NetfilterQueue for Python 3.9
borisarloff opened this issue · 5 comments
NetfilterQueue 0.8.1 does not compile for Python 3.9. CPython 3.9 had changes made, with one specific change impacting NFQ. Refer to Python Issue 37250 PyTypeObject.tp_print removed.
The following change removed PyTypeObject.tp_print and replaced it with PyTypeObject.tp_vectorcall_offset: commit aacc77fbd77640a8f03638216fa09372cc21673d
Accordingly, I have monkeypatched netfilterqueue.c to compile under Python 3.9. File is here attached.
netfilterqueue.txt
File renamed from .c to .txt for upload, please rename it back to .c.
Hi, may I ask how to compile/use this netfilterqueue.c to install netfilterqueue Python package?
I am running python 2.7.18 and python 3.9.9 .
I tried replacing you code from netfilterqueue.c into original and tried to install it. It was unsuccessful. Can you advice me on installation please.
following is the Error:
python setup.py install

I tried this and it worked for Python 3.9.2+:
sudo apt-get install build-essential python3-dev libnetfilter-queue-dev

gunzip [filename]
tar xvf [filename]
cd [filename]
rm netfilterqueue.c
sudo python3 ./setup.py install

It seems this worked for me. Thanks!
Current master should build on 3.9 and I'll be releasing to PyPI shortly.
