in using the guile FFI I am having a segmentation fault
This is the C unction that I'm trying to wrap
https://www.gaia-gis.it/gaia-sins/freexl-1.0.1-doxy-doc/html/freexl_8h.html#acbd27ba5bc7b21d4ae32c0542d51f1e4
My code is here
https://gitlab.com/humanitiesNerd/guile-freexl
(configure is to be called with --with-freexl-libdir=... otherwise it won't
work)
Here's an excerpt
(define freexl-open
(let* ((ptr (freexl-func "freexl_open"))
(proc (pointer->procedure int ptr '(* *)))
;;const char *path, const void **xls_handle
)
(lambda (path)
(let ((handle (scm->pointer 0))
(path-ptr (string->pointer path)))
(proc path-ptr handle)))))
At the REPL, when calling it with
> (freexl-open"resources/Lavoro_P.xsl")
it produces a segmentation fault
probably this line
(scm->pointer 0)
is not correct
But I don't know how to produce a void pointer and then pass it to
freexl-open
Thanks in advance
