Hi listers,
I'm having a problem finding a primitive function in one of my
modules. Here is the setup. I have a C program which (after
booting guile) defines a routine a-la:
scm_c_define_gsubr("dvect?", 1, 0 ,0, dvect_p);
Then the program loads a file using
scm_c_primitive_load("root.scm");
At the top of root.scm I include a module via: (use-modules (slab)) Now
within the text of the slab.scm I expect to use dcect?. However, the guile
cannot reference dvect? -- it can't find it. The problem is that dvect? is
being put in the (guile-user) module. And the slab module can't see it.
I've tried to (use-modules (guile-user)) and this seems to have no effect.
Does anyone have any ideas how I can get it so that the slab module can
see dvect? ?
Thanks for any help,
Pete

I had similar problems trying to make a program compatible with both guile-1.5/1.6 and guile-1.4 - one of the differences between the two is which module C primitives end up in vs. the default module that scheme code runs in. I came up with this hack, placed immediately after initializing guile and before defining primitives to make guile-1.6 behave enough like 1.4: #ifdef HAVE_SCM_C_READ_STRING { SCM exp = scm_c_read_string("(define-module (guile))"); scm_primitive_eval_x(exp); } #endif While this works, making guile 1.6 behave like 1.4 isn't really the way to go any longer. I see that the guile-1.6.4 reference manual has a nice section "Accessing Modules from C." (thanks authors!) When writing a program for guile >= 1.6 only, it appears that one should use scm_c_define_module() to place their C primitives into the desired application-specfic module.

Christopher @ 2003-07-26 18:03 UTC (permalink / raw) Cc: guile-user Hi there, Thanks for the help Steve, worked like a charm. For the benefit of anyone who is interested: here is how one defines primitives in the (guile) module (rather than the (guile-user) module which seems to be standard). <CODE> SCM slab_write_sloppy(); SCM slab_read_sloppy(); SCM map_globals(); SCM dvect_p(); void init_my_proc(void *data){ scm_c_define_gsubr("slab-write-sloppy", 5, 0 ,0, slab_write_sloppy); scm_c_define_gsubr("slab-read-sloppy", 4, 0 ,0, slab_read_sloppy); scm_c_define_gsubr("map-globals", 1, 0 ,0, map_globals); scm_c_define_gsubr("dvect?", 1, 0 ,0, dvect_p); return; } static void inner_main (void *closure, int argc, char **argv){ /*VARIABLES AND WHAT NO*/ // This call makes the "guile" module the current-module for the // duration of the call to init_my_proc scm_c_define_module("guile", init_my_proc, NULL); /*Etcetera*/ } </CODE> Thanks again.
