= Building Cocotron for use with CCL =

First, install Xcode on a Macintosh.

Next, install the Cocotron tools.  Follow the directions found at
http://www.cocotron.org/Tools/InstallCDT.

With the tools installed, you are ready to build the Cocotron
sources.  You will need to install Mercurial.  Check out the source code with
{{{
hg clone http://cocotron.googlecode.com/hg/ cocotron
}}}

Next, apply the patch from $REPO/trunk/aux/cocotron/win32/cocotron/cocotron-r59942ee67d15.patch
(This patch contains some changes to NSDocument.m and NSApplication.m.)
Something like this will probably work:
{{{
$ cd cocotron/AppKit
$ patch -p2 </path/to/patch
}}}

Open cocotron/Cocoa/Cocoa.xcodeproj, and build it.

Now, do the following:
{{{
$ mkdir /tmp/cocotron
$ cd /Developer/Cocotron/1.0/Windows/i386/Frameworks
$ /Developer/Cocotron/1.0/bin/retargetBundle -F . -framework Foundation -framework AppKit  -destination /tmp/cocotron
}}}

To build interfaces, you need an interface translator.  The process is similar to that outlines in BuildFFIGEN, but you use the patches
in http://svn.clozure.com/publicsvn/ffigen4/branches/ffigen-x-cocotron, and the gcc sources from the Cocotron tools.

Now, assuming that on your Windows system you have a ccl:cocotron; directory, do the following steps:
  * tar up /tmp/cocotron and untar it into ccl:cocotron; on the Windows system
  * get the win32-headers directory from svn onto your Macintosh system, go into win32-headers/cocoa/C/ and run populate.sh.
  * tar up win32-headers/cocoa/C and move it over to the Windows system
  * on the Windows system, parse the ffi files in the usual way, i.e., (require 'parse-ffi) (dotimes (i 2) (parse-standard-ffi-files :cocoa))

If you're lucky, it might work.
