Selecting the right version
|
|
---------------------------
|
|
|
|
The versions of gluon are managed with tags and branches. Every tag is a stable release (like v2014.2 or v2014.3.1), every branch is a development branch, where 2014.3.x is a branch for 2014.3 bugfix releases and master is the unstable branch for the upcoming release. Branches should be used for development purposes, while tags can be used for productive releases. To check out a branch do:
|
|
|
|
::
|
|
|
|
git clone https://github.com/freifunk-gluon/gluon.git gluon
|
|
cd gluon
|
|
git checkout v2014.3
|
|
|
|
Please keep in mind that you need the appropriate site configuration for that gluon version.
|
|
|
|
Building the image
|
|
------------------
|
|
|
|
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`. Of these, the factory
|
|
images are to be used when flashing from the original firmware a device came with,
|
|
and sysupgrade is to upgrade from other versions of Gluon or any other OpenWRT-based
|
|
system.
|
|
|
|
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 two levels of `make clean`:
|
|
|
|
::
|
|
|
|
make clean
|
|
|
|
will ensure all packages are rebuilt; this is what you normally want to do after an update.
|
|
|
|
::
|
|
|
|
make dirclean
|
|
|
|
will clean the entire tree, so the toolchain will be rebuilt as well, which is
|
|
not necessary in most cases, and will take a while.
|
|
|
|
|
|
Environment variables
|
|
---------------------
|
|
|
|
Gluon's build process can be controlled by various environment variables.
|
|
|
|
GLUON_SITEDIR
|
|
Path to the site configuration. Defaults to ``site/``.
|
|
|
|
GLUON_IMAGEDIR
|
|
Path where images will be stored. Defaults to ``images/``.
|
|
|
|
GLUON_BUILDDIR
|
|
Working directory during build. Defaults to ``build/``.
|
|
|
|
|
|
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 clean
|
|
make
|
