Hello!

A quick progress report on my KDE efforts, without much progress, actually.
In the meantime, I got kdelibs compiled; some of the tests fail. But the
"hello world" program of some tutorial I found on the web compiles and runs.
I also compiled a "real" KDE application, ktouch. Now when one wants to run
it, one needs kde-runtime with (at least) lots of qml resources. I think there
would be quite some work, and maybe we would need to define some new search
paths, for Qt and/or KDE. For instance, the configure of Phonon complains
about the following:
-- PHONON_QT_IMPORTS_DIR is set to /gnu/store/50kyr9zs06cvp7ra22zs68zb05gq2xcf-phonon-4.8.3/lib64/qt
4/imports.
      The QML plugins for Phonon will not be installed into the Qt system installation directory,
      which is /gnu/store/lc0dijbmvl6a14zqi924azqrdsx34vwl-qt-4.8.6/imports .
      This means the QML plugins file will not be found by default.
      You can:
       * switch the cmake option PHONON_INSTALL_QT_EXTENSIONS_INTO_SYSTEM_QT to TRUE
       * set PHONON_QT_IMPORTS_INSTALL_DIR manually to the system Qt location
       * at runtime, set the QML_IMPORT_PATH environment variable
-- PHONON_QT_MKSPECS_INSTALL_DIR is set to /gnu/store/50kyr9zs06cvp7ra22zs68zb05gq2xcf-phonon-4.8.3/
share/qt4/mkspecs/modules.
      The Qt mkspecs file for Phonon will not be installed into the Qt system installation directory
,
      which is /gnu/store/lc0dijbmvl6a14zqi924azqrdsx34vwl-qt-4.8.6/mkspecs/modules .
      This means the qt_phonon.pri file will not be found by default.
      You can:
       * switch the cmake option PHONON_INSTALL_QT_EXTENSIONS_INTO_SYSTEM_QT to TRUE
       * set PHONON_QT_MKSPECS_INSTALL_DIR manually to the system Qt location
       * at runtime, with Qt >= 4.8, set the QMAKEPATH environment variable
-- PHONON_QT_PLUGIN_INSTALL_DIR is set to /gnu/store/50kyr9zs06cvp7ra22zs68zb05gq2xcf-phonon-4.8.3/lib64/qt4/plugins/designer.
      The Qt designer plugins for Phonon will not be installed into the Qt system installation directory,
      which is /gnu/store/lc0dijbmvl6a14zqi924azqrdsx34vwl-qt-4.8.6/plugins/designer .
      This means the designer plugins file will not be found by default.
      You can:
       * switch the cmake option PHONON_INSTALL_QT_EXTENSIONS_INTO_SYSTEM_QT to TRUE
       * set PHONON_QT_PLUGINS_INSTALL_DIR manually to the system Qt location
       * at runtime, set the QT_PLUGIN_PATH environment variable

Right now, I feel it does not make much sense to invest an arbitrary amount
of time here. Instead, I will start looking at kde-5 (without much urgency;
there is no reason to believe it will be easier, but the time will probably
be better spent).

This looks like three variables that could be handled with search path
specifications on the Qt package, no?

Thanks for the progress report!

Yes, that is why I wrote to the list, just in case someone else notices
similar needs in a package depending on Qt. I just read that the support for
Qt 4 will end in 2015. So I think we should concentrate on Qt 5 and KDE 5,
but I suppose that such mechanisms with the need for search path
specifications will be similar.
