[cffi-devel] how to debug CFFI:LOAD-FOREIGN-LIBRARY-ERROR
by Tamas K Papp 21 Apr '08

21 Apr '08

Hi, After recently upgrading my Cairo deb packages, I am getting this error message when tryign to load the library via CFFI: Unable to load foreign library (NIL). Error opening shared object "libcairo.so": /usr/lib/libcairo.so: undefined symbol: pixman_format_supported_destination. [Condition of type CFFI:LOAD-FOREIGN-LIBRARY-ERROR] Restarts: 0: [RETRY] Try loading the foreign library again. 1: [USE-VALUE] Use another library instead. 2: [RETRY] Retry performing #<ASDF:LOAD-OP NIL {AFF2349}> on #<ASDF:CL-SOURCE-FILE "cairo" {AFD70B9}>. 3: [ACCEPT] Continue, treating #<ASDF:LOAD-OP NIL {AFF2349}> on #<ASDF:CL-SOURCE-FILE "cairo" {AFD70B9}> as having been successful. 4: [ABORT] Return to SLIME's top level. 5: [TERMINATE-THREAD] Terminate this thread (#<THREAD "worker" {B4A26A1}>) Backtrace: 0: (CFFI::FL-ERROR "Unable to load foreign library (~A).~% ~A") 1: (CFFI::LOAD-FOREIGN-LIBRARY-PATH NIL "libcairo.so") 2: (CFFI:LOAD-FOREIGN-LIBRARY (:DEFAULT "libcairo")) Before filing a bug report, I would like to find out what this means (I am pretty clueless about shared libraries). Does it mean that someone who compiled a library made a mistake, or should I load another library with this symbol in CFFI, etc. Sorry for the dumb question, but I don't know where to start. Tamas

[cffi-devel] problem with translation to foreign types
by Tamas K Papp 21 Apr '08

21 Apr '08

Hi, I have a problem getting automatic type translation to work. In my cl-cairo2 package (http://www.cliki.net/cl-cairo2), some cairo functions expect booleans, but I want them to work with integers etc. I set up a translate-to-foreign method as described in the manual, and was using it, but recently it stopped working, in the sense that translate-to-foreign still works when called manually, but functions don't seem to call it (they did before, I changed nothing), and when trying to check with convert-to-foreign, that does not work either. I reduced my problem to a small, clean example: (require :cffi) (cffi:defctype my-double :double) (defmethod cffi:translate-to-foreign (value (type (eql 'my-double))) (coerce value 'double-float)) (cffi:translate-to-foreign 10 'my-double) ; => 10d0 (cffi:convert-to-foreign 10 'my-double) ; => 10, should be 10d0! What am I doing wrong? Thanks, Tamas PS: cl-cffi 20080217-1, sbcl 1:1.0.14.0-1.

[cffi-devel] Casting
by christopher melen 20 Apr '08

20 Apr '08

Hi, I've generated a set of CFFI bindings for FFTW (http://www.fftw.org). FFTW has its own versions of malloc and free (fftw_malloc, fftw_free). So for example, one would do (where fftw_complex is a specific FFTW type) - fftw_complex *in; in = (fftw_complex*) fftw_malloc(sizeof(fftw_complex) * N); There is a rudimentary set of SBCL bindings for FFTW which binds the above in the following way - (defun fftw-malloc-complex (size) (sb-alien:cast (fftw::|fftw_malloc| (* *sizeof-fftw-complex-in-bytes* size)) (* fftw::|fftw_complex|))) My question is: how do I cast using CFFI? Thanks, Chris __________________________________________________________ Sent from Yahoo! Mail. A Smarter Email http://uk.docs.yahoo.com/nowyoucan.html

[cffi-devel] LispWorks 5.0/5.1 and LONG-LONG support
by Chun Tian (binghe) 07 Apr '08

07 Apr '08

Hi, dear CFFI Developers Since LispWorks 5.1 has been released yesterday, I can start to talk about it. * :long-long and :unsigned-long-long support LispWorks 5.0 64-bit can already support :long-long and :unsigned-long- long, but the FLI:FOREIGN-TYPED-AREF function cannot support them, and, LispWorks 5.1 64-bit has fixed this, now FLI:FOREIGN-TYPED-AREF can support 64-bit integers. * LispWorks *features* Though LispWorks cannot use a >=version like compile feature like those in Allegro, but since LW is very stable and its version grows very slowly (0.1/year ^_^), I think we can use #+(and lispworks-64bit (not lispworks5.0)) to mean "LispWorks 64-bit version >= 5.1" I attach a simple patch, which opens the 64-bit integer support on LW 5.0 & 5.1 (64-bit). Hope it can be reviewed and merged into CFFI trunk. I'll always need these changes to compile & load IOLIB project on 64-bit LispWorks. Regards, Chun Tian (binghe)

[cffi-devel] CLISP no longer supports ffi::foreign-library-function
by Barry Fishman 05 Apr '08

05 Apr '08

As of (From the CLISP src/Changelog): 2006-10-05 Sam Steingold <sds(a)podval.org> merged LOOKUP-FOREIGN-FUNCTION & FOREIGN-LIBRARY-FUNCTION into FIND-FOREIGN-FUNCTION; LOOKUP-FOREIGN-VARIABLE & FOREIGN-LIBRARY-VARIABLE into FIND-FOREIGN-VARIABLE ... This includes CVS releases starting with clisp-2.41. FFI::FOREIGN-LIBRARY-FUNCTION and FFI::FOREIGN-LIBRARY-VARIABLE have effectively been made legasy. In the current CVS head (but not the last clisp-2.44.1 release) these functions have quietly disappeared. This causes problems with the CLISP CVS head in cffi-clisp.lisp. I'm not sure what version of CLISP need to be supported. Should the new FFI::FIND-FOREIGN-FUNCTION and FFI::FIND-FOREIGN-VARIABLE interface now be used. -- Barry Fishman
