FRR depends on the relatively new ``libyang`` library to provide YANG/NETCONF
|
||
|
|
support. Unfortunately, most distributions do not yet offer a ``libyang``
|
||
|
|
package from their repositories. Therefore we offer two options to install this
|
||
|
|
library.
|
||
|
|
|
||
|
|
**Option 1: Binary Install**
|
||
|
|
|
||
|
|
The FRR project builds some binary ``libyang`` packages.
|
||
|
|
|
||
|
|
RPM packages are at our `RPM repository <https://rpm.frrouting.org>`_.
|
||
|
|
|
||
|
|
DEB packages are available as CI artifacts `here
|
||
|
|
<https://ci1.netdef.org/browse/LIBYANG-LIBYANG21/latestSuccessful/artifact>`_.
|
||
|
|
|
||
|
|
.. warning::
|
||
|
|
|
||
|
|
``libyang`` version 2.1.128 or newer is required to build FRR.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
The ``libyang`` development packages need to be installed in addition to the
|
||
|
|
libyang core package in order to build FRR successfully. Make sure to
|
||
|
|
download and install those from the link above alongside the binary
|
||
|
|
packages.
|
||
|
|
|
||
|
|
Depending on your platform, you may also need to install the PCRE
|
||
|
|
development package. Typically this is ``libpcre2-dev`` or ``pcre2-devel``.
|
||
|
|
|
||
|
|
**Option 2: Source Install**
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
Ensure that the `libyang build requirements
|
||
|
|
<https://github.com/CESNET/libyang/#build-requirements>`_
|
||
|
|
are met before continuing. Usually this entails installing ``cmake`` and
|
||
|
|
``libpcre2-dev`` or ``pcre2-devel``.
