    The android CI task fails because the embedded libc++ in the NDK is too old.

    Can it be bumped?

    The android CI task fails because the embedded libc++ in the NDK is too old.

    Can it be bumped?

    Qt 6 docs claim that it supports Clang 14.0.6 (NDK r25b).

    It is possible to build depends with Clang 14.0.7 (NDK r25c) with API level >= 33.

    However, the compiler errors remain the same, unfortunately.

    Clang 14.0.6 (NDK r25b).

    Sure, but the issue is the libc++, not clang. A older libc++ is included in r25, see https://github.com/android/ndk/issues/1530#issuecomment-1659055600

    Right. I mean, ~even the latest Qt~ the Qt 5.15 codebase cannot be compiled with NDK > 25.

    For reference, I guess this was fixed in qt 6.7 then?
