Unable to update git from homebrew
I have had problems on one machine to upgrade Git from Homebrew. Let me first tell you how to fix the problem and then what homebrew is about.
The problem
The problem appeared when I tried to upgrade git
brew upgrade git
It turned out to be much more complicated than I anticipated to find the problem. The exact error message was:
Error: Failed executing: make prefix=/usr/local/Cellar/git/1.7.11.3 CC=/usr/bin/clang CFLAGS=-Os\ -w\ -pipe\ -march=native\ -Qunused-arguments\ -mmacosx-version-min=10.7 LDFLAGS=-L/usr/local/lib install (git.rb:49)

It turned out that libiconv was the culprit. Simply uninstall it:
brew remove libiconv
brew prune
brew cleanup
Then run brew upgrade git again and things should work now.
I found the inspiration here.
What is homebrew anyways
Homebrew is a very easy to use and maintain package manager for Mac OS X environments. Anytime you want to install one of those unix-y tools, Homebrew is your friend.
Passed the initial installation, Homebrew is as simple to use as
brew install *something*
and you are good to go. Keeping versions up-to-date are very easy too
# update brew itself
brew update
# update tools installed with brew
brew upgrade
For example here are a few things I have installed and maintain with Homebrew (aka brew for the friends).
- git
- keychain
- mvim
- mongodb
- postgresql
- rsync
- unison
- wget
That also includes some Java tools:
- gradle
- maven
- jboss-as
- ceylon
Homebrew does not install as a privileged user - it is actually discouraged. That makes it a bit picky when permissions are not right.
I have been using this trick quite regularly with success.
