Hi All,

As I was about to integrate library that I had built with the existing opencv library, I come across some hurdles.

I have changed the opencv source to look for library I have built dependending on the environment variable. Now when I compile, I have errors shown below. As the makefile is CMAKE base, how can I to point to my library?

No idea on your cmake question, but I do have some questions on how to reproduce your work:

I followed http://code.google.com/p/opencv-dsp-acceleration/wiki/Instruction_For_Building_Examples and create a recipe:

Hi Koen,

Thanks for the correction. I have added those instructions. Also, did some modification to the library. Actually the library is the ARM side library and should not be dependent on IMGLib and DSPLib. I am still looking into what can be the issue as ARM side library does not depend on IMGLib and DSPLib.

Ok, I think the issue is with OpenCV. My library build also depends on OpenCV. So, I think the DEPENDS need to add that too.
