Building a Grand Unified Xcode 4.4 installer for both Lion and Mountain Lion

Apple has released Xcode 4.4 through the Mac App Store for all Macs running 10.7.4 and higher, including Mountain Lion. This application, on first launch, then installs the other Xcode tools. The command line tools can be installed separately through the Xcode preferences, in the Downloads section.

For my users who are developers, I wanted to include Xcode 4.4 in their new machine builds and also install the command line tools automatically. I also wanted to build one Xcode 4.4 installer that worked for both 10.7.x and 10.8.x. The Xcode 4.4 application itself runs fine on both Lion and Mountain Lion, but the command line tools are OS-specific.

To do this, I used a modified form of the methodology referenced in this post to repackage Xcode 4.4 for distribution without needing an Apple ID. See below the jump for the procedure.

Building the package

Install Xcode 4.4 from the Mac App Store onto your build machine.

Update – 7-31-2012: I’ve seen Apple ID-related issues with updating the Mac App Store’s Xcode since posting this, where I was signed into the App Store using a different Apple ID than the one used to install Xcode. To avoid this problem, download and use Xcode 4.4 from the Apple Developer site.

Download the latest Lion and Mountain Lion Command Line Tools for Xcode disk images from the Apple Developer site

Verify that the permissions on the Xcode application in /Applications are correct by running the following command:

sudo chown -R root:wheel /Applications/Xcode.app

Set up a new Iceberg project. Since we’ll need to run this installer with root privileges, I recommend setting the project type to Darwin: Package. That will open the project with the installation privileges automatically set to root.

In this case, I’m naming the project Xcode 4.4.

In the Files section, click on the Applications folder in the listing.

Go to the Archive menu and select Add Files…

Select the Xcode application in /Applications

Verify that it’s now showing up under Applications in your Iceberg project

Select the Lion and Mountain Lion Command Line Tools for Xcode disk images and drag them into the Additional Resources section of your Iceberg project.

The last pieces are removing any previous Xcode.app from /Applications and telling the correct Command Line Tools for Xcode installer to run.

To remove any previous Xcode.app from /Applications, I’m using the following preflight script:

#!/bin/sh

# Remove existing /Applications/Xcode.app from machine

if [ -d /Applications/Xcode.app ]; then
  rm -rf /Applications/Xcode.app
fi

To install the command line tools, I’m using the following postflight script:

#!/bin/sh

# Determine OS version
osvers=$(sw_vers -productVersion | awk -F. '{print $2}')

if [[ ${osvers} -eq 7 ]]; then

#
# Installing the Xcode 4.4 10.7 Command Line Tools
#

# Create /tmp/Command Line Tools (Lion) mountpoint in /tmp

  /bin/mkdir "/tmp/Command Line Tools (Lion)"

# Mount the latest command line tools disk image as /tmp/Command Line Tools (Lion)

  /usr/bin/hdiutil attach "$1/Contents/Resources/xcode44cltools_10_76938107a.dmg" -mountpoint "/tmp/Command Line Tools (Lion)" -nobrowse -noverify -noautoopen

# Install the Xcode command line tools

  /usr/sbin/installer -dumplog -verbose -pkg "/tmp/Command Line Tools (Lion)/Command Line Tools (Lion).mpkg" -target /

# Clean-up

# Unmount the command line tools disk image from /tmp/Command Line Tools (Lion)

  /usr/bin/hdiutil eject "/tmp/Command Line Tools (Lion)"

# Remove /tmp/Command Line Tools (Lion) from /tmp

  /bin/rm -rf "/tmp/Command Line Tools (Lion)"

fi


if [[ ${osvers} -eq 8 ]]; then

#
# Installing the Xcode 4.4 10.8 Command Line Tools
#

# Create /tmp/Command Line Tools (Mountain Lion) mountpoint in /tmp

  /bin/mkdir "/tmp/Command Line Tools (Mountain Lion)"

# Mount the latest command line tools disk image as /tmp/Command Line Tools (Mountain Lion)

  /usr/bin/hdiutil attach "$1/Contents/Resources/xcode44cltools_10_86938106a.dmg" -mountpoint "/tmp/Command Line Tools (Mountain Lion)" -nobrowse -noverify -noautoopen

# Install the Xcode command line tools

  /usr/sbin/installer -dumplog -verbose -pkg "/tmp/Command Line Tools (Mountain Lion)/Command Line Tools (Mountain Lion).mpkg" -target /

# Clean-up

# Unmount the command line tools disk image from /tmp/Command Line Tools (Mountain Lion)

  /usr/bin/hdiutil eject "/tmp/Command Line Tools (Mountain Lion)"

# Remove /tmp/Command Line Tools (Mountain Lion) from /tmp

  /bin/rm -rf "/tmp/Command Line Tools (Mountain Lion)"

fi

Once you’ve got the preflight and postflight script built, run the following commands to make the scripts executable:

sudo chmod a+x /path/to/preflight

sudo chmod a+x /path/to/postflight

Last step, go ahead and build the package. (If you don’t know to build, check the Help menu for the Iceberg User Guide. The information you need is in Chapter 3 – Creating a package.)

Testing

Once the package has been built, test it by taking it to a test machine running 10.7.4 or higher that doesn’t have Xcode 4.4 and install it. The end result should be that Xcode 4.4 installs along with the correct command line tools for the host without requiring an Apple ID.
