Subject: What *doesn't* work under linux
Date: Wed, 2 Dec 1992 09:15:38 GMT

Okay, I have read the FAQ and discovered what works (GNU stuff, X,
TeX, etc).  I also know that some things aren't there yet (tape devices
and the rest).  What I want to know is, is there any software that people
just *can't* get up and running under Linux?  I ask this because there
is stuff I am interested in running (I don't have a system yet) but it
isn't on the 'runable list'.  This means nothing of course, I am just
curious to see if there is a 'not-runable' list.

Based on comments here and what I know about Linux, the biggest
problem is going to be with code that departs from the core of
"standard" Unix.  Typical problems are

   specific System V features:  semaphores, messages, shared memory,
        locking
   recent Unix system facilities present in only some versions, e.g.
        mmap (Sun shared memory), streams modules

It looks to me like the most serious problem is likely to be with
commercial applications that use shared databases.  This is what the
system V facilities were invented for.  You could fake a lot of them
with a complete implementation of mmap, but I don't know when that
will be available.  I've heard rumors of people working on some of the
system V facilities, but haven't heard anything about it.

I'm just dipping into this newsgroup now, and found that it's easy to
get a "#" prompt staring at me once the boot disks are downloaded.

But the distribution packages all look rather overwhelming and in a
constant state of change, so it's not all that appealing except as a
"real programmer's" hacking system.

So what I really want to know on this thread is:

        Does/will Linux support the USL SysVr4/386 ABI?

If it could run the same binaries as all the USL clones (e.g. at our
workplaces), then us home users' lives would be much easier.

It does not.  I might, but Linus has little or no documentation about
it.  Is such documentation available for free, or as a book?

As a feature, I can understand it, but I still think binary
compatibility is rather unpleasant as a thought, especially when
coupled with backwards compatibility.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO v IBM.
