[cffi-devel] Problems with ECL+CFFI
by Tomi Neste 08 Dec '06

08 Dec '06

I have run into some problems with the cffi-061116 tarball and cvs ECL. When trying to load the cffi-examples I get 'The variable CFFI-SYS::ARG-VALUES is unbound.' error. It looks like a typo(?) in cffi-ecl.lisp: PRODUCE-FUNCTION-POINTER-CALL. After fixing that the examples compile fine but trying any of the them gives errors like '"gethostname" is not of type SI:FOREIGN-DATA.' -------------------- T. Neste

[cffi-devel] cmucl callback patch

Following patch lets cffi callbacks survive saving/loading a core on CMUCL, tested on 19dpre2 (also works on 19c with (pushnew #'system::reinitialize-global-table ext:*AFTER-SAVE-INITIALIZATIONS*) not sure if that is something cffi should do for 19c or not though) diff -rN -u old-cffi/src/cffi-cmucl.lisp new-cffi/src/cffi-cmucl.lisp --- old-cffi/src/cffi-cmucl.lisp 2006-11-12 03:27:51.000000000 -0600 +++ new-cffi/src/cffi-cmucl.lisp 2006-11-12 03:27:51.000000000 -0600 @@ -320,6 +320,18 @@ (error "Undefined callback: ~S" name)) pointer)) +;;; cmucl makes new callback trampolines when it reloads, so we need to +;;; update cffi's copies +(defun reset-callbacks () + (loop + for k being the hash-keys of *CALLBACKS* + do (setf (gethash k *callbacks*) + (alien::symbol-trampoline (cffi-sys::intern-callback k))))) + +;;; needs to be after cmucl's restore-callbacks, so put at the end... +(setf ext:*after-save-initializations* + (append ext:*after-save-initializations* (list 'reset-callbacks))) + ;;;# Loading and Closing Foreign Libraries ;;; Work-around for compiling ffi code without loading the

[cffi-devel] :string and external formats
by David Lichteblau 16 Nov '06

16 Nov '06

Hi, in the mailing list archives, I found some discussion of external format support for :string types. What is the recommended way to define a `utf8-string' type currently? Do I have to write my own foreign type translator? Thanks, David

[cffi-devel] CFFI + gtkairo + sbcl 0.9.18
by C Y 12 Nov '06

12 Nov '06

I'm not sure if this is really a CFFI issue or not, but when I'm trying to use the gtkairo backend for McCLIM (which uses CFFI) I get the following: * (clim-demo::run-test 'clim-demo::demodemo) debugger invoked on a SIMPLE-ERROR in thread #<THREAD "initial thread" {B28F279}>: Trying to access undefined foreign variable "_gdk_error_warnings". Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL. restarts (invokable by number or by possibly-abbreviated name): 0: [ABORT] Exit debugger, returning to top level. (CFFI::FOREIGN-SYMBOL-POINTER-OR-LOSE "_gdk_error_warnings") 0] Is this a CFFI issue? Cheers, CY __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
