<br>
so liborcus now build-depends on libixion due to an update that was synced to<br>
utopic. I cleared most of the work needed for a MIR[1], but will not yet add a<br>
symbols file, as a quick check shows it would include (non-template) symbols from<br>
the ::std:: and ::boost:: namespaces which clearly it shouldnt. So as per<br>
<a href="https://wiki.debian.org/UsingSymbolsFiles" target="_blank">https://wiki.debian.org/UsingSymbolsFiles</a>: "If you find (on some arches)<br>
symbols that are exported which are not supposed to be public, you must not use<br>
symbols versioning at all." Before shipping a symbols file, upstream would need<br>
to get its ducks in a row.<br>
<br>
Note in addition, that:<br>
- currently the only possible client of libixion is LibreOffice<br>
- the libixion ABI so far does not have any ambition to be stable yet -- in<br>
fact, IIRC the ABI changed with every release so far<br>
- even LibreOffice on utopic isnt currently using the package, but a bundled<br>
version of libixion/liborcus anyway (actually it cant be otherwise, as<br>
LibreOffice is in main)<br>
<br>
So for now, Id suggest to either:<br>
a/ keep LibreOffice on its internal build versions of libixion/liborcus and<br>
not update the packages in the archive (which are unused anyway)<br>
b/ update libixion/liborcus without a symbols file for now, use that from<br>
LibreOffice and be optimistically confident that upstream libixion will fix<br>
their exports by the time there are actually other clients than LibreOffice for<br>
the lib (if that should ever happen).<br>
