在 Mac OS X 上的 Octave 上安装图像 pgk

Question

I installed GNU Octave, version 4.2.0-rc2 on my Mac[0] using Homebrew[1].

But now I tried to install the image pkg[2].

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
checking for octave... /usr/local/Cellar/octave/4.2.0-rc2/bin/octave-4.2.0-rc2
checking for mkoctfile... /usr/local/Cellar/octave/4.2.0-rc2/bin/mkoctfile-4.2.0-rc2

checking whether clang++ -std=gnu++11 accepts -g... yes
checking for clang++ -std=gnu++11 option to enable C++11 features... unsupported

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

Konfiguriert mit: ../gcc-6.2.0/configure --enable-languages=c++,fortran --with-gmp=/usr/local

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.
