Package: iptables-netflow-dkms
Version: 2.6-7.2
Severity: important
Tags: upstream
Hi,
iptables-netflow-dkms fails to build a module for Linux 6.19 in
experimental:
DKMS (dkms-3.2.2) make.log for ipt-netflow/2.6 for kernel 6.19-amd64 (x86_64)
Fri Jan 16 09:01:36 UTC 2026
Running the pre_build script
# command: cd /var/lib/dkms/ipt-netflow/2.6/build/ &&
/var/lib/dkms/ipt-netflow/2.6/build/./configure
--from-dkms-conf=/lib/modules/6.19-amd64/build --prefix=/usr
--includedir=/usr/include --libdir=/usr/lib/x86_64-linux-gnu
--ipt-bin=/usr/sbin/iptables-legacy --enable-natevents --enable-snmp-rules
--enable-macaddress --enable-vlan --enable-direction --enable-sampler
--enable-physdev --enable-promisc --promisc-mpls
Module version: 2.6
Iptables binary version: no iptables binary found
Xtables version: 1.8.11 (detected from pkg-config)
Check for working gcc: Yes (x86_64-linux-gnu-gcc-15)
Checking for presence of xtables.h... Yes (using ipt-inc)
Iptables include flags: -I/usr/include (user specified)
Iptables module path: /usr/lib/x86_64-linux-gnu/xtables (user specified)
Searching for net-snmp-config... No.
Searching for net-snmp agent... No.
Assuming you don't want net-snmp agent support.
Otherwise do: apt-get install snmpd libsnmp-dev
Creating Makefile.. done.
If you need some options enabled run ./configure --help
Now run: make all install
