Development of mGSTEP has been intermittent for more than 10 years.

Better maintained options may exist (see below) and should be considered for all new projects.

Alternate environments:

mySTEP is a fork of mGSTEP that has been developed as a platform for handheld mobile solutions. GNUstep and Cocotron are the two most active Open Source projects which provide Cocoa compatibility. Both target a broad set of features and are more likely to provide compatibility with modern environements. Microsoft's WinObjC bridge is a good option for iOS compatibility on Windows platforms.

• Cocotron is the basis for several Mac OS X applications ported to Windows.
• GNUstep is a GNU project with a long development history and a wide variety of extensions.
• mySTEP is developed for handheld mobile devices, development snapshots are released periodically.
• WinObjC implements many of the Core libraries and some Foundation classes underlying Cocoa.
