[ipseokri]

Building modules, stage 2. MODPOST 6 modules ERROR: "geneve_dev_create_fb" [/home/odroid/Downloads/ovs/datapath/linux/vport-geneve.ko] undefined!

I'm tyring to compile on odroid xu4 with kernel version 5.4.167+ and ovs version 2.15.4.

But When I build the kernel module in ordroid, there is an error about undefined Error.

I'm trying to compile this for three weeks.

please give any idea solving this problem.

Hi. I'm having the same issue. Is there any updates or workaround regarding this issue? Thanks

The kernel module from OVS source tree is deprecated since OVS 2.15 and doesn't receive updates for support of new kernels, including new stable versions of kernels and kernels provided by distributions, since these can be significantly modified.

The kernel module shipped with 5.4 kernel should be modern enough to use, so you should not need to build the module from OVS sources.

BTW, OVS 2.15 reached end of support quite some time back, the oldest supported version is OVS 2.17.

I don't remember exactly, but as far as I can remember, it was due to the influence of ovs installed on existing Linux. So, if you build with all the preinstalled kernel modules removed, it will work out.

$ config_file="/etc/depmod.d/openvswitch.conf"
$ for module in datapath/linux/*.ko; do modname="$(basename ${module})"; echo "override ${modname%.ko} * extra" >> "$config_file"; echo "override ${modname%.ko} * weak-updates" >> "$config_file"; done
$ depmod –a
$ /sbin/modprobe openvswitch
$ make modules_install

You have to try this. It will work with you! 🙂
