Packages in PPA doesn't generate correct shlibs

[Julien Lavergne]

When you upload a new library to the PPA, this new version number is not used when you build new package in this package.

Example :
In this PPA : https://edge.launchpad.net/~synapse-core/+archive/ppa/+packages?field.name_filter=&field.status_filter=published&field.series_filter=lucid
There is a new version of libzeitgeist (0.2.14, and the version in main Ubuntu repositories is 0.2.8.
When you rebuild a package, using ${shlibs:Depends} in debian/control, it should generate a depend libzeitgeist-1.0-0 (>= 0.2.14), but the depend generated is just libzeitgeist-1.0-0 (without the version).

Hi Julien,

Requirements for newer versions of a library in shlibs will only be added if that library's SONAME has been changed or if it is using symbol versioning and your package uses a symbol that was only recently introduced. As far as I can tell this is correct behaviour.

Cheers,

Jelmer

Hi Jelmer

No, the behavior is correct in the main Ubuntu repository, only the behavior on the PPA is incorrect.

If you build package foo with libbar1 (0.2), foo will depends on libbar1 (= 0.2) using ${shlibs:Depends}
If you build the same package foo with libbar1 (0.4) in your PPA (0.2 still available in Ubuntu), foo will depends on libbar1 without any version.
