'build for Ubuntu 18.04 (bionic)' + +Between building packages for specific distributions, the only difference +in the package itself lies in the automatically generated shared library +dependencies, e.g. libjson-c2 or libjson-c3. This means that the +architecture independent packages should **not** have a suffix appended. +Also, the current Debian testing/unstable releases should not have any suffix +appended. + +For example, at the end of 2018 (i.e. ``buster``/Debian 10 is the current +"testing" release), the following is a complete list of `.deb` files for +Debian 8, 9 and 10 packages for FRR 6.0.1-1 with RPKI support:: + + frr_6.0.1-1_amd64.deb + frr_6.0.1-1~deb8u1_amd64.deb + frr_6.0.1-1~deb9u1_amd64.deb + frr-dbg_6.0.1-1_amd64.deb + frr-dbg_6.0.1-1~deb8u1_amd64.deb + frr-dbg_6.0.1-1~deb9u1_amd64.deb + frr-rpki-rtrlib_6.0.1-1_amd64.deb + frr-rpki-rtrlib_6.0.1-1~deb8u1_amd64.deb + frr-rpki-rtrlib_6.0.1-1~deb9u1_amd64.deb + frr-doc_6.0.1-1_all.deb + frr-pythontools_6.0.1-1_all.deb + +Note that there are no extra versions of the `frr-doc` and `frr-pythontools` +packages (because they are for architecture ``all``, not ``amd64``), and the +version for Debian 10 does **not** have a ``~deb10u1`` suffix. + +.. warning:: + + Do not use the ``-`` character in the version suffix. The last ``-`` in + the version number is the separator between upstream version and Debian + version. ``6.0.1-1~foobar-2`` means upstream version ``6.0.1-1~foobar``, + Debian version ``2``. This is not what you want. + + The only allowed characters in the Debian version are ``0-9 A-Z a-z + . ~`` + +.. note:: + + The separating character for the suffix **must** be the tilde (``~``) + because the tilde is ordered in version-comparison before the empty + string. That means the order of the above packages is the following: + + ``6.0.1-1`` newer than ``6.0.1-1~deb9u1`` newer than ``6.0.1-1~deb8u1`` + + If you use another character (e.g. ``+``), the untagged version will be + regarded as the "oldest"! |
