I am working on a Compose Multiplatform application running on Linux (x86_64). I have a class DesktopNativeClient that loads a native library as follows:
class DesktopNativeClient {
private companion object {
private val logger = Logger.withTag("NativeClient")
private const val NATIVE_LIBRARY_PATH = "/path/to/lib.so"
init {
logger.d { "Loading native library" }
System.load(NATIVE_LIBRARY_PATH)
logger.d { "Loaded native library" }
}
}
}
When I load the native library in the main function, everything works fine:
fun main() = application {
DesktopNativeClient()
Window(
onCloseRequest = ::exitApplication,
title = "Title",
state = rememberWindowState(
width = ...,
height = ...
),
) {
MainApp()
}
}
However, when I try to load the native library inside a ViewModel that is provided via Koin, I consistently get a JVM crash at the moment the native library is loaded:
class AppViewModel {
private val nativeClient = DesktopNativeClient()
...
}
ViewModel is created like this:
actual val platformAppModule = module {
factory<BaseAppViewModel> {
AppViewModel(
defaultDispatcher = get(named(DispatchersNames.DEFAULT)),
ioDispatcher = get(named(DispatchersNames.IO)),
mainDispatcher = get(named(DispatchersNames.MAIN)),
)
}
}
And injected:
// in commonMain:
@Composable
expect inline fun <reified T : BaseAppViewModel> AppScreen(viewModel: T = koinNavViewModel())
// in desktopMain:
@Composable
actual inline fun <T : BaseAppViewModel> AppScreen(viewModel: T) {
...

What could be causing the JVM to crash when loading the native library in the ViewModel?
Are there any specific considerations when loading native libraries in a Composable context or when using Koin?
The crash only happens when the native library is loaded in the ViewModel (which is injected via Koin).
The application runs fine when the library is loaded in the main function.
I'm using zulu-17.52
Any guidance on how to resolve this issue would be greatly appreciated!
So, I haven't found the exact cause of it, but it happens only when loading native library while creating an object with Koin.
The simplest solution is to load libraries outside of it.
