[FLASH-USERS] Newbie Question: Adding Variables

[John ZuHone]

Hi Henry,

Just a quick question first--had you compiled this code first in an object directory and you're trying to recompile after making these changes? If you add anything to the Config file you need to re-setup the code in this directory first, which you can do by issuing "./resetup" within the object directory, after which you can recompile. 

Best,

John
