[SOLVED] Installing image pgk on Octave on Mac OS X

Installing image pgk on Octave on Mac OS X

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
checking for a sed that does not truncate output... /usr/local/bin/gsed

pkg: error running the configure script for image.
error: called from
    install at line 200 column 5
    pkg at line 392 column 9

But I think I installed GCC correctly:

gcc -v

Has the following output:

Es werden eingebaute Spezifikationen verwendet.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-apple-darwin15.6.0/6.2.0/lto-wrapper

What is my mistake? Or what have I done wrong?
