This is a ‘note to self’ about Git and how to build and install on Mac OS X and how to install on Windows.

Building and Installing Git on Mac OS X (specifically 10.5 Leopard)

I haven’t been won over by Fink or MacPorts. There is the git-osx-installer project on Google Code which provides a DMG. But I’m comfortable with Makefiles and I have the Developer tools installed, so I build and install from the source.

Here are the steps I follow:

1. Get the ‘latest stable GIT release’ from http://git.or.cz/. As of this post the latest stable Git release was v1.6.1. Get the tar.bz2¹ file, for example: git-1.6.1.tar.bz2.
2. Unpack the tar file. I have a ~/Projects directory. In the Finder I typically move the tar file to ~/Projects and then double-click the tar. The Mac OS X 10.5 Archive Utility will handle the file. git-1.6.1.tar.bz2 will be unpacked into a directory named git-1.6.1.
   
   From the command line the tar command would be something like:
   tar xjf git-1.6.1.tar.bz2
3. I want to install Git to /usr/local. I also want to be able to easily mange new Git installs and Git has lots of parts so I create a subdirectory for Git in /usr/local.
   1. Create a directory in /usr/local for the Git release, for example:
      sudo mkdir /usr/local/git-1.6.1
   2. Create a subdirectory for the Git release man pages, for example:
      sudo mkdir /usr/local/git-1.6.1/man
   3. If this is the first install of Git on the machine, create a symbolic link to the release directory:
      sudo ln -s /usr/local/git-1.6.1 /usr/local/git
      
      Going forward, /usr/local/git should always link to the release you currently want to use.
   4. Add /usr/local/git/bin to your PATH.
   5. Add /usr/local/git/man to your MANPATH.
   
   
4. Change directory into the unpacked source code, for example:
   cd ~/Project/git-1.6.1
5. Configure the build. Set the prefix to the directory the release should be installed into. For example:
   make configure
./configure --prefix=/usr/local/git-1.6.1
6. Build Git.
   make
7. Install Git.
   sudo make install
8. Don’t bother building the man pages. Get the matching man pages tar from http://kernel.org/pub/software/scm/git/.
   

   For example: git-manpages-1.6.1.tar.bz2.
   

   From the command line, unpack the tar into the install location, for example:
   sudo tar xjf git-manpages-1.6.1.tar.bz2 -C /usr/local/git-1.6.1/man

9. If needed, update the /usr/local/git symbolic link.

Windows

I don’t build from scratch on Windows. I’m currently trying out the msysgit package from Google Code.
