Bug #499

shared library version changed apparently without an interface change

Added by Greg Troxel almost 15 years ago. Updated almost 13 years ago.

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 But the changelog doesn't show any withdrawn or changed functions.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*

lrwxr-xr-x 1 root wheel 16 Nov 28 20:33 /usr/pkg/lib/ ->
poblano gdt 77 ~ > ufraw
Shared object "" 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.
