Android example fails to compile

[KraXarN]

I followed the tutorial on the Github wiki and tried to compile SFML for Android. I got til the make command, but got the error '#include <ostream> No such file or directory'. The tutorial told me to include '-DANDROID_STL=stlport_shared' in that case and after doing that it compiled just fine. However, the example project fails to compile after 'ndk-build' with the following error:

Tried on both Windows (Using minGW) and macOS, but both fail with the same error. Am I missing something?

The current version of SFML with NDK version >12 do not work together when you use libc++ as STL implementation (has the best c++11 support). If stlport is fine for your usecase go with it, if you need libc++ you have two options:

1) Downgrade to NDK version 12
2) Use this pull request . With this pull request you have to use the toolchain provided by your NDK (NDK_ROOT/build/cmake) to build SFML, the rest works the same.

Okay, thanks a lot!
