The README from the tarball is also attached below.

----------------------------------------------------------------------
This tarball / directory contains an example of cross-compiling OCaml
LablGtk programs for Windows, which I originally demonstrated at the
OCaml Users Conference meeting Feb 2009.
You will need to start here:
http://www.fedoraproject.org/wiki/MinGW
It's a good idea to join the Fedora MinGW mailing list (mentioned on
the above page), and if you have any problems post them on the mailing
list.

You must install Fedora 10 which you will need to upgrade to Fedora
Rawhide (the development version):
https://fedoraproject.org/wiki/Releases/Rawhide
If you don't have Fedora Rawhide already, try installing it in a
virtual machine.
OCaml cross-compilation is _not_ supported on RHEL, EPEL, CentOS,
Fedora <= 10, etc at this time, although we may add these
distributions in future.
The software required is partially in Rawhide and partially in a
separate repository. Create and edit a file /etc/yum.repos.d/mingw.repo
containing:
[mingw]
name=MinGW
baseurl=http://www.annexia.org/tmp/mingw/fedora-rawhide/x86_64
enabled=1
gpgcheck=0
Replace "x86_64" with "i386" if you have a 32 bit machine. We do not
compile the temporary repository for non-x86 architectures at this
time.
Now install the packages and their deps by typing this command (as
root):
yum install \
ocaml ocaml-x11 ocaml-findlib-devel \
mingw32-gcc \
mingw32-ocaml mingw32-ocaml-findlib mingw32-ocaml-lablgtk2 \
mingw32-nsis mingw32-nsiswrapper \
wine autoconf automake
You should now be able to compile the Windows demo by doing:
mingw32-configure
make
and then run/test it in Wine by doing:
wine gtk_test.exe
To compile the Windows installer you will first need to install the
program (this is an arcane requirement which will be fixed in future).
As root do:
make install
Then as a normal user do:
make installer.exe
Copy installer.exe to a Windows machine to try it.

Developers: The only files you need to copy in order to create an
autotools package are 'configure.ac' and 'Makefile.am'. After copying
these to a new directory, run:
autoreconf -i
(You may need to create empty files 'README', 'NEWS' etc. as
instructed).

For questions/problems please join the Fedora MinGW mailing list.
