Sorry, I'm genuinely confused :)
What does the cuda.h correspond to that is packaged with cudatoolkit
(since cudatoolkit does not contain a libcuda.so)?
The nvidia driver (and also the linux kernel for that matter) all seem
to provide a cuda.h. Is the cudatoolkit cuda.h the incorrect one to
use for pycuda?
What is the conceptual difference between libcuda.so and libcudart.so?
Using libcuda.so of the nvidia driver I get the above error (undefined
symbol: cuTexRefSetAddress2D_v3).
_driver.so is linked against the following:
