Xcode 4.3 was released<\/a> on February 16th. It is now truly a Mac App Store application.<\/p>\n

\nWith Xcode 4.2, you downloaded an “Install Xcode” application from the Mac App Store, which in turn “installed” Xcode in the usual location, “\/Developer”, which is a folder named “Developer” at the root of your hard drive.<\/p>\n

\nFurthermore, if you wanted Xcode to automatically update (from the Mac App Store), you had to keep the “Install Xcode” application (1.8 GB) in your Applications folder, as that was what the the Mac App Store actually updated; you then had to run “Install Xcode” manually to update.<\/p>\n

\nThis has changed for the better.<\/p>\n

\nXcode.app now installs directly in the Applications folder. In fact, it will helpfully propose to move the older, obsolete installation to the Trash for you:

<\/p>\n
\n\"Xcode\n<\/div>\n

<\/center><\/p>\n

\nXcode is also smaller, since a lot of (probably) lesser-used software has moved to optional downloads. Peter Hosey has a comprehensive list<\/a>.<\/p>\n

\nIn my case, I had one more thing to do: install the command-line tools. They can be found in Xcode > Preferences > Downloads > Components. To get them working properly, here is what I had to do:<\/p>\n

    \n
  1. sudo xcode-select -switch \/Applications\/Xcode.app<\/code>
    This updates the command-line Xcode tools to point to the new location, and is only important if you are migrating from 4.2. A new install should work fine.<\/li>\n
  2. Install autoconf. Some of my projects (and many unix-based ones) use autoconf<\/a> to generate ‘configure’ files, and this tool is missing from the new install. It was present in earlier installs, so I have filed a radar<\/a>.
    In the meantime, I was able to     download the latest version<\/a> (2.84 at the time of this writing) and install it with the usual .\/configure; make; sudo make install<\/code> dance<\/li>\n

  3. Update any scripts that have a hard-coded ‘\/Developer’ path.
    Since everything is in the ‘\/Applications\/Xcode.app’ bundle, the new path is ‘\/Applications\/Xcode.app\/Contents\/Developer’. If you don’t want to hard-code it (for instance, if you use Xcode 4.3 but your colleagues are still on Xcode 4.2), you can use the output of xcode-select --print-path<\/code> to find the path to ‘Developer’ on any system. This works in Xcode 3 as well.\n<\/ol>\n
