Something seems to have screwed up your build. The output should be
something like this:

[tgraf at lsx libnl]$ src/genl-ctrl-list 
0x0010 nlctrl version 2
0x0011 NLBL_MGMT version 3
0x0012 NLBL_CIPSOv4 version 3
0x0013 NLBL_UNLBL version 3
0x0014 acpi_event version 1
0x0015 thermal_event version 1
0x0016 VFS_DQUOT version 1
0x0017 TASKSTATS version 1
0x0018 NET_DM version 2
[tgraf at lsx libnl]$ 

This allows you to verify whether your kernel side generic netlink
family was successfully registered.

It even allows you to list the operations that you have registered:

[tgraf at lsx libnl]$ src/genl-ctrl-list -f details
