Installing Suricata 6.0.1 with PF_RING on CentOS8

Hello everyone,

after a problematic install, I thought of writing a little guide to hopefully ease your pain while compiling Suricata on CentOS8 with PF_RING.
During ./configure --enable-pfring phase I was always hit by an error

checking for pfring_open in -lpfring... yes

   ERROR! --enable-pfring was passed but the library version is < 6, go get it

despite the fact I had PF_RING installed.

So, to start from the beginning, I installed PF_RING using the provided ntop guide

sudo wget -O /etc/yum.repos.d/ntop.repo

rpm -ivh 
rpm -ivh 
yum install dnf-plugins-core 
dnf config-manager --set-enabled powertools 
dnf config-manager --set-enabled remi 

yum erase zeromq3 
yum clean all 
yum update 
yum install pfring-dkms n2disk nprobe ntopng cento 

and then I have used configure command again with additional CFLAGS parameter “-D_GNU_SOURCE” and continued in compilation as normal without errors. For me, missing -D_GNU_SOURCE flag was causing errors in config.log as

unknown type name 'u_int'; did you mean 'int'
unknown type name 'u_char'; did you mean 'char'

./configure command and the rest of the compilation:

LIBS="-lrt" ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-pfring CFLAGS="-D_GNU_SOURCE"

sudo make install-full

You might also need to execute these commands as well:

grep "/usr/lib" /etc/ > /dev/null || echo "/usr/lib" | sudo tee -a /etc/ > /dev/null
sudo ldconfig

If someone can get me feedback on this, I’ll be glad, hopefully I have not missed anything. Alternatively, while dealing with this problem, I followed a guide from @jonny5 . I do not think it has resolved my problem but maybe it can put somebody in a correct direction if this guide did not.
