Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm new to linux, and I just got a nice redhat 9 system set up. Everything is working the way I want it to, and I am very impressed w/ linux and everything else so far. However, I am having a problem with g++. It doesn't seem to be able to find any libraries. For instance, when compiling the simple hello world program that follows:
cout << "Hello World!\n";
I use the command 'g++ hello.cpp -o hello' and get the following set of error messages:
hello.cpp: In function `int main()':
hello.cpp:5: `cout' undeclared (first use this function)
hello.cpp:5: (Each undeclared identifier is reported only once for each
function it appears in.)
I get the same type of messages if I try to use anything w/ string, even after doing a #include <string>.
It's my understanding that g++ looks in /usr/lib and /lib for libraries when it is doing a complile.
I looked in both of those dirs, and they do have files (this is where I show my c++ newbie status as well) but neither dir had anything called iostream or any related name that i could find.
So I guess the question really is... where are all of the common libraries (like iostream and string) placed on a linux system, what exactly are the files called, and how can I tell g++ to look in those dirs if it isn't allready.
I have read the man page for g++ and also tried extensive googling for an answer to this question, but have not been able to find anything =( Any help that you can offer would be greatly appreciated =)
