Can someone please confirm that CodeWarrior for Linux is sensitive to
spaces in paths?
I had a mysterious compiler error that disappeared when I removed the
space from a path and re-added the file. I don't want to change
all my directories capriciously, since it will break all the other
platforms and ports for the product.
Many thanks.

Because C does not call anything automatically. You must call the C++
initialization code from your modules initialization routine.

Because then, you are calling the constructor yourself.
>How can I get a global instance sucessfully?
Use a pointer, as you already found out.
C++ can executes the constructors of global objects prior to executing
main. But you do not have any main() in your code, and even if you
would have a main() function, you would not call it from the usual
startup file crt*.
Perhaps you can look though the sources of crt and pick up the global
objects construction code. And then, you still have to add destruction
code. I am not sure, wether it is included in the normal crt*.

RHIDE is an IDE very much like that from Borland C/C++. Kdevelop is
another one that people seem to recommend a lot, though I've not used
it myself.

Hi,
I want to program a linux kernel into a flashprom and run it on an

You are ridiculous. Leave the spaces in filnames to the end users! No
reasonable developer puts spaces in path names in a source tree, especially not
under cross-platform development. I'd be beat up in the parking lot after
work if I did that!
I'd say that it's a bug that the IDE does not terminate immediately with a
diagnostic error message like ``You're a goofball, click OK!'' when it
encounters such a thing.

Subject: Q. Versions of cpio ?
Date: Wed, 28 Jun 2000 11:55:57 +0100
Hi,
I have recently installed version 2.2 of the Caldera distro, loaded the
2.2.15 kernel and applied two patches to get my OnStream DI30 tape drive
working. Next thing I want to do is get some nice verification of my
backups. Not sure if these are really the correct newsgroups to post to, so
any advice is welcome.
SCO OpenServer 5.2.0 which I use in work has the following option (from the
man page) -
-n Calculate the checksum value for each file read from an archive
(the
checksum value is equivalent to that produced by the command
sum -r). Filetypes other than regular files produce a checksum of
0
(zero). This option is intended to be used in conjunction with the
-itv options; the first entry on each output line is the checksum
of
an archived file.
This allows the a list of checksums to be read back after the backup is
completed, which can be compared with a list created with 'sum -r' before
the backup was taken. All of which soothes my rampant paranoia and lets me
sleep at night.
However, GNU cpio version 2.4.2 does not have this -n option. Does anyone
know of a version which I might be able to get hold of which does implement
this option ?
Alternatively, is there another way of verifying my backups ? I know
packages like BRU *say* they can verify it, but I'm paranoid and I like to
see the numbers ;-) Any experience would be appreciated, e.g. people who
have succeeded/failed in restoring systems with BRU.
Thanks in advance,
Martin.

Subject: DNS problems
Date: Wed, 28 Jun 2000 14:42:17 +0200
Hi !
I have Linux running off a Disk On Chip. With only 24 MB space for Linux
I built my own File System and got it up and running. Network
configuration worked fine except for DNS, wich I can't get to work. I
have my DNS Server mentioned in the /etc/resolv.conf File, but I can't
even ping the hosts in my local Network I specify in the /etc/hosts
File.
As I said, the rest of the networking is fine, I can ping inside and
outside my local network (routing works).
my questions are:
- are there any Files I could have missed when I built my file system
that
could cause these problems (!!ONLY!! with DNS) ?
- Is it possible that I compiled Name Resolution out of my Kernel
(Net device is a module), have heard that name resolution is
built into the Kernel, but haven't found any Information on it ?
- Can anybody think of other possible causes (solutions!) for my problem
??
Please anyone help me on this, I've been going mad on it for days!
thanks a lot for any answers!

I've read that rebuilt libraries and executables are needed, too. Do you

You apparently haven't read the responses to your previous post of
this question.
Short answer: No, there is no port of "Windows Media Player".
Microsoft has not (and probably will not) port this commercial product
to the Linux environment.
However, there are Linux packages that provide similar or identical
functionality. You have been referred to some of them.

Agreed! This is one abomination foisted on the world by Redmond, WA.
Another is toiling away, clicking on dialogs, "Are you SURE you want to
XYZ?". (No, I just asked you to do XYZ because I'm a Windows luzer,
clicking on anything that doesn't move.)

Do you mean that you can ping _any_ host by number, but _no_ hosts by name?

There is also /etc/nsswitch.conf, although I don't know how that could
cause your problem.

No. Name resolution is in glibc. (That also means that the subject is
off-topic for c.o.l.d.system ...)

You need to rebuild glibc (glibc 2.1.3 is needed) with the
2.4. headers installed but you don't need to rebuild dynamically
linked programs.

Thanks, but one more thing. If the send is within a thread, I'm
assuming that the thread can switch in the middle of the send w/o
locks or anything. My question is when the thread switches back to
where it left off in the send and the connection got broken in between
the switching, will the send(upon switching back to the thread) still
catch the broken connection?

As a developer using a commercial product - the MetroWerks compiler - I *AM*
an end user. And end users should be allowed and expected to put whatever
they damn well please in a filename, so long as it is OS legal.
It seems "reasonable" to point out that spaces in filenames in a cross platform
project is not a great idea because of prevailing limitations and assumptions
present in current in tools. Fine, I can accept that, and appreciate the tip.
To then imply that it is fundamentally ignorant or stupid to expect tools to handle
legal OS filenames suggests a different origin for the ignorance: that of the
user-hostile (i.e. "you're a goofball") community of programmers perpetuating the
assumption that no "reasonable" user - and, again, I *AM* a *USER* in this context
- would ever use the full range of OS legal filenames available to them. I'm sorry,
but expecting users to behave "reasonably" is not "reasonable."
Should I mandate 8.3 filenames, in all caps? Hey, no "reasonable" developer
uses long filenames, or mixed case..
