[Bug 311812] New: kipi plugins not loading, SO version mismatch

[Andreas K. Huettel]

https://bugs.kde.org/show_bug.cgi?id=311812

            Bug ID: 311812
          Severity: normal
           Version: 3.0.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: kipi plugins not loading, SO version mismatch
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Other
            Status: UNCONFIRMED
         Component: libkipi
           Product: digikam

Not sure which package this belongs to... This is Gentoo (yeah, sorry), with
kde-4.10beta2 combined with digikam-3.0.0beta3. All modules that are part of
kde proper are taken from kde, the rest from the digikam tarball. So,
libkipi-4.9.90 and kipi-plugins-3.0.0beta3.

Digikam-3.0.0beta3 refuses to load the plugins, outputting the following
messages:
igikam(14616)/KIPI (loading) KIPI::PluginLoader::init: Plugin
"Rajce.net-Export" has a SO version ( 0 ) which is different than libkipi ABI
version ( 10 ).  Refusing to load.
digikam(14616)/KIPI (loading) KIPI::PluginLoader::init: Plugin  "Erweiterte
Diaschau" has a SO version ( 0 ) which is different than libkipi ABI version (
10 ).  Refusing to load.
...

Any hints how to get around this?

You need to use libkipi from KDE 4.10 only.

Sound like you have an old version version of libkipi at the same time on your
computer. ABI and API are not compatible. you need to uninstall old one
before...

That's what I do (4.9.90 to be precise, and the libkipi tarball is except for
one .desktop file identical to the libkipi subdir of
digikam-3.0.0-beta3/extras). Besides, things build fine (which would not happen
with 4.9, I know.)

No obvious duplicates, and re-building and installing libkipi does not change
anything...

huettel@pinacolada /usr $ find /usr -name libkipi.so*
/usr/lib64/libkipi.so.10
/usr/lib64/libkipi.so

-rwxr-xr-x 1 root root 406240 18. Nov 20:51 /usr/lib64/libkipiplugins.so.3.0.0

Tracking this down... the comparison is in libkipi/pluginloader.cpp line 321.
"10" as SO version for libkipi actually looks good to me (correct me if I'm
wrong). The problem then is the "0" for the kipi-plugins. This is loaded from
the desktop files in  libkipi/pluginloader.cpp line 307...

What happens if the service .desktop files are not found? Could this result in
binVersion==0?

(I think the kipiplugin_gpssync.desktop etc files are not installed here, I'm
still trying to figure out why.)

Correction, they are installed, but ...

Found it.

Since we're in Gentoo building kipi-plugins in that subdirectory
extras/kipi-plugins alone, the global copy of FindKipi.cmake is used
(/usr/share/apps/cmake/modules/FindKipi.cmake). That copy comes from
kdelibs-4.9.90, and it seems that it is older than the local one in the digikam
tarball (the copyright date is from 2008 and it does not define
KIPI_SO_VERSION).

May I suggest you try to get the updated cmake file(s?) into kdelibs before
4.10 gets out? :)

Thanks in advance!

--- Comment #5 from Andreas K. Huettel <[hidden email]> ---
OK I can confirm
* after adding an updated FindKipi.cmake to the kdelibs files,
* and rebuilding kipi-plugins,
all is fine.

BTW, kdelibs(-4.9.90) also installs old versions of FindKdcraw.cmake and
FindKexiv2.cmake.  Right now this only seems to lead to warnings, but breakage
is possible.
