Hi folks, I need some help from you. What I want to do is that my main program is in R and I want to implement part of it with ocaml.
The following is an example. /* mysin.R */ dyn.load("mysin.so") mysin <- function(x) .C("mysin", as.double(x), r = double(1))$r /* mycode.ml */ let sin_ml x = sin x let _ = Callback.register "sin_ml" sin_ml I want to use sin defined in mycode.ml in mysin.R Then I write the following stub code /* mysin.c */ #include <caml/mlvalues.h> #include <caml/memory.h> #include <caml/alloc.h> #include <caml/custom.h> #include <caml/callback.h> void mysin(double * x, double * r){ value * closure_f; caml_startup(NULL); closure_f = caml_named_value("sin_ml"); *r = Double_val(caml_callback(*closure_f, caml_copy_double(*x))); } It isn't working right now. What I am not sure about is what to put in caml_startup. Can somebody help with me this? Thank you very much! Best, Peng _______________________________________________ Caml-list mailing list.
