       Release notes on the MS Windows ports of Objective Caml
       -------------------------------------------------------

There are no less than four ports of Objective Caml for MS Windows available:
  - a native Win32 port, built with the Microsoft development tools;
  - a native Win32 port, built with the Cygwin/MinGW development tools;
  - a port consisting of the Unix sources compiled under the Cygwin
    Unix-like environment for Windows;
  - a native Win64 port (64-bit Windows), built with the Microsoft
    development tools.

Here is a summary of the main differences between these ports:

                                      Native MS     Native MinGW        Cygwin

Restrictions on generated executables?  none            none            yes (*)

(*) Cygwin-generated .exe files refer to a DLL that is distributed under
the GPL.  Thus, these .exe files can only be distributed under a license
that is compatible with the GPL.  Executables generated by MSVC or by
MinGW have no such restrictions.

(**) The debugger is supported but the "replay" function of it are not enabled.
Other functions are available (step, goto, run...).

The remainder of this document gives more information on each port.

------------------------------------------------------------------------------

           The native Win32 port built with Microsoft Windows SDK
           ------------------------------------------------------

REQUIREMENTS:

This port runs under MS Windows 7 (32 and 64 bits), Vista, XP, and 2000.

The base bytecode system (ocamlc, ocaml, ocamllex, ocamlyacc, ...)
runs without any additional tools.

The native-code compiler (ocamlopt) requires the Microsoft Windows SDK
(item [1]) and the flexdll tool (item [2]).

Statically linking Caml bytecode with C code (ocamlc -custom) also requires
items [1] and [2].

The LablTk GUI requires Tcl/Tk 8.5 (item [3]).


INSTALLATION:

The binary distribution is a self-installing executable archive.
Just run it and it should install OCaml automatically.

To run programs that use the LablTK GUI, the directory where the
DLLs tk85.dll and tcl85.dll were installed (by the Tcl/Tk
installer) must be added to the PATH environment variable.

To compile programs that use the LablTK GUI, the directory where the
libraries tk85.lib and tcl85.lib were installed (by the Tcl/Tk
installer) must be added to the library search path in the LIB
environment variable.  E.g. if Tcl/Tk was installed in C:\Tcl, add
"C:\Tcl\lib" to the LIB environment variable.

THIRD-PARTY SOFTWARE:

[1] Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 Service Pack 1.
    Can be downloaded for free from
    http://www.microsoft.com/downloads/en/default.aspx
    under the name "Microsoft Windows 7 SDK".

[2] flexdll version 0.23 or later.
    Can be downloaded from http://alain.frisch.fr/flexdll.html

[3] TCL/TK version 8.5.  Windows binaries are available as part of the
    ActiveTCL distribution at http://www.activestate.com/products/ActiveTcl/


RECOMPILATION FROM THE SOURCES:

The command-line tools can be recompiled from the Unix source
distribution (ocaml-X.YY.Z.tar.gz), which also contains the files modified
for Windows.

You will need the following software components to perform the recompilation:
- Windows NT, 2000, XP, Vista, or 7 (32 or 64 bits).
- Items [1], [2] and [3] from the list of recommended software above.
  Make sure to install the 32-bit version of TCL/TK, even if you are
  compiling on a 64-bit Windows.
- The Cygwin port of GNU tools, available from http://www.cygwin.com/
  Install at least the following packages: diffutils, make, ncurses.

First, you need to set up your cygwin environment for using the MS
tools.  The following assumes that you have installed [1], [2], and [3]
in their default directories.  If this is not the case, you will need
to adjust the paths accordingly.

