On my project I'm depending on the artifacts produced by another Kotlin Multiplatform library - it also produces native artifacts etc (in this case the ones for iOS):

val commonMain by getting {
    dependencies {
       //....
       api("dependency-group:dependency:version")
    }
}

When I'm trying to run the linkDebugTestIosX64 gradle task I'm getting this error:

e: Compilation failed: Cyclic dependency in library graph for: /Users/boni/Documents/Programmieren/Kotlin/StihlBusiness/StihlBusiness/build/classes/kotlin/iosX64/main/Library

 * Source files: StoreTest2.kt
 * Compiler version info: Konan: 1.3.1 / Kotlin: 1.3.40
 * Output kind: PROGRAM

Is there a way to debug this to get better information?

Maybe add --debug or --info to your command line?

The most direct way is to check out the manifest file in your Library.klib. .klib-files are just zips. Look for depends= in manifest.
It seems like you've got a library dependent on a library with the same name. So if your library is called foo and it has depends=foo in manifest then you get that message. The cycle can be longer, though, spanning several libraries.

Make sure you’re using the same Kotlin version as the library. There’s no compatibility guarantees in Kotlin/Native yet

@alexander.gorshenev thanks a bunch for this tip, it got me to the right path!
In the end the culprit has been the -module-name extraopts (it was visible in the depends line in the manifest). It was the same prefix that I added to the dependency - once I used another prefix it worked just fine!

@Jonas Bark I'm running into same prob. The manifest of my dep has "depends=stdlib lib". lib is the module name from the artifact that is published on maven. What was your solution?

[Jonas Bark]

@Patrick Jackson I wrote my solution just above your answer

[Patrick Jackson]

the unique name is also "lib"...

[Patrick Jackson]

literally changing the gradle module name?

[Jonas Bark]

I just had to change the extraopts -module-name parameter:
compilations["main"].extraOpts.addAll(listOf("-module-name", "SC"))
SC was already used by a dependency, so I changed it to something else

[Patrick Jackson]

in the dependency, or the project?

[Jonas Bark]

both will work 😉 just don't use the same one

[Patrick Jackson]

is this in the targets block?

`
kotlin {
    targets {
        fromPreset(iOSTarget, 'ios') {
             compilations["main"].extraOpts.addAll(["-module-name", "MyName"])
        }
    }
`

[Jonas Bark]

I guess that should work as well

[Patrick Jackson]

where did you put it? sorry to keep pestering. this is a bit unclear as to what is happening and why.

you can also search for "extraOpts" here in this slack workspace

works, thanks so much. is there a issue filed for this? this will be a common problem
