[cffi-devel] CLISP no longer supports ffi::foreign-library-function
As of (From the CLISP src/Changelog): 2006-10-05 Sam Steingold <sds@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

The attached patch should fix that while maintaining backwards compatibility. Unfortunately, CVS CLISP (my copy of the ChangeLog says 2008-03-25) dumps core on the callback tests. I'm using x86-64.

Thank you. My cl-opengl code now works.

Luckly enough, my system dual boots to Ubuntu. After bringing my stuff up to date, I tried building the latest CVS CLISP there, and when I did a "make test" on CLISP, I got, on its callback test, the message and core dump you had seen. Then I remembered that another change in CLISP is to seperately package the FFCALL interface. Although Ubuntu comes with these libraries, they don't seem to work. I rebuild the libraries from the CVS repository: Repository: :pserver:anonymous@cvs.sv.gnu.org:/sources/libffcall Root: ffcall After patching CLISP's make file to use the CVS version of these libraries, everything worked fine. -- Barry Fishman

Yes, that was it. Thanks! -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/
Oops, I left off the actual test result: Test DEFCFUN.VARARGS.DOCSTRINGS failed Form: (DOCUMENTATION 'SPRINTF 'FUNCTION) Expected value: "sprintf docstring" Actual value: NIL. Also: $ clisp -q -norc [1]> (setf (documentation 'bozo 'function) "bozo docstring") NIL [2]> (documentation 'bozo 'function) NIL [3]> (defun foo (a b) "foo docstring" (+ a b)) FOO [4]> (documentation 'foo 'function) "foo docstring" [5]> (setf (documentation 'foo 'function) "changed foo docstring") "changed foo docstring" [6]> (documentation 'foo 'function) "changed foo docstring" [7]> -- Barry Fishman

Interesting, this is what makes this particular test fail though: $ clisp -q -norc [1]> (defmacro foo () "docstring" nil) FOO [2]> (documentation 'foo 'function) "docstring" [3]> (compile 'foo) FOO ; NIL ; NIL [4]> (documentation 'foo 'function) NIL -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/
