How to compile program in Emacs

[Rob k]

Hi guys,

Struggling a little here, I have a mac and am using emacs, but I can't seem to compile my program, I have tried
M-x compile
make -k

and that returns an error 2 code.

so I tried
g++ -o hello helloworld.cpp

and that returns an error 1 code.

How do I compile my programs so I can start programming please? Is there not just a simple way to compile in emacs.

Kind regards
Rob

For anyone finding this thread, I have solved my problem, the problem was in my simple hello world program, the one I tried to compile was:

#include <iostream>

int main()
{
     std::cout << "Hello World!" << std::endl;
    return o;
}

the return o should have been the number zero not the letter o. Silly typo, but it's fixed now.

Note to self, check syntax when setting up your environment.

Kind regards
Rob
