The (highly unofficial) FIDONET OS2PROG C++ compiler pros and cons list
-----------------------------------------------------------------------
EMX 0.9a -- Contact : mattes@azu.informatik.uni-stuttgart.de
[ ] OS/2 Developer's Toolkit (*NOTE*) [ ] IDE (*NOTE*)
[ ] PM Class libraries [ ] Guidelines
[ ] Ships on CD-ROM (*NOTE*) [ ] Workframe (*NOTE*)
[ ] SOM support [ ] DirectToSOM C++
[ ] Intel 586 FDIV workaround
NOTES : You have to hunt for EMX. Most sites are not always up to
date, or carry the complete distribution. One of the CD-ROMs of the
Hobbes OS/2 FTP site comes with EMX pre-installed (the other does not).
Unfortunately, there is no author-supported site from which EMX can be
File Requested or downloaded. The author only distributes via FTP from
ftp.uni-stuttgart.de. Buying the OS/2 Developers' Toolkit is highly
recommended for PM work, since it includes PM documentation. The
author has stated that he has no intention of adding Workframe support,
and that his "IDE" is the emacs text editor.
PRO : Free (it's essentially the GNU compiler "rebadged"). Exceptional
support for porting UNIX applications to OS/2. Will develop OS/2 and
extended DOS applications. Lots of UNIX libraries, such as curses,
available. Exceptional support for POSIX.1. Good optimiser. Full
source to all libraries is available. Full source for the compiler
itself is available.
CON : Free (you get what you pay for, including the support). No 586
support. Development tools are as horrible as the UNIX originals, and
are strictly command-line based. Tools frequently default to UNIX, not
PC, standards, especially filename conventions (working from OS/2
programming reference books with EMX C++ is a challenge not recommended
to the novice). No PM support tools (help compiler, dialogue editor,
et al.). The DOS extender supplied doesn't work under OS/2 because it
uses VCPI. No printed manuals. No OS/2 API documentation. Excessive
reliance on extra tools (such as TeX and Emacs) that you have to go
hunting for.
Borland C++ 2.0 -- Contact : sales@borland.com (?)
(I still don't have a copy of BC++OS2 2.0 yet. An authoritative update
to this entry is thus still pending.)
[-] OS/2 Developer's Toolkit (*NOTE*) [*] IDE
[*] PM Class libraries [*] Guidelines (*NOTE*)
[*] Ships on CD-ROM (*NOTE*) [ ] Workframe
[ ] SOM support [ ] DirectToSOM C++
[ ] Intel 586 FDIV workaround
NOTES : Guidelines currently officially supports 1.01, but for 2.0
support all that you need to do is ask and it may well happen. Contact
Guidelines Tech Support on CompuServe for details. Borland has
integrated the OS/2 Developer's Toolkit into its own toolset. However,
it is a mishmash of the 2.0 version of the Toolkit (with some glaring
errors in the documentation) and the 2.1 version. The Borland Help
folder installed to the desktop contains the older buggy version.
PRO : Quick development and fast compilation. Very cheap. Neat and
easy to use IDE, that integrates editor, compiler, linker, debugger,
and API reference, and that allows you to compile and edit at the same
time. Good standalone PM debugger (Turbo Debugger GX), and standalone
text-mode debugger. Comes with Borland's own very good PM Resource
Workshop, including tools to migrate Windows resources to PM. Upward
compatibile with Borland C++ for DOS source (apart from recent changes
to C++). Will run on an 8Mb machine. Full source to all libraries
available. 32-bit in-line assembler (BASM) and standalone assembler
(TASM). Full run-time library source available (included in CD
version). Supports 586.
CON : IDE uses MDI paradigm, eating screen space. No support for
16-bit development (which rules out device drivers). Support for
calling 16-bit code (thunking) has serious bugs in. A lot of
non-standard items in the libraries and headers. Mediocre optimiser.
Resource workshop isn't as good as Borland *could* do. No support for
POSIX.1. Tools are counterintuitive for those coming from other
compilers/platforms (e.g. they don't use environment variables). Poor
technical support (bugs are rarely acknowledged). OWL for PM does not
support standard CUA91 controls.
Watcom C++ 10.0b -- Contact : sales@watcom.on.ca (FIDONET 1:221/186)
[*] OS/2 Developer's Toolkit [*] IDE (*NOTE*)
[ ] PM Class libraries [*] Guidelines (*NOTE*)
[*] Ships on CD-ROM (*ONLY*) [*] Workframe
[*] SOM support (*ONLY v1*) [ ] DirectToSOM C++
[*] Intel 586 FDIV workaround
NOTES : Guidelines currently officially supports 9.5, but 10.0 support
is in the pipeline. Contact Guidelines Tech Support on CompuServe for
details. Some parts of the IDE are Windows programs (although the
resource tools supplied in the OS/2 Developers' Toolkit may be
substituted for them).
PRO : Highly portable (Windows, extended DOS, OS/2, Netware, QNX).
Industrial strength optimiser. Has its own IDE similar to Workframe.
Develops for both 16 and 32 bit platforms. Supports 586. Able to
generate applications for multiple platforms from OS/2 with little or
no source changes. Able to debug DOS and Windows applications running
in separate sessions within OS/2. 32-bit assembler (WASM). Excellent
technical support (Watcom will ship patches to major bugs). All Watcom
patches are available from their FIDONET site. File Request FILES from
them for details. Comes with example demo programs for all standard
library functions.
