The following information is stolen directly from the Geoworks Independent
Software Vendor information packet (Document 1001). An electronic version
including a product order form is available on America Online, and a
professionally printed copy can be obtained at no cost from Geoworks at:
800 GEOS SDK - Order number for the Software Developer's kit
510 644 1621 - International SDK Number
More numbers and addresses are available in FAQ 1.
-------------------------
Q: How can I start writing applications for GEOS?
A: Writing applications for GEOS can be done simply by purchasing the GEOS
SDK. If your setup satisfies the minimum system requirements for the SDK,
you'll be all set to go. See the specification for the SDK for more
details on these requirements.
If you are just in the investigation stages of writing an application for
GEOS and don't have much knowledge of the system, then a good first step
would be to purchase the GEOS System Software Overview ($15). This
overview describes the system in technical detail and shows some sample code.
Q: Why is the SDK still referred to as Beta?
A: The tools of the SDK are still in the process of being refined.
However, Geoworks felt that it was important for the developer community
to make the tools available as quickly and economically as possible. The
tools in their initial release state are fully functional and of solid
quality. However, as with all software products, defects will be found as
most people will use the tools. Fixes for these problems will be available
in the developer forum and through various other mechanisms.
Q: What is the difference between the version 0.8 technical documentation
and the new release?
A: Prior to the release of the SDK to the general public, preliminary
versions of the documentation have been available to for purchase to the
general public. The first public release of this documentation was
numbered 0.7. Buyers of this documentation set have been upgraded to
version 0.8.
The documentation available with the SDK is also referred to as beta.
However, this documentation is complete and accurate to the best of our
abilities at the time of printing. This documentation set is the same as
what is included in electronic form on the CD ROM. For those purchasers of
the 0.8 release of the documentation, Geoworks has made available an
addendum to that documentation that will make that set current with the
new release.
Q: What does the SDK consist of and what type of hardware and software
will it require.
A: The SDK is shipped on a single CD ROM which contains the tools
necessary for GEOS development, include files, sample source code, and the
run-time environment for testing your applications. In addition, all the
technical documentation for the system and the SDK is included on the CD
ROM in various formats. Printed versions of this documentation may be
ordered from Geoworks for an additional charge.
Q: What is the FrameReader(R) browser?
A: The GEOS technical documentation set was written using FrameMaker(R)
product by Frame Technology Corporation. This is one of the file formats
the SDK is provided in on the CD ROM. The FrameReader is a Microsoft
Windows file browser allows you to view and print FrameMaker files. The
FrameReader browser is not required to view and print the documentation as
it is also provided in ASCII and PostScript format. The SDK package
contains information for ordering the FrameReader browser.
Q: Why is Microsoft(R) Windows(TM) recommended for the host machine?
A: There are two reasons for this. First, the FrameReader browser for
viewing and printing the online documentation files is only available in
the Microsoft Windows environment.
Second, the GEOS development tools run under DOS, not native under GEOS.
Microsoft Windows acts as an effective task switcher to allow you to go
quickly from one tool to the next. Windows PIF files and a Program Manager
group file are provided with the SDK for this purpose.
Q: What languages are supported? Can I program in C++?
A: The SDK allows programming in either C or Object Assembly language.
We've extended both of these languages with GEOS specific syntax for
defining objects, classes, message handlers, etc. The current version of
the SDK requires the Borland C++ compiler, version 3.1 to be installed.
The SDK, however, does not support C++. This is because GEOS is a
completely object oriented operating system while C++ is used to do object
oriented programming on non OOP systems.
Q: Do I have to write a program specifically for GEOS to take advantage of
its features?
A: Yes. To create a program that runs in the GEOS environment, your
application must be written specifically for the GEOS operating system API
(Application Program Interface). Standard DOS, Windows or other types of
applications will not run under GEOS.
Q: Can I port my Windows application to run under GEOS?
A: It's possible to port any application to a new environment and
therefore you could port your Windows application to GEOS. However, GEOS
is a radically different operating system and provides much more for
developers than Windows does. GEOS applications should be written to take
advantage of the sophisticated libraries and system services offered in
GEOS and should shed their Windows programs' baggage. If you try to port a
slow, 3 Meg Windows application to GEOS, you'll probably wind up with a
slow, large GEOS application. By making the most out of what GEOS offers
to application developers, you'll have a product that's small, fast, and
elegantly designed.
Q: What type of developer support and training will be provided?
A: Developer support comes in various formats including developer support
on CompuServe(R) and training classes in the use of the SDK and
fundamentals of GEOS programming. See the Independent Software Vendor
Support and Training Services page for more details.
Q: How can I get more information?
A: If you have additional questions or need more information, please write
or fax Geoworks Developer Support.
