Hello all, I am using this mailing list as the last chance to get a solution to my problem. I hope my simple question is not going to bother you too much. I am trying to compile and run the simpliest program that uses libipq, the man example program. When I try to compile it, I get the following error code: In file included from example.c:2: /usr/include/linux/netfilter.h:55: error: field ‘in’ has incomplete type /usr/include/linux/netfilter.h:56: error: field ‘in6’has incomplete type It looks like there is a problem with the netfilter header, that is not able to load the in.h and in6.h librairies. I installed all the necessary tools: iptables 1.4.7 libnetfilter_queue 0.0.17 (the actual successor of ip_queue) libnfnetlink 1.0.0 I am using Ubuntu 9.10, with the 2.6.31-14 kernel. I of course searched for any solutions, and found that this problem has been encountered in the past. However, I didn't get any relevant information. Thanks in advance for your precious advices.
