Does the GlobalScope.launch function not work with the linuxX64 target? Confusing error messages keep on appearing, eg:

kotlin.IllegalStateException: There is no event loop. Use runBlocking { ... } to start one.

I want to run IO bound tasks (network orientated) that run on a separate thread. The main thread with the linuxX64 target is mainly used for tasks that need to block (eg printing messages to the console). Linux unlike JS (the JavaScript platform) for example allows for multiple threads to run at once.

I think you need to make a dispatcher.

Are you using native-mt?

[napperley]

What do you mean by native-mt?

[napperley]

Ended up using runblocking as mentioned in the error message which is working as expected.
