Hey there, I'm researching Kotlin Native and I'm wondering if it's possible to build a library instead of an executable. And if so, how do you then make that library callable from another language (for example C)

I've experimented with

-nomain

parameter to

konanc

but it still expects a library to provide

main

function

i just saw that basic windows support landed on master, so i decided to give it a try but gradle fails: https://gist.github.com/Scellow/ff2375281ee077df5a92388c36e002af do i need to do something specific for windowd ? or it is too early to test ?

sample code from https://www.rust-lang.org/en-US/ in Kotlin Native :kotlin: on windows FeelsGood man, kotlin syntax is 10000000000x better

Hopefully you are not going to do it like

println("${when(…) {…}}")

😄

Yeah, this is what I mean in paragraph about Isolationism http://marcinmoskala.com/kotlin/2017/05/31/what-i-hate-in-kotlin.html

we now support generation of Windows binaries (64-bit on 64-bit hosts for now), so if you're interested in testing Windows, feel free to try the current master. Contributions (for example cross-compilation from Linux) are welcome.

so who here is working on a Kotlin (Native) based cross-platform game framework engine? let me know, so I don’t have to.

React with an Apple 🍏 if you demand iOS simulator support for Kotlin Native :kotlin-flag:

Can I use Kotlin-native for run on Arduino? 😃

No

Is there additional information available on the Kotlin Native IDE? Need to know what desktop platforms (eg Linux, Windows, MacOS) the IDE will run on.

Is there a way I could compile kotlin native and then use it in ios project as a dependency? Is there an instruction how to do it?

But running is not enough 🙂 It needs to work with appropriate SDK, integrate with tools (like flashing), etc. I don’t think there is an open standard for everything, so that would take time and probably vendors coordination, or community effort. And this normally take a lot of time…

So, I'm attempting to run the Windows toolchain under Wine, which, aside from the DOS batch scripts having to be rewritten in bash, seems to work. At least for "hello world". But trying to build the bindings for a header file with cinterop, I get this error:

nativelib-build\natives\cstubs.c:2220:21: error: always_inline function '_cvtsh_ss' requires target feature 'sse4.1', but would be inlined into function 'win32_kni__cvtsh_ss' that is compiled without support for 'sse4.1'
    return (float) (_cvtsh_ss((unsigned short)__a));

...meaning that Kotlin/Native on Windows requires SSE 4.1? It's apparently not supported on AMD processors made before 2011, like mine: http://www.cpu-world.com/Glossary/S/SSE4.1.html

will kotlin-native support reflection? where i can read about reflection in kotlin-native?

@olonho Is there anything planned around generating kotlin code for kotlin-native? I know annotation processors work for the jvm, but is anything being worked on for generating kotlin-native code? If not, are there any ways we can do static analysis of Kotlin code at compile time to make our own code generation plugin? I haven't found any resources on static analysis of kotlin code.

@orangy thanks. I mean on hardware without OS, some sort of 'kernel'. I can't find anything like that in his blog

@gimlet Not sure that all commited, but https://github.com/semoro/KOS

Hi, I was wondering why is the constructor for Array inlined in Kotlin native. I looked up the source and it seemed to be using some annotations for "compiler magic". https://github.com/JetBrains/kotlin-native/blob/master/runtime/src/main/kotlin/kotlin/Array.kt

Perhaps because of this https://docs.oracle.com/javase/tutorial/java/generics/restrictions.html#createArrays ?

will the compiler be ported to kotlin native in the future ?

for those, who is interested in coding for Android using Kotlin/Native, take a look at this sample: https://github.com/JetBrains/kotlin-native/tree/master/samples/androidNativeActivity

It looks like the v0.3 release didn't get tagged? Having trouble figuring out which commit the release corresponds to.

Which 3rd party libraries could be used with Kotlin Native? For example, if I want to write app that reads JSON from file and writes it to database, would I use Jackson and Hibernate or some C stuff?

trying to run the kotlin/native samples with the gradle setup and having some issues getting it to sync. Anyone seen this?

Are there any steps that I need to take to set up IntelliJ for Native?

Are there any plans for unsigned primitive types in Kotlin native?

I have the interest of using Kotlin to provide native functions and expose them through node ffi
