Meson build on Arch/Void: Missing 'cremona_mini.db' #40144
Description
Summary
When building SageMath with Meson on Arch and Void Linux, a few docstests fail to find the cremona db:
Traceback (most recent call last):

'cremona_mini.db' not found in any of ['/github/home/.sage/db/cremona', '/github/home/.local/share/uv/python/cpython-3.13.3-linux-x86_64-gnu/share/sagemath/cremona', '/github/home/.local/share/uv/python/cpython-3.13.3-linux-x86_64-gnu/share/cremona']
Although the relevant package is installed.
I assume meson should set CREMONA_LARGE_DATA_DIR correctly. But what's the best way to find where the db is installed on the system?
Additional Context
- OS: Arch Linux, Void Linux
- Build system: Meson
