OpenCV-android 2.4.7.1 linker error: undefined reference to 'typeinfo'

Building an ndk-based project for android and I get a bunch of linker errors such as

OpenCV-2.4.7.1-android-sdk/sdk/native/libs/armeabi-v7a/libopencv_flann.a(miniflann.cpp.o):miniflann.cpp:function cvflann::anyimpl::typed_base_any_policy<double>::type(): error: undefined reference to 'typeinfo for double'

All the errors are of the same type and within flann. I'm using ndk r9b with gcc-4.8. Also, I don't have this problem with 2.4.7. What changed in 2.4.7.1 that might cause this?

OpenCV4Android SDK 2.4.7.1 was build with GCC 4.6 and GNU STL static, try to change the compiler or/and STL type.

I am also using GNU STL static.

Unfortunately, I'm using c++11x features so can't go back to gcc 4.6. Which version gcc was 2.4.7 built with?

It was the same compiler and same NDK. I recommend you to create small issue reproducer and file a bug on code.opencv.org
