[Kea-users] Getting the interface name in hooks

[Gokulakrishnan Gopalakrishnan]

Thanks Marcin, I just did what you mentioned in the code and printed
*iface_configuation->str()* and it prints an empty array interface.
Probably because I didn't link the hook user_chk with *libkea-dhcpsrv*.
I tried linking *libkea-dhcpsrv *by adding

libdhcp_user_chk_la_LIBADD  += $(top_builddir)/src/lib/hooks/libkea-dhcpsrv.la

in src/hooks/dhcp/user_chk/Makefile.am and did a make.

I'm getting automake-1.14: command not found. Every time editing
Makefile.am, I'm getting this error. Am I doing the linking correctly?
Am I missing something here? Please correct me if I'm wrong
