Re: [DEV-C++] BUG: Dev-C 4.9.20 consolprogram has only access to 1MB memory.

[staale <st...@le...>]

Ioannis and Helmut,

Out of curiosity I tried Ioannis's code in VC6++ SP4  (w2k-machine) , and
KDeveloper 2.0 (RedHat 7.2 - gcc 2.95.x ? ) and the results are:
VC6++ 936 kB
KDeveloper 8064 kB

For fun I tried it in VB and Powerbasic to:
VB6 4382 kB
PB    4309 kB

I'm still puzzeled by the big difference between the two Dev-C releases. The
only logical explenation is that it is posible to configure this somewhere.
Pleace enlighten me..:o)

Regards
Staale Flock

Re: [DEV-C++] BUG: Dev-C 4.9.20 consolprogram has only access to 1MB memory.

[staale <st...@le...>]

Hi again Ioannis and Helmut,

Your sample code (yes the application crashes, not the IDE) died (stack
overflow) at Approximately 2002 kB on (Nt4-Sp6 - Dev-C 4.9.20).

On NT4-SP6 Dev-C 4.0 I got 32250 kB before I got a stack overflow error.

The w2k machine with first Dev-C 4.0 and then 4.9.20 installed got the stack
overflow at 2002 kB.

So we could conclude that the two versions of Dev-C (or rather accompanied
compilers) handels stack allocation differently?

Staale Flock

Of course it has. E.g. all the mingw stuff is running nicely and I don't
think gcc/g++ will run with such a small stack.
Furthermore Staale only wrote a small test for locating the error.
My primary failing programm (unfortunately much bigger) doesn't
allocate big arrays on the stack.
And why does Staale's program run under 4.0 ?

Sorry for being harsh, but I have to say so.
A C++ system which limits the stack to 0.001 Gb on machines
which have 1-4 Gb nowadays is not uptodate.

It's my feeling as well, that DevC++ 4.9.x generates 16 bits
applications by default.

>

It would be better if there were a method to increase the
stack size. It can't believe it's a Win2000 problem.

I assume you mean that your code crashes, not the IDE.There is a limit
of the stack. It has nothing to do with the compiler.


Run this code to see the size of your stack:

#include <iostream>

void stack()
{
  using namespace std;
  
  static unsigned long counter=0;

  char buffer[1024-sizeof(unsigned long)-1];
  
  counter++;

  cout<<"Allocated approximately "<<counter<<" KB of stack before i
die\n";
  
  stack();
}  
  


int main()
{
  stack();
}  


That's why for large arrays & objects we use the free store (new,
delete) or better the standard library containers such as vector.

Hi Ioannis,

As I'm not a seasoned C++ programer I welcom your your work on my code, and
your efforts in this mailing list.:o)

To be shure I test again and with som simpler code and it still fails on a
NT4-Sp6 (and w2k) with Dev-C 4.9.20 (Clean new installation of the computer,
also the OS!!)

I't works on a NT4-Sp6 with Dev-C 4.0

See also the 'tread'
    [Dev-C++] not enough memory - how to configure Win2000

RE: [Dev-C++] Dev-C++ 5 Beta 2 / Win98

[Ioannis V. <no...@ho...>]

I know it is a religious issue, but what do you think of the idea to
write Dev-C++ in C++? I guess more people would help to its development
(also check Kernighan's text "why i do not like pascal").

How i would do it in your case:


#include <iostream>
#include <cstdlib>
#include <vector>


int main()
{
  using namespace std;
  
  const unsigned long MEGA_BYTE = 1024*1024;

  long nMBSize;

  do
  {
    cout << "\nGive MB size: ";
    cin >> nMBSize;

    vector<char> narrBig(nMBSize*MEGA_BYTE);

    cout << "Array contents size: " << narrBig.size()<< " Bytes." <<
endl;
   
    for (unsigned long i = 0; i<nMBSize*MEGA_BYTE;i++)
       narrBig[i] = 'A';

    cout << "Array contents size: " << narrBig.size()<< " Bytes." <<
endl;

    // vector is destroyed at the end of its scope, and its contents are
cleared

[DEV-C++] BUG: Dev-C 4.9.20 consolprogram has only access to 1MB memory.

