Assuming PC hardware, with a standard VGA type card, this is not a
standard function. I think there is a bit in one of the control registers
which changes the meaning of the blink bit to mean bright background?
Does anyone know how to do this using standard linux control codes or
IOCTL calls?
Failing that mail me and I will lookup the details.
Of course doing this will break switching between multiple consoles!!

Please dont!! A full screen refresh is what, about 4KB, with a modern
system (say newer then a 386) screen refresh time using a decent library
(curses or slang) is still tiny! Doing this also seriously breaks vts and
xterms, not to mention telnet logins, and VT220's on serial ports! This was
a reasonable approach with MSDOG but would seem to break lots under unix!

Yes, Netscape is available. (Mozilla is not nearly production-quality
yet, from what I've seen, but there is no reason it shouldn't build on
LinuxPPC. I haven't tried doing so yet, though.)

There is also Yellow Dog Linux. YDL doesn't have Netscape working yet on
their distro, though. (I would wait for LinuxPPC R5 to come out,
hopefully within the next few weeks.)
Yes, LinuxPPC and YDL both use a kernel built from the same sources as x86
(and Alpha, and Sparc, and...).
Like (essentially) all versions of Linux, the Mac Linux distributions run
X. They also run all the various window managers, desktop environments
like KDE, GNOME, etc.
Really, LinuxPPC is essentially the same as Linux on x86, except that it
is compiled for a different processor. It has been a little behind the
x86 distributions in some ways, e.g. it has been slow to move to glibc2,
but this is changing with the new R5 release.
Cordially,
Steven G. Johnson

There are no real good Mac-emulation software available. Both Executor
and vMac are O.K. for some old programs, but if your school is heavily
Mac, you will need something that can run PowerPC apps, and at the
moment, only a real Mac will do.

Linux runs pretty well on Macintosh. Much of the Linux software is
source compatible with PowerPC. As someone who uses LinuxPPC and
Linux/X86 on a daily basis I realize that it's a pain sometimes having
to compile your things but on the whole LinuxPPC is a pretty good
proposition. Also, there is a project to run MacOS under LinuxPPC called
SheepShaver (www.sheepshaver.com) and if it works, you'll be able to run
Mac apps from a MacOS window in Linux. Good Luck.

Arrrrgghhh!!!!
It indeed doesn't work since the /lib/ld-linux.so.2 from glibc-2.1 refuses
to (run-time-)link with glibc-2.0 and this path is hard coded in the
executable.

I wish I knew. I found it (labelled something to do with MkLinux) while
busily hacking about to try and figure out how to get my keyboard to make
better sense (for instance, ignoring the distinction between left and
right modifier keys- it's unhelpful that Linux thinks only my left shift
counts- or was it right?)
This keyboard mapping had _everything_ working right. I've never been
able to get _any_ keyboard mapping correction to stick, and xmodmap seems
to not work run from rc.conf (possibly because I'm not running it
properly). 'More will be revealed', hopefully before long.
When I talk about ultimate I mean 'everything works normally' which is
far from what I currently put up with everytime I boot into linux- I went
with a Red Hat-like install I downloaded from linuxppc, and there was no
'MkLinux' option for keyboard so I just picked 'US' which is clearly
wrong.
I'd love advice on how to straighten this out. I've yet to see any, and
might just have to hack it into quivering bits of linux myself and become
the authority if I can't find anybody who can tell me how to get the
keyboard working right. That would, I think, be the traditional approach,
right? All I know is that my keyboard mapping is _very_ wrong when treated
as straight 'US' mapping, and I need it to be the MkLinux mapping and
can't get that to stick (or indeed to happen at all). xmodmap changes
don't stick either.

There is Yellow Dog Linux. That seems to be gathering a following. As
for window managers.. LinuxPPC ships with a bunch. KDE is set as
default. KDE comes with several apps and is pretty good, although it
uses a fair amount of memory. Still, the K apps are fairly well
integrated. You can set up fvwm, fvwm2, Afterstep, AnotherLevel right
out of the box, or you can DL others.

Depends on which linux distribution you have. For Redhat Linux you need
"glibc-devel". One way to find this out is at

I cannot say I think it was screwed up and glibc-2.0.x was never announced
as the final, definitive and whatever version. In addition no-one ever urged
people to upgrade, neither from libc5 to libc6 nor from 2.0.x to 2.1.x which
is probably much less work in progress than 2.0.
Regarding distributions based on 2.0 ... well, again just my personal
opinion ... perhaps more the need to bring out something new (?)
As far as commercial software is concerned though it would be nice at least
if vendors would not only say "runs on glibc systems" but too if it does not
(yet) with anything beyond 2.0.7. Especially since other stuff, here the
Motif shared libraries and programmes linked to it, Netscape, the whole
X Window package and other things work fine.
Minor note, disabling the embedded font server of Applix, after some strace
sessions and other fun, was enough to make it happy now and this system is
100 per cent glibc-2.1.1pre1.
Second minor note, glibc-2.1.x is right now probably most interesting to
developers since it is much more standards compliant than anything else
before and it is a great job. As a `just' user though you might as well
take your time.
Cheers,
Juergen

To be fair to the previous poster, the subject was instantiating template
in a source file outside the header file. This is something that egcs
doesn't do well right now, unless you compile without explicit templates
and instantiate yourself (as Greg was demonstrating in his posting) -
which I think everyone who has done so would agree is a pain.
As near as I can tell, allowing compilation of function/class templates
whose definitions are not visible at compile time (i.e. in the header
file) will have to wait for the 'export' keyword to be fully implemented.

Subject: Library problem

I have a RH 5.1 system w/ kernel 2.0.36, running on a PII.
Installing these packages (from the RH contrib tree):
XFree86-3.3.3.1-2.i686.rpm
XFree86-SVGA-3.3.3.1-2.i686.rpm
XFree86-devel-3.3.3.1-2.i686.rpm
XFree86-libs-3.3.3.1-2.i686.rpm
xanim-27070-with-closed-codecs-1.i686.rpm
renders X (and with a working X, xanim) unusable. They complain about
unresolved library symbols, namely
__register_frame_info
__deregister_frame_info
and (of course) refuse to run.
The libc version is glibc-2.0.7-29.
Could someone point me towards the relevant directory updates ?

You are mixing programs or libraries (or both) compiled by
gcc and egcs. Unfortunately this sometimes doesn't work.
One solution is to pick through the programs and libraries
to find out where this symbol is required and resolved,
then make the appropriate fix; another is to get a entirely
consistent set; also there is a hack that may work for you
