===== Build Firmware =====

We usually use Debian and Ubuntu but many other distributions should also work. It is also possible to build on OSX. Building firmware directly on a Windows platform is not supported. However, if all you have available is a windows machine then we would recommend to set up a linux based virtual machine. //**Note: the following build was made on Ubuntu 16.04.5 LTS running 4.15.0-43 kernel.**//

----

Once you have a Linux OS running install the following prerequisite packages (some are optional):

  sudo apt-get update
  sudo apt-get install git git-doc subversion build-essential flex wget gawk unzip man file time python2.7 zlib1g-dev libssl-dev libncurses5-dev

Get the latest sources from 8devices OpenWRT branch:

  git clone --branch openwrt-18.06-rtkmipsel-3.18 https://github.com/8devices/openwrt-8devices.git kinkan
  cd kinkan

Update and install feeds:

  ./scripts/feeds update -a
  ./scripts/feeds install -a

Copy Kinkan config to build config:

  cp config_kinkan_minimal .config
  make defconfig

Add additional packages that you need (optional):

  make menuconfig

Build using several cores **make -j[n]** where **[n]** is equal to amount of processor cores or threads:

  make -j4

Building is a CPU heavy process and may take a long time depending on your CPU capabilities.

Once finished the compiled firmware image ending with ''.bin'' will be placed under ''bin/targets/rtkmipsel/rtl8197f'' directory.