  Open a Windows Command Prompt and enter the following command:
    set PFPATH=C:\Program Files
  If you are compiling on the 64-bit version of Windows 7, enter the
  following instead:
    set PFPATH=C:\Program Files (x86)

  Then enter the following commands:
    cd "%PFPATH%\Microsoft Visual Studio 9.0\VC\bin"
    vcvars32
    echo VCPATH="`cygpath -p '%Path%'`" >C:\cygwin\tmp\msenv
    echo LIB="%LIB%;C:\Tcl\lib" >>C:\cygwin\tmp\msenv
    echo LIBPATH="%LIBPATH%" >>C:\cygwin\tmp\msenv
    echo INCLUDE="%INCLUDE%;C:\Tcl\include" >>C:\cygwin\tmp\msenv
    echo FLPATH="`cygpath '%PFPATH%\flexdll'`" >>C:\cygwin\tmp\msenv
    echo PATH="${VCPATH}:$PATH:${FLPATH}" >>C:\cygwin\tmp\msenv
    echo export PATH LIB LIBPATH INCLUDE >>C:\cygwin\tmp\msenv
    echo export OCAMLBUILD_FIND=/usr/bin/find >>C:\cygwin\tmp\msenv

  Open a Cygwin shell and enter the following commands:
    tr -d '\r' </tmp/msenv >.msenv32
    echo '. $HOME/.msenv32' >>.bashrc

Now, close the Command Prompt and the shell and you're set up for
using the MS tools under Cygwin.


To recompile OCaml, start a new Cygwin shell and change to the top-level
directory of the OCaml distribution.  Then, do

        cp config/m-nt.h config/m.h
        cp config/s-nt.h config/s.h
        cp config/Makefile.msvc config/Makefile

Then, edit config/Makefile as needed, following the comments in this file.
Normally, the only variables that need to be changed are
        PREFIX      where to install everything
        TK_ROOT     where TCL/TK was installed

Finally, use "make -f Makefile.nt" to build the system, e.g.

        make -f Makefile.nt world
        make -f Makefile.nt bootstrap
        make -f Makefile.nt opt
        make -f Makefile.nt opt.opt
        make -f Makefile.nt install

NOTES:

* The VC++ compiler does not implement "computed gotos", and therefore
generates inefficient code for byterun/interp.c. Consequently, the
performance of bytecode programs is about 2/3 of that obtained under
Unix/GCC or Cygwin or Mingw on similar hardware.

* Libraries available in this port: "num", "str", "threads", "graphics",
"labltk", and large parts of "unix".

* The replay debugger is partially supported (no reverse execution).

CREDITS:

The initial port of Caml Special Light (the ancestor of Objective Caml)
to Windows NT was done by Kevin Gallo at Microsoft Research, who
kindly contributed his changes to the Caml project.

The graphical user interface for the toplevel was initially developed
by Jacob Navia, then significantly improved by Christopher A. Watford.

------------------------------------------------------------------------------

           The native Win32 port built with Mingw
           --------------------------------------

REQUIREMENTS:

This port runs under MS Windows Vista, XP, and 2000.

The base bytecode system (ocamlc, ocaml, ocamllex, ocamlyacc, ...)
runs without any additional tools.

The native-code compiler (ocamlopt), as well as static linking of
Caml bytecode with C code (ocamlc -custom), require
the Cygwin development tools, available at
        http://www.cygwin.com/
and the flexdll tool, available at
        http://alain.frisch.fr/flexdll.html
You will need to install at least the following Cygwin packages (use
the Setup tool from Cygwin):
binutils, gcc-core, gcc-mingw-core, mingw-runtime, w32api.

Do *not* install the Mingw/MSYS development tools from www.mingw.org:
these are not compatible with this Caml port (@responsefile not
recognized on the command line).

The LablTk GUI requires Tcl/Tk 8.5.  Windows binaries are available
as part of the ActiveTCL distribution at
http://www.activestate.com/products/ActiveTcl/
Note that you will need to install the 32-bit version of ActiveTCL,
even if you are on a 64-bit version of Windows.

INSTALLATION:

The binary distribution is a self-installing executable archive.
Just run it and it should install OCaml automatically.

To run programs that use the LablTK GUI, the directory where the
DLLs tk85.dll and tcl85.dll were installed (by the Tcl/Tk
installer) must be added to the PATH environment variable.

To compile programs that use the LablTK GUI, the directory where the
libraries tk85.lib and tcl85.lib were installed (by the Tcl/Tk
installer) must be added to the library search path in the LIB
environment variable.  E.g. if Tcl/Tk was installed in C:\tcl, add
"C:\tcl\lib" to the LIB environment variable.


