LibreMesh packages
LibreMesh project includes the development of several tools used for
deploying libre/free mesh networks.
The firmware (the main piece) will allow simple deployment of auto-configurable,
yet versatile, multi-radio mesh networks. Check the Network Architecture to
see the basic ideas.
We encourage each network community to create its firmware profile on
network-profiles repository and build the images locally.
Supported hardware
In this page we provide a list of requirements that ensure you to have a
working LibreMesh node on your router. This list comes with no warranties: read
carefully the model-specific instructions on OpenWrt wiki and be
extra-careful when flashing your routers!
Building a Firmware Image on Your PC
Building the stable release LibreMesh 2020.1
Using the BuildRoot
The BuildRoot will cross-compile the whole OpenWrt and the LibreMesh packages on your computer, so it will take approx 10 GB of disk space and a few hours of compilation time.
For compiling LibreMesh firmware with this method, you can follow these instructions.
Using the ImageBuilder
The ImageBuilder method is not available for the stable release.
Building the experimental firmware
The experimental code still has serious issues that have to be solved, use it only for developing or debugging.
Using the BuildRoot
As explained above, in the instuctions on the website you will find where to specify the version of the code to compile.
Using the ImageBuilder
The ImageBuiler will download pre-compiled parts of the OpenWrt releases, and add the pre-compiled LibreMesh packages, so it is much faster than the BuildRoot method (but less practical if you want to develop some new features modifying LibreMesh source code).
Start an ImageBuilder of your choice, for example ath79-generic if your device is supported within it, use containers for an easier setup:
mkdir ./images/
docker run -it -v $(pwd)/images:/images/ ghcr.io/openwrt/imagebuilder:ath79-generic-v22.03.5
If your device is not part of ath79-generic profiles, you can replace it with another - combination. For knowing which target and subtarget is best suited for your router, check out the page about it in the OpenWrt's Table of Hardware.
Within the container, add the lime-packages feed:
echo "src/gz libremesh https://feed.libremesh.org/master" >> repositories.conf
echo "untrusted comment: signed by libremesh.org key a71b3c8285abd28b" > keys/a71b3c8285abd28b
echo "RWSnGzyChavSiyQ+vLk3x7F0NqcLa4kKyXCdriThMhO78ldHgxGljM/8" >> keys/a71b3c8285abd28b
Ideally add your own lime-community files within the container in the folder
./files/etc/config/. To find possible options consult the
lime-example.txt file. It is also possible to mount an existing
lime-community file directly via -v $(pwd)/lime-community:/builder/files/etc/config/lime-community.
Now create an image of your choice, to see the names of supported profiles run
make info first.
make image PROFILE=ubnt_unifi PACKAGES="lime-system lime-proto-babeld lime-proto-batadv lime-proto-anygw lime-hwd-openwrt-wan -dnsmasq" BIN_DIR=/images FILES=files
Your images should be available outside of the container in the ./images/ folder
Possible errors from the ImageBuilder
If you get a docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. error, means that you don't have Docker's daemon running. Make sure you have docker installed and start its daemon with systemctl start docker.service.
If you get a opkg_download: Check your network settings and connectivity. error, both check the connectivity and make sure that the firewall rules of your computer allow the container to reach the internet.
Testing
LibreMesh has unit tests that help us add new features while keeping maintenance
effort contained.
To run the tests simply execute ./run_tests.
Please read the [Unit Testing Guide] for more details about
testing and how to add tests to LibreMesh.
