error: cannot find -lc++ qt 5.12 android
-
For me fixed reinstalling (updating) next packages -> android-aarch64-qt5 and android-armv7a-eabi-qt5 with editing their PKGBUILDs and disabling packages for build tools and platform tools.

I have the same problem and I don't know how to resolve it. I had already done all your issues and don't works...
-
I had the same issue with NDK 20. What worked for me was to download NDK r19c (here : https://developer.android.com/ndk/downloads/older_releases) and configure QtCreator to use it in Tools/Options/Devices.
@Woazim thanks, i used your advise and it worked.

The error: cannot find -lc++ using ndk r20 can be solved like this:
https://codereview.qt-project.org/c/qt/qtbase/+/264903/9/mkspecs/android-clang/qmake.conf#34For example to compile for android armv7 ndk r20, locate the file:
C:\Qt\5.13.0\android_armv7\mkspecs\android-clang\qmake.conf
and add the missing-nostdlib++
for android x86 (i use this for emulator), locate the file:
C:\Qt\5.13.0\android_x86\mkspecs\android-clang\qmake.conf -

@Albertino @AriosJentu Hello , I am getting while deploying 5.10 project into QT 5.13. It is perfectly deploying for windows but for android unable to deploy i have already tried all available solutions but nothing is working out for me.
This is my error-

You also can write this into your own qmake file, not into system one. To be precise, just add into your project's .pro the following:
QMAKE_LINK += -nostdlib++and that's it

@rickf I'd like to know the same thing. Is this just a workaround or the correct setup?

FYI If this is https://bugreports.qt.io/browse/QTBUG-70631, it's claimed to be fixed with 5.12.5 and 5.13.0
