[cffi-devel] translate-to-foreign on a class
by Tamas K Papp 30 Jul '07

30 Jul '07

Hi, I have a class which is defined like this (basically, wraps a pointer): (defclass x-display () ((display-pointer :initform (null-pointer) :initarg :display-pointer :documentation "pointer to an Xlib display structure"))) For convenience, I would like to use it in place of a pointer, with some extra error checking: (defmethod translate-to-foreign (value (type (eql 'x-display))) (with-slots (display-pointer) value (when (null-pointer-p display-pointer) (error "the X11 display is not open")) display-pointer)) But this doesn't work: functions complain that they expect a system-area-pointer (I am in SBCL), so this method is not called. What am I doing wrong? Thanks, Tamas

[cffi-devel] Your approach to debug CFFI problems (segfaults)
by Christian Schuhegger 27 Jul '07

27 Jul '07

Hello together, I am trying to get running the cl-alleg library: http://cl-alleg.sourceforge.net/ But in cmucl, sbcl and clisp I either get segfaults or cause the abort handler to be called. My set-up is a recent debian lenny: Linux XXX 2.6.21.070708-1354 #1 SMP clisp 1:2.41-1 cmucl 19d-20061116-2 sbcl 1:1.0.7.0-1 slime 1:20070628-1 liballegro4.2-dev 2:4.2.0-5 cffi-070620.tar.gz I've started to write lisp-unit test cases to track down the root of the problem, but without success. I would really appreciate if you could tell me about your approach to debugging such problems. I started to modify cl-alleg a bit, because it was originally written for windows and if you would like to see which problems I am talking about you can checkout the following CVS module: > cvs -d:pserver:anonymous@sablaster.cvs.sourceforge.net:/cvsroot/sablaster login > cvs -z3 -d:pserver:anonymous@sablaster.cvs.sourceforge.net:/cvsroot/sablaster co -P project-workspace/ In project-workspace/lisp/README I've put a detailed description of how to arrive at the test situation. I would be glad about any helping hand, -- Christian Schuhegger http://www.el-chef.de/

[cffi-devel] [PATCH] emulating LONG-LONG on ECL
by Stelian Ionescu 20 Jul '07

20 Jul '07

Attached there is a patch made against the main branch(not the newtypes one) which adds :UNSIGNED-LONG-LONG and :LONG-LONG to ECL; to be more specific: 1) it adds a new feature: CFFI:EMULATED-LONG-LONG(not sure this is a good name - see the callbacks issue below) 2) it calculates at compile time the machine endianess and pushes a new feature, either :LITTLE-ENDIAN or :BIG-ENDIAN 3) %MEM-REF and %MEM-SET are renamed to %NATIVE-MEM-REF and %NATIVE-MEM-SET while the new %MEM-REF and %MEM-SET dispatch on the effective type using CANONICALIZE-FOREIGN-TYPE(which is forward-referenced but it should be ok) 4) it adds compiler macros for %NATIVE-MEM-REF and %NATIVE-MEM-SET this patch passes the DEREF.*LONG-LONG memory tests(which I ran manually since ECL seems to have some problems in running the tests) two are the problems I've encountered: 1) callbacks don't work since actually ECL doesn't have LONG-LONG. this can be "fixed" by stating in the docs that on platforms where LONG-LONG is emulated callback simply don't work. 2) although possibly not related to CFFI, when loading IOLIB-POSIX I got this: NIL is not of type REAL. Broken at CFFI::NOTICE-FOREIGN-STRUCT-DEFINITION. IOLIB-POSIX>> :backtrace Backtrace: CFFI::NOTICE-FOREIGN-STRUCT-DEFINITION > eval I'll investigate further this issue. -- (sign :name "Stelian Ionescu" :aka "fe[nl]ix" :quote "Quidquid latine dictum sit, altum videtur.")
