SCO is Still Distributing ELF, Part 4 STREAMS M & C's too
Wednesday, August 09 2006 @ 11:05 AM EDT

I know. This is ridiculous. But I'm hearing that SCO is still distributing ELF. Here's the latest that was sent to me:
SCO is distributing GDB 4.12 at, which contains bfd, including ELF reading code. The code is not an exact replica of that in binutils but they appear to share a common ancestry.

So, more evidence gobbling ahead for SCO, methinks. In case you are interested in Skunkware, by the way, there's an interesting presentation about it, titled "Open Source and SCO" at SCO's FTP site here: The presentation was given at an earlier SCOForum by Ronald Joe Record, Open Source Program Architect, The Santa Cruz Operation. Here's the COPYING file, the good old GPL. I thought I'd list some highlights, since the poor presentation probably isn't long for this world. As soon as Groklaw publishes these addresses, SCO sweeps them off the Internet.

Speaking of which, I'm told SCO is distributing STREAMS methods and concepts, some source code that demonstrates how to write a STREAMS driver on .

A whole lot of methods and concepts going on there. [Cf. Groklaw's recent article on STREAMS.] By the way, there is some SCO documentation with a very helpful page on STREAMS. Knowledge made freely available is a wonderful thing, don't you think?

Here's just some of the contents in the Ron Record presentation, just for the record:

This Presentation

SCO has SCO OpenServer Documentation, called DocView still up on the Internet here. There is a page on GNU development tools, and lookee here: binutils. I guess they can't say they didn't know what binutils was, that it came in the GNUtools package, and that it included ELF. The copyright on the documentation is 2003 Caldera International, Inc. (SCO OpenServer Release 5.0.7 -- 11 February 2003). That's a month before Caldera, now SCO, sued IBM. And they provide a helpful link to, so they certainly know it's all GPL.

But just in case they try to say they didn't know, here's a 2004 presentation from SCOforum in which the slides show binutils in GNUtools. [Update: As is their wont, SCO has removed the slides from that link. However, you can still find the slides here.] It's listed clear as a bell on the slide titled Open Source Components in OpenServer gnutools package, binutils 2.15.90. You can find it listed also in the slide titled Open Source Components in UnixWare OSTools Package, which lists both Gcc and binutils 2.10.1.

Why is SCO so careless? The first rule of story telling, if one is so inclined, is to make sure you aren't caught in the truth. Linus said once that the Open Source method encourages truthfulness. I believe we have just demonstrated that in our ELF series, which by the way isn't finished. SCO forgot about all those Open Source eyeballs. It's a tremendous advantage to Open Source, and it's the fuel of Groklaw.

SCO told the court some stories but it neglected to clean up all the contrary evidence. Why? One can only speculate, but I think it's because they made a big mistake thinking that Linux folks were no longer needed. They trimmed the engineers and there is nobody there to warn them, or nobody motivated to do so. And now, should this pile of inanity ever reach a jury, I don't think the jury will like what it hears. Judges either.

And what about SCO's experts, who backed SCO up on this inanity about ELF and STREAMS, etc.? Whatever do you think the judge and jury will think of them now? Probably the same thing you are thinking.
