Dmitry, Thanks a lot for the patch. I was finally able to test it and it fixes my problem. I have been able to successfully compile and install Ocaml 3.08.2...
Hi, I've been using Ocaml for some time now, but have not tried profiling before (iirc). When I run my program after compiling with "ocamlopt -p" I get a...

I've just started working with ocaml, trying out various functions. The following code let data = [1,2,3,4,5,6];; let s = (List.fold_left (+) data) in...
In fact let data = [1,2,3,4,5,6];; defines a list containing only one element: the 6-tuple (1,2,3,4,5,6). I think you mean let data = [1;2;3;4;5;6];; -- ...
... A list constant is delimited with ';'. What you have there is a list with one element which is six-tuple. What you want is: let data = [1;2;3;4;5;6];; ......

Hi, let data=[1;2;3;4;5;6] !!!!! "," is for nuple (1,2,3,4,5) is a 5-uple of type int * int * int * int * int [1;2;3;4;5] is a list of type int list Cheers ...