[staale <st...@le...>]

Se also thread:
    [Dev-C++] not enough memory - how to configure Win2000
on the mailing list. Test code below

Hi Helmuth,

Turns out this has somthing to do with Dev-C 4.9.20.

This is what I did to verify the problem:
1: Tried your file on both w2k (Clean system) or NT4-Sp6. It failed on both
machins.

2: I installed DEV-C 4.9.20 (downloaded today) on a clean w2k machine and
encountered the same problem when I compiled and ran the code.

3: Tried to uninstall DEV-C 4.9.20. Uninstal DOES NOT work. Delete the fiels
manualy. Search for dev-c in regedit.exe and then run RegClean.exe just
search for RegClean and you should be well of (Might not nead this see pkt
5)

4: Installed DEV-C 4.0 on the w2k machine  Compiled and tested OK to 31MB.

5: Installed Dev-c 4.9.20 on top of the 4.0 and It still worked nicely..:o)

6: Installed Dev-C 4.9.20 on NT4-SP6 (Only Winzip appart from OS). Added
shlwapi.dll and wininet.dll to system32 folder. Tried to run the code but
no. Same failure.

7: Installed Dev-C 4.0 on top of the 4.9.20. This did not help. Brobably
because both installers does not overwrite existing header files (?). So you
should delete the 4.9.x installaation. Install 4.0 and then 4.9.x (if you
nead it. It is a must if you want to use the wxWindows lib, if I understand
right)


I'm not a seasoned C developer but would gues there are somthing wrong with
a header file or reference making dev-c 4.9.x compile to 16bit code(???)

I don't know about version 4, but WxWindows works correctly with the

I will release a WxWindows package when Dev-C++ beta 3 is released.

Hi:

I have a project that I have been developing using Dev-C++ 4 and

version 5 Beta 2, adding the lines in Project Options that were not 
picked up by the new version, and I get "windres.exe can not find

 throws 'no file or directory' even when I copy that library to the

I wouldn't like to use the Cygwin installer because it might conflict wit=
h=20
W32/Debian packages. Let me explain again what I would like to contribute=
 :

1) Package management

- Port Debian dpkg to native Windows and compile it using mingw. This tas=
k has=20
nearly been accomplished on http://debian-cygwin.sourceforge.net/bootstra=
p/.

dpkg is a very powerfull package system comparable to RPM on Linux. I don=
't=20
know if it is possible to compile dpkg natively under Windows using mingw=
=2E

- Create W32/Debian packages providing mingw core packages.

- Compile Cygwin.dll using mingw. This will enable the creation of a firs=
t=20
W32/Debian Cygwin.dll package. This should be possible using MSYS-1.0.7 a=
nd=20
MinGW-1.1.

This will allow to create W32/Debian packages and tell wether they depend=
 on=20
Cygwin or not. For example, we may offer Perl with depency to Cygwin and=20
another one with no depency (mingw).

- Create W32/Debian packages providing Cygwin core packages.

- Create a bunch of packages (Xfree / qt2 / KDE2 / Gnome). Porting has al=
ready=20
been accomplised on Cygwin. Even KDE3 is on the way.

- Create packages for Windows only software like Dev-C++. Nearly all GNU=20
Windows native programs should be included.

2) GUI installer

W32/Debian installation should be performed within a single GUI. The=20
installation program will give access to all W32/Debian packages at once.=
=20
Packages will be available on Debian mirrors.

As Cygwin and mingw can co-exist, I think this project could well be achi=
eved.=20
Any candidate? Help welcome.

Why don't you just use the binaries? Win32 binaries run on every Windows 
system,
so there's not much point in compiling them yourself.

Re: [Dev-C++] not enough memory - how to configure Win2000

[staale <st...@le...>]

I have tried my sample program on a w2k machine now and it work al the way
up to 31 (thats wher you meet the long border is it not)?

If you send me your compiled binary, I'll giv it a try. (hmm, could be
during thge weekend as I'm sceduled for the next 48 houers.:o) Also if you
search for the drwtsn32.log file. Giv it a new name, delete it or what ever.
Run the test program again. And then include the drwtsn32.log file in your
mail to me. I might be able to help a litle bit more. The drwtsn32.log is a
simpel debug dump file (I think www.sysinternals.com has an articel on how
to read it).

