InstallingX Code

XCode installation

Install XCode via the Mac App Store, just as for 10.7 and 10.8. See details below.

Command line tools

To install the command line tools, after you have installed the free XCode app, run the following command in a terminal window:

sudo xcode-select --install

and follow the on-screen instructions.

On OS Lion and Mountain Lion you must "purchase" XCode from the Mac App Store. It is free, so no costs are involved, but it is pretty big - the download size is 4.5 Gb.

Open the Mac App Store (App Store in your Dock), search for XCode, and "buy" it by clicking the Free button. It will then start downloading and install itself.

You need an Apple ID/account to download things from the Mac App Store, but no credit card information is needed as long as you only install free apps, like XCode.

Command line tools

To install the command line tools that comes with XCode (and which are needed by our infrastructure), open XCode (e.g. from the Launchpad). Then, go to Preferences ➔ Downloads and select the “Components” tab. There you can choose Command Line Tools and click the Install button. This takes some time, but then you are done.

XCode is availabe on the DVD that came with the computer. Please insert the DVD, and look for instructions on how to install optional packages. Then install the XCode package.

If you can't find the original DVD, it is also available from Apple  - registration is required but free.
