I ran into an issue with https://github.com/nbruin/RiemannTheta where
installing it into modern sage completes without an error but where I get:
sage: import riemann_theta.riemann_theta
ImportError:
/usr/local/sage/sage-git/local/var/lib/sage/venv-python3.13/lib64/python3.13/site-packages/riemann_theta/riemann_theta.cpython-313-x86_64-linux-gnu.so:
undefined symbol: pari_err
Clearly, libpari doesn't get linked. Previously it did, so this is probably
due to some tightening of dependency determination in cython or python's
setup machinery.
The setup.py for this project is below. This used to work. Is there an
obvious way in which I should change it? Particularly is there something
sage-specific that can help here? The package in question really depends
quite closely on a lot of sage so it would need to be built within its venv
anyway.
--------------------------------------
import setuptools
from Cython.Build import cythonize
import numpy
with open("README.md", "r") as fh:
long_description = fh.read()
setuptools.setup(
name='RiemannTheta',
version="1.0.0",
author="Nils Bruin, Sohrab Ganjian",
author_email="[email protected]",
license="GPL2+",
description="Evaluate Riemann Theta function numerically in Sagemath",
long_description=long_description,
long_description_content_type="text/markdown",
url="",
packages=setuptools.find_packages(),
ext_modules=cythonize("riemann_theta/riemann_theta.pyx"),
include_dirs=[numpy.get_include()],
zip_safe=False,
)
-----------------------------------------------
I guess there need to be some "libraries" and possibly "library_dirs" added
to the config but hardcoding them is probably not a good idea. Suggestions?
(ChatGPT suggests running "pari-config" but I think it just came up with
that because it looked convenient)
There may be other third party packages out there that quietly broke due to
some backwards incompatible changes in the python/sage build system.
