C++11 support for Android NDK in Qt Creator

[daljit97]

I have tried to integrate the https://github.com/nlohmann/json library in my Qt project for Android. When I compile I get many errors:

error: 'to_string' is not a member of 'std'
error: 'strtof' is not a member of 'std'

and others. It seems that some C++11 features are missing in the build. I know that in Android Studio projects you can add APP_STL:=c++_static to the Application.mk file and that should solve the issue. But how can I add C++11 support for Android NDK in a project in Qt Creator? I have already added this to my .pro file:

CONFIG += c++11
QMAKE_CXXFLAGS += -std=c++11

That project is CMake based. How are you building the library?

Well since it is a header only library, I just downloaded the header and included it in my project like this:

#include <nlohmann/json.hpp>

Running it on Desktop (Linux) works fine
