How to add udhcpd in yocto?

Question

I want to set my wireless interface (mlan0) to access point mode. I have hostapd in /usr/sbin. But I don't have udhcpd.

I have udhcpc in /sbin though. I checked my busybox.bb file and found CONFIG_UDHCPD=y in defconfig. Not sure what i am missing here.

dhcp recipe provides different packages:

poy/meta/recipes-connectivity/dhcp/dhcp.inc:

PACKAGES += "dhcp-libs dhcp-server dhcp-server-config dhcp-client dhcp-relay dhcp-omshell"

You just need to add:

IMAGE_INSTALL_append = " dhcp-server"

EDIT

Busybox provides udhcpd in separate package, so you need to add:

IMAGE_INSTALL_append = " busybox-udhcpd"

this package only installs busybox-udhcpd binary under /etc/init.d/ if CONFIG_UDHCPD=y
