I installed GNU Octave, version 4.2.0-rc2 on my MacBook Pro (13-inch, Mid 2012, macOS Sierra) using Homebrew.
But now I tried to install the image pkg.
I tried downloading it and then using this line:
"pkg install image-2.6.0.tar.gz"
Then I tried installing it with this line of code:
"pkg install -forge image"
Both resulted in the following output:
configure: error: *** A compiler with support for C++11 is required

pkg: error running the configure script for image.

But I think I installed GCC correctly:
gcc -v
Has the following output:
Es werden eingebaute Spezifikationen verwendet.

What is my mistake? Or what have I done wrong?
I had the exact same problem. Just download the older version 2.4.1 of image
and installation should work as expected.
