To grab an image from a camera in Halcon, you have to open Framegrabber. (open\_framegrabber). However, in Windows this works fine, but running Halcon (Hdevelop) in Linux creates an error:

Dynamic library could not be opened, error nr. 8600. Does anybody know the solution?

What is the exact code you are trying to run?

Edit: it looks like you are trying to use DirectShow (= for Windows).  
Try useing ‘Video4Linux2’ as framegrabber.
