The question does not have to be directly related to Linux and any language is fair game.

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.

THAT WAS IT! After I added where the includes lived (/usr/..../g++) the file compiled with out the -lstdc++ option (that is really lazy of me! I spend two days looking for a way not to type in eight characters every time I compile )
I'm having a similar problem but not having any luck. I'm trying to compile the "helloworld.cpp" program and getting the following error:
helloworld.cpp: In function `int main()':
helloworld.cpp:5: `cout' undeclared (first use this function)
helloworld.cpp:5: (Each undeclared identifier is reported only once for each function it appears in.)
helloworld.cpp:5: `endl' undeclared (first use this function)
The code is:
I tried the solutions that you guys tried (including 'gcc file.cpp -lstdc++) but they didn't work. I think my C++ libraries are in /usr/include/c++/3.2. The iostream lib is there. Any thoughts? Thanks.
Because namespaces make sense,
and the new standard requires either
adding the namespace to the function,
or the "using namespace std" at the
beginning. The latter (even though more
convenient) is considered worse style.
EDIT Will someone who can plz delete this, silly me didn't see the part about prefixing std:: before cout, etc. That fixed it. But still, why is the std:: part necessary, i have used gcc before and it didn't require this. /EDIT
i have had the same problem, i use g++ 3.2.3. the headers are
using namespace std;
BUT it still spouts forth about 30 error messages that even i can't understand.
