Problem with integration

[LosDanieloss]

Hi,

I'm tring to integrate openalpr with my project. I've decide to go with jni option because I want to use recognize method with byte array as parameter to by faster but I've got problems while integration.
I have change path toOpenCV.mk to my local and do same with paths to LOCAL_C_INCLUDES in Android.mk
After fixing few error like missing namespace alpr or problem with vector passed where should be passed vector I have and up with undefined reference to e.g alpr->recognize, alpr->toJson or even constructor during invoking ndk-build from command line.

Can you help me with this or point the direction to look for solution?

As far as I try googleing I was able to figure out that it is problem with missing *.cpp file in this case looks like missing alpr.cpp but it should be inside of libopenalpr-static.a. Any way I have try to copy alpr.cpp from openalpr project into my jni folder but then there is error with double definition of some define.
