Everything now works. Details...
First of all I've failed to get Boost 1.41.0 to compile correctly with
Python support on Windows XP (which relates to the earlier messages in this
thread). Each time the compilation would succeed but
boost_python-vc90-mt-1_41.dll would reference PYTHON25.DLL rather than
PYTHON26.DLL.
DependencyWalker helped me locate this problem (cheers Andreas!) but I
couldn't force it to build a Python2.6 version. To be clear - Python 2.5
was uninstalled weeks back, there are no traces that I can see (no PATH, no
directories etc) and using --debug-configuration with bjam shows that
Python2.6 is found and built against...but still PYTHON25.DLL is referenced
in the DLL. I tried configuring project-config.jam and forcing "python=2.6"
with bjam too. 4 days were spent banging my head against this problem, I
hope this warning saves someone else the trouble.
Switching to Boost 1.39.0 solved everything - it built from source first
time (using "bjam --build-type=complete stage") and delivered dlls that
DependencyWalker reported depending on PYTHON26.DLL.
After this pyCUDA would build and install but I couldn't run any demos
because nvcc failed. I checked that cl.exe existed but it wasn't in the
PATH. For reference this is the sort of error I saw:
---
C:\Documents and Settings\parc\My
Documents\Downloads\pycuda_git\pycuda\examples>python demo.py
nvcc fatal : Cannot find compiler 'cl.exe' in PATH
Traceback (most recent call last):

pycuda.driver.CompileError: nvcc compilation of

The solution was to add cl.exe and a required dll directory for Visual
Studio 2008 (VS9) to the PATH, these were the relevant directories on my
machine:
C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\;C:\Program
Files\Microsoft Visual Studio 9.0\Common7\IDE
After this the demos work - many thanks Andreas for providing the package!
Ian.
