​This error seems to suggest that your installation of octave-image is corrupted. It looks to me that you either do not have libGraphicsMagick++

installed, or your octave-image was compiled against different and incompatible version of one.

Do

ldd /usr/lib/x84-64-linux-gnu/octave/3.8.2/oct/x86_64-pc-linux-gnu/__magick_read__.oct

(from the shell prompt)

and see if you have all dependencies resolved.

Dmitri.

Hello,

I would like to apologize to the Octave GNU team for posting incorrectly and also not emailing help list. I am new to such lists, I use gmail, and I just replied to the latest email. This time, I scrolled down and posted at bottom.

I am still having the same difficulties even after I removed Octave GNU and reinstalled from https://launchpad.net/~octave. I have sent "Mike Miller" an e-mail as well because I would like to resolve this issue.

Here is my latest diary, and I hope it also cleans up my post a bit because the diary reflects the same error that I was having with the old install which was the original topic of this thread.
