> As a Gambas project (i.e. when you run it from the command line like you
> did), it has its own dependencies like any other Gambas project.
>
> But as a component, it has other dependencies, explicitely defined in
> the "component properties dialog" in the IDE, that are written in the
> ".component" project file.
>
> These dependencies are the source of our problems:
>
> 1) Some of them are supported by the system packager: when a component
> needs explicitely another component.
>
> 2) Some of them are not: when a component needs "a gui toolkit", or
> "saving and loading images", which means one component among all being
> able to fulfill the requirement.
>
> These kind of dependencies are not solved at package level, but only
> when creating the final project, that will only have explicit
> dependencies of single packages (i.e. the requirements of second type
> are solved by the IDE when checking the components in the project
> property dialog).
>
> Moreover, not all of them are solved: 'gb.gui' and 'gb.desktop', as you
> noticed.

Okay, so I'm going to rewrite them.

> You're right, all components should logically depend on gambas3-runtime.

I just asked because otherwise I get a warning when packing these 
components.
