Re: image-acquisition package installation

Hi Nkosi,
please use bottom or interleaved posting style on this mailinglist.

You previously wrote: "After re-installing the dependencies a number of

another error has come up"

Is it possible that you have a botched Ubuntu installation?
Can you please try to install the package in a fresh Ubuntu (use the
mentioned version) with Octave 4.2.2?

This is very strange. What version of g++ are you using?
