Hi, Following Damien's announcement, the installer for windows has been updated, and is now available at . This installer will: * install OCaml, findlib and flexdll * (optional) install Emacs with the caml-mode set up and the right file associations in the Windows explorer, * (optional) install ActiveTCL so that OCamlBrowser and labltk can work properly * (optional, required for native compilation) launch the cygwin setup with the right packages pre-configured so that you have a working OCaml development environment, where you can run find, make, as, ocamlbuild, and the like. This installer does not feature any package management system. However, it should work with odb . Odb successfully installed lwt on my test machine, as well as easy-format, and a few other libraries from Jane Street. The installer is generated using NSIS, and the NSIS script file may contains bugs. If you find any, please submit a patch using the GitHub interface! Cheers, jonathan
