The project stuff is sort of an add-on for regular makefile usage - partly because at MorphOS Team we're used to launching make from console ;) Generally, the build functionality will use the makefile at your project's root directory. The root directory is determined by default when you open a .c/h/etc file. Scribble then searches in that dir for default.sprj project file and if that isn't located, it traverses parent directories. The location of default.sprj will also be used as the root for automatic C code indexation.

So, save a project as default.sprj in the location where the root of your project is and make sure there's a makefile there.
