This script will patch current 21.02 branch of OpenWRT with Mikrotik hAP ac2 PR 3073, Mikrotik cAP ac PR 4055, and Mikrotik hAP ac lite PR 3348.
It's all done through Docker images/containers so you need to have Docker installed.
To build OpenWRT for Mikrotik hAP ac2 execute:
./build.sh hap-ac2
For Mikrotik cAP ac execute:
./build.sh cap-ac
And for Mikrotik hAP ac lite: This currently does not work due to a missing upstream fix!
./build.sh hap-ac-lite
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.
