I wonder if you're trying to mix code from different architectures (e.g. i386/arm64)

[Sam]

The bit you need to Google for is probably the "'sys/cdefs.h' file not found" part

[Sam]

If you include your OS in your search query I think you'll find suggestions from others with similar issues

[Đỗ Thành Đạt]

But, if i open xcode, i see it.
I dont know why KMM give this log.

[Đỗ Thành Đạt]

I mean, with if xcode i can see the lib. But when i run build, it failed and log libs not found.

[phteven]

Maybe xcode16 is not fully supported?
Saw it on the roadmap today:
Support Xcode 16 in Kotlin

[Đỗ Thành Đạt]

Thanks @phteven

[Đỗ Thành Đạt]

Thank you all, I have solved the problem.

[Alper Tekin]

hey @Đỗ Thành Đạt how did you solve it? 😅

[Giorgi]

yes, how? I have exactly same error

[Giorgi]

okay I figured it out. Kotlin version should be minimum 2.0.21
