help with android compilation

[Aleksander Kamenik]

Hi!

I have been playing around with GCompris on Linux and now want to
build the Android version as well for use on a tablet.

However I've been stuck with clang not finding libstdc++ (or at least
that's what I guess is the problem). The error is this:

/opt/android/ndk/18.1.5063045/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++

I'm on Ubuntu 21.10 and just can't figure out what package I'm
missing. Here's what's installed atm (many of these are obviously not
needed):

# dpkg --list | grep ++

Can anybody give a hint on what is missing?

Thanks!
