Illegal instruction

[simon1tan]

I am getting "Illegal instruction" when I try to run the programs after successful compilation. Have opencv 3.2.0 installed. Below is the output of cmake. Am I missing something, wrong versions?

This is a compiler issue. Try a different compiler (Clang) or older version of GCC. I would suggest compiling with OpenCV 3.1.0 and see if you the error is still appearing.

From Open CV version 3.0 Akaze is integrated in the library itself.So if u r trying to integrate it from outside, it may show some errors. However the open cv can be configured without it. U can try 2.4.9 as well.
