Apple is intentionally keeping the project file format (the project.pbxproj file in the bundle) the same for Xcode 4. The only difference is where the user and shared settings get stored, which we don't normally put in the repository... > But the main reason is that Xcode 4 compiles for 10.6 only (at least out of > the box), whereas Xcode 3 comes with the 10.5 SDK as well.

(i.e. build against the 10.6 SDK but warn for anything that was introduced after 10.4). That said, Xcode4 does not include the PowerPC compiler or SDK bits so you can only build Intel binaries - kind of kills things if you want to still support PowerPC... It also drops support for v2 NIB files, but that doesn't affect FLTK - NIB files are serialized object containers for Cocoa UIs... ________________________________________ Michael Sweet, Easy Software Products _______________________________________________ fltk-dev mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-dev
