Hello, tried this on Gentoo, emerged all the dependencies, installation goes OK. But I cannot start opensnitch due to an error:

I cant reproduce this but I do get some interesting compiler warnings from python-netfilterqueue related to this.

@robertvalik Can you try to apply this patch to python-netfilterqueue and see if that fixes it for you? If it does I'm going to send a PR upstream.

gled-rs commented 7 years ago

I can confirm the patch fixes the issue ( I had the same problem on gentoo ).

Pull request sent upstream: https://github.com/kti/python-netfilterqueue/pull/32

robertvalik commented 7 years ago

@gled-rs Would you be so kind to help me out - how to apply the patch? What package?

adisbladis commented 7 years ago

@robertvalik You are presumably getting python-netfilterqueue from the Pentoo overlay.

That one is using Portage EAPI 6 which should allow you to apply user patches easily. Here is a good starting point: https://wiki.gentoo.org/wiki//etc/portage/patches#Adding_user_patches

robertvalik commented 7 years ago

@adisbladis Nope, actually, I cannot find any python-netfilterqueue in my portage tree (and overlays). I believe that the setup.py script installed NetfilterQueue. Am I mistaken, should I get the Pentoo overlay and install the pakage from there?

gled-rs commented 7 years ago

I just compiled from the source, applied the patch and installed it from there. Did not used pentoo overlay for that.

robertvalik commented 7 years ago

The NetfilterQueue package was installed using pip. I removed it and installed a patched version. Openstitch starts now. Thanks!
