I have been unsuccessful in attempts to make the Microport 286 DWB
work on my Enix 3.2 (now to be renamed OSIX :-Q). Did Microport do
something to AT&T COFF that makes it different from original AT&T
specs?
If the answer to the above is yes, is there a fix - either to the
binaries themselves, or a technical description of the Microport
binary file format? Folks at Everex tell me they'd like to build in
support for Microport 286 binaries if they know the file layout.
Thanks.

The binaries came directly from Intel in STL (Single Task Loadable) format. V/286 had special support for this type file (gen'd by Intel's development tools), but it was NEVER part of an AT&T standard. Why, do you ask, didn't Microport ever recompile the sources? Because we didn't have them. DWB/286 was version 1 from AT&T, DWB/386 was version 2. All we had was DWB-Ver2 source, and it didn't compile on the 286 :-( The code generated by Microport's 286 compiler DOES generate COFF files, and these files DO run under 386 Unix - both Microport's and all the other 3.2 releases. Everex shouldn't have to do anything to make those things work - ATT already did it. As for the STL format DWB, ha! Even I don't know what STL looks like internally. -John Plocher (BTW - I liked your .signature :-) >For a dollar you can still buy: A piece of paper with the Queen's face on it (in strange colours, though!)

You can port the 286 software development system and other commands if you want but the Documenters workbench is a bit tough. Since it is DWB version 1.0 anyway, I recommend that you buy it. -Mike Grenier mike@cimcor.mn.org

The DWB executables for SV/AT are NOT in COFF format, but in some funny
Intel semi compatible format. I don't remember the name... You can find
it in the /etc/magic file of SV/AT. As far as I know, they are the only
applications ever to have appeared in that funny format.
