CodeWarrior and Xcode both support this feature with Prefix Headers. Precompiled headers are binary files that represent the compiler’s intermediate form of the headers required to compile a source file, providing faster compile times.
The information in the framework-style header should be limited to the common pieces that you can use throughout. This means that although CodeWarrior allows for a different prefix for each module, Xcode requires the same prefix file. An umbrella framework is a framework that includes a number of related frameworks. A framework is a type of bundle that packages shared resources, such as a dynamic shared library and its associated resource files, header files, and reference documentation.
#MSL EMULATOR MAC MAC OS X#
One important transition in moving to Mac OS X development is the switch from individual headers to framework-style headers in your source code files. Individual Headers to Framework-Style Headers Applications that use Mach-O format have access to all native Mac OS X APIs, such as Quartz and POSIX, and can more easily support symbolic debugging with GDB. Mach-O is the native executable format in Mac OS X. If an application uses an older operating system model and older operating system APIs that are not part of Carbon, it cannot run reliably in Mac OS X, except in emulation mode.Īfter converting your code to Carbon, you should do a Mach-O transition. Keep in mind that Carbon is a set of programming interfaces that allows applications to run natively in Mac OS X. You should first convert your code to Carbon using the latest version of CodeWarrior to smooth the transition. Think about an Automator script that performs:īefore you migrate a project to Xcode, you can take a few steps that will save you considerable time and effort later. Would you like to use compilers other than those currently supported by XCode. What are your experiences porting legacy code to OS X.
