Adding E before the DT to get rid of that error, then commenting out the unnecessary line of code that caused the remaining error, still didn't work because it was trying to link to the old Irrlicht.dll.Seamless World & Repeating Seamless words
Two other tutorials by Saigumi which show how to create seamless worlds and repeating seamless worlds with Irrlicht. Quite interesting.
These tutorials would be used most by new users, but you can no longer even download the older version necessary to run them, thus making them rather useless.
Perhaps all the writers, or someone else even, can get around to updating them.
