To build Gluon, after checking out the repository change to the source root directory
|
|
to perform the following commands:
|
|
|
|
git clone git://github.com/freifunk-gluon/site-ffhl.git site # Get the Freifunk Lübeck site repository - or use your own!
|
|
make update # Get other repositories used by Gluon
|
|
make # Build Gluon
|
|
|
|
When calling make, the OpenWRT build environment is prepared/updated. To rebuild
|
|
the images only, just use:
|
|
|
|
make images
|
|
|
|
The built images can be found in the directory `images`.
|
|
|
|
For the build reserve 6GB of disk space. The build requires packages
|
|
for `subversion`, ncurses headers (`libncurses-dev`) and zlib headers
|
|
(`libz-dev`).`
|
|
|
|
|
|
There are three levels of `make clean`:
|
|
|
|
make clean
|
|
|
|
will only clean the Gluon-specific files;
|
|
|
|
make cleanall
|
|
|
|
will also call `make clean` on the OpenWRT tree, and
|
|
|
|
make dirclean
|
|
|
|
will do all this, and call `make dirclean` on the OpenWRT tree. Of these, `make cleanall`
|
|
is the most useful as it ensures that the kernel and all packages are rebuilt (which won't
|
|
be done when only patches have changed), but doesn't rebuild the toolchain unnecessarily.
|
|
|
|
So all in all, to update and rebuild a Gluon build tree, the following commands should be used:
|
|
|
|
git pull
|
|
(cd site && git pull)
|
|
make update
|
|
make cleanall
|
|
make
|
|
|
|
|
|
# The autoupdater
|
|
|
|
Gluon contains an automatic update system which can be configured in the site configuration.
|
|
|
|
By default, the autoupdater is disabled (as it is usually not helpful to have unexpected updates
|
|
during development), but it can be enabled by setting the variable GLUON_BRANCH when building
|
|
to override the default branch set in the set in the site configuration.
|
|
|
|
A manifest file for the updater can be generated with `make manifest`. A signing script (using
|
|
ecdsautils) can by found in the `contrib` directory.
|
|
|
|
A fully automated nightly build could use the following commands:
|
|
|
|
git pull
|
|
(cd site && git pull)
|
|
make update
|
|
make cleanall
|
|
make -j5 GLUON_BRANCH=experimental
|
|
make manifest GLUON_BRANCH=experimental
|
|
contrib/sign.sh $SECRETKEY images/sysupgrade/experimental.manifest
|
|
cp -r images /where/to/put/this/experimental
|
|
mv /where/to/put/this/experimental/experimental.manifest /where/to/put/this/experimental/manifest
|
|
|
|
|
|
# Development
|
|
|
|
**Gluon IRC channel: `#gluon` in hackint**
|
|
|
|
To update the repositories used by Gluon, just adjust the commit IDs in `modules` and
|
|
rerun
|
|
|
|
make update
|
|
|
|
`make update` also applies the patches that can be found in the directories found in
|
|
`patches`; the resulting branch will be called `patched`, while the commit specified in `modules`
|
|
can be refered to by the branch `base`.
|
|
|
|
make unpatch
|
|
|
|
sets the repositories to the `base` branch,
|
|
|
|
make patch
|
|
|
|
re-applies the patches by resetting the `patched` branch to `base` and calling `git am`
|
|
for the patch files. Calling `make` or a similar command after calling `make unpatch`
|
|
is generally not a good idea.
|
|
|
|
After new patches have been commited on top of the patched branch (or existing commits
|
|
since the base commit have been edited or removed), the patch directories can be regenerated
|
|
using
|
|
|
|
make update-patches
|
|
|
|
If applying a patch fails because you have changed the base commit, the repository will be reset to the old `patched` branch
|
|
and you can try rebasing it onto the new `base` branch yourself and after that call `make update-patches` to fix the problem.
|
|
|
|
Always call `make update-patches` after making changes to a module repository as `make update` will overwrite your
|
|
commits, making `git reflog` the only way to recover them!
