What's the difference between adding a lib file (ie libuser32.a) to the
linker parameter list VS. adding a -luser32 to the compiler parameter
list?

Thanks,
P

#include <stdlib.h>

This is the era I get what am I doing wrong


 implicit declaration of function `int rand(...)'

#incude <stdio.h>

main()
 {
  int target;
  int guess;
  int again;


 printf("\n Do you want to guess a number 1=3Dyes, 0=3Dno");
 scanf("%d",&again);

  while (again)
  {
  target=3Drand()%100;

printf("\n What is your guess ? ");
scanf("%d",&guess);

  while(target!=3Dguess)
  {
  if(target>guess)printf(" Too low ");
  else printf(" too high ");
  printf("\n What is your guess ? ");
  scanf("%d" ,&guess);
  }

  printf("\n Well done you got it! \n");
  printf("\n Do you want to guess a number 1=3Dyes, 0=3Dno");
  scanf("%d",&again);
   }
}

yes, you need to link against 'libmsvcr70.a', just adding -lmsvcr70 to
the linker flags schould be also ok.
Just a small hint:
If you have some undefined references, this is mostly because you have
forgotten to link against something. You can solve this by grepping
through your lib directy. For Example you want to find in which file the
btowc function resides:

1. Open a command prompt (Under winnt-systems Start->run->cmd)
2. Change to your lib dirrectory (Its in your Dev-Cpp directory)
3. grep after your string, in our example you have to do 'grep btowc *'
(If you don't have grep you can obtain it from
http://gnuwin32.sourceforge.net/packages/grep.htm)
Then all files which contains this string are listed.

This method doesn't help all the time, but in most cases you'll find a
~ 	appropriate lib to link against.

HTH

Tim

Daniel K. O.

Hello!

I want to use GTK+ package with DevC++ 4.9.8.7
But both of the links in the download section on the page
http://bloodshed.net/dev/packages/gtk.html aren`t work :(

I downloaded DevEx (GTK Extension for Dev-C++) from
http://wingtk.sourceforge.net/. When I ran it asked me to specify
DevC++ path. When I specified it tell me there is no devc++ in that
directory :(

What can I do? Where can I find GTK+ package?
There is no such package in WebUpdate module :(


Another question is how can I upgrade my devc++ to 4.9.8.9?
I tried to do it with WebUpdate module, but it said I must close
devc++ window first. When I closed it, devc++ closed WebUpdate window
too. And now I have DevC++ 4.9.8.7 and no DevC++ 4.9.8.9 in the list
of availible updates in the WebUpdate :(

Hello all,

I am trying to compile and test greta. It compiles
fine.
I downloaded a sample program and am trying to compile
it.
Here again it compiles fine but the linker gives two
undefined reference errors:

1. undefined reference to 'wctype'
2. undefined reference to 'btowc'

Do I have to link some other libraries while I
compile?
If yes, which ones?

TIA

Siva Chandra.

You have to allocate memory for the structure before allocate the array
inside.

I have writed a simple program just only construct two empty linear list.The process of compile is no problem.But after run it,the system crash occur.If I remove the sentence (2),the problem will not come.Can 
anyone tell me how to do If I want to use the function InitList() separate to construct two empty list?

My program list below:
/*  A simple program that want to construct two empty linear list */
#define LIST_INIT_SIZE   10

    int     length;     /*the linear list current length */ 
    int     listsize;   /* the linear list's space that has distributed */
}LineList;

/* construct a empty linear list */
ARRAY *InitList(LineList *list)
{
    list->elem = (ARRAY *) malloc(LIST_INIT_SIZE * sizeof(ARRAY));
    list->length = 0;
    list->listsize = LIST_INIT_SIZE;
    return list->elem;
}
main()
{
    LineList    *list, *list1;

Yes, currently, Dev-C++ does not come with a Visual Resource designer.
You can use VC6 to create the .rc file. Then include the rc file in your
Dev-C++ project.
