Default "Illegal Instruction"

This is a dandy. When I try to execute gnome-blackjack, the program fails
and returns "Illegal Instruction", but no other debugging information. Any
ideas about what this means? I've searched hi and lo with no result.

It happens sometimes to me when I try to use a binary compiled for a
Pentium-4 on a Pentium-3 machine. Maybe your binary was compiled with SSE2
enabled (gcc -mfpmath=sse -msse2 -mmmx) and your actual processor does not
support it.

I should have mentioned that blackjack worked fine about one week ago. I'm
using gnome version 2.8 from dropline and their gnome-games package.

Aha! Dropline at work, again! (Fault is Dropline did make some changes to
your X server when you installed Gnome. Dropline does that, you know. That
is why I have not messed with Dropline for a few years, now. I did not like
the way it interfered with my X Server files.

I haven't had troubles with my x server since installing dropline. What I
did, though, was remove their gnome-games package and compile it from
source and all works fine. I compile everything, including my kernel using
-march=athlon flag. I guess MF was right about this one.

Thanks for your comments

The Slackware-current changelog has this about GNOME distributions:

gnome/*: Removed from -current, and turned over to community support
and distribution. I'm not going to rehash all the reasons behind this,
but it's been under consideration for more than four years. There are
already good projects in place to provide Slackware GNOME for those who
want it, and these are more complete than what Slackware has shipped in
the past. So, if you're looking for GNOME for Slackware -current, I
would recommend looking at these two projects for well-built packages
that follow a policy of minimal interference with the base Slackware system:

http://gsb.sf.net
http://gware.sf.net

There is also Dropline, of course, which is quite popular. However, due
to their policy of adding PAM and replacing large system packages (like
the entire X11 system) with their own versions, I can't give quite the
same sort of nod to Dropline. Nevertheless, it remains another choice,
and it's _your_ system, so I will also mention their project:

http://www.dropline.net/gnome/

I will attribute the problems I'm now having with device permissions to
dropline, too. I hate that PAM keeps changing some of them whenever I
boot. Still, I can't be happier with my X installation and my Nvidia board
(after I dumped the stock agpgart driver). Nevertheless, I have been
thinking about upgrading to 10.1 and will try one of the other Gnome
packages, since I don't care for KDE. Thanks for your suggestions.
