NetfilterQueue not installing about python-netfilterqueue HOT 3 CLOSED

@winterrdog You need to install the libnetfilter_queue development headers. On Debian or Ubuntu this is apt-get install libnetfilter-queue-dev, not sure the appropriate package on other distros.

@borisarloff I just pushed an update that fixes compilation on 3.9 (and 3.10). It will be released to PyPI shortly.

@riddhiman1 The URL in the readme was outdated; I fixed it, try now. https://github.com/oremanj/python-netfilterqueue

from python-netfilterqueue.

I am experiencing the same issue with python3.9
I don't know why it is happening. This is the reason i see in the traceback, it maybe that a certain C header file is missing:
**netfilterqueue.c:437:10: fatal error: libnfnetlink/linux_nfnetlink.h: No such file or directory
437 | #include "libnfnetlink/linux_nfnetlink.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
error: command '/usr/bin/x86_64-linux-gnu-gcc' failed with exit code 1

ERROR: Failed building wheel for netfilterqueue**

This happened when i used "pip3 install netfilterqueue" to install it

from python-netfilterqueue.

The problem is with CPython for Python 3.9 changes. PyTypeObject.tp_print was removed but not from the netfilterqueue.c file, hence it cannot compile crrectly under Python 3.9. You need to revert to Python 3.8 or patch the netfilterqueue.c file.
