Dear developers,
I managed to compile PyOpenCL on my system (Windows 7 64bit, Python 2.6
64bit, AMD Radeon 5870, Visual Studio 2008 Prof., boost 1.43). Here I
want to share the procedure:
1) Compile boost libraries
took source distribution of boost 1.43; created bjam; created directory
'x64' in boost directory
bjam --toolset=msvc-9.0 address-model=64 --build-type=complete
--stagedir=x64
added x64 subdirectory to search path
2) Compile PyOpenCL. Took it from git trunk (0.92beta). Edited my
siteconf.py:
---------------
BOOST_LIB_DIR = [r'c:\users\i-med-thalhammer\boost\boost_1_43_0\x64\lib']
BOOST_INC_DIR = [r'c:\users\i-med-thalhammer\boost\boost_1_43_0']
BOOST_COMPILER = 'msvc'
BOOST_PYTHON_LIBNAME = ['boost_python-vc90-mt-1_43']
USE_SHIPPED_BOOST = False
CL_TRACE = False
CL_ENABLE_GL = True
CL_INC_DIR = [r'c:\Program Files (x86)\ATI Stream\include']
CL_LIB_DIR = [r'c:\Program Files (x86)\ATI Stream\lib\x86_64']
CL_LIBNAME = ['OpenCL']
CXXFLAGS = ['/EHsc', '/DBOOST_PYTHON_NO_PY_SIGNATURES']
LDFLAGS = ['/FORCE']
---------------
python setup.py install
To enable OpenGL interoperability I had to change wrap_cl.hpp:
---------------------------
diff --git a/src/wrapper/wrap_cl.hpp b/src/wrapper/wrap_cl.hpp
index b12286c..d9c46ff 100644

Compiling gave a couple of warnings since size_t and int or cl_uint are
different.
3) To test OpenGL interoperability I changed examples/gl_interop_demo.py:

--------------------------
I didn't know how to make these changes platform independent.
In a similar manner, I managed to compile PyOpenCL for 32bit Python,
using precompiled 32bit libraries for boost 1.42.
Thanks for providing PyOpenCL, it is a great package.
