Hello Insight

Traditionally, the very first program you learn to write in any given language is the simplest code to print "Hello World!". Following in a similar vein, we hereby present the simplest possible ITK program (which also happens to print a boring message). While it doesn't demonstrate anything very sophisticated, it can be used to demonstrate that you can build programs against your freshly installed ITK, and that you can run them. If this seemingly trivial step succeeds, it means:

  1. ITK was built successfully (the build itself succeeded)
  2. ITK development files were installed successfully (and your compiler can find all the right headers and libraries)
  3. The ITK runtime is good (since your OS can find the required shared libraries and so on)

All this working is a good thing.

So without further ado, fire up your favourite text editor and get started!

Hello Insight - Really

Create a new directory. Be imaginative and call it `HelloInsight`. Create a file called `HelloInsight.cxx` therein, and enter the following code:

#include <itkImage.h>
