Hi,
I am trying to figure out how to use g-wrap. So far I have hacked the
examples from the documentation into the following minimal sample:
(use-modules (oop goops))
(use-modules (g-wrap))
(use-modules (g-wrap guile))
(use-modules (g-wrap guile ws standard))
(define-class <my-wrapset> (<gw-guile-wrapset>)
#:id 'my-wrapset
#:dependencies '(standard))
(define-method (initialize (ws <my-wrapset>) initargs)
(next-method)
(wrap-function! ws
#:name 'strfry
#:returns '(mchars caller-owned)
#:arguments '(((mchars caller-owned) s))
#:c-name "strfry"))
(generate-wrapset 'guile 'my-wrapset "my-wrapset")
This mostly works, but to make it compile I have to edit the generated
source to have it #include <string.h>. (Btw, if you try this example you
need to also compile with -D_GNU_SOURCE, since strfry is a GNU extension.)
How do I tell g-wrap to put "#include <string.h>\n" in the output? There
are some places in the output source where it looks like it is doing
something similar, but I couldn't figure it out.
cheers,
John
