Mac software development application CodeWarrior is heading to oblivion, manufacturer Metrowerks has said.

The final version of the development environment (which is now owned by Freescale Semiconductor), CodeWarrior 10, will be released this autumn.

CodeWarrior was previously the de facto standard for developing applications for Mac, and enabled cross-platform development because it was also available for other computer platforms.

Ars Technica reveals a note on Apple's developer mailing list that confirms the news, adding that CodeWarrior 10 will "probably be released as a download only at a low price".

The software will not compile code for Intel processors, and limited support will only be available until the end of the year.

The news means developers will have to port projects from CodeWarrior into Xcode in order to build software for future Macs.

Microsoft and Adobe are believed to use CodeWarrior for application development.

The shift to Intel processors was revealed at Apple's Worldwide Developers Conference in June, CEO Steve Jobs said that the first Macs with Intel processors would appear next year, with the migration to Intel expected to be mostly complete by the end of 2007.

He said: "I can confirm the rumours that every release of Mac OS X has been compiled for PowerPC and Intel. This has been going on for the last five years".

Jobs also encouraged developers to adopt Apple's homemade Xcode development environment in order to build applications for PowerPC and Intel processors.

Now developers have no choice.

To help them, Apple recently published an extensive document detailing the process of porting projects to Xcode from CodeWarrior.

Metrowerks has been approached for confirmation of the news, but has not yet responded.
