Version 0.16.74 or<o:p></o:p></p><p class=MsoNormal>newer (e.g. 0.16-r3 which is 0.16.105) is strongly recommended. Older<o:p></o:p></p><p class=MsoNormal>versions will create additional hazards at both build and runtime because<o:p></o:p></p><p class=MsoNormal>an extension module needs to be installed. Support for libyang versions<o:p></o:p></p><p class=MsoNormal>before 0.16.74 will be removed in the next non-stable FRRouting version.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>when using libyang before 0.16.74, make sure to specify the<o:p></o:p></p><p class=MsoNormal>--with-libyang-pluginsdir=/usr/lib/frr/libyang_plugins option (change<o:p></o:p></p><p class=MsoNormal>path to fit system)<o:p></o:p></p><p class=MsoNormal>Debian packaging has been completely overhauled (matches the changes in<o:p></o:p></p><p class=MsoNormal>6.0.2.)

This is the only supported way of doing any static linking<o:p></o:p></p><p class=MsoNormal>of FRR. (--disable-shared is NOT supported.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>all daemons now properly complete their startup before allowing their parent<o:p></o:p></p><p class=MsoNormal>to exit when the -d daemonization option is used.
