Description Simon 2016-03-14 17:47:04 UTC
I compiled digikam5 from git commit 1b9a889. Digikam shows errors on startup indicating that it did not find the digikamimageplugins (digikamimageplugin_transform, ...). These files are installed into lib/x86_64-linux-gnu/plugins/ while digikam searches for these files per default (no QT_PLUGIN_PATH set) in lib/x86_64-linux-gnu/qt5/plugins/. Adding the first path to the env variable QT_PLUGIN_PATH fixes this. Digikam should install these files into lib/x86_64-linux-gnu/qt5/plugins/.


Reproducible: Always

Steps to Reproduce:
1. compile and install digikam (debug)
2. run digikam, look at stdout/stderr

Actual Results:  
Imageplugins are not found:

Error loading plugin "digikamimageplugin_color" "The shared library was not found." 
Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
The environment variable QT_PLUGIN_PATH might be not correctly set
digikam.general: ImagePluginLoader: createInstance returned 0 for  "ImagePlugin_Colour"  ( "digikamimageplugin_color" )  with error:  "The shared library was not found."
Error loading plugin "digikamimageplugin_decorate" "The shared library was not found." 
Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
The environment variable QT_PLUGIN_PATH might be not correctly set
digikam.general: ImagePluginLoader: createInstance returned 0 for  "ImagePlugin_Decorate"  ( "digikamimageplugin_decorate" )  with error:  "The shared library was not found."
Error loading plugin "digikamimageplugin_enhance" "The shared library was not found." 
Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
The environment variable QT_PLUGIN_PATH might be not correctly set
digikam.general: ImagePluginLoader: createInstance returned 0 for  "ImagePlugin_Enhance"  ( "digikamimageplugin_enhance" )  with error:  "The shared library was not found."
Error loading plugin "digikamimageplugin_fxfilters" "The shared library was not found." 
Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
The environment variable QT_PLUGIN_PATH might be not correctly set
digikam.general: ImagePluginLoader: createInstance returned 0 for  "ImagePlugin_FxFilters"  ( "digikamimageplugin_fxfilters" )  with error:  "The shared library was not found."
Error loading plugin "digikamimageplugin_transform" "The shared library was not found." 
Plugin search paths are ("/usr/lib/x86_64-linux-gnu/qt5/plugins", "/usr/bin") 
The environment variable QT_PLUGIN_PATH might be not correctly set
digikam.general: ImagePluginLoader: createInstance returned 0 for  "ImagePlugin_Transform"  ( "digikamimageplugin_transform" )  with error:  "The shared library was not found."


Expected Results:  
Imageplugins found and loaded.

Digikam uses "qtpaths --plugin-dir" to find the plugin directory. Which directory is displayed with "qtpaths --plugin-dir"?

Maik
Comment 2 Simon 2016-03-14 19:12:29 UTC
This results in
qtpaths: could not find a Qt installation of ''

Comment 3 Maik Qualmann 2016-03-14 19:36:45 UTC
Then should "qtpaths --writable-path HomeLocation" also do not work? DigiKam uses QStandardPaths to find folders and datas. This has to work, otherwise digiKam will not work properly. I think something is wrong with your Qt installation.

Comment 4 Simon 2016-03-14 21:17:19 UTC
That gave the same result. You are right about the Qt installation. I 
only installed the packages that were necessary for cmake to run without 
errors. Therefore I was missing the qtpaths binary file for qt5, I only 
had a wrapper binary by qtchooser. Installing qttools5-dev-tools 
provides the necessary file and now the output is correct:

(stretch-digikam5)simon@simon-x220-deb:/usr$ qtpaths --plugin-dir
/usr/lib/x86_64-linux-gnu/qt5/plugins

I uninstalled, recompiled and installed digikam but the plugin files are 
stilled installed in lib/x86_64-linux-gnu/plugins/.

Comment 5 Maik Qualmann 2016-03-14 21:25:03 UTC
Do you have remove the build directory and run the bootstrap.linux script again?

Maik
Comment 6 Simon 2016-03-14 21:29:47 UTC
I did remove the build directory and then ran
cmake -DCMAKE_INSTALL_PREFIX=/usr/ -DBUILD_TESTING=OFF 
-DCMAKE_BUILD_TYPE=debug -DENABLE_INTERNALMYSQL=ON 
-DENABLE_MYSQLSUPPORT=ON -DENABLE_AKONADICONTACTSUPPORT=OFF ..
again, as there is no bootstrap script in the master branch (digikam5).

Comment 8 Simon 2016-03-14 23:30:11 UTC
This is embarrassing, sorry for wasting your time and thanks for your 
patience:
I used git://anongit.kde.org/digikam instead of using the 
software-compilation repo. Using the software-repo this problem 
disappears (and would have never come up in the first place).
This "bug" can be closed.

Comment 9 caulier.gilles 2016-08-13 21:37:01 UTC
Git commit fd9d85af744ed7895de1f3ef46790d5bf8424576 by Gilles Caulier.
Committed on 13/08/2016 at 17:29.
Pushed by cgilles into branch 'master'.

Final stage about editor tools.
Delete Image Editor Plugins interface. This will speedup initialization of digiKam and Showfoto,
and remove a run-time dependencies with plugin files to load/unload on memory, which is problem atic with non KDE desktop, MacOS and Windows.
