Prerequisites

Install a few dependencies

  apt-get install gawk libncurses-dev

Build this from the OpenWRT source snapshot for your target. E.g. for the apu2 (x86_64):

  wget https://downloads.cdn.openwrt.org/snapshots/targets/x86/64/openwrt-sdk-x86-64_gcc-8.4.0_musl.Linux-x86_64.tar.xz

For the raspberry pi 4:

  wget https://downloads.openwrt.org/snapshots/targets/bcm27xx/bcm2711/openwrt-sdk-bcm27xx-bcm2711_gcc-8.4.0_musl.Linux-x86_64.tar.xz

For the raspberry pi 3 b+:

  wget https://downloads.cdn.openwrt.org/snapshots/targets/bcm27xx/bcm2710/openwrt-sdk-bcm27xx-bcm2710_gcc-8.4.0_musl.Linux-x86_64.tar.xz

Build

Unpack the OpenWRT SDK

  tar xJf openwrt-sdk-x86-64_gcc-8.4.0_musl.Linux-x86_64.tar.xz
  cd openwrt-sdk-x86-64_gcc-8.4.0_musl.Linux-x86_64

Add the massmessh source to the feeds file:

  echo "src-git massmesh https://github.com/massmesh/mm-toolbox.git" >> feeds.conf.default

If you want to track another branch, add ;branchname to the url, e.g. for the 'dev' branch:

   echo "src-git massmesh https://github.com/massmesh/mm-toolbox.git;dev" >> feeds.conf.default

Update the feeds

  ./scripts/feeds update

Install the massmesh feeds

  ./scripts/feeds install autoygg-go mm-cli # for the massmesh packages

Generate a basic .config file. Open menuconfig and then select 'Global build settings' and disable 'Cryptographically sign package lists'. Exit and save config.

  make menuconfig

Finally, build (adjust the number of cores to something reasonable for your build box):

  make -j4
