I'm trying to install Octave according to the instructions here:
http://wiki.octave.org/Octave_for_MacOS_X
using Homebrew.
I have the XCode command line tools installed. I checked and I also have HomeBrew installed. I just installed XQuartz.
I try to run brew tap homebrew/science, and I get:
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 26: /usr/local/Library/brew.rb: Undefined error: 0
Do I need to do this in a certain folder?
Not sure why I'm getting this issue.
Thanks for the help,

I'm trying to compile a cmake project on a RasberryPi with Fedora Arm 36 and in cmake I use pkg-config. It is correctly installed but I get this error:
/usr/bin/pkg-config: line 8: /usr/bin/armv7hnl-redhat-linux-gnueabi-pkg-config: No such file or directory
In the /usr/bin directory there is a file called armv7hl-redhat-linux-gnueabi-pkg-config (missing n in armv7hnl) is this a bug?
What can I do?
Edit
I've reinstalled pkg-config but still the same error.
/usr/bin/pkg-config is just a bash script that calls the appropriate executable and so I hard coded the one previously mentioned, I don't get an error but pkg-config can't find gtkmm-4.0 which is installed.
I have tried installing a package in Octave using this command:
pkg install signal-1.4.0.taz.gz
but I received the following error:
error: pkg: failed to read package 'signal-1.4.0.taz.gz': Couldn't resolve host name
error: called from
pkg at line 429 column 17
Does somebody know what that means?
You have mis-spelled the name of the package's tarball. It is likely signal-1.4.0.tar.gz rather than signal-1.4.0.taz.gz (Note that one has TAR and the other has TAZ in the extension)
pkg install signal-1.4.0.tar.gz
Essentially what is happening, is that Octave is unable to find the file signal-1.4.0.taz.gz on the file system (due to the mis-spelling) so then it attempts to download the file from the internet. When it tries to resolve signal-1.4.0.taz.gz as a URL, DNS name resolution fails giving you the error that you're encountering.
I just had the same issue/error when trying to install the econometrics package on a windows install. In my case, for reasons unknown I was getting the following error:
>> pkg install econometrics-1.1.1.tar.gz
error: pkg: failed to read package 'econometrics-1.1.1.tar.gz': Couldn't resolve host name
error: called from
pkg at line 433 column 17
The only way I managed to get it, was by first downloading the package manually into the current working directory of Octave. (See pwd output.) Only then did the install command work.
pkg install econometrics-1.1.1.tar.gz
pkg load econometrics
I recently have this problem, you need to place the file in the Octave directory and from there rigth clik on the file to copy to clipboard and then paste from there.
example:
to me work to change the document to disc D, and then install like:
pkg install symbolic-win-py-bundle-2.9.0.tar.gz
I have tried to install image package but it returned error:
pkg install image-2.4.1.tar.gz
pkg: unable to find the command shell.
error: called from 'shell' in file C:\Octave\Octave-4.0.0\share\octave\4.0.0\m\pkg\private\shell.m near line 42, column 7
How can I solve it?
Octave is trying to execute "sh.exe", but cannot. This exe may come by cygwin or some other tool to allow the execution of Unix style commands.
ok this seems like a really silly question but for some reason I'm having issues installing a package into octave (using Ubuntu 12.04). I used the command:
pkg install signal-1.3.0.tar.gz
and got the error:
warning: file signal-1.3.0.tar.gz does not exist
But the file does exist and I have the tar file in the same folder as octave. I can't work out what the issue is... any ideas?? Thanks in advance!!
I installed latest Octave on Ubuntu 14.04 machine. However, when I tried to run imread command, it showed the following error message:
octave:12> imread('newfile.png')
error: imread: invalid image file: /usr/lib/x86_64-linux-gnu/octave/3.8.1/oct/x86_64-pc-linux-gnu/__magick_read__.oct: failed to load: /usr/lib/x86_64-linux-gnu/octave/3.8.1/oct/x86_64-pc-linux-gnu/__magick_read__.oct: undefined symbol: _ZN6Magick5ColorC1Ehhh
error: called from:

error: /usr/share/octave/3.8.1/m/image/imread.m at line 107, column 30
Can someone please suggest how to solve it?
Thanks!
Following these steps worked for me [Author: Christoffer Cronström (hymyly)]:
Install the dev packages needed to build octave.
sudo apt-get build-dep octave
Get the official source package. Do this in a clean directory, because it will get polluted.
cd ~/some/suitable/directory
apt-get source octave
Build it. This took roughly an hour for me.
cd octave-3.8.2
dpkg-buildpackage
Either run it from the build directory:
./run-octave
...or most preferably install it over the official octave:
cd ..
sudo dpkg --install octave_3.8.2-4_amd64.deb

How did you instal Octave? The error suggests that you're missing GraphicsMagick C++ interface (package libgraphicsmagick++3) but
if you installed Octave from Ubuntu's package manager you should not have had this problem; * if you compiled it yourself, Octave should have disabled imread completely and you'd have a very different error message.
So my guess is that you build it yourself, either with:
your own build of GraphicsMagick++ which are not being loaded anymore, you may need to add their path to the dynamic linker load path (either on /etc/ld.so.conf.d./graphicsmagick or define LD_LIBRARY_PATH);
the libraries from the package manager which you have since accidentally removed (since you did not install Octave from the repositories, your package manager will not know that libgraphicsmagick++ is installed for a reason).
Either way, the solution is easy. Install Octave from Ubuntu's package manager. One of the main reasons package managers exist is to avoid this type of problems, i.e., missing dependencies.
