Welcome to the hierarchy-builder FAQ

  • I'm getting "Error: unable to graft this clause: no clause named compress:begin"

    You need to require HB before other files using it. From HB Require Import structures. should be the first line of every file. (This error should be gone with Coq-Elpi >= 1.10.x)

  • "Error: elpi: split-at run out of list items"

    Precise the types of the parameters and possibly add #[key(T)] attribute.

  • I'm getting "Error: You must declare the current class indt «axioms_» before indt «Blah.axioms_»"

    You might need to amend your hierarchy with an explicit join. For a concrete illustration, see this issue. See also this dedicated page.
