From: pocket on 6 Jan 2010 09:48 Hello. I want to use share library in /usr/local/lib with cffi on my MacOSX 10.6 with SBCL SBCL 1.0.30 But, when I try to use share library in /usr/local/lib like this: (define-foreign-library libqrencode (:darwin "libqrencode.dylib") (t (:default "libqrencode"))) (use-foreign-library libqrencode) But, I got error: debugger invoked on a LOAD-FOREIGN-LIBRARY-ERROR: Unable to load foreign library (LIBQRENCODE). Error opening shared object "libqrencode.dylib": dlopen(3) failed. Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL. restarts (invokable by number or by possibly-abbreviated name): 0: [RETRY ] Try loading the foreign library again. 1: [USE-VALUE] Use another library instead. 2: [ABORT ] Exit debugger, returning to top level. (CFFI::FL-ERROR "Unable to load foreign library (~A).~% ~A") [:EXTERNAL] Then I try to use another library in /usr/local/lib/. But I got same error. So I try to read some existing asdf-library may be using library in / usr/local/lib. I choose cl-png this asdf-library working fine on my system and I have libpng12.dylib in /usr/local/lib Then I found define-foreign-library in cl-png like this: (define-foreign-library libpng ;; (:unix (:or "libpng12.0.dylib" "libpng12.dylib" "libpng12.so.0")) (t (:default "libpng12"))) So I try to same definition to libqrencode like this: (define-foreign-library libqrencode ;; (:unix (:or "libpng12.0.dylib" "libpng12.dylib" "libpng12.so.0")) (t (:default "libqrencode"))) But, I still get same error. I search about it but I can't get any help. What is different betwwn libpng12.dylib and libqrencode.dylib.

See http://common-lisp.net/project/cffi/manual/html_node/_002aforeign_002dlibrary_002ddirectories_002a.html Note that the OS should set this up properly, but sometimes it doesn't work on Darwin. Then try #+darwin (pushnew "/usr/local/lib/" *foreign-library-directories*) HTH, Tamas

Is it possible that this library is 64-bit only? On Mac you can have multiple-architecutures in the same .o, .dylib, elf file (called FAT, or Universal binaries). For example: malkia ~ $ lipo -info /usr/lib/libz.dylib Architectures in the fat file: /usr/lib/libz.dylib are: x86_64 i386 ppc7400 So make sure that this library is compiled for the right architecutre, and recompile it if needed. With MacPorts, usually this is enough: sudo port install somelib +universal On Jan 6, 11:14 pm, pocket <poketo7...(a)yahoo.co.jp> wrote: > On 1æ7æ¥, åå12:46, Francogrex <fra...(a)grex..org> wrote: > > > On Jan 6, 3:48 pm, pocket <poketo7...(a)yahoo.co.jp> wrote: > > > > Hello. > > > I want to use share library in /usr/local/lib with cffi on my MacOSX > > > 10.6 with SBCL SBCL 1.0.30 > > > But, when I try to use share library in /usr/local/lib like this: > > > What happens when you directly use (cffi:load-foreign-library "/usr/ > > local/lib/yourlib.so") ? > > When I try to load /usr/local/lib/libqrencode.dylib directly. > I got same error: > > * (cffi:load-foreign-library "/usr/local/lib/libqrencode.dylib") > > debugger invoked on a CFFI:LOAD-FOREIGN-LIBRARY-ERROR: >  Unable to load foreign library (NIL). >  Error opening shared object "/usr/local/lib/libqrencode.dylib": >  dlopen(3) failed. > > Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL. > > restarts (invokable by number or by possibly-abbreviated name): >  0: [RETRY   ] Try loading the foreign library again. >  1: [USE-VALUE] Use another library instead. >  2: [ABORT   ] Exit debugger, returning to top level. > > (CFFI::FL-ERROR "Unable to load foreign library (~A).~%  ~A") > [:EXTERNAL] > > Here is my backtrace in sbcl: > > 0: (CFFI::FL-ERROR "Unable to load foreign library (~A).~%  ~A") > [:EXTERNAL] > 1: (CFFI::LOAD-FOREIGN-LIBRARY-PATH NIL "/usr/local/lib/ > libqrencode.dylib") > 2: (CFFI:LOAD-FOREIGN-LIBRARY "/usr/local/lib/libqrencode.dylib") > 3: (SB-INT:SIMPLE-EVAL-IN-LEXENV >   (CFFI:LOAD-FOREIGN-LIBRARY "/usr/local/lib/libqrencode.dylib") >   #<NULL-LEXENV>) > 4: (INTERACTIVE-EVAL >   (CFFI:LOAD-FOREIGN-LIBRARY "/usr/local/lib/libqrencode.dylib")) > [:EXTERNAL] > 5: (SB-IMPL::REPL-FUN NIL) > 6: ((LAMBDA ())) > 7: (SB-IMPL::%WITH-REBOUND-IO-SYNTAX #<CLOSURE (LAMBDA #) {11885DBD}>) > 8: (SB-IMPL::TOPLEVEL-REPL NIL) > 9: (SB-IMPL::TOPLEVEL-INIT) > 10: ((LABELS SB-IMPL::RESTART-LISP)) |
