I don't know what got done, but I did a git pull:
C:\Users\Keith\Desktop\pyopencl\pyopencl>git pull
c91a092..cffa356 master -> origin/master
Updating c91a092..cffa356
Fast-forward
pyopencl/__init__.py | 14 +++++++++++++-
1 files changed, 13 insertions(+), 1 deletions(-)
and rebuilt my pyopencl on my ATI HD5870 computer, and it works now!
If it really isn't a pyopencl thing, is it possible that I installed some
windows update that I don't know about that somehow magically helped me?

I also finally got the gl interop demo and Enjalot's "part2" demo working on
my
CPU context-only machine. I used the newest code in the repo, but I don't know
if that matters. I ended up having to change the context acquisition code from
this:
else:
ctx = cl.Context(properties=[
(cl.context_properties.PLATFORM, plats[0])]
+ get_gl_sharing_context_properties())
to this:
else:
ctx = cl.Context(properties=[
(cl.context_properties.PLATFORM, plats[0])]
+ get_gl_sharing_context_properties(), devices =
[plats[0].get_devices()[0]])
Now it works.
Any idea why that matters for me?

Hey Keith,
I'm not sure exactly why it matters on Windows, but by specifying the device
you are using clCreateContext rather than clCreateContextFromType when
creating the context. When using a CPU that can share with GL it probably
matters, you can see some C API examples here:

Can you send a patch so that the resulting example should work
everywhere?
Thanks!

Is something this simple ok? It works on my mac and my CPU only Windows machine.
I can't test it on my HD5870 Windows machine for awhile.

line 28:
if sys.platform == "darwin":
ctx = cl.Context(properties=get_gl_sharing_context_properties(),

Sure. I've committed something like this. We'll see if we get
complaints.
Thanks!
