Be Demonstrates VirtualMac For The Be Operating
New technology from Fredlabs, Inc. will provide a bridge for customers and developers
making the transition to the BeOS.
At Macworld Expo, Be Inc. demonstrated technology that allows the Be Operating
System (BeOS) to run System 7.x MacOS applications directly within its multitasking,
multiprocessor environment.
Developed by Fredlabs, Inc., a software company based in San Francisco, VirtualMac
allows both modern BeOS applications and current System 7.x applications to be active
at the same time, and for data to be exchanged between the systems.
Last August, Be announced it would enhance the BeOS to provide support for a wide
variety of PowerPC based systems, including those based on Apple's PowerMacintosh
designs. The company began shipping the BeOS for PowerMac development kit to
software developers last month. Be has committed to delivering "dual-boot" capability
- the ability to run both the BeOS and MacOS (or any other system) on a single
machine - when it delivers the first public release of the BeOS in the first calendar
quarter of 1997. The company has also committed to delivering the ability to access
Mac formatted disks within the BeOS, as well as data file compatibility and Internet
compatibility between the two systems.
However, VirtualMac capabilities go a step further - adding the ability to run System
7.x applications directly within the BeOS environment. During the Expo, Be and
Fredlabs demonstrated Microsoft Word and Excel, ClarisWorks, and other applications
running within the VirtualMac environment.
To provide the System 7.x capabilities, VirtualMac creates a set of processes within
the BeOS which, to MacOS applications, look like a Macintosh environment. In this
way, VirtualMac is simply another task within the BeOS system. The implementation
makes use of the MacOS ROMs found in PowerMacintosh hardware designs, within
PowerMac clones, and within future systems based on the PowerPC Platform (PPCP or
CHRP) design.
The companies stated that it will take further study to determine how far the
multitasking and multiprocessor capabilities inherent in the BeOS can be used within
the VirtualMac environment, and the limits on compatibility with certain classes of
System 7.x software. However, early results are encouraging, and one benefit is
immediately apparent: If the VirtualMac environment encounters problems, it can be
shut down and rebuilt without rebooting the BeOS system or the hardware.
Objective-C and Ada95 Now Available for Power Mac
MachTen CodeBuilder - An affordable software development tool for the next
generation MacOS
Tenon Intersystems has extended MachTen, its highly-regarded unix system for Apple
computers, to include the Objective-C and the GNAT-Ada 95 tool suite. MachTen
CodeBuilder, a new offering from Tenon, includes C, C++, Objective-C, Java, Ada95
and Fortran77. CodeBuilder can be used in combination with standard Macintosh
editors and compilers to develop Macintosh applications, X applications, and unix
applications.
MachTen CodeBuilder extends MacOS with a family of dynamically-linked, shared
libraries that, like a Java virtual machine, create a unix virtual machine-based
execution environment with pre-emptive multi-tasking. Tenon's MachTen unix is
based on the same Carnegie Mellon Mach and BSD unix foundation as Steve Jobs' NeXT
OS, making CodeBuilder a good platform for porting and building next-generation
MacOS applications.
The native PowerPC (PPC) package contains a complete unix software development
environment with a source-level debugger and C, C++, Objective-C, Ada95 and
Fortran77 compilers all generating native PPC code. Since CodeBuilder creates binary
PowerPC Executable Format (PEF) files that can integrate directly with other
Macintosh development tools, software developers can combine Macintosh debuggers
and compilers with the CodeBuilder tool suite to get the best of both the Macintosh and
unix worlds.
CodeBuilder is a powerful tool for porting existing unix applications or developing
new, advanced applications on Power Macs and Power Mac clones. This unique toolset
gives developers the ability to create an application with a single source base not only
for Power Macs under a native Apple operating system, but also for Silicon Graphics,
SUN, NeXT, or HP environments. CodeBuilder gives Apple developers the freedom to
take advantage of time-tested unix development tools without giving up the features of
their favorite Macintosh editors or compilers.
Objective-C, an object-oriented extension to the C language, is the NeXTStep
development language. The GNUStep OpenStep base class library is included on the
CodeBuilder CD as a source code compilation example. GNUStep is a widely-available
implementation of OpenStep, the NeXT distributed application run time environment.
The fact that CodeBuilder's Objective-C is able to build and execute large sections of
the GNUStep library demonstrates the strength of CodeBuilder's Objective-C
implementation.
Metrowerks & Apple Computer Sign Development
Agreement For Porting Codewarrior Tools To
Rhapsody, Apple's Next Generation OS
Metrowerks Inc. and Apple Computer, Inc. entered into a development agreement to
accelerate support for Apple's next generation operating system ("Rhapsody") in
Metrowerks CodeWarrior integrated programming environment ("IDE"), development
tools and compilers. Upon completion, Metrowerks will provide MacOS developers a
full CodeWarrior solution comprising compilers, programming tools and debuggers
for the development of applications for both MacOS and Rhapsody.
CodeWarrior compilers will build Rhapsody applications in the current CodeWarrior
IDE hosted on MacOS. Metrowerks expects to have CodeWarrior Objective C compilers
and Objective C runtime support in its CodeWarrior C++ compilers running in the
CodeWarrior IDE hosted on MacOS System by May 1997 for the Apple Worldwide
Developers Conference. Metrowerks will include these new CodeWarrior programming
tools and compilers supporting Rhapsody as part of its regular CodeWarrior for MacOS
subscription at no additional charge to CodeWarrior for MacOS subscribers.
The CodeWarrior IDE, programming tools and compilers will be ported to Rhapsody.
Metrowerks' CodeWarrior IDE will be hosted on both the MacOS, as currently
available, and on Rhapsody. The first developer release of the CodeWarrior IDE hosted
on Rhapsody is scheduled for release in January 1998 at MacWorld San Francisco.
Upon completion of porting the CodeWarrior IDE to Rhapsody, both the CodeWarrior
IDE hosted on MacOS and the CodeWarrior IDE hosted on Rhapsody will build MacOS
applications running on 68K and PowerPC, Apple's New OS applications running on
PowerPC, and Windows95/NT applications running on x86.
Metrowerks intends to add cross-platform support so that the CodeWarrior IDE hosted
on the MacOS will allow developers to build Rhapsody applications, while the
CodeWarrior IDE hosted on Rhapsody will allow developers to build MacOS
applications.
Metrowerks PowerPlant application framework will be transitioned to Rhapsody.
Metrowerks and Apple Computer intend to outline and implement a transition strategy
that will allow developers using Metrowerks' PowerPlant application framework to
move their applications to Rhapsody as rapidly as possible.
