Here we go again After successfully wrapping freexl_open, I can't do the same with freexl_get_info One of the arguments expected by such function is "unsigned short" When I load the namespace at the REPL I get scheme@(guile-user)> ,m (freexl common) While executing meta-command: ERROR: In proce

Re: segmenation fault

It's something like (bytevector->pointer (make-vector)) there is a make-double-pointer procedure in guile git Le 9 juin 2017 9:47 AM, "Thomas Danckaert" a écrit : > From: Catonano > Subject: segmenation fault > Date: Fri, 9 Jun 2017 09:21:35 +0200 > > probably this line >> (scm->pointer 0) >>

Re: segmenation fault

From: Catonano Subject: segmenation fault Date: Fri, 9 Jun 2017 09:21:35 +0200 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 It seems you need a void ** (pointer to void pointer). I'm not familiar with Guil
