BUILDING.md

Building the image

Prerequisites

• some kind of Linux distro (tested on Arch Linux and Ubuntu)
• docker
• git

Download development container

All the compiling is done inside a running container in order to mitigate differences between different Linux distributions.

All the commands are expected to be run in some kind of work directory, e.g. /home/user/work

First, we need to pull it from docker hub:

docker pull lpnplant/openwrt-docker

We can also build it manually using the Dockerfile from our repository.

We will need the script to start the image:

git clone https://github.com/lpn-plant/openwrt_docker.git

Build

First, let's clone the repository:

git clone https://github.com/lpn-plant/openwrt.git

Let's start the container:

./openwrt_docker/scripts/run_docker.sh openwrt

And inside the container:

./scripts/feeds update luci
./scripts/feeds install luci luci-app-watchcat luci-app-lorawan
cp configs/apu_config .config
make oldconfig
make

• luci-app-watchcat is LuCI service widget for watchcat
• luci-app-lorawan is LuCI service widget for LoRaWAN configuration

This should be the compilation output:

 make[1] world
 make[2] toolchain/compile
 make[2] package/cleanup
 make[3] -C toolchain/binutils compile
 make[3] -C toolchain/gdb compile
 make[3] -C toolchain/fortify-headers compile
 make[3] -C toolchain/yasm compile

 ...

 make[2] package/install
 make[2] target/install
 make[3] -C target/linux install
 make[2] package/index
 make[2] checksum

After the build, the images are available in bin/targets/x86/64-glibc.
