symbol not found in flat namespace '_ch_alloc_scratch'

[savinoda]

Hi all, I'm installing hyperscan on Mac M1 with pip install hyperscan and I get this error:

File "/Users/user/miniconda3/envs/env/lib/python3.10/site-packages/hyperscan/__init__.py", line 3, in <module> from hyperscan._ext import * # noqa: F401, F403 ImportError: dlopen(/Users/user/miniconda3/envs/env/lib/python3.10/site-packages/hyperscan/_ext.cpython-310-darwin.so, 0x0002): symbol not found in flat namespace '_ch_alloc_scratch'

Is this yet not supported on ARM architecture?

hmm iirc the tests passed on the ARM GH actions runner that built the wheels but I'll take a look

Thanks, please let me know if you need anything from my side. I've not done anything crazy: just pip install and import it

I'm having the same issue here, on a fresh new environment (On a Macbook Pro M2 Pro):

❯ pdm init
❯ pdm add hyperscan

Importing hyperscan immediately fails.

❯ pdm run python

LMK if you want me to provide further information/tests

sorry for the delay, could you please try one of the *_macosx_arm64 wheels from here? i think i might need to bump the release since PyPI doesn't let me replace existing versions of artifacts, so would be good to get a smoke test, although i think it should work now as the previous runner for the arm64 builds wasn't actually arm64 🤦

[darvid]

tested 3.12 on my M2 mbp so will push later assuming no further issues on macOS/arm64

[savinoda]

Hi is the patch being merged soon?

[clement-tourriere]

Tested too on mac M1, and it's working fine. Waiting for the release now :). Thank you for your incredible work !

No worries, just was able to make it work as well. Thanks for the work!

@darvid would you please push this?

sorry for the delay

latest version is 0.7.7 (yep 7 extra patch increments) because i was 🤬 getting semantic-release working (for future me/maintainers/collaborators, manually publishing all these x-platform artifacts is a massive pita)
