Not that you mentioned it directly, but in case you are also thinking of
Common Lisp, you need to think again.
While Common Lisp environments tend to be interactive, there is absolutely
no reason why they should also be interpreted. It is perfectly feasible
for a complete, interactive Common Lisp environment to contain _zero_
interpreters. In fact, at least two implementations are on the market
that operate strictly on the principle of "compile->execute".
Now, back to C++:
There is one thing I've been meaning to ask the C++ crowd, and now I'm taking
the opportunity to actually put the question:
Does C++ contain closures independently of the OO things ?
(Not that an answer in the affirmative would make me use C++, it is all idle
curiosity...)

Subject: KDE apps compiling
I'm having a problem compiling KDE apps:
I have g++, the KDE and QT libs all installed properly (as far as I can
see), but I get an error when trying to configure the makefile (using
the provided 'configure' program). The error message is something like
"Couldn't link a small KDE application!". The same machine can
successfully compile and link GNOME apps written in C++. This happens
with every KDE application that I have downloaded and tried to compile.
Is there berhaps some common KDE developers step that I have missed when
installing my machine. (Which is RH6.1 btw, with the supplied KDE, QT
and egcs development packages installed)
Thanks

One of the biggest problems I've got with Java is the lack of a standard
aside from not being a language useful for the kind of problems
I have to tackle.
Up to now Sun's policy regarding Java might be described as, well, the
biggest mess since the Big Bang. Sun just cannot make up its mind and
to me Sun does not have any interest in Java at all but Sun's priorities
seem to be ...
( I) - how can Sun profit from people using Java
( II) - how can Sun profit from people using Java
(III) - how can Sun profit from people using Java
... but this is just something my nose keeps telling me, although my nose
rarely betrayed me in the past. It never did, that is.
Yes, it is a very nice nose, I like it too.
Another personal opinion is that current Java developers should put
more pressure on Sun to get things sorted out, as without them Java
would be nothing but another four letter word.
Up to then, try Ada,
Juergen

There's some documentation with the package. Also, see the FAQ:

And Kurt Wall's <Linux Programming by Example> has two chapters on
ncurses. Not too bad.

Anyone know how to get cvs to use ONLY ssl to talk over the i-net. I
have tried compiling in Kerberos and GSSAPI support but this is proving
to be a complicated nightmare. I know you can forward ports with ssh
but the thing always forces you to enter a passwd to set up the port
forwarding. I want to be able to run cvs securely over the internet but
without having to enter a password everytime I want to start the
server. TIA - Greg

Hi!
Could someone please suggest me a simple way of programming in pascal
under linux? I just want to use tty mode. I'm looking for something very
similar to turbo/borland pascal. I am currently using delphi in console
mode under vmware/win98 because I need more memory than I can get in DOS,
but it's not very convenient. Is there an API under linux similar to turbo
pascal?
Please, email me, too, if you reply.

Hi all,
my application uses serial port to receive date on 56700 bps.
Application do something that's on each received amount of data.
Default size odf tty input buffer is 4096 bytes. How to resize it
on 10k ?
My second questions is: Is it possible to register tty discipline from
userspace ?
And my thirth question is: How to receive "message" from kernel TTY_OVERRUN
when overrun of serial port occures ?
Thanks for any answer to my email

Hi!
I'm writing a client/server socket (tcp)
application in c. It works fine when I run it on
the local machine. I start the server by inetd.
When I try to connect from another machine on the
same net the connect() call fails. I can use
telnet to connect to the serverapplication on the
port I'm using, but connect() in my own client
application fails.
Does anyone have any ideas what I might have
overlooked? I asume that there are no problems at
the server end since I can telnet to it.

Subject: Help on packet scheduling ,dev->tbusy

Reply-To: [EMAIL PROTECTED]
Dear all:
my packet scheduling strategy is to write a function that instead of
hard_start_xmit function pointer in
device driver,
and in my function I enqueue the "skb" packet buffer and run some
packet scheduling algorithm,
(not use linux TC)but when to call the dequeue function ? to restore the
original hard_start_xmit function and transmit?
Linux TC(traffic control) calls dequeue after enqueue, and use the
dev->tbusy as congestion control,
that means,in a bottleneck the times to call enqueue will greater than
dequeue,so there will be more than
one packet in the queue to be scheduled, but when I use plip0 at one
side in the gateway as a bottleneck,
and the dev->tbusy is always not busy,so every time the packet just
dequeued after enqueueing.
I also find the gateway receive about 10,000 packet in eth0 side,but
only transmit 2000 packet at
the plip0 side, kernel has dropped the packets, can you tell me why and
at which point?
even the traffic generate from the gateway(not from eth0 side) get the
same result. to,
can you help me?

Thanks for the pointers. I've implemented a class to handle

Summary : Free Pascal Compiler
Description :
The Free Pascal Compiler is a Turbo Pascal 7.0 and Delphi compatible 32bit
Pascal Compiler. It comes with fully TP 7.0 compatible run-time library.
Some extensions are added to the language, like function overloading. Shared
libraries can be linked and created. Basic Delphi support is already
implemented (classes,exceptions,ansistrings).
This package contains commandline compiler and utils. Provided units are
the runtime library (RTL), free component library (FCL), gtk,ncurses,zlib,
mysql,postgres,ibase bindings.
URL : http://agnes.dida.physik.uni-essen.de/~gnu-pascal/
Summary : GNU Pascal
Description :
A Pascal compiler based on the GCC 2.8.1 compiler.
GNU Pascal is part of the GNU compiler family, GNU CC or GCC.
It combines a Pascal front-end with the proven GNU C back-end
for code generation and optimization.
Name : p2c
Summary : A Pascal to C translator.
Description :
P2c is a system for translating Pascal programs into the C language.
P2c accepts input source files in certain Pascal dialects: HP
Pascal, Turbo/UCSD Pascal, DEC VAX Pascal, Oregon Software Pascal/2,
Macintosh Programmer's Workshop Pascal and Sun/Berkeley Pascal. P2c
outputs a set of .c and .h files which make up a C program equivalent
to the original Pascal program. The C program can then be compiled
using a standard C compiler, such as gcc.
Install the p2c package if you need a program for translating Pascal
code into C code.
There are also Modula and Oberon implementations available.
