Embedded Linux library
======================
In order to compile the daemon and utilities the development version of
Embedded Linux library is required to be present. The development
repositories can be found here:
git://git.kernel.org/pub/scm/libs/ell/ell.git
https://kernel.googlesource.com/pub/scm/libs/ell/ell.git
The build systems requires that the Embedded Linux library source code
is available on the same top level directory as the source code:
.
|--- ell
| |--- ell
| `--- unit
`--- ofono
|--- src
`--- tools
It is not required to build or install Embedded Linux library. The build
will happen when building the Wireless daemon and it will then be linked
internally.
When using --enable-external-ell build option, it is not required that the
Embedded Linux library source code is available in the top level directory.
Kernel Dependencies
===================
In order to have the PPP stack working in oFono you need to enable CONFIG_TUN
(Universal TUN/TAP device driver support) in your kernel .config.
