Hi,

When I run a console-app, written in C++ on Borland Kylix - platform = Mandrake 9.0/Intel Celeron - I notice that arythmetic operators used with anything else than integers just don't work.

It seems i can only calculate with ints.
As far as i know all the usual headerfiles are in /usr/include.
Anyway, iostream (iostream.h) should do, no?

I added /usr/include, /usr/include/C++/3.2 , /lib, /lib/include and some other paths in different options of the IDE.

But.....this makes no difference.

I'm new to Kylix (and relatively new to Linux) but I really like this IDE. But if i can only use ints , then of course its useless.

I surely must have overlooked something. Anybody an idea ?

Thanx

Maybe if you were a bit more specific,
like posting the snippet that doesn't work?

Cheers,

well, it's a general problem really.

As long as I use ints in my code, no problem.
But if i use longs, floats or doubles the built application will simply not perform the calculations.

Any example will do, so I taken the calculation of the average in an array of longs.

#include <iostream.h>

using namespace std;

const int size = 5;

int main(){
long array[size] = {x , x, x, x, x } ; //where x is a long
double avg = 0.0;
long res = 0;

for(int i = 0; i < size; i++){
res += array[i];
}

avg = static_cast <double>(res) / size;

cout << avg << endl;

return 0;
}

OK, if i compile this piece of code , I just get the output : " 0 ";
Which means the calculations is just not done and the variable avg just keeps its initial value.

I'm really starting to wonder if this is not a general linux problem.
I have this problem on a laptop running Mandrake 9.
On a desktop running Mandrake 8.1 i also use Kylix and there i don't have this problem.
The thing is, i can't always work on my desktop, and i'm not so experienced in both linux and C++ , so i really prefer an IDE over the gcc .