CON : Non-standard linker. Printed manuals are extra and will almost
double the price of the product. You pay Bill Gates for at least three
of the bundled toolkits. Although there are fixes available, the
SOMObjects Developers' Toolkit supplied is only for version 1 of SOM,
whereas OS/2 WARP requires version 2 (installing version 1 SOM.DLL will
disable Workplace Shell -- be warned!). The documentation is badly
edited, repetitive, and in cases misleading. The technical support has
just been outsourced, and anything more than help for installing the
program and compiling the sample code (which is free) now costs a
significant amount.
Metaware High C++ 3.31a -- Contact : techsales@metaware.com
[*] OS/2 Developer's Toolkit [ ] IDE
[ ] PM Class libraries [ ] Guidelines
[ ] Ships on CD-ROM [*] Workframe
[*] SOM support (*NOTE*) [*] DirectToSOM C++
[*] Intel 586 FDIV workaround
NOTES : The OS/2 Developers' Toolkit 2.1 supplied supports SOM 1.
DirectToSOM C++, however, supports SOM 2. The SOM.DLL supplied with
High C++ is a later release than the one supplied with WARP, but the
WARP version may be used with no ill effect.
PRO : Highly portable (Windows, extended DOS, OS/2, UNIX). Supports
586. Industrial strength optimiser. Ships with the excellent Rogue
Wave Tools.h++ class libraries (with everything from strings to
databases). Excellent and detailed manuals. Proposed ISO C++ features
not in any other current compiler on any platform (namespaces,
iterators, case ranges, nested functions, pass-by-name, exception aware
classes). Supports customisable function calling conventions.
Supports per-thread variabl declarations. Excellent POSIX.1 support.
Excellent technical support (Metaware will ship patches to major bugs).
Supports developing Workplace Shell objects with DTS C++ (all DTS C++
headers for WPS are provided). Comes with example demo programs for
all standard library functions.
CON : Terrible text-mode debugger. No 16-bit support at all
(Pre-thunked versions of VIO16/MOU16/KBD16 are supplied, though). No
emitter to translate IDL to DTS C++.
IBM CSet++ 2.1 -- Contact : cset2@vnet.ibm.com
(Version 3.0 is currently in its second closed beta test.)
[*] OS/2 Developer's Toolkit [ ] IDE
[*] PM Class libraries (ICLUI) [*] Guidelines
[*] Ships on CD-ROM [*] Workframe
[*] SOM support (*ONLY v1*) [ ] DirectToSOM C++
[ ] Intel 586 FDIV workaround
PRO : *The* standard for OS/2 development. An industrial strength
optimiser. 586 support. Good thunking support. Excellent PM debugger
(IPMD). Toolset is easy to learn for those upgrading from Microsoft
compilers. Good technical support (the usual IBM CSD system).
CON : Demands enormous amounts of memory (16Mb is a working machine!).
No cross-platform compatibility. No support for 16-bit development (so
device drivers are out here too). No support for POSIX.1. Requires a
device driver in CONFIG.SYS for the execution profiler. The SOM
support supplied is only for version 1 of SOM, whereas OS/2 WARP
requires version 2.

Subj: What C++ Compiler ?
Attr: Scanned
-------------------------------------------------------------------------------
The (highly unofficial) FIDONET OS2PROG C++ compiler pros and cons list
-----------------------------------------------------------------------
GLOSSARY
--------
What is ...
... the OS/2 Developers' Toolkit ?
Available separately, this comprises the header files, link
libraries, sample source, API reference, and PM utilities for OS/2
development. IBM part number 61G1416.
... the SOMObjects Developers' Toolkit ?
The OS/2 Developers' Toolkit 2.1 only supports SOM version 1.x. SOM
2.x requires a different toolset, works differently, and uses IDL.
The SOMObjects Developers' Toolkit 2.0 contains a a SOM 2.0
compiler, IDL files, and documentation. It is available separately,
with IBM part number 59G5667 (check the version number when
ordering). Version 2.1 is due for release during December 1994, and
plans are in the works to integrate the SOMObjects toolkit with the
main developers' toolkit.
... the OS/2 Developers' Assistance Programme ?
The DAP is a subscription service from IBM that provides BBS
technical support, marketing and product information, and discounted
prices on OS/2 development tools to developers of OS/2 products.
... the OS/2 Developers' Connection CD-ROM ?
A common fallacy is that this is part of the DAP. Although DAP
membership gives cheaper subscription rates to DevCon, the DevCon
CD-ROMs are available on their own as single issues or as a yearly
subscription.
The DevCon CD-ROMs contain a wealth of source code, tools,
development utilities, and documentation for OS/2 programmers.
... Workframe ?
Again available separately, this is a compiler independent
development environment. Workframe is a means of managing projects,
and uses compiler-supplied DLLs to handle things like generating
makefiles, and displaying options settings notebooks for the
compiler, linker, and resource tools. It integrates with EPM (or
other editors) to allow you to edit source files at the point of
error. I've had two projects, one CSet++ and one High C++, both
being built *simultaneously* in Workframe.
... SOM ?
System Object Model. It's what drives Workplace Shell. It's a
language-independent run-time environment for class and object
support. See the DirectToSOM document and the SOMObjects Travel
Guide for more details.
... DSOM ?
Distributed SOM. This allows programs to share classes and objects
among themselves. See the DirectToSOM document and the SOMObjects
Travel Guide for more details.
... DirectToSOM C++ ?
DirectToSOM C++ compilers allow SOM classes to be defined and used
using standard C++ class syntax. See the DirectToSOM document and
the SOMObjects Travel Guide for more details.
... Guidelines ?
Like Visual BASIC ? You'll love this ...
You can obtain GUIDOC.ZIP, the introductory documentation for
Guidelines via FIDONET File Request from most Fernwood
Filebone sites, or via FTP from Hobbes.
