I was getting a weird runtime error about native library something in Eclipse while messing around with OpenCV (using Processing.org).
!!! library OpenCV not found
Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: capture

I found the answer was to configure native libraries in my project. This is something I’ve never done in Eclipse so I thought I’d post it in case someone googles this error message. First, I set up my project like the following. Notice that I created a folder named “native”. I moved the shared library files (.dll, .so, .jndilib) into this folder. I am on a mac but I moved the DLL files anyway.

Then I went into my project properties and set the Native Library Location as this folder. Viola. The processing applet launches.
