Using C++11 features in Oculus Mobile SDK samples

I want to use std::shared_ptr in the Oculus Mobile SDK Sample code. It won't compile. The error message is: 'shared_ptr' is not a member of 'std'.

I'm using:

• Oculus Mobile SDK 0.6.0.1
• Android NDK r9d
• Eclipse 4.2.1

I confirmed that NDK_TOOLCHAIN_VERSION is set to 4.8 in Application.mk (in the root directory ovr_mobile_sdk_0.6.0.1). I tried setting the cpp flags to C++11 values in every Android.mk and Application.mk I can find. I tried using Clang instead of GCC. I made sure the relevant include paths are added and tried adding others. I even tried the latest NDK r10e.

Unfortunately, none of this works. How can I use std::shared_ptr in the Oculus Mobile SDK sample code?
