We maintain our [own Gluon repository](https://gitlab.freifunk-stuttgart.de/firmware/gluon) to make it easy to apply patches to Gluon.
Gluon versions used for specific Stuttgart Freifunk Firmware builds:
Gluon is maintained as a [Git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules) in the `gluon` subdirectory.
* ffs-1.7: v2018.2.3-ffs0.1
* ffs-1.6: v2018.2.2-ffs0.1
## Building
* ffs-1.4: v2017.1.5 (LEDE)
* ffs-1.3: v2016.2.7 + 1340 mtu
Because we maintain Gluon as a submodule, some special steps are required:
* ffs-1.2: v2016.2.6 + ffs-set-segment dns fix + 1312 mtu
* ffs-1.1: v2016.2.6 + ffs-set-segment dns fix
- clone this repository with `--recurse-submodules`: ```git clone --recurse-submodules https://gitlab.freifunk-stuttgart.de/firmware/site-ffs.git```
* ffs-1.0: v2016.2.5
* If you already clonsed this repo, initalize submodules using `git submodule update --init .`
* ffs-0.9: v2016.2.1
- run `buildall.sh` to build all targets
* ffs-0.8: v2016.2
* ffs-0.7: v2016.1.3
### Download Cache
* ffs-0.6: v2016.1
* ffs-0.5: v2015.1.2
We maintain a [cache of all downloaded files during the build](https://gitlab.freifunk-stuttgart.de/firmware/ffs-openwrt-dl-cache).
## Committing
When changing something in Gluon, keep in mind - besides making the changes in the Gluon repository - you also need to make a commit here that updates the `gluon` submodule. You can do so by:
- changing to the `gluon` subdirectory,
- making your changes,
- commit and push them to the Gluon repository,
- going back to the `site-ffs` directory,
-`git add gluon` and then `git commit` to create a commit which updates the Gluon version in the site-ffs repo.
## Automatic Gluon Update
Minor version updates of Gluon are usually very easy to do. Therefore, we have a daily job which checks for a new minor version of Gluon and performs an [automatic update](https://gitlab.freifunk-stuttgart.de/firmware/ffs-pipeline-nightly) if one is available.
## Other repositories
We have a [repository with our custom packages](https://gitlab.freifunk-stuttgart.de/firmware/gluon-packages).
There are [several other repos related to the firmware build](https://gitlab.freifunk-stuttgart.de/firmware).
