it's been a while since i've used it, but i think that if you want to run the program on XP, cygwin is the way to go. but, if you want to compile the program on XP to run on a Linux machine, the process is very complicated - IIRC, you have to rebuild all the tools (gc, the linker, the libraries, maybe even the kernel) first.

a few years ago, i needed to build an EXE that could run on a specific Linux distribution, and i went down they cygwin path for a few days, trying to get it to work; but it quickly became far too much hassle. i ended up spending a couple hundred $ to buy a cheap PC, installed the Linux distribution on it and built the EXE there. then i moved the EXE to the target computer, and got on with my life.

What kind of program is it ? Was it planned to be cross-platform ? If no, then as far as I know you can't do that. But it all depends of the program itself. If it is a simple console application that doesn't use any linux API, then it is cross-platfrom. If it is a program that display a GUI for instance using the Linux API, then it won't work.

cygwin is great.

I was using to compile a 3d game. For the past two days i was sitting on this.
The only problem is initial setting up of the libraries and headers and then too download the cygwin packages you require.

hi iam doing a project with my friends, and its about find the posbile path of the linklist

and one of the function is wrong

i got the struct

struct node
{
int v1;
int v2;
int w;
}first;

struct node[] *findposibility(int index) // is this wrong the way i call the node
{
struct node *curr;
struct node *a[5];
curr = first;
int i = 0;

while(curr->next != NULL)
{
if(index = curr->v1)
{
a[i] = cur;
i++;
}
curr == curr->next;
}
return a;
}
thanks

Where's the "next" member of node?

There's several problems involving uninitialized variables and your function definition.

What are you trying to do?

hi sory i forgot to put the next

and one of the function is wrong

i got the struct

struct node
{
int v1;
int v2;
int w;
struct node *next
}first;

struct node[] *findposibility(int index) // is this wrong the way i call the node
{
struct node *curr;
struct node *a[5];
curr = first;
int i = 0;

while(curr->next != NULL)
{
if(index = curr->v1)
{
a[i] = cur;
i++;
}
curr == curr->next;
}
return a;
}
thanks

One way to get your code to compile is like this (changes in red):

struct node
{
   int v1;
   int v2;
   int w;
   struct node *next;
} first;
 
struct <code>node **</code>findposibility(int index) 
{
   struct node *curr = <code>&</code>first;
   <code>static</code> struct node *a[5];
   int i = 0;
 
   while(curr->next != NULL)
   {
      if(index <code>==</code> curr->v1)
      {
         a[i] = curr;
         i++;
      }
      curr <code>=</code> curr->next;
   }
   return a;
}

There's still a couple problems:
1) first is not initialized
2) Is 5 the max number of hits you will ever encounter?

THANKS ITS HELP ME alot actually first i declare in another function but i want to ask u why i have to put static instead of struct node *a[5]?

That's the only way to "return a;" safely. If "a" is not static then it is a temporary variable
that only exists (its scope) in this case for the life of the function. If you return it, and
it doesn't exist after returning, then that's quite a problem.
