changes after n-g-d 194.36.31-4

[Tomasz Rybak]

I have checked with 256.53-1. I could check with 195.x, but
would like to avoid messing with drivers to much if it is not
necessary.

OK, already made changes in SVN, will wait with building till
new version.

np. That's why I subscribe to NVIDIA packaging list - I trace changes
in drivers/libraries so I know whether they touch my packages.

Yes, I had to symlink, and later ldconfig to compile
(forgot that dpkg -P lib* rebuilds library cache).

Upstream made sure that PyOpenCL works with 1.1.
OTOH NVIDIA drivers support OpenCL 1.1 from 258.x so.
Bindings compile but when trying to use I got:
Traceback (most recent call last):
  File "make_constants.py", line 1, in <module>
    import pyopencl as cl
  File
"/usr/src/cuda/pyopencl-0.92/build/lib.linux-x86_64-2.6/pyopencl/__init__.py", line 3, in <module>
    import pyopencl._cl as _cl
ImportError: /usr/src/cuda/pyopencl-0.92/build/lib.linux-x86_64-2.6/pyopencl/_cl.so: undefined symbol: clEnqueueReadBufferRect

clEnqueueReadBufferRect is new function from OpenCL 1.1.

oclDeviceQuery from CUDA toolkit 3.1 prints:
oclDeviceQuery, Platform Name = NVIDIA CUDA, Platform Version = OpenCL
1.0 CUDA 3.1.1, SDK Revision = 6161726, NumDevs = 1

So I am afraid that we need to stick with 1.0 headers
until you package 260.x ;-)

PyCUDA dynamically compiles CUDA kernels, so it needs nvcc installed.
That's why python-pycuda both Depends and Build-Depends on
nvidia-cuda-toolkit.

In summary - change (with 1.0 headers) should be OK, but
send me the new package for testing.
