Error compile ndpi-netfilter

[jerric12]

Hi, I've installed ntopng/ndpi on a Debian Jessie and it works fine. I need to associate with Netfilter. I tried to compile ndpi-netfilter with your instructions. I have these errors. Do you have an idea ? Can you help me please ? Thanks a lot

What is the nDPI library used in this compilation? This build was tested with "nDPI.tar.gz" included here in this project - you will have problems with newer nDPI versions.

First, thanks a lot for your answer ans sorry for my englis, i'm french ;-) I installed nDPI using "git clone https://github.com/ntop/nDPI.git" form http://www.ntop.org/get-started/download/. i think it's nDPI 1.6. It works with nf_conntrack_netlink, no ? I've built a new kernel (3.16) with nf_conntrack_netlink enabled. I tried a lot of solutions but without success

hi... I'm Brazilian, my native language is portuguese.

You can't build this ndpi-netfilter version with latest nDPI lib or source - and you did this with "git clone" command.

Follow this steps (using nDPI.tar.gz): https://github.com/betolj/ndpi-netfilter/blob/master/ndpi.install

This version works with nf_conntrack_netlink, so this doesn't require kernel patch.

Hi, You know what ? If you were near me, il would give you a big kiss LOL IT WORKS VERY WELL !!! Thanks a lot I was working on this project for 2 months with the ewildgoose's project. It doesn't work now. I found your project recently. The problem was the last version of nDPI. All was writen in your ndpi.install !!! In french, we said : "Je suis un imbécile" I tried too many solutions and finally i was lost. Thanks again for answered me so quickly. Have a very nice day Jérôme
