______________________________Hello,I've change the toplevel of Ocaml to replace the standard input and output by named pipes on Windows.To achieve this, I've change the toploop.ml (https://github.com/ocaml/ocaml/blob/trunk/toplevel/ ) to include the named pipestoploop.ml of Ocamlnet (http://projects.camlcity.org/projects/dl/ocamlnet-4.1.2/ ).doc/html-main/Netsys_win32. html#1_Supportfornamedpipes After that, I tried to understand how I could compile this custom toplevel.I want to compile the toplevel to have a .exe, so I could avoid using Cygwin to launch the application.I've run the makefile of the git repository of Ocaml and tried to follow the sequence of compilation for the toplevel.I use ocamlopt to have a native aplication and ocamlfind to link toploop.ml with the library ocamlnet(via the package netsys where the win32 named pipe are defined) and unix for catching exceptions.I use Opam : 1.3.0~dev, Ocaml : 4.03.0 and Cygwin on Windows 7.So I write a Makefile (see the attachement) and when I launch it, I get this :____________________________________________________________ __________ ocamlopt -g -I +compiler-libs ocamlcommon.cmxa ocamlbytecomp.cmxa ocamlcommon.a ocamlbytecomp.a -c genprintval.mli

** Cannot resolve symbols for tmp_ocamltoplevel.a(topdirs.o):
caml_get_current_environment
File "caml_startup", line 1:
Error: Error during linking______________________________ __________ But I don't know how to resolve this error.I find that "caml_get_current_environment" is defined in meta.c (and used in topdirs.ml)But I think that meta.c is in the ocamlbytecomp.cmxa library, so I don't know why the linker don't find the symbols.Someone know how to resolve this problem ?Thank you in advance !
