Dear all,
I wrote a small program prog1.cpp that cranks out the numbers in the sequence A016278 in OEIS
http://www.research.att.com/~njas/sequences/A016278
The program runs on slax, but fails to do so on rawhide.
[olivares at localhost Documents]$ cat prog1.cpp
#include <iostream.h>
#include <stdlib.h>
#include <math.h>
int main(int argc, char *argv[])
{
int i;
double j;
for (i=1; i < 16; i++)
{
j =
(4.0/7.0)*pow(2.0,i-1)+(-3.0/2.0)*pow(3.0,i-1)+(27.0/14.0)*pow(9.0,i-1);
cout << i << ' ' << j << "\n";
}
return EXIT_SUCCESS;
}
[olivares at localhost Documents]$ cat /etc/fedora-release
Fedora release 8.93 (Rawhide)
[olivares at localhost Documents]$ c++ -o prog1 prog1.cpp
prog1.cpp:1:22: error: iostream.h: No such file or directory
prog1.cpp: In function ‘int main(int, char**)’:
prog1.cpp:13: error: ‘cout’ was not declared in this scope
[olivares at localhost Documents]$
On slax 6.0.5/6.0.6 it runs fine although with some warnings:
root at slax:~# c++ -o prog1 prog1.cpp
In file included from
/usr/lib/gcc/i486-slackware-linux/4.2.3/../../../../include/c++/4.2.3/backward/iostream.h:31,
from prog1.cpp:1:
/usr/lib/gcc/i486-slackware-linux/4.2.3/../../../../include/c++/4.2.3/backward/backward_warning.h:32:2:
warning: #warning This file includes at least one
deprecated or antiquated header. Please consider using
one of the 32 headers found in section 17.4.1.2 of the
C++ standard. Examples include substituting the <X>
header for the <X.h> header for C++ includes, or
<iostream> instead of the deprecated header
<iostream.h>. To disable this warning use
-Wno-deprecated.
root at slax:~# ./prog1
1 1
2 14
3 145
4 1370
5 12541
6 113534
....,
Is there something that needs to be done so that the program can compile fine in rawhide?
TIA,
Antonio
