GCC problems

[katana]

Sorry for the real newbie questions, but I have another.
I'm having errors using the ./configure command to install a package. It says my c compiler cannot create executables. I decided to test my gcc compiler by writing a simple "hello world" c++ program, and this was the output I got:
[root@localhost test]# g++ -o mytest mytest.cpp
mytest.cpp:1:22: iostream.h: No such file or directory
mytest.cpp: In function `int main()':
mytest.cpp:4: error: `cout' undeclared (first use this function)
mytest.cpp:4: error: (Each undeclared identifier is reported only once for each
function it appears in.)
mytest.cpp:4: error: `endl' undeclared (first use this function)

can anyone tell me what is wrong?
cheers
Darren.

If you're going to compile, you probably should install all the RPMs listed as Development packages because they will install all the header files (iostream.h included).

[Jman]

Did you install the Development Tools in the Development category? Main Menu > System Settings > Add/Remove Applications if not.

also, it'd be a good idea to change

#include <iostream.h>

in your c++ program, to

#include <iostream>
using namespace std;

as the use of the .h extension for including iostream is deprecated.. but as they say, you need to install the header files first : )
