gcc/g++ fails to compile

gcc/g++ fails to compile

[Phil C]

Every
time I try and complie with g++ it fails, even on the simplest of jobs.
"hello world" even failed to compile. I don't have the error messages
handy at the moment, but I remember them being something about improper
function calling (? maybe). I refrenced the standard that the version I
use uses (Version 4.3) and couldn't find any issues with the codeing
either. Any ideas? Is it possible that gcc/g++ itself is broken and
needs a fresh compile?

If it's necessary to have the error output I will post that as well.

Thanks

Sorry for the lack of information I hope this makes the situation more clear. I'm using Ubuntu Linux 8.04 and every current stable patch kernel wise. GCC is version 4.3 Remaining info is as follows.

//Sample Code

#include<iostream>
using namespace std;

int main() {
    cout <<"Hello World";
    return 0;
}

[more "undefined reference" errors snipped]

For linking, you need to either use "g++" (rather than "gcc"), or
explicitly link against the C++ library with "-lstdc++". IOW:

	g++ test.cc
or:
	gcc test.cc -lstdc++

Try 'sudo apt-get install libstdc++6'.
If that doesn't work please provide the exact command you used to
compile.
