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

Just wondering, which version is in that DevPack? Still the 2.0.0? Or 2.2.1?

[David M. <dem...@uw...>]

Did you download the GTK+ devpak?  You can get it on
http:\\www.bloodshed.net\dev\ in the package repository.  It has a built in
template with all compiler flags, it also has all the correct libs and
headers.

The  behaviour of the above is undefined (e.g. the airplane may crash).
fflush() is intended to be used on output streams.

You can simply do:

getchar();



>    gets(name);


Extremelly Dangerous for buffer overflow (that is you must trust the user
very well, and he user must know the internals of your code). A better one:

fgets(name,10,stdin);

scanf() leaves the '\n' on the stream. Then gets() was reading and
interpreting it as if you entered an empty string.



> 2-What is the solution for don´t use the fflush?


getchar(); or something. You can even do a function in the style:


void clean_stdin()
{
  while(getchar()!='\n')
       ;
}



And use it. If you are going to use it with stream redirection in the style


myprogram <whatever.txt


for example,

you have to get EOF into account.

Re: [Dev-C++] scanf with gets

[Per W. <pw...@ia...>]

But fflush() is not portable for input streams!

It is only indended for flushing output streams. On a Linux, it would
return EOF and set errno to EBADF if the stream isn't opened for output.

Re: [Dev-C++] scanf with gets

[Ricardo R. <ri...@un...>]

scanf ( ) doesnot read the 'return' char,
then it stays in the input buffer until the next reading.
Two options for the next sentence:
(1) If you read in the next sentence with gets( )
the 'return' char is transformed in the
empty char string:  " " = '\0' .
(2) If you read a char in the next sentence with scanf( )
the 'return' char it is transformed in the 'line jump'='\n'.

In consequence, if you dont want any strange/side effect in your input
the best option I know after an entry with scanf( ) it's to free the 
input buffer:

             fflush(stdin).


Any other explanation is wellcome,
but I hope it can help you,
Ricardo.

[Dev-C++] scanf with gets

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

Dear programmers,

I´m having to use the fflush command in the following code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
   char name[10];
   int a, b, c;

   printf("Enter a-->");
   scanf("%d", &a);
   printf("Enter some name-->");
   fflush(stdin);
   gets(name);
   printf("Enter com b-->");
   scanf("%d", &b);
   printf("The sum of %d with %d is %d\n", a, b, a+b);
   printf("And the name typed was %s\n", name);
   system("PAUSE");
   return 0;
}

The reason is that if I don´t put it, the program doesn´t wait for the name
to be typed via keyboard. It passes directly to the other operator, b,
indicating that the input buffer is loaded with something. I made some
experiments with short int (hd), but nothing solved.

1-Can anyone explain what is happening?
2-What is the solution for don´t use the fflush?

Regards
Andre

You need the dev files for GTK+ 2.2.1; this one requires glib, atk, pango,
zlib, libpng, libjpeg and libtiff (this is written on that page), so you
also need to download them (the dev version, if there's more than one).
Unzip everything on dev-cpp's directory (or under MinGW's directory, if you
have it installed somewhere else);

Download the pkg-config too; if you use a unix-like shell (like MSYS) you
can use it to compile your gtk programs, like on the Gtk documentation:

gcc program.c -o program.exe `pkg-config gtk+-2.0 --libs --cflags`


If you don't want to use a shell to compile your programs, you'll need to
copy/paste the output for:


C (or C++) Compiler Flags:

  pkg-config gtk+-2.0 --cflags

  (it will return something like:
        -IC:/DEV-CPP/include/gtk-2.0
        -IC:/DEV-CPP/lib/gtk-2.0/include
        -IC:/DEV-CPP/include/atk-1.0
        -IC:/DEV-CPP/include/pango-1.0
        -IC:/DEV-CPP/include/glib-2.0
        -IC:/DEV-CPP/lib/glib-2.0/include
  )



Linker Options:

  pkg-config gtk+-2.0 --libs

  (will be something like:
        -LC:/DEV-CPP/lib
        -lgtk-win32-2.0
        -lgdk-win32-2.0
        -latk-1.0
        -lgdk_pixbuf-2.0
        -lpangowin32-1.0
        -lgdi32
        -lpango-1.0
        -lgobject-2.0
        -lgmodule-2.0
        -lglib-2.0
        -lintl
        -liconv
  )



So, you can copy/paste it on a GTK+ project on Dev-Cpp. Oh, one more thing:
add the "-mms-bitfields" to the C/C++ flags.


Optionally, you can use this as your GTK+ Template (I use this one):

        gtk_widget_show(win);

        gtk_main();
}

[Dev-C++] GTK + step by step HOW-TO

[<fla...@ya...>]

Dear Sirs:

I would like to use GTK+ with Dev-Cpp. 

I downloaded the newest Dev-Cpp version, however I do
not know how to integrate GTK+ with Dev-Cpp.

In the following web site
http://www.gimp.org/~tml/gimp/win32/
I got many libs and files, I am completely lost!

