Re: [Dev-C++] Using GTK+

[Daniel W. <d_w...@ho...>]

Hi!

Well, maybe you dont have all the things (libraries and such) necessary =
to compile a GTK application, but you can find that things in the =
homepage of Dev-C++ (www.bloodshed.net), there is a link to "packages" =
and there are two packages for GTK, the runtime library and the other =
libraries.

Well hope i helped

Re: [Dev-C++] problem making cgi scripts

[Brian P. <br...@su...>]

If you have mysql installed on your machine it should be in that
directory somewhere (on my RedHat 7.2 installation it is
/usr/include/mysql/mysql.h and on my Windows 2k box it is
c:\mysql\include\mysql.h).

You will need to tell Dev-C++ where this header file is under the
compiler or project options. You will then need to give it the switch:
-lmysqlclient under compiler or project options. If you are compiling
from the command prompt you can type: 

gcc yourprogram.c -oyourprogram.cgi -L/[directory of mysql.h file]
-lmysqlclient

If you are going to work with cgi's you will of course need to make sure
your mysql server is up and running and that it is willing to accept
connection from you (usually localhost if the cgi is running on the same
server as mysql).

I hope that helps.

[Dev-C++] failed.

[Peter <pet...@sp...>]

I tried the Hello World program in C++ 101. It failed miserably with a
blue screen of death. I used Control F9 and then F9. Should I try to run
it in a Dos window. and how can a cpp extension run? Does it not have to
be exe?

No, always use vectors and if in need to squeeze every cycle out in
terms of speed use valarrays (they have the speed of optimised Fortran
arrays).

Thanks.

A vector (stop me if I've over-generalised this or am just plain wrong
ppl) is an array with built in features such as error checking but can,
unless used perfectly, use more resources.

 

Is that ok everyone?
 

:) No. One pays for what he uses. If you need features that occupy some
resources, you would occupy the same resources and even more if you use
built in arrays and functions getting them as arguments and twiddling
their bits. Standard library containers are made small in such way so as
the member functions are inlined and we have no time cost. In fact
usually we have less time cost than C style code separated in functions!
For an example see my tests at:
http://users.forthnet.gr/ath/jvr/c++faq.htm

This is a mistake. The proper ANSI C++ header style is #include
<iostream> . iostream.h e.t.c is illegal, in all modern compilers is
depricated and is about to removed from future versions.

HEY GUYS,
 
I'm that newbie guy that keeps having trouble.  I got a book "C++ for
the absolute beginner," well this beginner doesn't still get it.  So I'm
wondering if you can explain what the book is failing to explain.  Below
is a program I typed in, that is giving me fits over "enum" and all its
"returns" I feel like I missing something in my lib.'s but I'm not sure.
I have double checked everything several times to the book and from all
that I can see I have typed it out just as the book has it.  I take it
though one complier will do things differently than another and I know
the author is using a different complier.  So if anyone can help me I'm
all ears.  
 
enums are user defined discrete integer types.

Re: [Dev-C++] Windows Programing

[Benjamin W. <ben...@ho...>]

Good morning,

We've had this question not too long ago.  My recommendation is Charles 
Petzold's -- Programming Windows, 5th Ed.  His web site is:

http://www.charlespetzold.com/home.html

It's a hardback, 1500+ page book that covers the Win32 API better than any 
other book I have ever read.  If you are serious about Windows programming, 
you really should pick up a copy.

Hope that helps.

[Dev-C++] How to avoid <macro or recursion too deep> message

[Santiago P. C. <San...@yd...>]

Hi to *,

I'm trying to do 'some_kind_of_port' (I'm not so good programmer to be sure
of achiveing that, but I must try ;oD) of a Linux app to Windoze, but I'm
finding a lot of errors like this one:

D:/path/to/include/folder/include_file.h: macro or `#include' recursion too
deep

I know this error uses to appear when invoking g++ with '-traditional' flag,
but this is not the case, here is my command line:

g++ -mconsole -mthreads -shared -c D:\usr\ports\unix\config.cxx
-I"D:\usr\ports\include" -I"D:\usr\libs\include" -L"D:\usr\ports\lib"
-L"D:\usr\libs\lib"

AFAIK this should be solved by using the following structure on all include
files:

#idnfdef __LIBRARY_NAME__FILENAME_H__
#define __LIBRARY_NAME__FILENAME_H__
... File contents
#endif

But, due to the fact that I'm using 'external' libs (like PWLib) it is not
possible to modify all include files (everytime a new version of the library
is released) to keep them using this structure (and I also think this is not
the solution).

