I want to use a custom makefile for my project. According to the FAQ I need to change Build Method to use makefiles in the Compiler Settings (tab Other). But I can't change it. It says Invoke Compiler Directly and won't give me any other choise (I can't open the drop-down menu since it's disabled). What do I need to do in order to get it to work?
EDIT: Oh, I forgot to tell you that I'm using Windows XP.
