Hello,
I'm new to this list (and new to Lisp) and I just wanted to try to call
ECL from VASmalltalk - all I want to execute here
is stuff like (posted 2009 on this list):
int main(int argc, char **argv)
{
cl_object form, result;
cl_object princed;
cl_object g_eclEvalErrorSymbol;
cl_boot(argc, argv);
form = c_string_to_object("(+ 1 1)");
result = si_safe_eval(3, form, Cnil, g_eclEvalErrorSymbol);
princed = cl_princ_to_string(1, result);
printf("output: %s\n",(char *)princed->base_string.self);
cl_shutdown();
return (0);
}
but I have several problems here:
* first I have only the DLL available, therefore I can not use macros, but
only exported functions from ecl.dll
* cl_princ_to_string(1, result) has only one argument and NOT two
* how can I get the result "2" as a string via function calls
what I have done so far is executing code (ok, from smalltalk to ecl) like:
cl_boot(argc, argv);
result = si_safe_eval(3, ecl_make_simple_base_string("(+ 1 1)",-1), Cnil,
OBJNULL);
char* myString =
ecl_base_string_pointer_safe(si_copy_to_simple_base_string(cl_princ_to_string(result)))
cl_shutdown();
and the content of myString is then: "(+ 1 1)", but I would like to get "2"
...... :-(
and two other problems/questions I have:
* where is the cl_object definition located .... seems to be strange for you,
but I was not able to find the location of the definition
* when trying to create ecl under Windows - my anti virus software named
antivir complains, that the newly created dpp.exe has a virus. Therefore
I have to turn off the antivirus software, create the stuff and then
turn it on again.
