<?php $parent = $post->ID; ?>

<?php query_posts(‘posts_per_page=15&post_type=page&post_parent=’.$parent);

while (have_posts()) : the_post(); ?>

<div>
<a href=”<?php the_permalink(); ?>” title=”<?php the_title_attribute(); ?>”>

<h4 id=”subtext”><?php the_title(); ?></h4></a>

<p> <?php the_excerpt(); ?> </p>

</div>

<?php endwhile; ?>

This creates a new Loop which gets all the subpages of the current page, displaying the title and excerpt of the subpage.

First, I installed my IDE of choice – Code::Blocks (version 8.02), available from the repositories. I’m going to assume you can get Code::Blocks set up and compiling C++ yourselves. Once that’s going, you need to link the GLUT/SDL libraries. You only really need GLUT or SDL, but I have both so I have the choice. For this, we need to download and install a few packages – namely freeglut3 and freeglut3-dev for GLUT, and libsdl1.2-dev for SDL. If you want to check out what they installed, GLUT files are installed to /usr/include/GL/, and SDL to /usr/include/SDL.

Second, we need to link CodeBlocks to the correct library files for it to be able to compile GLUT/SDL programs. Open up Code::Blocks, and click through to Settings > Compiler and debugger.., then hit the Linker settings tab. Under ‘Link libraries’, you simply need to add the values “glut” for GLUT, and “SDL“, “GLU” & “GL” for SDL.

That should be everything finished!

To give it a try, have a go running the pieces of code over on http://www.ferdychristant.com/blog/articles/DOMM-72MPPE, where I found out how to do all this!
