One of my tests is failing on myproject:iosX64Test iosX64 target but is passing on myproject:iosSimulatorArm64Test . How could I find the reason for this happening? Does anything to do with the fact I am using an Arm64 chip (Apple M1)?

[russhwolf]

I'm surprised that iosX64Test is even running if you're on an M1 machine.

[David Nedrow]

How are you running the tests? From a terminal, or an IDE?

[Jose Garcia]

I am running them using ./gradlew check
When I run them through the IDE I can't see the option to run them on iosX64 as Russell expects

[David Nedrow]

OK, try arch -arch x86_64 ./gradlew check to see if that makes a difference.

[David Nedrow]

Actually, why are you trying to get them to run as x86?

[David Nedrow]

Do you have some libraries that are x86 only?

[Jose Garcia]

Doing that now, this is my config targets

[David Nedrow]

That looks suspiciously like KMM.

[Jose Garcia]

We are using KMM yes. We are building a multiplatform SDK

[Jose Garcia]

For mobile

[David Nedrow]

?

[David Nedrow]

We’re doing the same.

[David Nedrow]

For mobile.

[Jose Garcia]

"Actually, why are you trying to get them to run as x86?"
This is a question I don't have the answer too. My head is spinning with all those different targets to be honest

[David Nedrow]

Are you using WebStorm?

[Jose Garcia]

No

[David Nedrow]

The only reason you would need to run them via x86 is if they were going to be run on an x86 simulator. On an M1, you shouldn’t have to worry about that.

[David Nedrow]

Oh, you could try setting Xcode to use Rosetta.

[David Nedrow]

Even though you’re running this outside of Xcode.

[Jose Garcia]

The command you shared didn't make any difference. I am trying this one now out of desparation, not that I understand what I am doing
arch -arch arm64 ./gradlew check

[Jose Garcia]

"Oh, you could try setting Xcode to use Rosetta." Ok, I can see where I get with this

[Jose Garcia]

It failed too (as you'd probably expect hehe)

[Jose Garcia]

Is the KMM plugin supposed to know what chip architecture (I presume through how arch is set in my console/bash) I am using and then run either iosx86Test or iosArm64Test depending on such a chip?

[David Nedrow]

Which IDE?

[Jose Garcia]

Android Studio Bumblebee

[David Nedrow]

Same here. Can you post the test?

[Jose Garcia]

I will try to create a little sample project tomorrow and I can share that with you, if you are ok with that?

[Konstantin Tskhovrebov]

could you show full build config? i suppose you haven’t set iosSimulatorArm64 target right. you should declare source sets hierarchy too
