libkdcraw and KDE 4.1.x

hi everyone =)

in the 4.1 branch, a set of changes was made to libkdcraw which consisted of a
substantial rewrite of the library that caused a change in ABI and a change in
the .so name.

i assume this change was made in the 4.1 branch because people are developing
against the 4.1 branch of kdegraphics.

unfortunately, such changes in ABI and features aren't allowed in the stable
branch after it's initial ".0" release.

these change are fine, indeed welcome, in trunk/, but the changes will need to
be reverted in the 4.1 branch.

we can always require the new version of the library for specific applications,
and we (kdegraphics people) coul even do a release of the new library before
4.2 happens.

before i just went off reverting things, however, i felt it was proper to first
discuss it here (and hopefully the committer of those changes can revert it
from the 4.1 branch themselves). 4.1.2 is due to be released shortly, so
taking care of this in a timely fashion is important..

thanks for your time ...

Aaron.

Nothing have been re-written in KDE 4.1 branch. this version is always based on dcraw/QProcess

Libkdcraw based on LibRaw, which is the re-writting of library is done in trunk and only in trunk.

Best

Are you sure of that? I mean we cannot build digikam using libkdcraw from kde
4.1.1 branch, iirc you said you've backported something into kde 4.1.2 branch.
Am I wrong?

Are you sure of that?

yes, i'm sure :

4.1 branch: http://websvn.kde.org/branches/KDE/4.1/kdegraphics/libs/libkdcraw/

trunk : http://websvn.kde.org/trunk/KDE/kdegraphics/libs/libkdcraw/

I'm always work on trunk with libraw port

4.1.1 branch, iirc you said you've backported something into kde 4.1.2 branch.
Am I wrong?

Excepted DNGConverter kipi-plugin, digiKam and all other plugins from trunk must compile fine using libkdcraw KDE 4.1 branch version. there are #ifdef in digiKam and kipi-plugins code to still compatible with both version. If not, please let's me hear which error you have with compiler.

For DNGConverter, i will disable the plugin if libkdcraw from KDE 4.1 branch is used. still in my TODO list
