From: Paul Varoutsos Date: 2009-03-15T03:24:01+09:00 Subject: new to ruby: uninitialized constant I have a program the simulates the knights tour problem. I made 2 classes, 1 called 'Location' which simulates a location on a chess board and one called 'KnightsTour' which actually performs the knights tour. Then I have a main.rb file which just creats a knights tour object (KnightsTour.new) and calls a method on that object. But whenever i try to run it, I get the following error: C:\NetBeansWorkspace\KnightsTour\lib\main.rb:3:in `const_missing': uninitialized constant KnightsTour (NameError) from C:\NetBeansWorkspace\KnightsTour\lib\main.rb:8 Any help would be greatly appreciated. -- Posted via http://www.ruby-forum.com/.
