dev-cpp-users Mailing List for Dev-C++ (Page 22)

In C++ the only difference between a struct and a class is that in a
class the default access is private whereas in a struct it is public.
in all other aspects they are the same.

Dear users,

   When we need to develop a OO app, one way is to create
classes, with attributes and methods. After this we instanciate
the class in our program, as it is, or with some specialization.

   Thinking only about ANSI-C, we can create structs with the
usual fields (attributes), but we can associate functions inside
the struct too. After this operation, putting this struct definition
in a .h file, we can make a variable declaration defining it as
a struct type (the one created in the .h file).

   In this scenario, disconsidering the protected/public/private
features, please talk to me abou what a OO app can
do that a struct like .c program can´t.

Regards
Andre

Hi there is a pthread for windows: http://sourceware.org/pthreads-win32/

About the socket, there is a socket library for windows too. Check this

Hello list

I have a library developed in C++ with GNU C++ (Linux) and want to port it to Windows. In the earlier versions tried using Visual C++ and was a bit difficult to maintain since some OS and hardware dependent functions were quite different or unavailable.

In particular I had to modify my threads and sockets code for windows and create some kind of simple MUTEX_LOCK for multithreading, so aparently for the programmer it was enough to call the library functions in the same way under Linux and Windows, but was hard to maintain both versions so the windows version was deprecated and continued working on the *NIX version only.

Recently I found dev-c++ and that it is based on the GNU C++ compiler and it atracted my attention again, most of my code works 100% without changes except the threads and sockets code that has no available functions in the included libraries.

My question is if it is possible in some way to integrate *NIX socket support (socket, inet_addr, gethostbyname, etc) with dev-c++ and it would be nice to have some kind of pthreads support maybe by adding an extra module or library.

Any coment or help on this?


Thanks,
Miguel

   Hello everyone,
 
   I, once again, need your help :D    This time, my question is related with the GCC...    Well, I am in the process of writting a simple freestanding application, and I wish to have access to a small part of the C library, to be used with a hosted application.   I have found, by googling, that I can either write myself the subset I require, or port a free one, already existing.   To save time I have decided to port a existing one, however before I start doing so, the design of the API has to be decided... This left me with some questions...         Ex : With the GCC, how can I define a target? I can compile PE, COFF, ELF .... how can I compile "insert_my_format_here" ?      Is there a way to define my target, and compile it?      Please advice.            
 
 
Frederico Marques

Hello ppl,

I have just upgraded Dev-c++ to version 4.9.9.2...But i have a problem

Iam not able to convert an int to char in a stack of type char...

   stack<char> s;

    int dData;

    while(dData!=13)
    {
      dData = getche();

      if(dData==8)
         s.pop(char(dData));

      else
          s.push(char(dData));

    }
However this was working fine in Dev-c++ version 4...but does not work in
dev-c++ version 4.9.9.2
I get the error: "no matching function for call to 'stack<char>::pop(char)'
"

PLiz help guys...
Cheers...

There are two separate installations of Dev-C++.

One with just the IDE - i.e. the editor.

And another installation that contains both the IDE and the MinGW
compiler. Have you selected the full installation file, so you have any
compiler to use?

Good morning,

Have Dev-C++ 4.9.9.2 and it works fine.

Installed on it the Allegro 4.2.2 graphic library.

Doesn't compile or links even the demo programs (C:\Dev-Cpp\allegro\demo).

Guess has something to do with "Add the following commands when calling compiler" and/or "Add these commands to the linker command line".

Would like to hear the advice from someone who actually succeeded making an exe from Allegro and Dev-C++.

Best,

Geraldo

First of all, the question is if MinGW can be used to write an Excel
plugin. Dev-C++ is just an IDE. MinGW is the compiler.

But a more important question is what you want to solve, and why you think
a plugin written using MinGW is the way to reach your goal.

Is it possible to make an Excel add-on with Dev-C++?
If so, a link to an example would be helpful.

Thanks,  John

Don't know if that is possible to correct with the SourceForge system.

It could have been worse. A couple of years ago, a Spanish ISP decided to
send out auto-responses for any list mail, with the request that the list
- and all posters to the list - had to register with their mail service to
not be considered spam.

They could not understand why I called their mails spam...

Hello,

I have just subscribed to your mailing list. When I try to compile a code
with the last version of dev cpp it shows me an error message:

Dev-C++ - [Build *Error*] [*main.o*] *Error* 1

The system cannot find the path specified.

MinGW documentation can be reached from:

Compiler and library manuals:

But if you are looking for specific documentation, then you really have to
be more specific in your request.

You ask the question "Does this problem need the "C++ feature" to solve or
could just be done with C or C/C++ hybrid?" and get angry that people
on the list doesn't answers the question.

Of course you can count symbols using C or using C++ objects or anything
in between. The original problem is trivial and most batch script
languages can even be used to solve it.

But only the original poster can possibly know exactly what language
choices his professor expects to receive the solution in.

Or are you saying that you "Eric" is the same person as "Fernando
Lichtschein"?

If you want to find faults with this list, you should instead note that
Dev-C++ is a dead product, and that most people are using Code::Blocks or
similar instead. Compare number of posts on this list now, and maybe
five-six years ago.

Last month had 18 posts. September 2002 had 362 posts. All-time high was
597 posts in October 2002. People with interesting questions normally ask
them on other forums/lists, while a large percentage of the remaining
posts to this forum really do represent attempts to cheat on school work
with the same question dropped off to a large number of forums/lists just
to find someone who is ready (stuid enough) to give a "turn-key" answer.

With 15 pots/day, it is meaningful to spend the time to write good and
complete answers since there will be many who may read the answer. With
one post/day, the incentive to spend the time has dropped quite a lot.

The simplest questions to this list is normally school work that shouldn't
really be answered... The last one was just days ago by someone who didn't
understod the "me" of "the professor wants me to write a program [...]"

read(2) and write(2) do not normally fail unexpectedly.

Note that they may return with EINTR or EAGAIN (depending on what OS)
requiring them to be restarted. This isn't an error, but a result of how
signaling is designed, i.e. to allow a process to immediately respond to a
signal instead of being stuck waiting for input/output.

You would normally create a small loop to repeatedly restart the
read/write if it returns -1 and errno is EAGAIN or EINTR. If you have
signal handlers that sets flag, then you may have to take a peek at these
flags before restarting the operation - for example if your process has
received a signal that it should end, or reopen any log files or reload
configuration...

Function calls that does not have a timeout are often used together with
alarm() to get a SIGALRM after the intended timeout, in case no data is
available.

You may also get these functions to "fail" by manually using the kill or
killall commands and send signals to the application.

With the exception of EIO, all other errors can be produced by sending
incorrect parameters to read()/write() or by manipulating the target that
fd references, such as by closing the other end of a pipe, limiting the
amount of disk space available, ...

 GOOD QUESTION

Subject: [Dev-C++] How to test methods with system calls


I'm testing some c++ programs having some methods with system calls, which
are like write(2) and read(2).
(I use googletest for the test.)

Those write(2) and read(2) can fail for some reason, but
it's not predicable, so I'm wondering how I can test error handling codes
for errors by those system calls.

Is there any way I can simulate those system call' errors without
modification in source code ?
How do you usually test those ?

Thanks in advance,

Hiroyuki
