When build DHCP from sources and trying to run the DHCP server, failing with ERROR. Any ideas what could the issue, something related how build from sources or something else is missing? No issues if install the DHCP Server from package(sudo apt-get install isc-dhcp-server).

ERROR:

Ubuntu: 16.04.6 LTS (Xenial Xerus)

Script to build DHCP from sources:

#!/usr/bin/env bash

Define variable


DHCP_VER="v4_4_2"


Install libary for build DHCP server


sudo apt update && sudo apt -y full-upgrade
sudo apt -y install libtool build-essential autoconf automake g++


Preparation


if ! [ -d ~/build ]; then
    mkdir ~/build
fi


cd ~/build


git clone https://gitlab.isc.org/isc-projects/dhcp.git -b ${DHCP_VER}


cd ~/build/dhcp


autoreconf -i


CFLAGS="-D_PATH_DHCLIENT_SCRIPT='&quot;/sbin/dhclient-script&quot;'             

        -D_PATH_DHCPD_CONF='&quot;/etc/dhcp/dhcpd.conf&quot;'                   

        -D_PATH_DHCLIENT_CONF='&quot;/etc/dhcp/dhclient.conf&quot;'"


./configure --prefix=/usr                                           

            --sysconfdir=/etc/dhcp                                  

            --localstatedir=/var                                    

            --with-srv-lease-file=/var/lib/dhcpd/dhcpd.leases       

            --with-srv6-lease-file=/var/lib/dhcpd/dhcpd6.leases     

            --with-cli-lease-file=/var/lib/dhclient/dhclient.leases 

            --with-cli6-lease-file=/var/lib/dhclient/dhclient6.leases


Make and install DHCP


make >make.out 2>&1
make install

Missing configuration property. Please add --enable-paranoia to the configure flags.

./configure --enable-paranoia
            --prefix=/usr                                           \
            --sysconfdir=/etc/dhcp                                  \
            --localstatedir=/var                                    \
            --with-srv-lease-file=/var/lib/dhcp/dhcpd.leases        \
            --with-srv6-lease-file=/var/lib/dhcp/dhcpd6.leases      \
            --with-cli-lease-file=/var/lib/dhclient/dhclient.leases \
            --with-cli6-lease-file=/var/lib/dhclient/dhclient6.leases