A thought, how do you start the program? From the Dev-C IDE or in a console
window? If you use start-run-command.exe I belive you will be runing a nativ
DOS session. You should use start-run-cmd.exe (don't nead the exe part) to
get flat memmory. The last is what you get if you double click the
pBigArray.exe from explorer.

On the side line (this is not a windows 2000 feature):
I think XP has a 'feature' where it anticcipates which OS it should run the
program under. In your case it seams like it is running like a nativ dos
(win95) program. I have no experience with XP my self so don't take my word
for it.:o) I know that it is posible to turn the 'feature' off for
particular programs. I think you rightclick the program and then select
configuration from the pop-up menu. I wold assume you will have to do the
same with all the programs in the bin folder of Dev-C to.

Yes, I see. There is one possibility:
using pointers, isn't it?.
The solution seems similar to the case
of self-referenced structures:
when you build a linked list or a binary tree
you need a solution like that.

[Ioannis V. <no...@ho...>]

Yes, that's rational. I explained why 2 classes can't have objects of
one another both at the same time (1 object occupies at least one byte
even if it belongs to an empty class:
=20
class emtpy{};
=20
).
=20
 So it was a situation with an infinite number of objects (and memory)
so it correctly doesn't compile. The situation you describe is ok.

the computers would crash. :)


Imagine the code:

class B;

class A
{
  B b;

};

class B
{
  A a;
};


A contains a B which contains an A which contains a B...


That's why it can't be done.

[Shaddow <sh...@ti...>]

I didn't see the original question so I may be answering something that 
hasn't actually been asked.  If so, just ignore what I have to say.

While it's true that you'd get yourself into all kinds of trouble trying 
to have A be a data member of B and B a data member of A, it is entirely 
possible (and actually at times necessary) to have B* be a data member 
of A and A* be a data member of B.  You see this kind of a situation 
frequently in frameworks.

class B;

class A
{
  B* b;
};

class B
{
  A* a;
};

I suppose the question was for me and i suppose the question is to have
2 classes one containing an object of the other (i did not pay much
attention when i saw the code).


Well this cannot be done and it is good it can't be done, because then
the computers would crash. :)


Imagine the code:

class B;

class A
{
  B b;

};

class B
{
  A a;
};


A contains a B which contains an A which contains a B...

Re: [Dev-C++] not enough memory - how to configure Win2000

[staale <st...@le...>]

Try the code below. I have allocated 30MB  successfully on NT4 with SP6. Are
you running NT or a win9x OS? They allocate memmory diffrently. (I'm no
expert in how, just know they do..:o))

If you are running NT4, w2k (or XP) you get the task manager with
Ctrl+Shift+Esc. There you can see how much memmory the program does use
(hmm, sort of...)

Why does Outlook insert file: infront of all //. Sorry but you have to
remove that by hand (Courtesy to M$)..

I think you shuld do some debugging. Install the Insight5_win32 debugger and
you should be well off.

------------ code snip -----------
#include <iostream>
file://#include <stdio.h>
file://#include <stdlib.h> file://usedt by system("PAUSE")

int main(int argc, char *argv[])
{
const long MEGA_BYTE = 1024*1024;
long nMBSize = 1;
while (nMBSize != 0 ){
   cout << "Give MB size: ";
   cin >> nMBSize;
   char narrBig[nMBSize * MEGA_BYTE];
   cout << "char size: " << sizeof(char) << " Bytes." <<  endl;
   cout << "Array size: " << sizeof(narrBig)<< " Bytes." << endl;
   file://See if initializing each element makes a difference
   for (unsigned long i = 0; i<nMBSize*MEGA_BYTE;i++){
      narrBig[i] = 'A';
   }//i
   cout << "Array size: " << sizeof(narrBig) << endl;
   file://If you store objects in the array remember to use:
   delete []narrBig;
}//while (nMB..
file://To have a breake before window closes, use:
file://system("PAUSE");
  return 0;
}

RE: [Dev-C++] Foward declaration

[Ioannis V. <no...@ho...>]

ANSI C++ forbids the definition of an object before its type is defined.
It's not a compiler problem.
