Hi Andreas,
yes CL/cl.h exists.
I were able to get a few steps further and successfully compile it with pip by
setting the
C++ library path (LIBRARY_PATH) and and the C++ include path
(CPLUS_INCLUDE_PATH).
Unfortunately i get an error now when importing pyopencl in python.
>>> import pyopencl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "~/gpupy/local/lib/python2.7/site-packages/pyopencl/__init__.py", line
28, in
<module>
import pyopencl._cl as _cl
ImportError: libOpenCL.so.1: cannot open shared object file: No such file or
directory
Even though I am able to run
gcc test.cpp -lOpenCL -o test
without any problem.
I don't understand though how the linking of those extensions actually work. In
the library
path I don't have libOpenCL.so.1 but I have libnvidia-opencl.so.1 .
I guess this libnvidia-opencl.so.1 is responsible for -lOpenCL to work but
_cl.so tries to
find libOpenCL.so.1 based on the library name.
I don't know if I am on the right track. I guess I have to investigate the
pyopencl source
files to understand how it compiles. Or do you have an idea?
Best Regards
Jesse
