[RuiCuco]

I do on a new project:

lime build android

and after a while I receive these errors:

What should I do to compile correctly for Android and thereby generate an APK?

[joshtynjala]

This is an hxcpp bug. It’s been fixed, but not released to Haxelib yet.

HaxeFoundation/hxcpp#1041

You can either install hxcpp from GitHub, or you can roll back to Haxe 4.2 and hxcpp 4.2.

Posting a similar error related to hxcpp and Android for anyone who might get here from Google:

This seems to be related to how hxcpp compiles its mbedtls dependency. It is fixed in the following hxcpp PR (which is not merged yet, at the time I am writing this).
