[PyQt] PyQtDeploy: Supported development hosts for Android

[Zhao Lee]

You could also search with the keyword Qt, that is to google  "Qt fatal error: 'type_traits' file not found", I found some threads said it was NDK that caused the problem, but I am not sure if it is true,  maybe you could give it a try! 
No matter whether you solved the problem in the end, drop me a line, I am really interested in whether it is viable to develop Android APP with PyQt.

Most of comments are about building with c++11. I added a config setting in .pro files but it didn't work. I think it's thinking its gcc while its clang, somehow.


I'll keep looking and hopefully I get something working.


Thank!

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...
