[Keepalived-devel] keepalived-2.0.7 --with-kernel-dir

[Rafał S. <rsa...@mp...>]

Hey ,

I have two problems.
after running ./configure --with-kernel-dir = /usr/src/ linux-4.14.76
I get
configure: error: Missing / unusable kernel header file <linux/netlink.h>

Workaround
ln -s  /usr/src/linux-4.14.76 /usr/src/linux

Second one.
when i try to compile with --enable-snmp
  i get

i found that nla_get_s32 is defind in 1 files as a function:
include/net/netlink.h at kernel
what  i'm  missing ? Withouth enable-snmp keepalived can compile.
