I have OSX 10.10.5 with Octave 3.4.0 running (installed, who knows how, I did it a million different ways through port, file extraction, ftp, homebrew…). I tried to update my Programme (brew install octave or sudo port install octave) and Terminal spits out:
Warning: octave-3.8.2 already installed, it's just not linked
Okay, great. So I have a better programme somewhere installed. What now? How on earth am I supposed to “just link” the newer installation?
If you install octave with Homebrew and it doesn't link it it should tell you why. You can force Homebrew to link octave with
$ brew link --overwrite octave
You can also add the --dry-run option to check and see what Homebrew will do to link octave
$ brew link --overwrite --dry-run octave
A possible reason for Homebrew not linking octave is that you've installed it by another method, MacPorts for instance. It is not recommended that you use both Homebrew and MacPorts on the same system.

I'm trying to remove duplicate opencv versions on my mac. It seems that I have installed using both homebrew and mac port, so I decided to uninstall mac port completely, following this guide
But when I uninstalled mac-port and softwares installed with port, I couldn't use softwares installed by brew anymore
$ brew install pkg-config
$ pkg-config
-bash: /opt/local/bin/pkg-config: No such file or directory
I guess it's because the system still believes that pkg-config is in mac-port location. But how to fix it? I haven't find solutions with google.
Thanks in advance!
problem solved by editing PATH setting in ~/.bash_profile (or bashrc).
I have been able to install Caffe but I had a lot of issues and that's because I didn't follow the instructions very well.
I have a Mac OSx and I'm reading the OSx guide for installation.
In this point:
when I type hdf5 opencv I get:
"hdf5: command not found"
I've tried to install hdf5 by Homebrew and MacPorts but I'm still getting:
"hdf5: command not found"
Does anyone have any clue?
Thank you very much.
according to the answer of #mattias, my binaries in /usr/local/hdf5 are:
hdf5 is not a command or anything else. The documentation is just bad, it has to be:
brew tap homebrew/science hdf5 opencv
So, what I mean is, we have to install hdf5 and then link it to Caffe. But executing hdf5 is not what the guide meant.
You can install hdf5 from source. I just tested on OS X 10.9.5.
wget http://www.hdfgroup.org/ftp/HDF5/current/src/hdf5-1.8.14.tar
Unpack,
tar zxfv hdf5-1.8.14.tar
Enter directory
cd hdf5-1.8.14
And then,
./configure --prefix=/usr/local/hdf5 # or where you want it
make
sudo make install
Then you have it installed in /usr/local/hdf5.
Good luck!
I am trying to install ROOT (cern.root.ch). When I run ./configure , I get a message that libX11 is missing and must be installed.
I did some research and found that I need to install
) XQuartz (I already have the latest version.)
) Command line tools in Xcode.
I tried installing Command Line Tools from apple's developer website. The installation goes through smoothly but how do I know whether it has been installed? I still get libX11 missing error with root's configure command.
I also tried xcode-select --install and it once went through smoothly and then later again gives error saying this package is no longer maintained - or something of that sort.
I understand I may have multiple installations... But I am still facing the problem of not having libX11 and not being able to install ROOT.
Thanks,
Hershal.
This link and the one referenced in it suggests you use homebrew (brew) to install it
$ ruby <(curl -fsS https://raw.github.com/mxcl/homebrew/go)
$ brew doctor
Remember to add the Homebrew directory to your PATH by adding the directory (found with brew --prefix) to your .bashrc, .zshrc or whatever shell file you’re using (.bashrc is the OS X default). We’ll also add the XQuartz binaries to the PATH in case anything needs them in the future.
export PATH=/usr/local/bin:/opt/X11/bin:$PATH
Start a new Terminal session to pick up the changes.
Now that Homebrew is installed, we can use it to install the required dependencies. Each may take some time as Homebrew generally compiles from source.
$ brew install gfortran # Fortran compiler
$ brew install python # Python interpreter
$ brew install pcre # Regular Expressions library
$ brew install fftw # Fast Fourier Transforms
$ brew install cmake # Cross-platform make
install root
$ brew tap homebrew/science
$ brew install --with-cocoa root
You don't say whether you have installed XCode as well as the commandline tools but I think you will need it
When running R CMD check on packages on a Mac build server, I'm getting a warning
‘qpdf’ is needed for checks on size reduction of PDFs
I can't seem to get qpdf installed and on the system. I tried installing via the fink package manager, but according to the package database (http://pdb.finkproject.org/pdb/package.php/qpdf), qpdf doesn't seem to have been built since osx 10.6, and I'm on 10.8.3.
Can anyone point me to qpdf mac install or build instructions? Or is there a way to disable the warning when checking R packages?
This is somewhat related to the question qpdf.exe for compactPDF?, although they were on a windows machine and I'm on a mac.
You can install qpdf with homebrew:
brew install qpdf
MacPorts can help you. Download MacPorts from http://www.macports.org/ and run sudo port install qpdf.
After I got MacPorts installed and did a 'sudo port -v selfupdate', I try to install meld.
The installation just starts to Fetching all kinds of stuff
gnome-comoon
perl5.8
perl5
pkgconfig
.....
this goes on and on.
Is that normal?
You may want to install it via HomeBrew (already mentioned before):
brew install homebrew/gui/meld
Though you may face stability issues (as I did). So I'd rather recommend to use "Meld for OSX":
Go to https://yousseb.github.io/meld/
Download DMG file you prefer (e.g. "Download latest DMG" https://github.com/yousseb/meld/releases/download/osx-6/meldmerge.dmg)
Install it to your Applications folder
We are basically done, but it is not accessible via command line.
Solution:
Write a small wrapper to run from Terminal:
echo -e '#!/bin/sh
params="$#"
open -W -a Meld --args $params' | sudo tee /usr/local/bin/meld
sudo chmod +x /usr/local/bin/meld
Try (you must use absolute paths though):
meld /home/a.txt /home/b.txt
Or just run Meld from menu.
meld is now available in homebrew. The formula can be found here.
See this answer by cmedeiros on SuperUser for more information on installing and getting it to work. This is much easier than using MacPorts.
Current command with updated formula to install meld with homebrew is:
brew install caskroom/cask/meld
Yes, it is normal to pull in dependencies but it shouldn't take too long. For comparison, installing Meld with Homebrew took about 15 minutes for me.
For reference, my installation of Meld on OS X Mavericks:
Install Xcode from the app store
Install XQuartz from package (Meld will complain if you don't have it)
command line: 'brew install meld'
If you are prompted to install the Xcode command line tools at some point, do so.
Hope this helps.
Unfortunately, the is very normal with MacPorts, and is the reason that people many have switched to homebrew http://github.com/mxcl/homebrew
However, I found this post because homebrew doesn't include Meld. Sigh.
Consider downloading macOS meld version dmg https://github.com/yousseb/meld/releases/
Brew now works brew install --cask meld.
See https://formulae.brew.sh/cask/meld#default
UPDATE Jul-23-2020
Just do :
brew install homebrew/gui/meld
using the updated brew link: brew install caskroom/cask/meld
even after this its not working when I install backup and restore tool by google. I guess its messing up with the python version.
