Skyfield on an Core2 Duo

[Chris Alemany]

Hi all,

I just updated to Debian 13 and it threw weewx for a bit of a loop.

PyEphem doesn’t seem to function out of the box and installing Skyfield is failing on start up with numpy complaining:

CRITICAL __main__: Caught unrecoverable exception:
Mar 05 15:26:53 footiMac weewxd[227359]: CRITICAL __main__: **** NumPy was built with baseline optimizations:
(X86_V2) but your machine doesn't support:
(X86_V2).

Is it possible to compile numpy for my processor?
