https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292844 Bug ID: 292844 Summary: science/py-scipy builds but import of some features causes an error Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: python@FreeBSD.org Reporter: russo@bogodyn.org Flags: maintainer-feedback?(python@FreeBSD.org) Assignee: python@FreeBSD.org Recent changes to the science/py-scipy port enabled it to build with cython >= 3.2, but unfortunately while it does build, trying to use the package leads to an attempt to reference an undefined symbol I am uncertain what the *correct* way to fix the problem is, but I was able to restore the function by changing the USES line to specify cython0 (which I know to be the wrong fix). But as it stands, while it builds fine with the current cython, scipy as installed by the port without modification is unusable in my application. uname -a: FreeBSD xxx.xxx 14.3-STABLE FreeBSD 14.3-STABLE stable/14-n273238-c95f96dea30a GENERIC amd64 Expected behavior: > python >>> from scipy import interpolate >>> That is, the import just works. Behavior when port is installed without modification: > python >>> from scipy import interpolate Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.11/site-packages/scipy/__init__.py", line 189, in __getattr__ return _importlib.import_module(f'scipy.{name}') ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/site-packages/scipy/interpolate/__init__.py", line 167, in <module> from ._interpolate import * File "/usr/local/lib/python3.11/site-packages/scipy/interpolate/_interpolate.py", line 9, in <module> import scipy.special as spec File "/usr/local/lib/python3.11/site-packages/scipy/special/__init__.py", line 772, in <module> from . import _ufuncs File "_ufuncs.pyx", line 1, in init scipy.special._ufuncs ImportError: /usr/local/lib/python3.11/site-packages/scipy/special/_ufuncs_cxx.cpython-311.so: Undefined symbol "wrap_PyUFunc_getfperr" >>> A quick web search turned up very little of help, but did suggest exactly the incompatibility of newer cython and possibly a problem with the use of the deprecated setup.py instead of meson for building (I'm just parroting what I read, not suggesting I know this to be a solution). -- You are receiving this mail because: You are the assignee for the bug.home | help
