help with gcc

[kryptonite0110]

Ive been programming in c++ for a while and when i swiched to linux i didnt like any of the programming interfaces, so i wanted to learn to do it in command line. I cannot get ANY programs to work with ANYTHING on linux in C++. Please help!!!!
(yes i know i am a newbie)

The command you need is

gcc <source file> -o (output file)

To run the compiled file the command is

./<filename>

Don't forget the "./". I do not believe Linux will check the default directory for the filename you specify. You have to tell it where to look, unless it's specified in your path. I know RedHat does that.

To compile C++ programs under Linux, usually you can do so with gcc. From the command line, just type "gcc <program name>" (without the quotes of course). If you need other compilation options, check out the man page, "man gcc".

Hope this helps,

its for some reason coming up w/ a compile error ive never seen before... Whats wrong with this source:
#include <iostream.h>
int main()
{
cout << "Hello, World!";
return 0;
}

A little more detail here might help. You're basically asking us to fix a leaky basement without telling us where the leak is.
What errors are you getting?

[alphabetarian]

ummm... what's the error??

[kryptonite0110]

the errors are as follows:
undefined refrence to "std::cout"
undefined refrence to "std::basic_ostream <a bunch of vars passed through this arg.>
undefined refrence to "std::iso_base::Init::~Init [in-charge]()"
undefined refrence to "__gxx_personality_v0"
and then it says:
collect2: ld returned 1 exit status

Try including the line

using namespace std;

Your code would look like this:

#include <iostream.h>
using namespace std;
int main()
{
cout << "Hello, World!";
return 0;
}

You haven't defined a nemaspace which includes the cout stream yet.
Hope this helps.

/edit
Some compilers add namespaces by default if you don't tell them to. The Gnu C compiler doens't, but it's free, so I never complain about it.
