Have you googled "fatal error: 'type_traits' file not found" to find solutions ?

Thanks :)
Well, maybe once I gain the needed knowledge :)


Now I tried it on my ArchLinux. Using NDK r19c, SDK 22&26, Qt 5.12.2, PyQt5.12.1.
I'm getting

I'm pretty sure that this is about gcc/clang/c++17, but I'm using the proper versions, I suppose.


Thanks.

You have to use Linux or macOS as the host. Using Windows as a host
shouldn’t require too many changes, so patches welcome...
