dev-cpp-users Mailing List for Dev-C++

	Hi,

	I would like to be able to read and write to a COM port, PCI bus and
ISA bus using
	windows based C++. Is this idea possible? I have the SAMS Teach
Yourself C++ 3rd
	edition book and got the C++ CD with Bloodshed Compiler and Dev-C++
IDE. What now?

	Thanks in advance for any help, Gary.

Correction to previous post: somebody wrote (in a flawed tutorial) that =
the
API would avoid creating duplicate handles for a GDI resource. In this
instance, I was declaring several HFONT objects with CreateFont() as
dialog-scope variables, and forgetting to release them. I'm not sure =
where I
read that, or why I believed it, but it was back when I was first =
starting C
programming, and it didn't occur to me to look twice at it until today.

It was not the Win32 API that said that. I misspoke in my previous post; =
I
should read what I write before hitting that magic send button...

Happy new year all!

If I customize the make file (now that I know how to do it), under what 
circumstances will it be overwritten by the GUI?  I'm guess with a re-build 
all command.

Would I be better off if I decided to do such a thing to just roll my own 
in a different filename like Makefile to avoid this?

Thanks for your ideas.

Patrick

Hi everyone,

In case anyone else has encountered this, I thought I'd post an update: =
I
finally resolved the problem by tracking down some unreleased GDI =
resources
(FONT definitions). I made the newbie mistake of assuming that, since =
the
API says it handles such things, it really does.

Anyway, everyone have a happy New Year's.

Hi Tuukka,

Thanks for the suggestions. I've already been very careful to look at =
those
possibilities, but there is no actual processing of any kind going on, =
while
this window is displayed - all that is happening is a message pump.

Are you sore that working thread don't have memory leak problem ? This
chould be happend if pointer is incorrect and write data over own=20
reserved memory. Becose application write own memory area windows think=20
that there isin't are enything wrong and don't kill application.

The second idea is infinite loop that stop message processing.

It must be dynamically linking then. Because otherwise there is no
possible way you can get the exe that small when using the standard C++
library. That's probably a safe bet to make on Linux because you can be
reasonably sure that the GCC standard C++ libraries will be available on
any Linux distribution. You can't safely make that assumption in Windows.

Hello World in Borland's C++ compiler using the standard C++ library on
Windows produces a "hello world"  executable that is a little over 100K in
size. Mingw I think will get it down to a little over 200K after you use
strip.

Yes, I would suggest that there be a 'moderator' group of users that can
create new groups.  Otherwise the repository was pretty good, although some
of the text was too large, IMHO.  Also for some of the devpaks the download
pointed to the link location :\ (eg. the SDL devpak I believe)

Never mind; it's because I didn't include some other files on which
myfunctions.c depends. That's kind of a strange error for it to give me,
though - the error message has nothing to do with the problem!

Subject: [Dev-C++] Struct defined in external file


Hi all,
 
I'm desperate and hoping somebody here can help.
 
I have a project with a struct defined like this in myfile.h:
typedef struct { SQLINTEGER id; } mystruct;
 
In another file, myfunctions.c, I have:
#include "myfile.h"
 
void functiona(mystruct * ptrmystruct)
{
//some junk
return;
}
 
When I compile, I get errors:
[in myfunctions.c:] In file included from myfunctions.c
[in myfile.h] parse error before "SQLINTEGER"
[in myfile.h] [Warning] no semicolon at end of struct or union
 
What is this about?

This isn't really unique to Mingw32. In fact, you will hear a lot of C
fans argue that one of the reasons they don't like C++ is because the
Standard C++ library is so bloated, and does produce such large binaries.

Now the GCC compiler is not known for being the most efficient compiler in
the world, or for doing a really good job of optimizing code, and the
problem is exagerated in GCC over some other compilers. But the problem
does exist in other compilers as well.

But I think what you need to ask is does it matter? GCC is free, and it
does optimize well enough for all but the most demanding tasks. The C++
Standard Library might be bloated, but is a 400K executable really a
problem when the average computer today has 256Mb of RAM?

No, the developers of Dev-C++ will not change anything since they are
developing an IDE - an integrated environment - and not a compiler.

No, the developers of MinGW will not change anything either, since they
are "just" creating a port of the gcc compiler for use in the Win32
environment.

Maybe, but with not too large probability, the GNU project might look into
the implementation of the c++ RTL, and see if they can split in into
smaller modules to allow the linker to better strip away unused code from
the RTL.

The next thing to think about is that a binary linked with a static
library will get A LOT bigger than a binary linked with dynamic libraries.

So then C++ compiled files will be 10x bigger than C compiled ones? Man
I made a program that draws 3D objects with OpenGL and graphical
interface with GTK. It's C code and the exe is only 34KB. I'm wondering
what the file size will be if I do it in C++...

Does anyone think the developers of Dev-C++ will change it? It's very
scary.

A good C&C++ complier is ISO standard. cut & paste it and try.

A good C&C++ complier is ISO standard. cut & paste it and try.
I hope this  have help you. I heard that < cprogramming.com  >is a good

Hi all ::

Trivial defence ... I recall several months !!  Dealing with this on the =
Microsoft compiler at transition time circa. 1997 and '98.

I much prefer the "\backward" folder stuff that gcc(?) or is it a DEV =
CPP factor -- Use.

I had several project managers dumping on me for "risking' everything -- =
Mind you we delivered on time, etc, etc.  (Because we allowed for the =
'pain').

Enjoy someone's forward thinking of the compiler set-up.  It will save =
you money !

Good show folks.

Happy 2004 .... Will.

  The C++ you're using is pre-standard C++. In 1998 a C++ standard was
  finalized and became official, which altered a few things you might be =
used
  to. For instance, namespaces have been added, and are now enforced by =
most
  compilers. The standard C++ library functions, types and objects are =
now
  stored inside a namespace called "std". "void main" has never been =
standard
  C or C++, and thus has always been wrong. The newer versions of GCC =
simply
  don't accept it anymore. Furthermore, the standard C++ library header =
files
  are now extensionless, to avoid confusion with standard C library =
header
  files.
  So, applying all these changes, here is what your code should look =
like now:

  #include <iostream>
  using namespace std;

  int main()
  {
      cout << "Hello Dolly\n";
      return 0;
  }

  Hope this helped.

  Regards,


  Paul

Can you give us some examples of these error messages? What happens if you 
do an even more simple piece of code (without the iostream library) such as

int main(int argc, char** argv)
{
    int SmlNumber = 5;
    int BigNumber = 50;
    int TempNumber;

    TempNumber = SmlNumber + BigNumber;

    return TempNumber;
}

Also I do hope you are not teaching students to use depreciated styles of 
coding (the .h extention for example).

Hi Michal,

Great work. But I think there should be some limitation in creating new 
categories. First they should be general, like 3d Graphics, 
Multimediaplatfrom or Framesets. Second not everyone should be allowed 
to create new categories, maybe only a 'moderator' can create new, if 
there are in one category too much devpacks of the same kind. So far so 
_very_ good.

Maybe the project could be moved to a opensource platform like 
http://www.berlios.de/index.php.en or http://savannah.nongnu.org/. Then 
all the DevPacks could be hosted on these pages without any 
bandwidthproblems.

so long

It's a common problem: the C++ standard is changed and so your program, as
most of those learned by students, is incorrect. The actual C++ standard
library, as described in Stroustrup 3rd edition, has the following
form for an hello-world program:

#include <iostream>

int main() {
	std::cout << "Hello world!" << std::endl;
}

The old library is still present, but in a backward compatibility
directory that is not guaranteed to be supported in future.
