Some details would be really good. ie, example program you tried, g++ 
compile command you used ??.
Here is a simple one:

#include <iostream>


/*using namespace std;*/
int main (int argc, char **argv)
{
         cout << "Hello world\n";
         }

Notice the /*using namespace std;*/ bit. You either uncomment it, or 
use full qualification to cout  ( std::cout)

You need these rpm packages installed:

gcc-c++-3.3.2-1
libstdc++-devel-3.3.2-1

and possibly compat-libstdc++-devel-7.3-2.96.118 depending on what you 
are doing..

Note that these are probably not the versions that come with ISO of 
Fedora, I keep my system up to date with yum.

Finally how to compile it - 'g++ -o Hello Hello.cpp'  will compile 
source file Hello.cpp and save the binary in 'Hello' .

Cheers,
Michael
