the

target-sysroot-2-wasm

sysroot for the STM32F4 target?

Quick question: does kotlin/native still allocate all objects on the heap or does it take more of a stack based approach like in languages such as Go and only escape to the heap if necessary?

Why have they created a new language construct for this?

Im trying to continue my efforts in getting kotlin floating point working in Zepyhr/STM32F4 and I think my last major hurtle is getting kotlin to compile with the same floating point options as zephyr. I added

-mfpu=fpv4-sp-d16 -mfloat-abi=hard -march=armv7e-m

to

konan/platforms/zephyr/stm32f4_disco

but am still getting a link error of

arm-none-eabi/bin/ld: error: zephyr/zephyr_prebuilt.elf uses VFP register arguments, libapp.a(program.o) does not
/home/jared/.konan/dependencies/gcc-arm-none-eabi-7-2017-q4-major-linux/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/ld: failed to merge target specific data of file libapp.a(program.o)

which suggests to me that the object file being built by konanc is not being built with the correct flags going to gcc. Am I missing something in configuring the build to pass these flags?

hi everybody

I have some question about the iOS part

Hi guys, I’m working at Tencent (one of the largest IT company in China). We are going to develop a commercial SDK for Android and iOS, we want to facilitate code sharing by K/N. One thing concerns us is when will K/N be stable. 🎉

I’m trying to use HttpClient in a multi-platfrom project. When I run an iOS test via Gradle, I get this in the console:

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9807)

I understand that I need to add

NSAllowsArbitraryLoads

into the Info.plist. But how do I do it with Kotlin? There is no

Info.plist

.

do you need to install Xcode on Mac?

does anybody try the ios part of https://kotlinlang.org/docs/tutorials/native/mpp-ios-android.html#creating-ios-application ?

Is it just me, or the kotlin stack traces do not include the line numbers? Is there any way to have the line numbers in stack traces?

kotlin.AssertionError: Expected <108>, actual <107>.
        at kfun:kotlin.Throwable.<init>(kotlin.String?)kotlin.Throwable (0000000000440470)
        at kfun:kotlin.Error.<init>(kotlin.String?)kotlin.Error (0000000000442030)
...

is there a way to use syncronized block in native? ios. there is no @syncronized available
