Description Antonio Rojas 2014-10-19 16:57:15 UTC

In the Qt5 build, the plugin install dir seems to be hardcoded to $libdir/qt5/plugins. Plugins should be installed to the defult Qt plugin path of the system instead (qtpaths --plugin-dir, in my system it's /usr/lib/qt/plugins)

Reproducible: Always

Comment 1 Harald Sitter 2014-10-20 06:54:53 UTC

option(PHONON_INSTALL_QT_EXTENSIONS_INTO_SYSTEM_QT "Install Qt designer plugins, QML plugins and mkspecs into the system Qt install directory or not" FALSE)

Comment 2 Antonio Rojas 2014-10-20 07:09:27 UTC

The backends don't seem to honor that variable. phonon_gstreamer.so is still installed to /usr/lib/qt5/plugins

Comment 3 Harald Sitter 2014-10-20 07:19:43 UTC

That could be.
What'd be the point of not forcing it in there though? It also didn't do that with the qt4 build (always went to kde4 IIRC).

Comment 4 Antonio Rojas 2014-10-20 07:21:42 UTC

Mostly consistency, as it doesn't seem to break functionality. In my system phonon-gstreamer is the only package installing stuff to /usr/lib/qt5

Comment 5 Harald Sitter 2014-10-20 07:30:52 UTC

If you feel this is worthwhile, patches are always welcome :) FWIW I would suggest that the qt4/qt5 subdir should be dropped entirely and instead $LIBPREFIX/$PHONOSONAME/backends/ should be used as plugin lookup happens completely opaquely inside libphonon there is absolutely no reason why it would put the plugins in a global qt plugin directory.

Otherwise this probably will eventually go away with a transition to extra-cmake-modules, or well, maybe, or not...
Not worth fixing explicitly IMO as it only increases "neatness" rather than making things better.

Comment 6 Andrés Rodríguez 2016-10-15 15:53:03 UTC

Requesting reopening. This inconsistency is quite an annoying edge case when we have to probe for Qt libs using pkg-config, where we have to guess which qt folder contains what we're looking for adding unnecessary complexity because of two packages that may or may not exist in the user's system.
