This is already in the FAQ. But everybody can reach this mailing list 
without reading the FAQ. I suggested some time ago that this mailing 
list's address should be hidden *inside* the FAQ; so nobody could ask 
anything here before reading it.

somebody shoot me.

can the web developers put this as a FAQ or in big red writing on the

Hi All, 

I just downloaded the latest Bloodshed IDE for C++ and
tried out a Hello World Program with a cout <<"Hello..
.";
When I tried to runt the program, the DOS window just
flashed once and disappeared. How can I look at the
output of my program? I tried looking the settings but
in vain.

Any help is appreciated,
Thanks,
Kiran

Since I use a text-only mail reader, I assumed the image was a screen-shot
of some problem. Obviously not :)

Besides the RTFM, it is always a good idea to supply some source + error
messages when something isn't working as expected. Since we don't have the
slightest idea about the problem, there really isn't much solutions we can
help with.

Hi.

Have exactly the same problem with Dev-Cpp. Did you ever find a solution? I'm
suspecting that the compiler does not support these #pragma settings. I've
Googled around for days to find a solution, and even Microsoft says it should
work (maybe they inplicitely mean: Works with VC++)

Omfg. Yeah. This is amusing. RTFM!

I can't get my program to open text files. I am extremely new and am 
using the projects that come with DEV as a base, any tips?

One more thing. If g_pIrcServerDataBase->currentNetwork() returns NULL,
you will never assign any value to your m_pSrv member within the
beConsole() constructor.

Wait a minute.

m_pSrv is a pointer pointing to an object.

KviIrcServer* beConsole::server()

should return a pointer, i.e. the contents of m_pSrv, i.e.
  return m_pSrv;
and not a copy of an object as is done by
  return *m_pSrv;

When a function returns a pointer, this of course doesn't mean that it
returns the address of the pointer, but the value stored in the pointer,
i.e. the address of an object.

Are you sure that the beChannel object really have a valid pointer to your
beMDIWindow object.

Also, note that qDebug() which I don't know what it does might be
dangerous in case you have a multi-threaded application. Only the thread
that owns the MDI window should try and used any GDI objects.

It's tricky but I think I got it

In fact I am returning a pointer to m_pSrv which is a pointer itself, rathe=
r=20
than the adress of the class, right ?

What could have worked is if m_pSrv was the class and that I returned &m_pS=
rv,=20
the adress of the class.

But I've done like this :
KviIrcServer beConsole::server()
{
	qDebug("returning server");
	return *m_pSrv;
}

Thanks for help !

Hi Black Eagle,
 
It could be that you are returning the address of m_pSrv rather than it's contents.  You've declared m_pSrv as a pointer to a KviIrcServer class.  However, in server(), you return m_pSrv, rather than it's contents *m_pSrv.  server() is declared as returning a pointer to the class, which is the value of m_pSrv, not it's address.
 
Hope that makes sense!

The error is in the function KviIrcServer* server() at line : return m_pSrv;

In all other functions I got no problem with this variable. It is another

Thanks for any help !

Hi Mohamad,
 
Just use Google for 'tutorial c++ x', where x is autoconf, automake, etc.  You should be able to find what you want on-line.

The problem is that it isn't enough to add an include file to your source.
You must also add the corresponding library file (libXX.a) to the project.
Specify -libXX in the linker options.

Hi all,
I'm new to g++. I'm trying to use a new library for linear algebra=20
called Lapack++, the problem is when I include this library into a=20
source file I get errors of kinds "undefined refernce". for example this=20
little and stupid code:
#define LA_COMPLEX_SUPPORT
#include <lapack++.h> // the new library
#include <iostream>
int main()
{
   LaGenMatDouble A ; // this uses the new library=20
   std::cout<< "This is a test  "<< std::endl;
   return 0;
}
the erros are like:
/tmp/cc2YU0wo.o(.text+0x19): In function `main':
undefined reference to =AB LaGenMatDouble::LaGenMatDouble[in-charge]()=BB

What could be the problem?
Please give me some feddback.
thanks in advance

Dear Users,

   Does anybody know where can I find a C code that does a .wav to
.txt file conversion?
   I=B4m not talking about speech to text conversion, ok?
   I am looking for a C code that pick a .wav audio file and makes
a "translation" to a time vector (a music(n) vector). This vector,
for example, can be loaded in Excel or MathLab to plot a figure, ok?

Regards
Andre

You use the way that is defined in the C++ standard:

asm(" ........ ");

So you would do:
---
asm(
    "movb $0x20, %ah \n"
    "movb %ah, %bl \n"
    "incb %bl \n"
    "addb %bl, %ah \n"
);
---

Remember, GCC uses AT&T syntax by default. If you want to work with 
Intel syntax use the "-masm" option:

|-masm=|dialect||
    Output asm instructions using selected dialect. Supported choices 
are |intel| or |att| (the default one).

Thanks! Everything works now and is happy....and so am I. :)

Dear Dec-C++ user,
I have problem with using "asm" statement.
Please tell me the correct syntax of this statement.
For example how can I use the following assembly codes in my C++ programs=
?

mov ah,20h
mov bl,ah
inc bl
add ah,bl

Thanks,

HI Issac,
 
You should add the SQLite files to the project, then go into the Project Options -> Compiler window and select compile as C for the SQLite sources.  You have to do that to each file individually.

I've got a C++ project that requires a public domain C library (SQLite). I am trying to compile the library directly into the project, instead of linking to the library. I've tried compiling SQLite as a C++ project, but it generates tons of errors, so it really does need to be C compiled. Anyway, is there a way to add those files to my project, but have the C compiler invoked on them, and the C++ compiler invoked on the rest? Does that make sense? Thanks!

Hi,
	
I'm trying to debug a program which I know produces a segfault at a certain 
point. I've set a number of breakpoints by clicking on the black band at the 
left of the editor window. When I click the purple checkmark icon to initiate 
debugging, there seems to be no visual clue as to current location in the 
program. If I click "run to cursor" several times, I get the expected segfault, 
but I never know where I am in the program, and clicking "Step Into" or "Next 
Step" seems to have no effect.

I've compiled the program with all optimizations disabled and with the -g option.

Any help would be greatly appreciated.

Best Regards,
Jonathan Turkanis
