Can't Build oclpb on Win 7 64 bit

[george-azzari]

Hi there,

I am trying to play with CLyther, but I encountered some problems in building oclpb on my Windows 7 (64 bit) machine. I am currently using the Enthought Python Distribution. The easy_install way doesn't work, and I get this message:

Searching for oclpb
Reading http://pypi.python.org/simple/oclpb/
Couldn't find index page for 'oclpb' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading http://pypi.python.org/simple/
No local packages or download links found for oclpb
error: Could not find suitable distribution for Requirement.parse('oclpb')

If I try to download the source manually and build, I get instead this error:

running build
running build_py
running build_ext
skipping 'opencl\clgl.c' Cython extension (up-to-date)

In file included from opencl\clgl.c:235:0:
opencl/cl_header.h:4:23: fatal error: CL/opencl.h: No such file or directory
compilation terminated.

I have opencl.h located in C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\include\CL, but the compiler is not finding it. I tried to play with the environment variables, but with no success. Can anyone give me a little help?

Thank you,
George