I'm relatively new to MinGW and Dev-C++ so, any hints on where should I look
at?

Thanx,
	Santy

I have Dev-C++ 4.0 but I use ConTEXT most of the times (in fact it enables 
me to harness powerful Borland BC++ 5.5 compiler): I only write console 
programs so probably what I say does not suit your case (I know nothing

I don't miss it :) In fact, ConTEXT has projects too (they allow too keep 
files together, a sort of putting all the sheets in one folder) and also I 
use a makefile generator which creates "makefiles" that manage programs 
whose source code is spread across more than one file.

sorry, too difficult for me to answer.

>Generally can I use make to compile in Dev C++.

I don't think so, in fact Dev C++ only compiles "projects". Using "make", 
would mean that Dev C++ had the ability to convert a "makefile" into a 
"project", and this is something that vers. 4.0 of the program doesn't do, 
it does the opposite though: I mean that you can write a project (using 
Dev-C++) then generate a makefile out of the project (actually the result 
is not a "smart" makefile), finally use "make" and the makefile to compile 
your program.

[Dev-C++] vectors

[Graeme F. <gr...@dr...>]

What is a vector?
=================
In short a vector one of the containers provided by the Standard Template
Library. A container is a data type that allows objects of a similar type to
be held together. A template allows the data type to be declared when the
container is created. The characteristics of the vector is that it is
dynamic - that means that when a new element is to be added to the container
then that is done automatically. New elements are added to the end of the
vector, for most efficient results the elements should also be deleted from
the end but it is possible to delete elements from anywhere from within the
vector. Elements in the vector can be accessed randomly using the []
operators just like the array.

So is a vector like an array?
=============================
I guess that you could say that it's like an array on steroids. It can do
much more than a simple array but with a familiar interface.

When should an array be used and when should a vector be used?
==============================================================
If you know before hand how many elements will be used then use an array, if
however the number of elements is not known then use a vector.

What did you mean by a vector allowing "objects of a similar type to be held
together"?
============================================================================
===========
The similar type refers to classes within the class hierarchy. The class
defined as the template can be used along with any derived class. Hence a
vector of person objects will also be able to hold students objects and
lecturer objects, so long as both of these objects are derived from the
person class.


Please give me an example!
==========================

The following may help to clarify things:

I have declared a class called allObjects which contains a vector of
instances of the cObject class:
+++++++++++++++++++++++++++++++++++
class cAllObjects
{
   private:
      vector<cObject *> list;
   public:
      void add(cObject * obj);
      void remove (cObject * obj);
      cObject * get (long OID);
      void dump();
};

The definitions are as follows:
+++++++++++++++++++++++++++++++++++
void cAllObjects::add(cObject * obj)
{
	list.push_back(obj);
}

void cAllObjects::remove (cObject * obj)
{
	list.erase(find(list.begin(), list.end(), obj));
}

cObject * cAllObjects::get (long OID)
{
   unsigned int i = 0;
	while (i < list.size() && list[i]->OID != OID)
   {
   	i++;
   }
   if (i >= list.size())
   	return 0;
   else
   	return list[i];
}

void cAllObjects::dump()
{
	for (int i = 0; i < list.size(); i++)
   	list[i]->dump();
}

For this to work the cObject needs to be declared and defined:
+++++++++++++++++++++++++++++++++++
class cAllObjects;
class cObject
{
   friend cAllObjects;
   private:
      static long nextOID;
      static cAllObjects allObjects;
      long        OID;
      string      className;
   public:
      static void dumpAll();
      cObject(long pOID = nextOID);
      ~cObject();
      void dump();
};

and:
+++++++++++++++++++++++++++++++++++
#include "Object.hpp"

// Initialise the Static members
long cObject::nextOID = 0;
cAllObjects cObject::allObjects;

void cObject::dumpAll()
{
	allObjects.dump();
}

// Constructors
cObject::cObject(long pOID)
{
	// Add this object to the list
   allObjects.add(this);
   // Check that the OID hasn't yet been used
   if (pOID < nextOID)
      pOID = nextOID;
   OID = pOID;				// assign the unique number to OID
   nextOID = pOID + 1;	// increment the nextOID by 1
   className = "Object";// set the class name to Object
}

