CameraExample does not run on Linux #2

Open juliesymons opened 8 years ago

juliesymons commented 8 years ago

This tutorial example does not execute on Linux. The exception trace is listed below.

CameraExample calls ColorWebCam, cogio.webcam.ColorWebCam from the cct-io repository (cogio). This in turn has dependencies on libraries from bytedeco.

Perhaps the dependencies are not defined or resolved correctly to pull in the correct version of the bytedeco libraries that run on Linux.

Here is the stack traces from Linux. From Linux

The windows version works fine.

I have a similar bytedeco issue on Solaris for BackgroundSubtraction, ColorMovieExample. The exception is a bit different, though:
