[cffi-devel] cffi:load-foreign-library error on Clozure Cl
Hi, I am not able to load any dll library using the cffi:load-foreign-library function. I have tried using working dlls libcairo.dll, zlib1.dll, .. all of which have been working perfectly in other softwares. I have tried using win32 as well as win64 versions. This is the trace: Unable to load foreign library (LIBRARY-205). Error opening shared library libpng14-14.dll : %1 is not a valid Win32 application. . [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 SLIME REPL evaluation request. 3: [*ABORT] Return to SLIME's top level. 4: [ABORT-BREAK] Reset this thread 5: [ABORT] Kill this thread Backtrace: 0: (CFFI::FL-ERROR "Unable to load foreign library (~A).~% ~A" #:LIBRARY-205 "Error opening shared library libpng14-14.dll : %1 is not a valid Win32 application. .") 1: ((:INTERNAL CFFI::%DO-LOAD CFFI::%DO-LOAD-FOREIGN-LIBRARY) #<CFFI:FOREIGN-LIBRARY #x210144BFED> #:LIBRARY-205 "libpng14-14.dll") 2: (CFFI:LOAD-FOREIGN-LIBRARY "libpng14-14.dll" :SEARCH-PATH NIL) 3: (CCL::CALL-CHECK-REGS CFFI:LOAD-FOREIGN-LIBRARY "libpng14-14.dll") 4: (CCL::CHEAP-EVAL (CFFI:LOAD-FOREIGN-LIBRARY "libpng14-14.dll")) 5: (SWANK::EVAL-REGION "(cffi:load-foreign-library \"libpng14-14.dll\")\n") 6: ((:INTERNAL SWANK::REPL-EVAL)) 7: (SWANK::TRACK-PACKAGE #<CCL:COMPILED-LEXICAL-CLOSURE (:INTERNAL SWANK::REPL-EVAL) #x21012B1FEF>) 8: (SWANK::CALL-WITH-RETRY-RESTART "Retry SLIME REPL evaluation request." #<CCL:COMPILED-LEXICAL-CLOSURE (:INTERNAL SWANK::REPL-EVAL) #x21012B206F>) 9: (SWANK::CALL-WITH-BUFFER-SYNTAX NIL #<CCL:COMPILED-LEXICAL-CLOSURE (:INTERNAL SWANK::REPL-EVAL) #x21012B20AF>) 10: (SWANK::REPL-EVAL "(cffi:load-foreign-library \"libpng14-14.dll\")\n") 11: (CCL::CALL-CHECK-REGS SWANK:LISTENER-EVAL "(cffi:load-foreign-library \"libpng14-14.dll\")\n") 12: (CCL::CHEAP-EVAL (SWANK:LISTENER-EVAL "(cffi:load-foreign-library \"libpng14-14.dll\")\n")) 13: (SWANK:EVAL-FOR-EMACS (SWANK:LISTENER-EVAL "(cffi:load-foreign-library \"libpng14-14.dll\")\n") "COMMON-LISP-USER" 38) 14: (SWANK::PROCESS-REQUESTS NIL) 15: ((:INTERNAL SWANK::HANDLE-REQUESTS)) 16: ((:INTERNAL SWANK::HANDLE-REQUESTS)) 17: (SWANK-BACKEND:CALL-WITH-DEBUGGER-HOOK #<Compiled-function SWANK:SWANK-DEBUGGER-HOOK #x21007251EF> #<CCL:COMPILED-LEXICAL-CLOSURE (:INTERNAL SWANK::HANDLE-REQUESTS) #x2100AB3BEF>) 18: (SWANK::CALL-WITH-BINDINGS ((*STANDARD-OUTPUT* . #<SWANK-BACKEND::SLIME-OUTPUT-STREAM #x2100AB2A7D>) (*STANDARD-INPUT* . #<SWANK-BACKEND::SLIME-INPUT-STREAM #x2100AB2E3D>) ..))) #<CCL:COMPILED-LEXICAL.. 19: (SWANK::HANDLE-REQUESTS #<CONNECTION #x210099BC7D> NIL) 20: (CCL::RUN-PROCESS-INITIAL-FORM #<PROCESS repl-thread(10) [Active] #x2100AA1CCD> (#<CCL:COMPILED-LEXICAL-CLOSURE (:INTERNAL CCL::%PROCESS-RUN-FUNCTION) #x2100AA1A6F>)) 21: ((:INTERNAL (CCL::%PROCESS-PRESET-INTERNAL (CCL:PROCESS))) #<PROCESS repl-thread(10) [Active] #x2100AA1CCD> (#<CCL:COMPILED-LEXICAL-CLOSURE (:INTERNAL CCL::%PROCESS-RUN-FUNCTION) #x2100AA1A6F>)) 22: ((:INTERNAL CCL::THREAD-MAKE-STARTUP-FUNCTION)) Should it be 'cause I am using x64 version of Clozure Cl ?

Hm - never seen this particular kind of error message but the nature of it points to a problem finding the DLL. Where is libpng14-14.dll located? What does cffi:*foreign-library-directories* say? Also, you could use (load-foreign-library '( :default "libpng14-14" )) to load the DLL.

Most probably not. Hope that helps. Frank

No, it points to a problem of x64 vs. 32-bit mismatch (the library is found, but it's impossible to load it). -- Regards, Anton Kovalenko <http://github.com/akovalenko/sbcl-win32-threads/wiki> +7(916)345-34-02 | Elektrostal' MO, Russia
