Release notes on the MS Windows ports of Objective Caml
|
||||
-------------------------------------------------------
|
||||
|
||||
Starting with OCaml 3.01, there are now two ports of Objective Caml
|
||||
for MS Windows available:
|
||||
- a native Win32 port, built with the Microsoft development tools;
|
||||
Starting with OCaml 3.05, there are now no less than three ports of
|
||||
Objective Caml for MS Windows available:
|
||||
- a native Win32 port, built with the Microsoft development tools (non-free);
|
||||
- a native Win32 port, built with the MinGW development tools (free);
|
||||
- a port consisting of the Unix sources compiled under the Cygwin
|
||||
Unix-like environment for Windows.
|
||||
Unix-like environment for Windows (free).
|
||||
|
||||
The Cygwin port requires only free software, runs faster in bytecode
|
||||
mode, and provides a more thorough emulation of the Unix library.
|
||||
It currently lacks the threads library and the ability to interface
|
||||
with COM components via CamlIDL. No graphical user interface to the
|
||||
OCaml toplevel is provided.
|
||||
Here is a summary of the main differences between these ports:
|
||||
|
||||
The native Win32 port has threads and COM support, but is slower in
|
||||
bytecode, does not implement some of the functionality of the Unix library,
|
||||
and requires MS Visual C++ version 6 for compilation in -custom mode
|
||||
and in native-code mode. A simple graphical user interface to the
|
||||
OCaml toplevel is provided.

INSTALLATION:
|

|
||||
The binary distribution is a .tar.gz archive that unpacks in
|
||||
usr/local/bin and usr/local/lib/ocaml/. To install, just open
|
||||
a "bash" windows and type:
|
||||
cd /
|
||||
tar xvzf /full/path/to/ocaml-X.XX-cygwin.tar.gz
|
||||
|
||||
Make sure that /usr/local/bin is in the PATH environment variable.
|
||||
For various reasons, no binary distribution of this port is available.
|
||||
You need to recompile from the source distribution.

REQUIREMENTS:
|

|

This port runs under MS Windows 95, 98, ME, NT and 2000 on Intel IA32
|
||||
machines.
|

|
||||
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 MinGW
|
||||
development tools, which is free software available at
|

The LablTk GUI requires Tcl/Tk 8.0 for MinGW, available from

|

You will need the following software components to perform the recompilation:

- Windows NT, 2000, or XP (we advise against compiling under Windows 95/98/ME)
|
||||
- MinGW: http://www.mingw.org/
|

- Cygwin: http://sourceware.cygnus.com/cygwin/
|
||||
- Make sure that MinGW binaries occur before Cygwin binaries in the PATH
|
||||
(e.g. PATH=/mingw/bin:/usr/bin/:...)
|
||||
- TCL/TK version 8.0 for MinGW (see above).
|
||||
|
||||
Start a Cygwin shell and unpack the source distribution
|
||||
(ocaml-X.YZ.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
