Re: [Dev-C++] Executable size is huge

[<age...@co...>]

This problem isn't on Linux, my .exes are around 12kb are so for a simple program that does multiplication.

Re: [Dev-C++] ANN: devpak repository

[Matthews <dem...@uw...>]

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)

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

[Ed C. <em...@ed...>]

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!

I have a project with a struct defined like this in myfile.h:

In another file, myfunctions.c, I have:

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?

Re: [Dev-C++] Executable size is huge

[Per W. <pw...@ia...>]

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.

  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()
  {

RE: [Dev-C++] re+ Public Domain C++ IDE

[Daniel G. <sp...@ho...>]

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

RE: [Dev-C++] re+ Public Domain C++ IDE

[P.D. v. Z. <pa...@my...>]

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

Re: [Dev-C++] re+ Public Domain C++ IDE

[Ferdinando F. <s2...@st...>]

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.

Re: [Dev-C++] ok, better formulation of the problem

[P.T. W. M. <pt...@ea...>]

Forget these errors.  I determined the problem I was having there were do 
to specifying
-std=gnu99.  Still when using the -S compiler option it mandates that the 
file have the .o extension which is a pain.  I'd rather have a .s file 
created so it is persistent, and now think the only way to do this is to 
manually setup a dependency and rule.

Re: [Dev-C++] Executable size is huge

[Per W. <pw...@ia...>]

It is not the compiler. It is the linker in combination with
the design of the c++ library.

If you strip the binary, it will be a bit smaller, but you will still get
a bit of extra from the RTL.

Re: [Dev-C++] Executable size is huge

[Tim S. <ti...@we...>]

Hi Kevin,

you could try strip, for example 'strip -s filename.exe'. If you think 
your executeable is still too big, you could give upx (upx.sf.net) a try.

This is not a problem, and there is no real "solution" to it.

One alternate "solution" might be to use simple C code for a Hello World 
program. That will get you a 20 KB exe :)

However, if you wish to reduce the size of your exe, use UPX.
http://upx.sf.net

The size growth for C++ is because stdc++ is linked statically into the 
exe, however when using simple C code, the exe is linked dynamically to 
Windows DLLs (like msvcrt.dll, etc.)

Hi!

If you use SH (SuperH) family, You should try to use

KPIT GNU SH ToolChain and KPIT free support

http://www.kpitgnutools.com

There are GCC 3.3.1 for SH, H8/300, H8S and quite
good, fast and FREE support.

You can download this tools for free.
It consists some examples.
