is there a way to AOT kotlin jvm apps

[ephemient]

yes, GraalVM native-image

[ephemient]

Compose Desktop uses Swing and GraalVM native-image claims to support Swing on Linux: https://www.graalvm.org/release-notes/21_0/#native-image:~:text=Added%20AWT%20and-,Swing,-support
I have not tried it, though. I've only used native-image on CLI binaries

[Koneko Toujou]

as apparently we can use jaotc but i dont know what to give it

[ephemient]

jaotc doesn't exist anymore. use GraalVM native-image. https://openjdk.org/jeps/410

[Koneko Toujou]

i tried passing the classes but i get

> jaotc --compile-for-tiered --verbose --output DESKTOP.AOT --directory desktop\build\classes\kotlin\jvm\main

Compiling DESKTOP.AOT...

Found linker: C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.34.31933\bin\Hostx64\x64\link.exe

how would i do this using GraalVM

imma just run java JIT version for now

Kotlin JVM apps in general can be AOT compiled via GraalVM/native-image but Compose apps cannot. This is due to several limitations.
1. GraalVM/native-image does not support AWT on all platforms.
2. Even if AWT is supported, e.g., by the Bellsoft NIK (which is derived from native-image) this still does not work because of some strange handling of the shared AWT library by JetBrains.
Just have a look at these issues.
