Enable C++11 support on Android
android, c++, c++11
Solution
First of all, you will need to ensure that your toolchain is "Cross GCC". Whilst it was the default on my Linux, it was not on my MacOSX Lion.
In order to do this, go to Project Properties > C/C++ Build > Tool Chain Editor. "Current toolchain" should be set to "Cross GCC". You might need to uncheck the box "Display compatible toolchains only".
Then, add an option to LOCAL_CFLAGS in Android.mk:
LOCAL_CFLAGS := -std=gnu++11
We now need to inform Eclipse about where to find the corresponding new symbols (e.g. "std::unordered_map"). Go to Right Click on "jni" > Properties > C/C++ General -> Paths and Symbols -> Symbols -> GNU C++, and add the following symbol (by clicking "Add..."):
Name: __GXX_EXPERIMENTAL_CXX0X__
Value:
(i.e. let "Value" empty)
