First base of 'CUkernelNodeAttrValue_v1' is not an extension type

[bertmaher]

I'm trying to compile cuda-python in a fairly minimal conda environment (nothing installed but the requirements), with cuda-11.6 installed, and seeing several instances of the following sort of error:

      Error compiling Cython file:
      ------------------------------------------------------------
      ...
              Get memory address of class instance

          """
          pass

      cdef class CUkernelNodeAttrValue_v1(CUlaunchAttributeValue_union):
                                         ^
      ------------------------------------------------------------

      cuda/cuda.pxd:2637:36: First base of 'CUkernelNodeAttrValue_v1' is not an extension type

I do have other cuda versions installed alongside 11.6 but judging from the output of Parsing headers in "/usr/local/cuda-11.6/include" it seems like it's probably finding the right version? Any advice on how to get past this, or debug it? Thanks!

https://nvidia.github.io/cuda-python/release/11.8.0-notes.html#source-builds
and
Issue #22

In 11.7.1, a new requirement to source builds was added where the latest CTK must be used. The above links talk about it in further detail.
I see that only the release notes mention this (but neither README.md nor install page) since that release, I'll keep this issue open until they're both updated.

Release v11.8.1 updates both README.md and install page.

Closing.
