Yes it does compile (under the configuration that I use). It most likely
also compiles under the configurations that lots of other people use.
What you probably meant to say was:
2.3.99pre3 - still won't compile under my configuration
or
2.3.99pre3 - still won't compile under all configurations
My response to the second is that there are just too many valid
configurations to check, even on an automated basis.
My response to the first is unprintable.

REQUEST FOR DISCUSSION (RFD)
unmoderated group comp.os.linux.embedded
This is a formal Request For Discussion (RFD) for the creation of a
world-wide unmoderated Usenet newsgroup comp.os.linux.embedded. This
is not a Call for Votes (CFV); you cannot vote at this time.
Procedural details are below.
Newsgroup line:
comp.os.linux.embedded Linux operating system on embedded hardware.
RATIONALE: comp.os.linux.embedded
It is becoming apparent that the Linux operating system has a
very bright future in the area of embedded applications; internet
appliances, wireless internet access, personal digital assistants,
television set top boxes, medical instruments, dedicated control
systems, etc. The potential for the growth of Linux in this area is
highlighted by the fact that roughly 95% of all newly manufactured
microcomputer chips are used for embedded applications.
Industry has already embraced Linux for use in embedded applications
for several reasons. The cost of licensing a commercial operating
system and the power of the open source development model are some
of the more prominent ones. The TiVo personal video recorder,
and the Empeg MP3 car player are two examples of consumer products
that utilize embedded Linux. Samsung has recently announced plans to
market the world's first Linux based PDA, named Yopy. Sony already
uses Linux based systems for developing applications for it's
Playstation2 game machine. The industry has further demonstrated
it's commitment to Linux by the recent announcement of the formation
of the Embedded Linux Consortium (ELC). It will consist of roughly
50 member companies including IBM, Lineo, Motorola and Red Hat.
Linux development has historically been oriented toward desktop
and server applications and the current comp.os.linux.* hierarchy
largely reflects this heritage. The unique nature of the technical
issues of using Linux for embedded applications, and the potential
for enormous growth are the two main reasons for the proposal of
this new Usenet newsgroup.
There will be some overlap of the charter of the proposed group
will that of the existing comp.os.linux.portable newsgroup. This
is unavoidable since some embedded devices are designed with the
intent to provide portable computing resources of a rather general
nature (PDAs for example). However, the universe of embedded devices
that would not be classified as a portable computer is very large
(e.g. TV set top boxes, medical instruments). It is the contention of
the proponent that the proposed group is sufficiently disjoint from
the existing comp.os.linux.portable newsgroup that the efficiency
and viability of both groups would not be negatively impacted.
Topics related to the use of Linux on embedded processors are
already frequently discussed in several existing Usenet newsgroups
and mailing lists. Statistics for such postings during the period
from Jan 1, 2000 to Jan 31, 2000 are shown in the table below. The
Usenet statistics were gathered using "Power" keyword searches
from the Deja search engine at http://www.deja.com/home_ps.shtml

CHARTER: comp.os.linux.embedded
The proposed newsgroup is intended to be a public forum for the
discussion of the development and use of the Linux operating system
on embedded hardware platforms. Topics considered appropriate for
posting to the group might include (but are not limited to);
o Software Related Topics
+ Embedded Linux distributions (e.g. Lineo Embedix, Mobile Linux)
+ Software APIs for embedded Linux development (e.g. Cygnus EL/IX)
+ Development of user applications for embedded Linux
+ Integrated Development Environments for embedded Linux
o Hardware Related Topics
+ Linux based emulators and debuggers for embedded hardware
+ Existing Linux support for specific hardware
+ Development of device drivers for embedded Linux
Topics that might appear welcome on the surface, but in fact are not
include; general questions about embedded hardware with no reference
to Linux, questions about embedded or real time programming that
are not specific to Linux, such as "What is multithreading?", or
"What is a deadlock?", etc.
One time postings of commercial product announcements or postings of
a commercial nature that are replies to another posted inquiry will
be considered appropriate. However, as in most other Usenet groups,
repeated or in-discriminant posting of commercial advertisements will
be prohibited. Postings using MIME, HTML formats are discouraged
since many Usenet readers do not use web browsers. The posting of
source code and binaries for the purpose of distribution shall be
prohibited. However, a small snippet of source code or a small patch
would be considered acceptable.
END CHARTER.
PROCEDURE:
This is a request for discussion, not a call for votes. In this phase
of the process, any potential problems with the proposed newsgroups
should be raised and resolved. The discussion period will continue
for a minimum of 21 days (starting from when the first RFD for this
proposal is posted to news.announce.newgroups), after which a Call For
Votes (CFV) may be posted by a neutral vote taker if the discussion
warrants it. Please do not attempt to vote until this happens.
All discussion of this proposal should be posted to news.groups.
This RFD attempts to comply fully with the Usenet newsgroup creation
guidelines outlined in "How to Create a New Usenet Newsgroup" and "How
to Format and Submit a New Group Proposal". Please refer to these
documents (available in news.announce.newgroups) if you have any
questions about the process.

