To install meld on Mac OSX I try to run:
brew install meld
but I got the following error:
Error: No available formula for meld
What is the right way to install meld?
When this question was asked, it was not possible using Homebrew. They didn't support it yet.
There are alternative solutions to installing
meld on OS X:
Use a different package manager, like Fink, which is mentioned in meld's installation manual, or MacPorts, mentioned in the issue in Homebrew's issue tracker.
You can probably also compile from source, but need to get the dependencies yourself. Installing one of the other package managers might be easier than that.
You can now install Meld with Homebrew! On macOS, run:
$ brew cask install meld
I've changed the syntax of this answer over time to be more fluent. The following commands are equivalent and also work for at least macOS Sierra and High Sierra:
$ brew cask install caskroom/cask/meld $ brew install caskroom/cask/meld
You should not run the older
$ brew install homebrew/gui/meld because it's deprecated by Homebrew.
As pointed out by @meduz in the comment above, meld now compiles file in brew (haven't tested yet), please try it first, since my original answer is much older.
Today is already possible install it using Homebrew:
brew install meld
I got a issue with pygtk, when I execute meld it says:
Couldn't bind the translation domain. Some translations won't work. Cannot import: pygtk No module named pygtk
I already have pygtk installed from lion, and needed to export it to work:
Add the above line to your ~/.profile to set PYTHONPATH automatically when you open a terminal window.
On OSX El Captain you have just to run:
$ brew install homebrew/gui/meld
I believe that the current correct brew commands are
brew install Caskroom/cask/xquartz brew install homebrew/x11/meld
However after running those commands I ended with the following, which I know that I have overcome on other installations on different macs in the past.
Couldn't bind the translation domain. Some translations won't work. 'module' object has no attribute 'bindtextdomain' /usr/local/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display warnings.warn(str(e), _gtk.Warning) /usr/local/Cellar/meld/1.8.6/libexec/bin/meld:155: GtkWarning: gtk_icon_theme_get_for_screen: assertion 'GDK_IS_SCREEN (screen)' failed gtk.icon_theme_get_default().append_search_path(meld.paths.icon_dir()) Traceback (most recent call last): File "/usr/local/Cellar/meld/1.8.6/libexec/bin/meld", line 155, in <module> gtk.icon_theme_get_default().append_search_path(meld.paths.icon_dir()) AttributeError: 'NoneType' object has no attribute 'append_search_path'
But this time I decided it wasn't worth my time since I couldn't remember the exact remedy.
Instead I found a simple DMG installer and script from Alex Kras to launch the Meld application installed by the DMG installer. The instructions are on his site. Note, though, that this DMG-installed version doesn't respond well to to the
git mergetool input
brew install homebrew/x11/meld
brew tap homebrew/x11 brew install meld
Meld is in Homebrew's X11 repository. Running
brew tap homebrew/x11 allows Homebrew to see Meld in that repository. (2015 answer)
As the formula for Homebrew disappeared i want to mention an alternative. There's this build as OS X application which is simple to install. It was last built in December '14 and requires some tweaks if you want to use it from the command line. I have not yet tried to figure out how.
Don't install it using Brew. Do it this way instead. https://yousseb.github.io/meld/

It's been moved to Caskroom/cask, so run:
brew install Caskroom/cask/meld
