@MarsSeed: You said “pls remove the nonexistent optdepends”
But why?

It’s defined here: https://github.com/zarr-developers/numcodecs/blob/955019b55a31b4a03c76f62edfde5df2301282c4/numcodecs/blosc.pyx#L21
I guess that cython syntax means it needs /usr/include/blosc.h (in the
blosc
package) at build time. I should add that to build deps.tujir commented on 2022-12-19 14:39 (UTC)
Do we need python-blosc as dependency?
ImportError: cannot import name 'Blosc' from 'numcodecs' (/usr/lib/python3.10/site-packages/numcodecs/init.py)

Hi, I have the following message error

Hi, can you add python-wheel and python-setuptools-scm to make dependencies? The package fails to build without them in a clean environment

good idea, done!

I tried compiling this on a relatively old computer (Nehalem) and got an illegal (hardware) instruction as reported here: https://github.com/zarr-developers/numcodecs/issues/252
The reason is apparently that the cpu doesn't support avx2 instructions.
I recommend to change in the PKGBUILD export CFLAGS="$CFLAGS -msse2 -mavx2" to export CFLAGS="$CFLAGS -march=native"
so only the available instructions will be build (both sse2 and avx2 when available), but the build will also work on older architectures.