I need help and directions on which files I have to
download.
Then I step by step procedure on how to integrate it.
compiler flags, etc.

I tried to browse this list files, but I could not get
clear information ( at least to me ) on how to do
that.

I promisse that If I could get through this, I will
place a HOW-TO on the web and I will sent it to
integrate to Dev-Cpp help.

Please, help me!

Regards,

Flávio.

For accuracy you were returning a char.

Re: [Dev-C++] FileContent function...

[Per W. <pw...@ia...>]

There are mail encodings that uses a '=' and some more characters to
encode non-printable characters. Since the '=' is a break character, a
normal '=' must then also be encoded - in this case with '=3D'.

The mail sender program - or your receiving program - failed to process
this encoding correctly. Wherever you see '=3D' the real text just
contains an '=' character.

One issue with the '=xx' encoding is that some versions of mail
encoders (I think of M$ brand) forgets to convert the single '=' to
'=3D' breaking a lot of decoding software.

FileContent returns a char. You assign it to an array which is not proper.
If you intend it to return a char, you have to do something like:

text[0]=FileContent("temp.txt");


If you made a mistake and intend to return a char * you have either to do:


char *text;

/* ... */

text=FileContent("temp.txt");


or


char text[3000];
char *p;

/* ... */

p=FileContent("temp.txt");

strncpy(text, p, 3000);

text[2999]='\0';

// If FileContent already keeps the full text content, no need for one
// more buffer. Just keep track of a pointer to the text.
// Besides, it isn't possible to assign an array to an array. As Ioannis

When You have a lib*.a, you have to tell to the compiler, You want to use
it. So in the "Project Options" / "Parameters" / "Linker" fill a new
line: -l*

In Your case: -ltiff

Hi,

trying to compile a simple SDL-Sample results in this:

g++.exe Main.o  -o "Template.exe" -L"C:/dev/Dev-Cpp/lib" =
-L"C:/dev/wx/lib" -L"C:/dev/wx/contrib/lib" -L"C:/dev/SDL/lib" SDL.lib =
SDLmain.lib
g++.exe: SDL.lib: No such file or directory
g++.exe: SDLmain.lib: No such file or directory
make.exe: *** [Template.exe] Error 1

However, SDL.lib and SDLmain.lib are present in C:\dev\SDL\lib, which is =
also entered in the compiler options.
This occurs with all libs, also wxWindows and other toolkits.

Can somebody help me??

Looks like what you actually want is something like this:

char *FileContent(file *fp)
{
  char *buf;
  // Open the file...
  int i =3D fseek(fp, SEEK_END) + 1;
  buf =3D malloc(sizeof(i));
  fseek(fp, SEEK_SET);
  for(char ch =3D fgetc(fp); ch !=3D EOF; buf++ =3D ch);
  return buf;
}

I think this should work at least.  The code is off the top of my head and
untested.

What does the '=3D' do in the above function??

Yep.  I had the other stuff, but was missing the char *FileContent....

Looks like what you actually want is something like this:

char *FileContent(file *fp)
{
  char *buf;
  // Open the file...
  int i = fseek(fp, SEEK_END) + 1;
  buf = malloc(sizeof(i));
  fseek(fp, SEEK_SET);
  for(char ch = fgetc(fp); ch != EOF; buf++ = ch);
  return buf;
}

I think this should work at least.  The code is off the top of my head and
untested.

Per,

this worked!  Thanks!  I had the code correct, but I was returning a string
instead of a string pointer.

thanks,

Yes structs can have a constructor (I assume you do not have it in private
access, and it is a .cpp file).

There are not older standards for C++. The first is the last one, the
ANSI/ISO C++ 14882:1998 standard (there is/will be an intermediate revision
this year, which is "bug fixes").

Should be malloc(i); instead :\

Re: [Dev-C++] Re: Conio AND a question

[Per W. <pw...@ia...>]

A struct and a class is just about the same.

The main difference is that a struct has default public access, while a
class requires you to write protected: or public: if you want to access
the contents.

[Dev-C++] Re: Conio AND a question

[Samuel K. <ib...@ly...>]

To the person that was trying to use some borland functions in the conio.h file. I had the same problem until somebody told me to #include <conio.c> which worked for me.

And now my question:

I have toyed with borland C++ 5.5, the free downloadable version. It reported a bunch of syntax errors for a source file that compiled fine under dev C++ using the minGW compiler. Some of the syntax errors appeared to be centered on the fact that I had a constructor in a structure. According to ANSI C++, can a structure have a constructor? Did they allow structures to have constructor's in older standards?

Looks like what you actually want is something like this:

char *FileContent(file *fp)
{
  char *buf;
  // Open the file...
  int i =3D fseek(fp, SEEK_END) + 1;
  buf =3D malloc(sizeof(i));
  fseek(fp, SEEK_SET);
  for(char ch =3D fgetc(fp); ch !=3D EOF; buf++ =3D ch);
  return buf;
}

untested.
