[cffi-devel] Weird segfaults interfacing with libsane
by Rupert Swarbrick 12 Jun '08

12 Jun '08

Hi there, I'm trying to use cffi to write some bindings for libsane. Having quite some success, but for the following (rather bizarre) problem. libsane expects: sane_init(), do some stuff, sane_exit() but when I call sane_exit after having done anything non-trivial (for example, called sane_get_devices), sbcl segfaults and dies. I realise that that's not the sort of question for the cffi list, _but_ I wrote a trivial C program that I think should be equivalent and it doesn't die. I can't work out *how* libsane can work in one case and not the other (!) so I was wondering if anyone could make any suggestions. I'm attaching the two source files here. The other piece of information is that I asked about this on #lisp a few minutes ago, and hefner very kindly tested it out, with no segfault at his end. I've had the same symptom with both the asdf-installed cffi and the darcs lotsastuff branch. I presume there's an error somewhere in my libsane config which explains why it's dying, but I'm hoping that someone can explain how it can fail in the lisp program and not in the C one. Oh, it's linux i386 with SBCL from CVS this evening. Thanks, Rupert

[cffi-devel] CFFI::SYMBOLICATE undefined
by Chun Tian 12 Jun '08

12 Jun '08

Hi, CFFI developers I'm testing CFFI on this darcs url: http://common-lisp.net/project/cffi/darcs/cffi When I compiled CFFI, CMUCL and LispWorks both tell me: function CFFI::SYMBOLICATE is undefined in macro CFFI:DEFCVAR in file src/foreign-vars.lisp. Is this a bug? P.S. In LispWorks, I found this function in LW's system package: SYSTEM:SYMBOLICATE, I don't know if this function can be used. Regards, Chun Tian (binghe)

[cffi-devel] Foreign struct
by Liam Healy 11 Jun '08

11 Jun '08

I'm having a problem defining/using a foreign struct for my package GSLL (http://common-lisp.net/project/gsll), an interface to the GNU Scientific Library (http://www.gnu.org/software/gsl/), written in C. I am trying to handle complex numbers; GSL has a struct defined to represent complex numbers in /usr/include/gsl/gsl_complex.h: typedef struct { double dat[2]; } gsl_complex; So I define (cffi:defcstruct complex-double-c (dat :double :count 2)) I set this value with a function (defun complex-to-gsl-df (number) (let* ((gsl (cffi:foreign-alloc 'complex-double-c)) (datslot (cffi:foreign-slot-pointer gsl 'complex-double-c 'dat))) (setf (cffi:mem-aref datslot :double 0) (realpart number) (cffi:mem-aref datslot :double 1) (imagpart number)) gsl)) When I pass a complex number generated with this function to a GSL function, I always get the following result: the real part is what I specified for the imaginary part, and the imaginary part is the number 5.2635442471208903e-315, which I discovered is the single-float number -1.0f0 interpreted as a double float (I don't know if that's significant). So for example the function #'test-set-all should set every element of the complex vector to the same number 3+4i, but I get 4+5.2635442471208903e-315i: (letm ((intvec (vector-complex-double-float 2))) (test-set-all intvec #c(3.0d0 4.0d0)) (maref intvec 1)) #C(4.0 5.2635442471208903e-315) There is a GSL function that sets the real and imaginary parts of the struct (in C of course). When I use this, I get the answer I expect. Unfortunately, it's more restricted than setting the structure in CL, so I'd like to solve the structure problem. My platform is SBCL 0.9.16, amd64 Debian (stable). I have a feeling I have misinterpreted the defcstruct usage. Any ideas? Thanks, Liam

[cffi-devel] make-shareable-byte-vector in LispWorks 5.1
by Chun Tian (binghe) 10 Jun '08

10 Jun '08

Hi, CFFI developers There's another change from LispWorks 5.1's static array allocation: Instead of (sys:in-static-area (make-array 3 :element-type '(unsigned-byte 8) :initial-contents '(65 77 23))) We use this now: (make-array 3 :element-type '(unsigned-byte 8) :initial-contents '(65 77 23) :allocation :static) see http://www.lispworks.com/documentation/lw51/FLI/html/fli-130.htm#pgfId-1112… I hope the patch in attach can be merged. Thanks.
