Today I found some time to install Tcl/Tk for Aqua, which is the native user
interface for Macintosh OS X and configured ocaml-3.06 so that its labltk
links with the Tcl/Tk for Aqua.

labltk, ocamlbrowser, and accompanying examples (hello, eyes, tetris, ...)
under otherlibs/labltk/examples_labltk compiles with little problem.

With a small effort you could make a clickable native application for Mac OS
X.

Though behavior of some applications is weird (some, for instance
ocamlbrowser, are very weird) but I can tolerate.

The following is an outline of installation steps (Mac OS 10.2.2 and higher
is expected):

0. Visit "www.tcl.tk" and get TclTkAqua_8.4.1-Jaguar.dmg, and install it.

After installation make four symbolic links as show followingly (you need to
be a super user):

/Library/Frameworks/Tcl.framework:

lr-xr-xr-x  1 root  staff   11 Jan  7 18:58 libtcl -> libtcl8.4.a
lr-xr-xr-x  1 root  staff   16 Jan  7 18:58 libtcl8.4.a -> Versions/8.4/Tcl

/Library/Frameworks/Tk.framework:

lr-xr-xr-x  1 root  staff   10 Jan  7 18:58 libTk -> libTk8.4.a
lr-xr-xr-x  1 root  staff   15 Jan  7 18:58 libTk8.4.a -> Versions/8.4/Tk

1. Extract ocaml-3.06.tgz and apply the attached patch (tcltk4aqua.patch)

cd ocaml-3.06; patch -p1 tcltk4aqua.patch

2. Execute the configuration script

sh ocaml4darwin.conf

This script configures ocaml-3.06 for Mac OS X and for the Tcl/Tk just
installed.  It also builds "world, opt, and opt.opt".

 You might want to save the existing ocaml-3.06 installation.  In that case,
modify the script appropriately.

3. Install the ocaml-3.06 system

make install

4. Store makeapp.sh and Info.plist at the labltk's examples directory and
build clickable applications.

4.1 store makeapp.sh and Info.plist in "otherlibs/labltk/examples_labltk"
directory.

4.2 build examples

cd otherlibs/labltk/examples_labltk
make

4.3 build clickable applications

./makeapp hello
./makeapp tetris
...

4.4 locate the Finder application to the examples_labltk directory and start
the clickable applications.

Good luck
