n-dhcp4

Dynamic Host Configuration Protocol for IPv4

The n-dhcp4 project implements the IPv4 Dynamic Host Configuration Protocol as defined in RFC-2132+.

Project

Requirements

The requirements for this project are:

  • Linux kernel >= 3.19
  • libc (e.g., glibc >= 2.16)

At build-time, the following software is required:

  • meson >= 0.41
  • pkg-config >= 0.29

Build

The meson build-system is used for this project. Contact upstream documentation for detailed help. In most situations the following commands are sufficient to build and install from source:

mkdir build
cd build
meson setup ..
ninja
meson test
ninja install

No custom configuration options are available.
