Is the behaviour of a dynamic library similar to what VMS does when you
link
an object file to one of the RTL libraries? Which means it gets linked to
an
entry point and you can upgrade the RTL and the executable will keep
working
(provided the entry point is still there)?
A static library's behaviour is like linking with object libraries where
part of the library is copied into the resulting .exe file?
Yes, basically. Code in a static library gets embedded into the
executable at link time, whereas in a dynamic library, the dynamic
linker pulls in the contents of the .so file and resolves all of the
symbol references at run time.

Well that explains a lot. Mains power in the Netherlands costs around 23
eurocents per kWhr, that's about US$ 0.32 per kWhr (I'm not to sure what the
Euro is worth these days).
Here it is about $0.10/kWh. That is a commercial rate because I'm in
a commercial building with a three-phase feed. The residential rate in
this part of the country runs a bit higher.
Last year my house(hold) used 5400 kWhr, having two teenage daughters who
can't close a door behind them nor turn a light off doesn't help either :-)
My financee' does the same thing. :-)
Two years ago with more equipment turned on we (well my hobby :) used nearly
8000 kWh. So we're doing a lot better now. STill no reason to run heavy iron
like AS1200's or a DS20E.
They do have a nice "aura" though.
The emulated area router for area 44 is nice though! At least I can see 'my'
area in the list on hecnet.eu..
Very nice!! I am very excited about getting connected. I just need a
little more time and I'll be there.

Is electricity free where you live ???
Hardly, but I just moved to a place where it costs MUCH less than
where I used to live. Besides, the DS10L pulls almost no power, and the
VAX I'm considering running full-time is a 4000VLC, which pulls even less.
As for the rest, remember that I am constructing a museum here.
I'd love to have a couple of machines up and running, the extra mains
power
bill would be a little too much for my wallet. A DS10L isn't that bad
probably but even a VAXstation 4000-VLC adds about 20 euro's to the
monthly
power bill. Let alone running a couple of power hungry Alpha Server 1200's
and Digital Server 5305's!
My power bill here (remember this is a 14,000 square foot commercial
building) is about $275/mo. About $190 of that is my production
network, which I use for work as well as everything else.
In the summer with air conditioning, that will go up, but we're not
sure how much yet as we've just recently moved into this building.
Contrast that to what I had been paying, $700/mo in the summer,
$550/mo in the winter living in Florida, running air conditioning
24x7x265. We are MUCH happier here in Pennsylvania. (and plus there's
actual work to be found, which there isn't in Florida!)
My production network currently consists of:
Cisco 7200 VXR router
Cisco Catalyst 3548XL switch
Cisco Catalyst 3508XL switch
Sun V480 server (quad UltraSPARC III+), sixteen drives
HP DL585 VMware host (quad Opteron), four drives
Sun Netra V100 (DNS server)
80-slot SDLT tape library for backups
But also note that this network is how I make a living, maintain
communication with the outside world, and provide services for friends
and some other companies that I want to support.

I'm happy to offer a tunnel to GORVAX as well, should you want one.

Ahh ok. Do you understand the difference now? If not I can type up
an explanation of how it all works.
Are .so and .a libraries interchangeable for the linker, i.e. would this
have worked too:
NETWORK_OPT = -DUSE_NETWORK -isystem /usr/local/include
/usr/lib/libpcap.so
This is compiler-dependent, but it generally should work. The
"proper" way to link against a library, though, is to use "-l<libname>"
on the link command.

The 'crle' system is best used to completely break your system until you
figure out how to use it properly. :-D
And that it does, quite effectively!
Thankfully I did that on the test/dev E6500 and not either of the production ones. :-D
