   1 The libyang library can be installed from third-party packages available `here
   2 <https://ci1.netdef.org/browse/LIBYANG-YANGRELEASE/latestSuccessful/artifact>`_.
   3
   4 Note: the libyang dev/devel packages need to be installed in addition
   5 to the libyang core package in order to build FRR successfully.
   6
   7 For example, for CentOS 7.x:
   8
   9 .. code-block:: shell
  10
  11    wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/CentOS-7-x86_64-Packages/libyang-0.16.46-0.x86_64.rpm
  12    wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/CentOS-7-x86_64-Packages/libyang-devel-0.16.46-0.x86_64.rpm
  13    sudo rpm -i libyang-0.16.46-0.x86_64.rpm libyang-devel-0.16.46-0.x86_64.rpm
  14
  15 or Ubuntu 18.04:
  16
  17 .. code-block:: shell
  18
  19    wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/Ubuntu-18.04-x86_64-Packages/libyang-dev_0.16.46_amd64.deb
  20    wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/Ubuntu-18.04-x86_64-Packages/libyang_0.16.46_amd64.deb
  21    sudo apt install libpcre3-dev
  22    sudo dpkg -i libyang-dev_0.16.46_amd64.deb libyang_0.16.46_amd64.deb
  23
  24 Alternatively, libyang can be built and installed manually by following
  25 the steps below:
  26
  27 .. code-block:: shell
  28
  29    git clone https://github.com/opensourcerouting/libyang
  30    cd libyang
  31    git checkout -b tmp origin/tmp
  32    mkdir build; cd build
  33    cmake -DENABLE_LYD_PRIV=ON ..
  34    make
  35    sudo make install
  36
  37 When building libyang on CentOS 6, it's also necessary to pass the
  38 ``-DENABLE_CACHE=OFF`` parameter to cmake.

  41 <https://github.com/CESNET/libyang/blob/master/README.md#build-requirements>`_
  42 first.
