GCC compile problems

[brast]

I've recently installed glibc2.3 on my computer, I originally had a prior version, however, I cannot compile a simple C++ program. Not to imply that I could before, because I couldn't, I got an error I thought was due to an antiquated C library. But now I have all new errors.

Here's the coding to the "helloworld.cpp":
_____________________________________
#include <iostream.h>
int main()
{
cout << "Hello World!\n";
return 0;
}
_____________________________________

Here's the error message:
_____________________________________
[brast@localhost brast]$ gcc ./C/helloworld.cpp
In file included from /usr/include/c++/3.2/backward/iostream.h:31,
from C/helloworld.cpp:1:

<<<<and it continues on like that for a while until it goes>>>>
collect2: ld returned 1 exit status

Any help is appreciated.

you don't compile c++ programs with gcc, use g++ instead

I get the same error message with g++