RECOMPILATION FROM THE SOURCES:

You will need the following software components to perform the recompilation:
- Windows NT, 2000, XP, or Vista.
- Cygwin: http://sourceware.cygnus.com/cygwin/
  Install at least the following packages: binutils, diffutils,
    gcc-core, gcc-mingw-core, make, mingw-runtime, ncurses, w32-api.
- TCL/TK version 8.5 (see above).
- The flexdll tool (see above).

Do *not* install the standalone distribution of MinGW, nor the
companion MSYS tools: these have problems with long command lines.
Instead, use the version of MinGW provided by Cygwin.

Start a Cygwin shell and unpack the source distribution
(ocaml-X.YY.Z.tar.gz) with "tar xzf".  Change to the top-level
directory of the OCaml distribution.  Then, do

        cp config/m-nt.h config/m.h
        cp config/s-nt.h config/s.h
        cp config/Makefile.mingw config/Makefile

Then, edit config/Makefile as needed, following the comments in this file.
Normally, the only variables that need to be changed are
        PREFIX      where to install everything
        TK_ROOT     where TCL/TK was installed

Finally, use "make -f Makefile.nt" to build the system, e.g.

        make -f Makefile.nt world
        make -f Makefile.nt bootstrap
        make -f Makefile.nt opt
        make -f Makefile.nt opt.opt
        make -f Makefile.nt install


NOTES:

* Libraries available in this port: "num", "str", "threads", "graphics",
  "labltk", and large parts of "unix".

* The replay debugger is partially supported (no reverse execution).

------------------------------------------------------------------------------

                  The Cygwin port of Objective Caml
                  ---------------------------------

REQUIREMENTS:

This port requires the Cygwin environment from Cygnus/RedHat, which
is freely available at:
          http://www.cygwin.com/

It also requires the flexdll tool, available at:
          http://alain.frisch.fr/flexdll.html

This port runs under all versions of MS Windows supported by Cygwin.


INSTALLATION:

We do not distribute binaries for this port, but they can be found
in the Cygwin distribution (use the Setup tool from Cygwin and select
the OCaml packages).  Alternatively, recompile from the source distribution.


RECOMPILATION FROM THE SOURCES:

Just follow the instructions for Unix machines given in the file INSTALL.


NOTES:

The libraries available in this port are "num", "str", "threads",
"unix" and "labltk".  "graph" is not available.
The replay debugger is supported.

------------------------------------------------------------------------------

       The native Win64 port built with Microsoft Windows SDK
       ------------------------------------------------------

REQUIREMENTS:

This port runs under MS Windows XP 64, Windows Server 64, and
Windows 7 64 on Intel64/AMD64 machines.

The base bytecode system (ocamlc, ocaml, ocamllex, ocamlyacc, ...)
runs without any additional tools.

Statically linking Caml bytecode with C code (ocamlc -custom) requires the
Microsoft Platform SDK compiler (item [1] in the section
"third-party software" below) and the flexdll tool (item [2]).

The native-code compiler (ocamlopt) requires the Microsoft compiler
and the Microsoft assembler MASM64 (item [1]) and the flexdll tool (item [2]).

The LablTk GUI is not available in this version.

INSTALLATION:

There is no binary distribution yet.  Please compile from sources as
described below.


THIRD-PARTY SOFTWARE:

[1] Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 Service Pack 1.
    Can be downloaded for free from
    http://www.microsoft.com/downloads/en/default.aspx

        cp config/m-nt.h config/m.h
        cp config/s-nt.h config/s.h
        cp config/Makefile.msvc64 config/Makefile

Then, edit config/Makefile as needed, following the comments in this file.
Normally, the only variable that need to be changed is
        PREFIX      where to install everything

Finally, use "make -f Makefile.nt" to build the system, e.g.

        make -f Makefile.nt world
        make -f Makefile.nt bootstrap
        make -f Makefile.nt opt
        make -f Makefile.nt opt.opt
        make -f Makefile.nt install


NOTES:

* Libraries available in this port: "num", "str", "threads", "graphics",
  and large parts of "unix".

* The replay debugger is partially supported (no reverse execution).

* The graphical browser ocamlbrowser is not supported.
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
