What versions of Mac OS X, Xcode, development SDK, and gcc are supported for building Camino?
A. There is a constantly-updated matrix of working build configurations on the Mozilla Wiki. However, Camino officially supports building with Xcode 2.4.1 or higher, 10.4u SDK, and gcc 4 on Mac OS X 10.4.11 or 10.5.1 (Xcode 2.5 recommended for Mac OS X 10.4.11, and Xcode 3.0 recommended for Mac OS X 10.5.x), and these build instructions and the default .mozconfig settings expect build environments to conform to these requirements. Your build will fail if you do not adhere to these requirements or make all the configuration changes required for another working configuration.
