The Quick and Dirty "Hello World" with GCC

by Martin Iturbide

I just wanted to check out which will be the most basic example to use the gcc compiler to create on OS/2-eCS the most basic, most easy program on earth, the "Hello World" program.

First I installed with Arca Noae Package Manager the gcc compiler.

I created a simple text file called "hello.c" and included on it.

/* Hello World program */

#include<stdio.h>

main()
{
    printf("Hello World");
}

The most simple program on C to print out "Hello World" on the command prompt.

To compile it is as simple as:

gcc -o hello.exe hello.c

It will generate a "hello.exe" file.

When you run it you will see:

It can not be more simple.

The -o file parameter of gcc it is just to place the output of the compile into an specific file name.
