Hello,

i'am using the CFFI on 32-bit machines without any problem. Switching to a 64-bit platform breaks the loading of a lib.

uname -a: Linux master 2.6.8-24-smp #1 SMP Wed Oct 6 09:16:23 UTC 2004 x86_64 x86_64 x86_64 GNU/Linux

/etc/SuSE-release: SuSE Linux 9.2 (x86-64) VERSION = 9.2

sbcl: SBCL 0.9.11

library: libgslcblas.so.0 (libc6,x86-64) => /usr/lib/libgslcblas.so.0 libgslcblas.so (libc6,x86-64) => /usr/lib/libgslcblas.so libgsl.so.0 (libc6,x86-64) => /usr/lib/libgsl.so.0 libgsl.so (libc6,x86-64) => /usr/lib/libgsl.so

; alternative 1 (define-foreign-library libgslcblas (:unix (:or "libgslcblas.so.0.0.0" "libgslcblas.so.0")) (t (:default "libgslcblas"))) ; alternative 2 (define-foreign-library libgslcblas (t (:default "libgslcblas")))

(use-foreign-library libgslcblas) <---the error happens here

(define-foreign-library libgsl (:unix (:or "libgsl.so.0.9.0" "libgsl.so.0")) (t (:default "libgsl"))) (use-foreign-library libgsl)

;;;; (defcfun "gsl_sf_bessel_J0" :double (x :double)) (time (format t "~A~%" (gsl-sf-bessel-J0 5d0))) ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; END

The error message: Unable to load foreign library: libgslcblas.so [Condition of type LOAD-FOREIGN-LIBRARY-ERROR] 0: (CFFI::HANDLE-LOAD-FOREIGN-LIBRARY-ERROR "libgslcblas.so" "Unable to load foreign library: ~A" "libgslcblas.so")

It doesn't matter if i use alternative 1 or 2.

Is it a general matter that CFFI cannot handle 64-bit libs ?