Why don't you examine the slackware 7.0 distribution and locate the
.config file that Patrick used to build the kernel?

Subject: RedHat 6.1 and 3Com HomeConnect PC Digital Camera (USB), anyone?
Date: 30 Mar 2000 15:09:38 -0800
Ok, on an impulse I bought the 3Com USB PC camera. I've looked for
documentation and/or HOWTOs for connecting it to my pc running RH6.1,
but have been unsuccessful.
About the only thing I've been able to figure out is that RH6.1
doesn't appear to support USB "out of the box".
I refuse to believe that I'm going to have to wait until RedHat
releases a linux-2.4 distribution (RH7.x?), or that I'm going to have
to resort to Win98 and Netmeeting to get some use out of it.
Can anyone who's connected a USB camera to their PC and gotten it
working with RH6.1 offer me some pointers? Thanks!

[This is all off-topic for c.o.l.d.system.]
The default is built in to the compiler. Run
$ gcc -v -S -o /dev/null -xc /dev/null
to see it.
By the way, LD_LIBRARY_PATH and /etc/ld.so.conf affect the dynamic linker
(i.e., the runtime part), not ld(1) (the compile-time part).

| I don't think you need the netfilter "compat" options.
Have a realtime packet app, rewrote it from ipfwadm kernel interface,
though this might make it run in 2.4.
Thanks for the hint, compiles fine without the compat, but the app
doesn't run.

There is a difference between alpha test, beta test and
pre-production. At least in a real commercial software development
shop, or a well run university environment.
Linux has perhaps the best development team around, but but they do
code stuff without doing design first, and they not only don't do QA
before letting out code, they rejected an offer to have a group do it
when a new release was ready. I tried, not going to try again.

Subject: Floppy problems.
Date: 31 Mar 2000 00:19:22 GMT
I have been using the 2.2.14 kernel for a while but this week my
floppy drive has gone into a weird state.
I use the mtools packages a lot. I have been using them with 2.2.14 for
over a month without a problem. But this week I have a problem reading
from floppies. I haven't rebooted since this problem started so I can
experiment with this bug if someone wants to look into this.
I have no problem copying a file to a floppy with the mtools. (I can
read these files from the disk on a different computer). But when I try
to copy a file from floppy to my hard drive, the first 512 bytes are
corrupt. These 512 bytes happen to be the first 512 bytes in the file
that was most recently copied to a floppy.
Right now I can:
1) insert floppy A
2) use mcopy to copy file "foo.txt" to floppy A
3) replace floppy A with floppy B
4) use mcopy to copy file "bar.txt" from floppy B
The first 512 bytes of the new file "bar.txt" on my hard drive will have
the same first 512 bytes as "foo.txt".
If I then try to use "dd" to make an image of disk B. I will see those
corrupt 512 bytes starting from location 0x00004200. The rest of the
disk image looks ok (I haven't verified all of it).

you know, that DID occur to me ;-) I guess I'll go do that since at
least two folks think that's a good idea.
still, the better approach is to find out what magic is needed to put
that funky screen into normal vga text mode, then send that sequence
to the driver before the kernel gets too far in booting. I bet
someone will figure it out soon, given the popularity of the
linux-hack (and *bsd hacks) to the i-opener.
