I get a different error, but it is likely to be caused by the same problem: the compiler "optimizes" the compiled procedure for `CHICKEN_get_error_message' into a "leaf routine" (which uses different calling conventions than normal procedures). I have disabled this optimization for all external callback procedures, since the calling convention may not change in this case.

Is there any particular reason to use define? Sorry, I don't fully understand what you are trying to say. You can only call procedures from outside of Scheme which are defined with `define-external'. > > FYI, I'm trying to call Chicken commands from Python using Cython. > Interesting idea. Keep us informed about your progress, please. cheers, felix _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
