[Dev-C++] (no subject)

[Tassos T. <atz...@at...>]

Whenever I include stdio.h(#include <stdio.h>) I get a compiler message =
that there is an syntax error in 2 line of stdio.h.

line 221: "extern inline int vsnprintf (char* s, size_t n, const char* =
format,"
line 375: "extern inline int vsnwprintf (wchar_t* s, size_t n, const =
wchar_t* format,"
My programs still run even though I never include that library but one =
day they might not.What can I do to fix that problem?

Re: [Dev-C++] DirectDraw7

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

You may be #including ddraw.h more than once. Try this little trick -
At the start of each header file, put the following:

#ifndef _MYHEADER_H
#define _MYHEADER_H

// all of your code

// bottom of file
#endif // _MYHEADER_H

This prevents Multiple Inclusion, so header files only get included once.

[Dev-C++] Profile Analysis

[Russell <rj...@dy...>]

Every time I try to run a Profile Analysis on my project, it returns the 
message:

“Please run the project at least once so that profiling info is 
generated...”

I've run my prject numerous times, and set all the options which should 
allow this to work. In addition, I've searched Google, and asked many 
people for help and have received nothing.

Could someone please explain the process of running the aforementioned 
feature, please?

Generally setting the "create debung info" to "on", is a one time 
operation. Do you mean that in your case, Dev-C++ does not retain
the setting between sessions?

As for enabling it automatically, default of Gcc is not to include
debug info unless user explicitly requires that, I guess that leaving
out debug info makes binary files smalles and faster to execute.

Asking user when the debug button is pressed would be too late :-)
Unless one is willing also to rebuild

Guessing: could it be that you have some pieces of code compiled with 
"Debug info" turned "on" and some with that option turned "off" ?

[Dev-C++] Problems with Debugging

[Michael S. <mic...@nu...>]

Hi,

I recently managed how to get debugging to work in Dev-C++, but I noticed 2
problems:

1. I have to manually enable "create debug info" in the linker settings for
debugging. Perhaps it should be enabled automatically (or by asking the
user) when the "debug"-button is pressed the first time.

2. If I set breakpoints, only the ones in my "int main"-
function are reagrded and processed, but if I set them for example in the
constructor of some of my classes the program never stops there. Also
Dev-C++ says "the .exe file is older than the source-files, do you want to
recompile it?", even if I make a full recompile and then change nothing.

If somebody has an idea how to fix #2, it would be very cool, since I need
debugging very much (as a beginner :)  )

[Dev-C++] using conio with dev-c 4.9.8

[todd b. <tb...@nw...>]

Hiya
I cannot get the conio to work. I have added the file into ->project =
options->parameters->add library or object-> linker

and also the header file and library .o file placements are acknowledged =
in the tools->compiler options->directories-> libraries / c includes / =
c++ includes.

thanks for any idea on this!

Re: [Dev-C++] plugins

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

It shouldn't be - COM is a binary standard meaning COM objects (like dlls) 
can be written in any language. The exe and dll need not be compiled with 
the same compiler, but if the code inside makes assumptions about the code 
it is interacting with (i.e. not portable) you may well have problems.

Does this sound right?

Daniel

That would be pretty hard to answer since we know nothing of your

Parse the contents of the time from your PC clock into it's parts, every
time the "minutes" variable changes, display the time.

Let's see, the name implies that it's an M$ TC/IP header file, in which

Re: [Dev-C++] Exit Codes

[Felipe L. <li...@cp...>]

Andre,

A) you can do the #3 substitution on your own code, something like:
#define EXIT_FAILURE 1
Perhaps it can be done in stdlib.h but i'm not sure.

B)It's true(I guess)

C)If this constant hasnt been defined yet, you can make the substitution.
Try it!

[Dev-C++] Exit Codes

[<and...@su...>]

Dear Users,

1. Every time I finish a code without problems the final code is return 0
for an int main()
   function;
2. But, if exists inside the code a primary condition for the code run I use
a piece of
   code like the following:
   ...
   char *ptr;

   ptr=malloc(10*sizeof(char));
   if(!ptr)
   {
      printf("no mem");
      exit(1);
   }
   ...
   That is, I scape in advance of the execution because lack of resources;
3. It´s my interest to change the zero of the 1 statement for an
EXIT_SUCCESS stdlib.h constant;
4. I couldn´t find an constant for 1 in an EXIT style;
5. I think I can´t change an exit(1) for an exit(EXIT_FAILURE) because this
constant is equal to
   -1;

My Questions:
A) Can I make the #3 substitution?
B) Is that true the #4 statement?
C) Can I make the #5 substitution?

Andre

Good peopleHi,

I'm starting my self with learning C so I can't help you a lot. However I do
know that C contains a header called "time.h" it has all kinds of time
related functions.

As for the autop update thing the only thing I can think of is use a timer
(do you have timers in C/C+?) or make your appliction run with AT on windows
NT or cron (*nix) automaticly.

Re: [Dev-C++] directories and files library

[Yeoh H. <ye...@ye...>]

Yes, there are. You might want to check this out:

Here is an extract:
The Boost Filesystem Library provides portable facilities to query and
manipulate paths, files, and directories.
The motivation for the library is the need to be able to perform portable
script-like operations from within C++ programs. The intent is not to
compete with Python, Perl, or shell languages, but rather to provide
portable filesystem operations when C++ is already the language of choice.
The design encourages, but does not require, safe and portable filesystem
usage.
