Hi,

I've ddd 3.1.3 and lesstif 0.88 compiled in to be compliant with Motif
1.2 on a RH 5.2 machine. Every time I try to edit
preferences, the following message appears :
        Warning: 
        Name: menubar
        Class: XmRowColumn
        RowColumn.c(3547) - Restoring focus to NULL widget!
        Must have missed a focus save somewhere.

And then if I try to change anything in the popup, the border of the
the small popup window blinks continuously and ddd hangs.

I'm wondering if this problem is ddd's or lesstif's?

Also, the cursor is always the dotted vertical line instead of the
solid line that I normally get on another machine. NOrmally that
indicates that the mouse is not inside the window, but I can still
type things inside the debugger window. Is something wrong with my 
pointer focus setting?

thanks.

The documentation you are looking for should have been included in the package
you downloaded and installed.  Understand that I am using emx/gcc under OS/2,
so I do not know exactly where you would find the files or even what they
would be called.

The c library references are for emx, not gcc.

If you cannot find the documentation for the c library reference, let me know
and I can send you a text only version of the reference manual.  Note that you
should already have this on your system.

Keep in mind we're talking *text files* here.  Editing a *text file*
in the likes of Word or Wordperfect is a pain in the ass, as these
programs are word processors.  They're meant for editing things with
lots of formatting, etc.  I wouldn't try editing my .bashrc with them.
Or this usenet post.

Personally, I can't stand vi.  But to say that using Wordperfect to
edit a simple text file is "more productive" is just plain wrong.  I
could have made my change in pico or emacs before WP has the document
open. :)

Hi!

 I want to change the number of filedescriptor on linux. I know a way to

do that:

"cat 4096 > /proc/sys/kernel/inode-max",
"cat 3072 > /proc/sys/kernel/file-max"

But it's not a good way.

Does Anybody know the right way to change the number of inode and file

What you need is to define a WINS server on the other side, and then tell
your workstation about it (in the network setup).  I'm afraid I can't tell
you if that information will be correctly passed through the masquerading
software, though.  You'll just have to try it, or wait for a better
suggestion.  I have set this up to work through regular routers, with pretty
good success.  (I found that even though I only have one WINS server, I had
to define it as both the primary and secondary before it would work).

It sounds like you may not have your hosts configured correctly.
Check these first.

/etc/host.conf

/etc/hosts

I don't use netscrape for mail but I have used Pine for direct SMTP
mail.  You can configure Pine to send mail directly while online;
perhaps, you should try this first.  Pine is pretty well-behaved and
will actually tell you what's going on if an error occurs.

Sendmail is a middleman for the mail process when it does not include
direct SMTP.  Direct SMTP means your mail client talks directly to the
server (�� la Pine).  If you want to have mail queued and sent
automatically when you go online, you want sendmail.  You also need to
do something to get mail down from your server.  Some progs will read
mail spools on remote servers, but this probably is not a good
solution.  Fetchmail is what I use.

The normal process (using sendmail) goes something like this:

client --> spool --> sendmail --> your ISP

your ISP --> fetchmail --> sendmail --> procmail --> inbox

I doubt it.  The operative word is `seem.'  I find it far more
time-consuming to have to keep moving back and forth from mouse to
keyboard to mouse to keyboard, in order to accomplish something I can
do <on> the keyboard in emacs with a few keystrokes.

I certainly get far more work done in emacs than I am able to do in
Word, Wordpad or notepad.  In fact, I finally broke down and installed
NTemacs at work, just for that reason.

True, that's why you should be using emacs.

Subject: Apache/PHP persistent variables ??
Date: Thu, 01 Apr 1999 00:09:39 GMT

When I worked in IIS/ASP, there was a variable scoping for sesson
variables and application varaiables. This allowed data to be stored
in memmory, ratherthan writing everything to cookies on each clients
machine. more important were the application scope variables, which
allowed multiple sessions to "share" a set of variables in memory.

