Hi,

some more stupid questions:

What causes a variable being global (accessible by all recipes)?
Does the declaration in *.conf lead to global variable?
Are there other mechanisms forcing global scope?

Thanks in advance

Andreas

Maybe my intention was not clear. For a generic run-once
implementation (see patch for gtk-icon-cache.bbclass [1]) I need
variables which are shared by all recipes. Each recipe can append data
so the 'sum' is used at image creation. What steps are necessary
creating a variable which is existing as one instance for all recipes
using it?

There are no steps, because there is no support for such a thing.
