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.
