New kid on the block. Using Ubuntu 16.04 OS (32 bits) with Eclipse IDE ( 32 bits) and cannot link to OpenCV. Perhaps I mistakenly downloaded -version 3. something. So how do I determine current WORKING OpenCV for Unbuntu 16.04 - 32 bits? In long pass OpenCV versioning was always a challenge, still is for me and 3. something is probably wrong one . Like to hear some success stories using same setup as me, it would be encouraging. Cheers
