Hi,
I am bringing my swigged Gtk2 + guile 1.8.8 + guile-gtk application up to date
and I'd like some help please.
My SWIG usage wraps many function, including enhanced_coot_ligand_p(). I am
confused between the difference between
functions that are available from C/C++ and those from a scheme script:
if my inner_main looks like this:
void inner_main(void *closure, int argc, char **argv) {
SWIG_init();
std::string handler_string = "(lambda (key . args) ";
handler_string += "(display (list \"Error in proc:\" key \" args: \" args))
(newline))";
SCM handler = scm_c_eval_string(handler_string.c_str());
std::string thunk_str = "(lambda() (display (list 444444444444444444
(enhanced-ligand-coot-p))) (newline))\n";
SCM thunk = scm_c_eval_string(thunk_str.c_str());
scm_catch(SCM_BOOL_T, thunk, handler);
gtk_main();
}
then I get on the terminal what I expected:
(444444444444444444 #f)
(i.e. enhanced-ligand-coot-p is evaluated)
if my inner_main looks like this:
void inner_main(void *closure, int argc, char **argv) {
SWIG_init();
std::string handler_string = "(lambda (key . args) ";
handler_string += "(display (list \"Error in proc:\" key \" args: \" args))
(newline))";
SCM handler = scm_c_eval_string(handler_string.c_str());
std::string thunk_str = "(use-modules (test-embedding))\n"; ////////////
different ///////////////
SCM thunk = scm_c_eval_string(thunk_str.c_str());
scm_catch(SCM_BOOL_T, thunk, handler);
gtk_main();
}
then I get:

(display "------------------- test embedding! -----------------------\n")
(display (list 55555555555555 (enhanced-ligand-coot-p)))

So, inner_main() knows that enhanced-ligand-coot-p is available, but the scheme
script does not. I don't know how to
resolve this.
How do I get a list of the available functions?
Thanks in advance for your help.
Paul.
