ImportError when following contributing instructions

[TomNicholas]

Following these instructions https://numcodecs.readthedocs.io/en/stable/contributing.html#creating-a-development-environment

I get this error whenever I try to import anything from numcodecs

from numcodecs import blosc

E   ImportError: dlopen(/Users/tom/Documents/Work/Code/numcodecs/numcodecs/blosc.cpython-312-darwin.so, 0x0002): symbol not found in flat namespace '_blosc_cbuffer_complib'

Oh I didn't read the instructions properly - I had not used --recursive when git cloning.

Yeah this can be confusing if one doesn't know this has (or hasn't used) git submodules before

If there are tweaks that would make this clearer, please feel free to send a PR

IMO the best thing here would be to not use submodules for blosc, e.g. by using the version of blosc on pypi. I think @dstansby is working on this in #571

[jakirkham]

That is a different conversation altogether best served by a dedicated issue

For example:

• Use blosc wheels #262

I agree that it's best served by a dedicated issue, such as the one I linked :)