// Destructors
cObject::~cObject()
{
   // Remove this object from the AllObjects list
   allObjects.remove(this);
}

// Diagnostic methods
void cObject::dump()
{
   cout << "OID   = " << OID << "\n";
   cout << "Class = " << className << "\n";
}

This can then be tested using the following main:
int main(int argc, char* argv[])
{
   cObject myObject1(5);
   myObject1.dump();
   cObject myObject2(0);
   myObject2.dump();
   cObject myObject3(0);
   myObject3.dump();
   cObject myObject4;
   myObject4.dump();
   cObject::dumpAll();
   cout << "Press any key to finish...\n";
   getch();
   return 0;
}

Files
=====
The declarations of both classes are held in the same file called
Object.hpp, whilst  the source code was held in the their own files.

This enables an object to hold all of teh objects that have been created,
they are put onto the vector from within the constructor of the cObject
class. They can all be listed by using the static member function dumpAll()

Re: [Dev-C++] errors

[Jason H. <jas...@bt...>]

The errors you are getting are all due to simple typing errors. If you =
look in the enum you have substituted the number 0 with the letter O, =
notice the subtle difference in width between letter and number. So =
where you have previously put zero you need to put the letter O, but =
only for the lines dealing with the enumeration, and returning an =
enumeration type. Another mistype you have is where a ) bracket has been =
substituted for a } brace.

If you go through the errors double clicking the top one and correct the =
error, and then recompiling eventualy you will get a full compile. =
However I suggest you look at the code as the game doesn't apear to work =
properly, so there may be other more subtle erros, maybe mistyped =
numbers etc...

Re: [Dev-C++] Problems

[Jason H. <jas...@bt...>]

As I understand it 4.9.1 is a beta (alpha?) release for the upcoming v5 of
Dev-C++ so it's bound to be little buggy. Your best bet would be to report
the problems you are having. They will need more information about the exact
steps you are taking and the system you are working with before they can
adivise you and fix the problem.

For a more stable release try v4.01.

Jason.

Re: [Dev-C++] Problems

[Daniel W. <d_w...@ho...>]

What happen is that the version 4.9.1 is a beta version and beta means =
crashes and bugs, i downloaded that version but for the same problem i =
downloaded the version 4.0.1

I think is for that

  Nothing. Version 4.9.1 is code named Dev-C++ 5 Beta, so it is pretty
buggy. I would suggest that you use the older version until all the bugs are
worked out (you help speed the process up by submitting bug reports :) ).
You can get the old version at http://www.bloodshed.net/dev/devcpp.html .
Scroll down until you see the section entitled 'Dev-C++ 4'.

Sincerely,
Brian Becker

RES: [Dev-C++] errors

[Daniel K. O. <dan...@ya...>]

Try putting your includes like this:

	#include <iostream.h>
	#include <string.h>



And I noticed the identifiers you're using in the enum type:

	enum SquareState { blank = ' ' , X =  'X', 0= '0' };

Look: you're using 0 (zero) instead O (letter). Identifiers shouldn't start
with a digit, like 0 (zero).
The same where you're returning zero instead O.


Hope this can help you.

[Dev-C++] errors

[Danny A. <tam...@ms...>]

HEY GUYS,

I'm that newbie guy that keeps having trouble.  I got a book "C++ for the=
 absolute beginner," well this beginner doesn't still get it.  So I'm won=
dering if you can explain what the book is failing to explain.  Below is =
a program I typed in, that is giving me fits over "enum" and all its "ret=
urns" I feel like I missing something in my lib.'s but I'm not sure.  I h=
ave double checked everything several times to the book and from all that=
 I can see I have typed it out just as the book has it.  I take it though=
 one complier will do things differently than another and I know the auth=
or is using a different complier.  So if anyone can help me I'm all ears.=

[Dev-C++] Problems

[Daniel K. O. <dan...@ya...>]

Hello people


I'm new on Dev-C++, and I'm having some problems with the version 4.9.1

It crashes all the time, when I try to compile something, and I get a bsod.

What I'm doing wrong?





Thanks for any help.

Re: [Dev-C++] Struct tag

[Daniel W. <d_w...@ho...>]

OK, i ll answer your first question, the second: what the heck is a =
vector, i dont know

the difference between classes and structs is that in a class all the =
members are, for default, private, and in a struct are public by =
default. No more, thats the difference.
