We dont yet have a how to on the windows build process, though we
certainly would like to get one going!

(Are there any volunteers on the list to assist with this?) In the
long term, I think it would be preferable to include a windows
installer so that users dont have to build OCIO at all!

You should also know that Nuke 6.3v7 and above ship with OCIO (on all
platforms), so if you're only looking to experiment with OCIO, as a
Nuke user, you can just experiment with later versions.

It may occur silly to ask. do you have startup on how to build ocio for
windows. Does not matter if it gives a problem later...but a "how to start"
will greatly help,

what version of msvc should I go for. I want to first try for nuke 6.3v1.

After much struggle, I finally managed to get OCIO built on Windows, but
there are several apparent bugs in the build process that require manual
intervetion to work around.

I ran CMake from the Visual Studio 2008 command prompt (32-bit), with the
following command line:
cmake -D CMAKE_INSTALL_PREFIX=c:\ocio-em64t -D CMAKE_BUILD_TYPE=Release
^
-D OCIO_BUILD_STATIC=OFF -D BOOST_ROOT=c:\boost_1_49_0 ^
-D OCIO_BUILD_APPS=OFF -D OCIO_USE_BOOST_PTR=ON ^
-D PYTHON_VERSION="2.6.5" -D PYTHON_LIB=C:/Python26/libs ^
-D PYTHON_INCLUDE=C:/Python26/include ^
-D OCIO_LINK_PYGLUE=ON ^
-G "NMake Makefiles" ..\

Bug #1: I have to specifiy OCIO_BUILD_STATIC here, otherwise it will build
the static lib and the import lib at the same location -- the former
overwrites the latter, which prevents me from linking with the DLL.

Bug #2: The build fails with "NMAKE : fatal error U1073: don't know how to
make 'ext\dist\lib\libyaml-cppmd.lib'"

It turns out that yaml-cpp is built in debug mode, even though this is a
release build. So libyaml-cppmdd.lib (note the extra 'd') exists, but the
release version of the library (upon which OpenColorIO.dll depends) does
not. I worked around this by building yaml-cpp separately and copying the
correct lib into the build directory.

Bug #3: building the python bindings fails because PyDoc.h doesn't exist.
I worked around this by running createPyDocH.py manually.

I'm afraid CMake is something of a mystery to me so I can't offer much
help in the way of fixing these bugs. But if anyone has suggestions or
proposed fixes, I'm happy to try them out.
