openwrt-mikrotik

This script builds OpenWRT via Docker images/containers, i.e. Docker is your only build dependency.

Tested versions of OpenWRT:

• 23.05.0

Configuring

The default target is ipq40xx for Mikrotik hAP ac2 and cAP ac.

You can add new targets by creating files in configs, similar to ipq40xx. A config will get merged with common.txt which basically contains all the packages you'd like to have in the image.

To create new configs use

./build.sh docker config

which runs OpenWRTs menuconfig. Use the resulting output to create new config files with the name of your choice.

Building firmware images

To build OpenWRT execute:

./build.sh

The default target is ipq40xx. If you'd like to use a different target run the script like this:

TARGET=ath79 ./build.sh

This will use configs/ath79.txt as config.

You can also build multiple targets at the same time:

TARGET=ath79,rtl838x,ipq40xx ./build.sh

To build the master branch of OpenWRT use:

OPENWRT_VERSION=master ./build.sh

To build a tagged 23.05.0 OpenWRT version which supports hAP ac2 and cAP ac use for example:

OPENWRT_VERSION=v23.05.0 ./build.sh

To build a branch, use the branch name, e.g.:

OPENWRT_VERSION=openwrt-23.05 ./build.sh

After the script finishes the resulting target builds are copied from the Docker container to the build folder in the local file system. The resulting Docker images/containers will be up to 12G each in size and can be deleted after the build finished.

The whole process takes about 45 minutes on a modern CPU.

To clean the build files and force a fresh next build execute:

./build.sh clean

To get shell access to the build environment (useful for debugging):

./build.sh shell
