Since they don’t provide a Guile module you need to define a module like this: --8<---cut here---start->8--- (define-module (libgv) #:export (digraph node edge layout render setv)) (load-extension "libgv_guile" "SWIG_init") --8<---cut here---end--->8--- These bindings are not very useful for anything beyond visualizing graphs, though. -- Ricardo

My example above just shows the pattern that needs to be used. Roel’s module there exports *all* the procedures. The point, however, is — as Dmitry wrote earlier — that gv does not provide any predicates or search algorithms. gv only provides constructors and accessors to the graphviz data structure, and the means to render them. -- Ricardo
