Description

The shared library version changed from exiv2 0.11 to 0.12, going from 11 to 12. But the changelog doesn't show any withdrawn or changed functions. This means tha t if the library is updated, all programs that use it need to be recompiled, which is unnecessary if there is no ABI change.

Additional information:

poblano gdt 76 ~ > ls l /usr/pkg/lib/libexiv2*

poblano gdt 77 ~ > ufraw
Shared object "libexiv2-0.11.so" not found

(rebuilding ufraw fixes this, of course)

The interface did change: New (and modified) pretty-print functions result in an API change of the output operator for class Exifdatum, even the improved tag descriptions constitute a change of API. Applications potentially need to change. See this thread for a discussion and a real example how the GPS pretty-print functions broke digikam when they were first introduced in SVN:

I'm not an expert for this whole library versioning issue and I don't like the situation, suggestions are most welcome.

There was no more feedback, I'm closing this issue now.
