I'm working with android NDK and OpenCV (Version 2.4.1). What I'm trying to do is to profile an android application that uses opencv as a library (and profile the function called into opencv too).
I set up all the environment (android NDK, SDK, openCV, and openCV for android) but obviously is not possible to profile opencv because with android it uses a bunch of prebuilt libraries.
I have tried this two way:
1 - recompile the openCV library adding the C flag -pg
I have tried to put the option -pg but it gives me an error of incompatibility so as is suggested Here. I correct this error putting the option -DENABLE_PROFILING=ON -DOPENCV_LINKER_LIBS=/full/path/to/libandprof.a but however I get this error:

2 - try to integrate some of the source code of openCV in mine c++ android application (extern C)
This is not a good solution because however i can't get a real tree with all the calls of the program, since you don't integrate all opencv source into my app in jni folder.
Can someone give me an hand to solve this issue??
Thank you
