dev-cpp-users Mailing List for Dev-C++ (Page 14)

Thanks all.  I figure memory is memory, but I'll try allocating the 
space with malloc.
 From some of the noise I've read on the web, I thought there was 
some adjustment
that could be made to some configuration item, that would allow 
larger size arrays to
be declared with minGW.

Two megs? Or  "char somvar[2,000,000]"?

If the latter...then that is way more than you'll probably need. That's a
very large array. Now, if you can only allocate two mB, then something is
wrong with the compiler, OS or with your code. Try allocating it with malloc
instead of using a standard array.

John,

For that kind of a size I'd suggest using dynamic memory instead, the new 
operator if you're working with C++ or the calloc function if you're using C 
since it's an array that we're talking about. Pushing that much data 
directly on the stack seems unwise.

Kind regards,

Philip Bennefall

Are you having problems in FreeBSD? Is there even a kern.maxdsize for
MinGW?

Are you talking about global arrays, or local on the stack, or dynamically
allocated? Uninitialized or initialized arrays?

I've searched all day, but I can't find any help for increasing the
size for declaring arrays.  I can use a little over 2 meg.  I saw
one suggestion about increasing the minGW "kern.maxdsize",
but I can find no info on the web about how to do that. Anybody
have any suggestions?  p.s. I'm using Dev C++ version 4.9.9.2

Buanas tardes,
Cuando trato de compilar me aparece el siguiente error 
  invalid BFD target  `dynamic'   , y no se genera el .exe, al parecer es un error en el link, por favor necesito ayuda pues he intentado varias cosas y ninguna funciona y en google aparece muy poca documentación al respecto.
saludos
merlin



      

Estaría muy agradecido si me ayudaran con lo siguiente: cuan do intento compilar un programa me sale esto:
 
BFD target `dynamic'
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 1 seconds)
0 errors, 0 warnings
 
saludos
merlin


      

Are you aware that all development of Dev-C++ has been down for a number
of years now?

May I recommend that you take a closer look at the Code::Blocks IDE
instead? It is a full-featured environment that supports multiple
configured tool chains making it easy for you to use cross-compilers for
some projects, and native compilers for other projects.

It also has better debugger integration, when used with the MinGW compiler
to build native applications.

Hello

I'm using 4.9.9.2 on Windows 7 with gcc m68k cross compilation tools. 
DevC++ is excellent for the task and the beta version has pretty much 
worked flawlessly. Thanks and kudos to the team - we will be making a 
donation.

One issue that arises is the DevC++ configuration. If I open a .dev 
project file from the Explorer context menu, the IDE uses the config 
data stored in (for example) 
..\Users\Username\AppData\Roaming\Dev-Cpp\devcpp.ini. In my case this 
does *not* contain the right cross-compiler config, which is contained 
in a subdirectory of the devcpp installation. Is there a better way to 
do this?

Also the initial config wizard has no option to escape/cancel, which is 
annoying when you *have* configured things.

So how about writing a single registry entry to locate the config file? 
If no entry or specified config file absent then give the user the 
option to either proceed with configuration or locate an existing config 
file. There is already a DevCpp registry entry here:

HKEY_LOCAL_MACHINE\SOFTWARE\Dev-C++

I'd submit patches myself but guess what ...

Thanks again.

Jerry.

C and C++ are just two programming languages. They can be used for almost
anything.

When doing things in Windows, you should take a look at the Microsoft MSDN
site. It contains the documentation for all Windows-related API. These API
will let you do just about anything you have seen any Windows program do.

Have you remembered that C++ have added namespaces? Did you write
std::cout and std::endl or try the "using" keyword?

Hi,
how can I read one by one line  from a file?
The matrix is double but should I compare what I am reading with '\r' or '\n', how if
they're different types?
I've tried fread but I have to define how many bytes I'm going to
read (isn't it?) but the size 
of the matrix is dinamicaly allocated.
Tks in advance for any help.

Hey guys I'm new to c++ and when I tried to write my program, I get the errors that cout and endl are undeclared(use this function first) any suggestions?
Sent from my BlackBerry Smartphone provided by Alltel

hello,  I am making an exe file of an opengl program to execute from a
normal C program.

  int result;
  result = system(path of the exe file);

  The program works fine and the exe file of the opengl program opens when i
execute this program. But when the graphics part start in the opengl
application, there is an execution failure.
 I found that, this problem is mostly due to insufficient runtime memory
provided to the program, which must be high for these programs.

 Can anyone help me solve this issue when I use dev c++.

thanks in advance

The most important things to think about:
- use a good algorithm.
- turn on optimization.
- get experience.
