Configuring Xcode 4

We currently use Xcode 4.6.1. You'll probably have the best results if you do too.
Add the projects you want to your workspace
If building for iOS, you need to edit your scheme to turn off implicit dependencies and parallel builds. Xcode 4 doesn't understand implicit dependencies with static libraries, so you'll need to add the dependencies to your scheme in the right order.
Take a look in the Workspaces directory for a sample workspace for the TextEditor iPad example app.

Supported Targets

We require iOS 6 and Mac OS X 10.7, but several bits of framework code implicitly require 10.8 for auto-layout or layer-backing fixes, or explicitly require them for things like NSXPCConnection.

Configuring the Source

We place our project-wide configuration options in xcconfig files, under OmniGroup/Configurations. The naming scheme of the files is fairly straightforward, hopefully. Each project has Omni-Global-{Debug,Release,...}.xcconfig as the basis for the corresponding configuration. Each Mac target has Omni-{Bundle,Application,Tool,...}-{Debug,Release,...}.xcconfig and each iOS target has Touch-{Application,Library}-{Debug,Release,...}.xcconfig. Each of these end point configurations when #includes 'superclass' configurations (with "Common" in the name).

Building from the command line

To build Debug versions of all the Omni frameworks:

cd OmniGroup
./Scripts/Build Frameworks

To build Release versions of all the Omni frameworks, instead do:

./Scripts/Build Frameworks install
