BTW, are there any support for unsigned bytes in K/N? I had to "upcast" bytes to ints to be able to work with them properly...

Using CZMQ latest from github.

This is similar to where I got stuck yesterday

@olonho New problem is the stubs seem to be generated empty.

@olonho With this def file

headerFilter = czmq.h czmq_prelude.h czmq_library.h zactor.h zarmour.h zcert.h zcertstore.h zchunk.h zclock.h zconfig.h zdigest.h zdir.h zdir_patch.h zfile.h zframe.h zhash.h zhashx.h ziflist.h zlist.h zlistx.h zloop.h zmsg.h zpoller.h zsock.h zstr.h zuuid.h zauth.h zbeacon.h zgossip.h zmonitor.h zproxy.h zrex.h zsys.h

It generates empty bindings

Okay got it working now. But one other issue

I discovered a difference between Kotlin/JVM and Kotlin/Native (on Raspberry Pi) behaviour and I’m not sure if I’m misusing

also()

to swap two values here or if this is bug. Given the following code:

fun main(args: Array<String>) {
    var x0 = 25
    var y0 = 26

    var x1 = 27
    var y1 = 28
    
    x0 = y0.also { y0 = x0 }
    x1 = y1.also { y1 = x1 }

    println("x0=$x0, y0=$y0, x1=$x1, y1=$y1")
}

Kotlin/JVM will produce the following output (x0 <-> y0 and x1 <-> y1):

x0=26, y0=25, x1=28, y1=27

Whereas Kotlin/Native does the following:

x0=25, y0=25, x1=27, y1=27

Any thoughts?

How does one link shared objects when compiling c interop?

hello, I know that right now kotlin native is not supported in multiplatform development, but is there any other non-officially supported way to share the same code in native and jvm for example?

I’m unable to compile a framework using 0.5, through the konan gradle plugin -

error: you have not specified any compilation arguments. No output has been produced.

The provided calculator sample compiles fine - so I suppose this a configuration issue on my end. Any ideas? I’m using a very similar build script setup as the sample is.

Anyone seen an error like this when building K/N application with Gradle?

* What went wrong:

Cannot download Kotlin/Native compiler

> Server returned HTTP response code: 403 for URL: https://download.jetbrains.com/kotlin/native/builds/releases/0.5/linux/kotlin-native-linux-0.5.tar.gz

Is there a way to override the toolchain that clion uses for kotlin/native

although perhaps it deserves its own ticket

Any update from Kotlin/Native plugin in Clion?

One last question: does Kotlin Native support extension methods? I've got this bit of hackery:

fun Byte.xor(v: Byte): Byte = ((this.toInt() and 0xFF) xor (v.toInt() and 0xFF)).toByte()

and I'm seeing

api8610509288099049914.cpp:39:25: error: expected member name or ';' after declaration specifiers
      cpu_x1_KByte (*xor)(cpu_x1_KByte thiz, cpu_x1_KByte v);

Hi all, I wanna try to build the calculator example for ios, but i got the error

Showing Recent Errors Only
Execution failed for task ':calculator:compileKonanKotlinArithmeticParserIphone_sim'.
> Classpath of the tool is empty: konanc
  Probably the 'konan.home' project property contains an incorrect path.
  Please change it to the compiler root directory and rerun the build.

How could I import the path in XCode?

Hi, I wonder if there is a link to a kotlin native road map?

Hi! Are there some standard libraries for http calls for kotlin native ? what about Rx ?

Follow up to ^^^ is the kotlin std lib available for native? Docs here do not mention native, maybe because it is preview. https://kotlinlang.org/api/latest/jvm/stdlib/index.html General question is what is the lowest common standard library for sharing code btw platforms? Is there/will there be a std lib with collections, file I/O, etc?

the feature "multi platform projects"
is experimental and should be enabled explicitly

Can it be enabled, and if so how?

@here can we manipulate the dom like setting innerHtml for wasm32 target ? I saw the canvas example, I am trying to manipulate the dom, any pointers/help would be greatly appreciated.

I have a gradle kotlin-native project; is there an easy way to open it in CLion?

Can I have a Kotlin/Native module for a multiplatform project?

is trying to call an

ioctl

from kotlin-native, specifically

ioctl(STDOUT_FILENO, TIOCGWINSZ, &winsize)

but how does one create a winsize object?

Also, where did you get what looks like javap output from?

Is it possible to output a framework and an android SO from the same kotlin/native module? Im trying to add a library artifact (to be used for android) and a framework for ios, but it always seems to try and generate a framework for my android target. Sample build.gradle here

Can Kotlin/Native be used for JVM bindings?

How do one print to the

stderr

in K/N?

is this is a proper way for NSData to String? val strData = NSString().initWithData(data, NSUTF8StringEncoding)
