Android NDK - no type named 'function' in namespace 'std'

I keep getting the following error in the Android NDK when building with Cocos-2dx and Clang

jni/../../Classes/Facebook/FacebookConstants.h:44:14: error: no type named 'function' in namespace 'std'
typedef std::function<void()> FacebookLoginCallback;

Solution

  • I think You don't have a linker error. You have a compiler error. The problem is, you dont have mention support of C++11 in your application. You have to use the one that comes with Clang by specifying the -std=c++11 compiler flag (APP_CPPFLAGS) in Application.mk file which is in your jni folder. i.e.

    APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -DCOCOS2D_DEBUG=1 -std=c++11
