O.K.
This is the first step of a project I am starting so any help is
appreciated!
Has anyone got PPTP (PopTop) working with SuSEfirewall2? I have
everything working without the firewall and when I enable the firewall I
can login but I can't ping the system behind the firewall. Any ideas? I
have each working but not together.
Thanks!

Hi All
I'm trying to start Linux programming but keep coming up against problems. The
latest one is OpenGL programming with a Geforce 3 graphics card. I'm told
that I have to use the NVidia OpenGL libraries (nvsdk) but having downloaded
it, it seems to be totally Windows. I have no idea how to use it (if it can
be used under Linux) and even the docs are in Windows formats. Can anyone
help me on this or do I have to throw this otherwise good card away and start
again?
TIA

Hi,
I'd like to ask a (basic) question about operator post inc (lvalue++).
I've this code fragment:
/**************/
int y = 10;
int z;
z = y++;
cout << "z = " << z << '\n';
int x = 10;
x = x++;
cout << "x = " << x << '\n';
/**************/
The execution results in:
z = 10
x = 11
I'm confused why x became 11, because the post inc. operator has
higher precedence than assignment, so given an expressoin x = x++,
x++ is evaluated first. The signature for post inc. is T operator++(int).
So the return value of x++ is 10 (x itself will be modified to 11), but
then the expression of x = (x++) become x = ret_val_of_x_plus_plus,
which is x = 10? Am I correct?
Regards,
Verdi

This is probably best asked on the suse-programming-e list. The problem
files are qtableview.h and ktmainwindow.h. These are probably expecting
the qt and kde library include files (QT and KDE devel RPMs).
I think qtableview.h is part of QT 2.3.2 but not QT 3.0, which might be
part of the problem.
It should not matter where you compile a package.

Good morning Jesse,
Thank you very much your assistance.
You are right. It works now.

The flwg to be noted:
without option "-g" in "g++ -g -o filename filename.cpp", in contrast to the
things I experienced under Suse 7.2, debugging does no longer work now. The
same error msg "init.c: No such file or directory." is produced.

I've just installd SusE 8.0 on my home computer.
I've installed Octave and Kpl and Kmathplot.
I'm a Physics graduate student eager to grab as much scintific s/w
packages as I can!
I'm paricularly interested in any other s/w package that deals with
O.D.Es and P.D.Es and BioChemistry that is available with SuSE 8.0 from
the distribution kit or from the web.
How many of this s/w packages can be installed and run on Red Hat ???
Thank you in advance for your attention.

Jesse,
Thanks for your advices.

I have installed ncurses-devel. Then I did the flwg:
- ./configure
- make
- make install
- make distclean
gdb 5.2 has been installed.
But the "list" function still does not work well, with the same error
messages "init.c: No such file or directory."

Hi Jesse & John,
I am using gdb version 5.1.1. Following your tips, I just tried to install
gdb 5.2.
Now I am facing an installation problem. The last few lines after typing
./configure show flwg messages:
checking compiler warning flags... -Wimplicit -Wreturn-type -Wcomment
-Wtrigraphs -Wformat -Wparentheses -Wpointer-arith -Wuninitialized
checking for cygwin... no
checking for tgetent in -lncurses... (cached) no
checking for tgetent in -lHcurses... no
checking for tgetent in -ltermlib... no
checking for tgetent in -ltermcap... (cached) no
checking for tgetent in -lcurses... (cached) no
checking for tgetent in -lterminfo... no
configure: error: Could not find a term library
Then 'make'-command does have any effect. So the installation failed.
gcc I am using is that of version 2.95.3. The newer version gcc 3.0 has been
installed as well, and is occasionally used.
regards,

On SuSE 8.0, when I use emacs editor to view an MSDOS file, I see the funny ^M
characters at the end.
On the usenet, people suggest searching-replacing ^M, but I don't like this
solution. XEmacs is OK and its MULE environment correctly recognizes and
converts the ^M.
Has anyone gotten emacs to work with DOS files? I don't like XEmacs.

Salman,
I don't know how to do what you want either, but it almost sounds like you are trying to write a shared memory application.
If so, shared memory is definitely the way to go, and standard across most varieties of UNIX.
Of course, shared memory requires both programs have code to handle it, so you may not have that flexibility.