Anyway, is there some similar type of scoping available under Apache
or PHP ? I wantto avoid excessive database reads or cookie writes, yet
I need to have data persist longer than asingle connection. I have
looked thru my books on Apache and PHP, but cannot seem to find what I
am looking for.

Any hints appreciated..

Umm.  Very carefully, then.

You might look into using GNU stow to put installed packages into
their own sandbox, generally somewhere under /usr/local.  Logging the
output of 'make install' might help, too.  But really, this is just a

I believe Power Quest's Drive Copy (or Drive Image, depending on what you
want to copy to)  will do what you are looking for.  I've had great success
using it with windows, and it claims to support Linux (although I've never
personnally tried it).  The only thing I hate is there licensing policy ($$$
for each use).  Would I pay Craftsman $7 for each screw I put their
screwdriver in?  pay per nail for my hammer?  Or maybe pay $500 for the

On top of adding value the strengthen the Linux code base by setting
things like RPM free.    The other key item that everyone overlooks is
the large amount of effort the people at RedHat, Suse and others put into
driver development.      If that does add value I don't know what does.
The simple fact is that the RedHat Cd gets a lot of people involved in
Linux that might not otherwise.    This is truely a good thing.

that they have the 'Intel-PC' type of serial cable (eg DB-9 or DB25) vs.
the 'Mac' type of serial cable (little round thingy).  It also means
that the included software (eg brand-X Fax/Dial-up/Comm) is the Windows
version as opposed to the Mac version.  For linux, you need the cable
that matches your hardware -- the 'Windows' version if you have an
Intel PC or the Mac version if you are using Linux-ppc on a Mac-ish box.
In both cases, the included software is filed in the 'round' file beside
you desk. If the software is on floppies, then you can use 'format
/dev/fd0?' on them and they then become useful for things like rescue
floppies or boot/root disks.

The most you might need to is fiddle with the init strings, but this is
just a matter of chat scripts and related config files.

Then you clearly didn't RTFM for the new kernel.  Look at
/usr/src/linux/Documentation/Changes, which lists modutils-2.1.121 as
the minimum required version.  A pointer to where to get the package
is listed in the file.

Having a broken (or outdated) insmod would definitely do this, yeah.

Why stop there? 

tar tzvf package.tar.gz 

(don't forget to use <TAB> completion on that filename)

then to unpack:

^tz^xz

to use the nifty shell replacement stuff. Or I guess you could use
Windows and not touch the keyboard at all...uhhhh...hmmm...

Hi all,

Is there any kind of RAD environment for Linux for developing GUI
applications, something like Borland C++ stuff?

How do vxWindows, V, Tk, GTK, Qt, amulet, etc. compare with each other? Which
one is the easiest to use and has the shortest learning curve?

Well I learned something.  Thou shalt not mess with libraries!

SOmehow, some of the libs in /lib got "upgraded" - they had different
file sizes and more recent dates than the CD, but the versions were the
same.  One or more of them was the culprit that was causing all the
headaches; so I tried to restore one at a time from the CD.  No such
luck; the domino theory was proven and my server crashed completely and
irrevocably this morning.  As the login was hosed, there was no way to
recover the machine without a complete reinstall (the upgrade did not
upgrade the libs).

It took 3 hours to get some semblance of the server running.  The linux
file system was rock solid, and I could copy all the config files from
the old locations so there really was very little reconstruction.  For
obvious reasons I did not trust the backups.

Q: is it common (or even uncommon) for an app to upgrade libs?  I think
all this started when I installed WindowMaker, but it was so gradual and
it did not effect samba at all until the end that I did not notice.  Is
there some way to prevent an app from upgrading the libs?

Could this have been the result of a hack?  I've found no other
evidence; and I only advance this as it seems to be the thing to blame
when admins like myself screw up.  It gives us a nice scapegoat and job
security ;-)

Thanks,

Yan
