NDK build opencv error

Question

I encountered an error using the NDK way to compile the source code, I will opencv source code copied to the jni directory, prepared Android.mk and Application.mk as well as the source file. Mk file, compiled the following error, please also Give some advice, thanks! ! !

Operating System: Ubuntu 17210 64bit opencv version: 3.3 android-ndk version: 14b
