There is no such restriction and there are actually several plug-ins which refer to module File. Are you sure that you have no other module File somewhere in your linked code which hides the kernel one? > Anyway, I replaced the call to "File.create_project_from_visitor" by one > to "Project.create_by_copy" and it seems to work all right, but I'm not > quite sure there's no difference between the two? File.create_project_from_visitor internally uses Project.create_by_copy. The latter only creates a new project which is a copy of its argument. The former performs the same operation, but (1) it also applies the provided visitor in order to modify the AST and (2) it reset some Frama-C states to keep Frama-C consistent as a whole. Hope this helps, Julien
