# kotlin-native

[Mikołaj Karwowski]

Is it possible to run kotlinc-native compiler on Raspberry Pi?
As I understand the prebuilt kotlinc release packages are only meant for limited targets
And since RPi is AARCH64, none of them match

So I built the kotlinc-native from source code using :bundle :distPlatformLibs
But still I cannot use it on RPi, the error I'm getting is:

../coding_tools/kn_d1/bin/kotlinc-native helloWorld.kt -o hellod1
error: compilation failed: /home/pi/coding_tools/kn_d1/konan/nativelib/12300764954060379176/libcallbacks.so: /home/pi/coding_tools/kn_d1/konan/nativelib/12300764954060379176/libcallbacks.so: cannot open shared object file: No such file or directory (Possible cause: can't load AMD 64 .so on a AARCH64 platform)

I don't understand where that nativelib/12300764954060379176/libcallbacks.so directory in middle come. I dont - in fact - have it there

pi@raspberrypi:~/coding_tools/kn_d1/konan/nativelib $ ls
libcallbacks.so   libllvmstubs.so                               liborgjetbrainskotlinbackendkonanfilesstubs.so
libclangstubs.so  liborgjetbrainskotlinbackendkonanenvstubs.so

Also - pardon me, but I'm novice when it comes to compilers, buildtools, cpu architectures etc
So any guidance here would be highly appreciated

I'm 99% sure that you cannot and Jetbrains don't support the Pi as a build host. I've always had to cross compile to aarch64 from my windows x86 machine.
Of course, Jetbrains do support a MacOS native build on the same underlying cpu architecture...

Thank you both
That KT-36871 ticket was super useful
Seems it's beyond my skills for now, but that's some decent direction already
