This chapter used to describe Prolog utilities for generating glue
code for the Foreign Language Interface (see Interface Predicates). As of SICStus 3.9, this is only supported using the
splfr tool (see The Foreign Resource Linker).
You can invoke splfr (as well as spld) with the flags
--verbose and --keep, in addition to the ordinary
arguments. This way you can see what is going on and you can also access
any generated files. The steps performed by splfr and the files
generated will change between releases so you should avoid depending on
it. If, for some reason, splfr is not suitable for your purposes
you should contact SICStus Support.
