this for me.
Long story short from time to time I need to us C++ to take a list of
file and make an index out of them in html. for this I use fstream both
for input and output. So, i have a simple file that I just change few
things on and I get the output formatted to what I want.
So I installed FC6 on my home system and get out my handy usb drive
because i needed my magic source file:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
fstream fout("index.html", fstream::out );
fstream fin("list.txt", fstream::in);
int main()
{
string in;
while(getline(fin, in))
{
fout << in << endl;
}
return 0;
}
to compile another html file for me. As you can see pretty cut and dry
and to the point.
My problem is compiling this file since I upgraded(?) to FC6 from FC5. I
am using gcc version 4.1.1 20061011 (Red Hat 4.1.1-30) without any
tweaks or changes from a std install.
When I run:
[charowl@localhost *****]$ gcc stuff.cpp
I get:

collect2: ld returned 1 exit status
and nothing happens. Is my complier broken, my code?
either way it would be nice to know. I have tried using every example
of how to do this that google could find for me on fstream, and now I
ask you. thanks -josh
