NeXT-to-Windows porting eased

by Simson L. Garfinkel

Newark, CA NeXT developers can now use Stepstone Corporation's Objective-C compiler with Borland International's Turbo C to port their applications from NeXTSTEP to DOS and Windows, thanks to a new set of Objective-C extensions developed by Berkeley Productivity Group.

Until now, Objective-C on DOS could be done only with the Microsoft C compiler. But the Turbo-C compiler is superior, said Berkeley President Christopher Lozinski. "Microsoft doesn't support memory management very well, and Windows has fragmented memory." The extensions will cost $495, including the Stepstone compiler.

Any NeXTSTEP program ported to a PC would require a new user interface, said Lozinski, since his company has not ported the NeXTSTEP user interface objects. Lozinski is working on a solution to allow developers to build interfaces with Smalltalk. Lozinski is also working on a version of Suite for the Borland Objective-C extensions, which will allow Objective-C programs running on a PC to transparently send messages to Objective-C server programs running on NeXT computers.

Suite, developed by Suite Software of San Diego, is functionally similar to NeXTSTEP 3.0's Distributed Object system.
