Thanks for testing this. It was very helpful. Using your program I got the library working on Racket 5.2.1.6 but not on 5.3.0.6.
In mzgsl/low-level/gsl-lib.rkt I had to make sure CBLAS was loaded in GLOBAL mode. That is, in https://github.com/noelwelsh/mzgsl/blob/master/low-level/gsl-lib.ss I changed (define libgslcblas (ffi-lib cblaslibpath)) to (define libgslcblas (ffi-lib cblaslibpath #:global? #t)) Now I get this transcript using your test program: $ /Applications/Racket\ Full\ v5.2.1.6/bin/plt-r6rs proof.sps #(2.0 2.0 2.0) 2.0 3.0 2.0 $ /Applications/Racket\ Full\ v5.3.0.6/bin/plt-r6rs proof.sps Segmentation fault: 11 Note that prior to this I reinstalled GSL with this command: sudo port install gsl +universal whether this made any change I do not know. /Jens Axel ____________________ Racket Users list: http://lists.racket-lang.org/users
