Did you install the development package for libstdc++ ( IIRC called

It's on the 2nd CD and not installed by default.

Thanks one and all for the input, I have come to the conclusion that
there is no easy way to say conclusively that a process is a thread.
I am thinking that a useful feature would be to allow the program to
guess at what are threads by using the presence of pthreads shared lib in
the /proc/#/maps.
I'll let the user know that the thread determination mechanism
is a guess and could be wrong. I'll probably leave thread recognition
turned off by default and make it settable via a resource/menu item.
Perhaps if the per process /proc values could be updated ata later
time to contain that info.

Just want to say that I plonked down the big bucks for the Code Fusion(CF)
product from Cygnus. I used it extensively to learn my way around a very very
large project. It was invaluable. I also had Visual C++ available but found
myself continually going to CF since it was faster and better at finding
symbols... It draws nice cross ref diagrams, you can navigate up/down
a call tree ... It cost a bit, but I got more than my moneys worth out
of it. I believe it's now open source as well.
It comes with a graphical debugger which I used only briefly, so can't
comment on it too much. I have also used ddd but ran into problems with it,
perhaps it was just my config...
I would say that CF is more comprehensive than Code Warrior from my experience,
i.e. using CW for about a month of PalmOS development.
I have also tried Symantec's java IDE, IBM's java IDE and a couple of others
and find CF to be the most useful for me. It's not as flashy, but the features
it does have made it great for what I was doing.
Most of my code work is still done in vi! I know it inside and out and
have used it for 20+ years! I tried emacs for a while but could not get
used to all the ctrl/meta keys so switched back to vi. If you take
the time to learn the text based interface it can be highly productive.
Especially when you know the code already. I think IDE's really come
into their own when you are visiting unknown code.
I'm still waiting for an IDE that allows me to select which ifdef's are
on/off so I can read multiplatform code without doing 8 levels of
conditional evaluations... Then there is my desire for a distributed
real time building on multiplatforms with live multiuser editing!
Anyhow, hope this helps a bit

Subject: Question about the development of Linux
Date: Fri, 10 Nov 2000 02:40:13 -0500
Reply-To: [EMAIL PROTECTED]
I am doing a software engineering research project about software
development. The development of Linux especially interests me because
its development is very different from other big software projects. I
was able to find web sites about the history of Linux, but I couldn't
find much information about how the process of development of Linux is
organized. Does anybody know where I can find such information?
The following questions espectially interests me:
Is there a group of people who are mainly responsible to organize and
manage the development of Linux?
Who incorporate the new patches and new ported program into Linux (the
whole package, instead of just the kernal, i mean)? Distributors like
Redhat make the decision or their own distribution or is there some kind
of standard of what to put in?
Is their anybody or website who keep track of all the revisions of
Linux?
Who actually release the Linux kernal? Who decide if the current version
is a prerelease or an official release?
Regards,
Jason

Which facts are those? I was talking about a general way to think of
things. It never disagreed in any place with what this license says. It
even supports it. It basically says you need to read the license. If you
are saying that the file is GNU, and the license is GNU, and the
compiler in question is GNU, and that this license applies somewhere,
then we agree. Did I miss something, other than the license quote which
was irrelevant to the process?

Just an idea: The header files required bei the C++ Standard are called
'vector' and 'iostream' (without .h). Usually there is also a .h variant
that more or less includes/links to/is related to the standard header.
Maybe Mandrake 7.1 is indeed shipping with Standard headers only.
In this case you should try #include <vector> and #include <iostream>.

Subject: Help! Linux router between two NT networks.
From: [EMAIL PROTECTED] (UM)
Date: Fri, 10 Nov 2000 12:36:05 GMT
Basically I have two networks
192.168.1.0 (255.255.255.0)
and
192.168.2.0 (255.255.255.0)
Instead of buying a Cisco Router I decided to build a linux router/gateway
to talk between these two networks. Its actually a laptop with two 3COM
PCMCIA network cards running Mandrake 7.0.*
After reading the docs I am able to ping a computer on 2.* network from the
1.* network.
However, I want the computers to be visible in Network Neighborhood ... ie.
the NT domain in 2.* should be visible in the 1.* window.
What will that take ?
Thanks!!!!

You will need to either run the nmbd half of samba on your laptop to be
the master browser for both wires or point all of the machines on one
network to an nt server on the other network to be the master browser.

Thank you Dave:
Unfortunately, I dont think configuring the Linux gateway as the master
browser is possible ... because it (and the 2.* network) is up only for a
few hours.
I could point all the 2.* machines to an nt server on the other network to
be the master browser ... how does one do that ? ie. how do you tell a
machine on the 2.* network that the master browser is machine (say)
192.168.1.1 on the other network ?
Thanks.

I have the same problem - changing the include to that directory
generated a ton of warnings, and there are no actual .h files there, so I
suspect that's a problem.
I also get about ten unresolved symbols when I try to load the driver,
including such things as __release_region, __check_region,
tasklet_hi_vec, bh_task_vec, __request_region, irq_stat, and
ioport_resource. Could this be related to the version mismatch?
I, too, am getting frustrated. I developed the driver under RedHat 6.1,
and while it worked on the customer's 6.2, it couldn't rebuild. I didn't
have 6.2, so installed 7.0, and now all hell's broken loose, version
mismatches, missing kernel symbols, and I still can't test it...
Thanks for any help.
