I am trying to compile some example application on S32 design studio for vision 2.0 with orb feature extractor from apexcv. However, when i compile the function it always returns undefined reference error to all function in ACF_PROCESS. I make sure that the libacf.a is on the library linker list, so i can not really figure out other reason would caused this problem. Can anyone give me some suggestion on this issue?
The system i am compiling the code is Ubuntu 14.04.
