owncloud-client-1.6.0 build log
Patch allows to build with qt4 if qt5 is installed on the system.

Description Jérôme Borme 2014-06-08 11:14:31 UTC
If qt5 is installed, net-misc/owncloud-client depends on dev-qt/qtprintsupport, dev-qt/linguist-tools, dev-libs/qtkeychain[qt5]

If qt5 (-core, -gui) is installed, then the build script will use it instead of qt 4.8. If then in this situation, owncloud depends on dev-qt/qtprintsupport (qt overlay), dev-qt/linguist-tools (qt overlay), dev-libs/qtkeychain (main tree).

Typical message in the configure step is:

CMake Error at cmake/modules/QtVersionAbstraction.cmake:19 (find_package):
  By not providing "FindQt5PrintSupport.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "Qt5PrintSupport", but CMake did not find one.

  Could not find a package configuration file provided by "Qt5PrintSupport"
  with any of the following names:


I can't say for more, on my system qtkeychain won't compile with qt5, although from the ebuild it seems it should.

Reproducible: Always

1) Please post your `emerge --info' output in a comment.
2) Please attach the entire build log to this bug report

owncloud-client-1.6.0 build log

Note that this bug report has several related issues:

1. There should be a USE flag in owncloud-client for qt5 and qt4.
2. In case of USE=qt5, the ebuild should depend on dev-qt/qtprintsupport, dev-qt/linguist-tools, dev-libs/qtkeychain[qt5] (perhaps more)
3. And finally, as it happens, owncloud-client-1.6.0 does not build even when qtkeychain is installed.

Regarding the last point, it seems that dev-libs/qtkeychain-0.3.0 refuses to build with qt5 support, and this could be why owncloud-client then does not find the lib.

Here is what happens when I try to force qtkeychain to build with qt5:

# USE="-qt4 qt5" emerge --ask qtkeychain

These are the packages that would be merged, in order:

Calculating dependencies |

!!! Problem resolving dependencies for dev-libs/qtkeychain                    ... done!

!!! The ebuild selected to satisfy "qtkeychain" has unmet requirements.
- dev-libs/qtkeychain-0.3.0::gentoo USE="-qt4 (-qt5)"

  The following REQUIRED_USE flag constraints are unsatisfied:
    any-of ( qt4 qt5 )
Comment 5 Jouni Kosonen 2014-06-08 14:49:28 UTC
(In reply to Jérôme Borme from comment #4)
dev-libs/qtkeychain allows building for *both* qt4 and qt5, it's just that the qt5 use flag is currently masked in profiles/base/use.mask .

These were enough to get owncloud-client compile and install here:

/etc/portage/profile/package.use.mask/qt5: dev-libs/qtkeychain -qt5
/etc/portage/package.use/qt5: dev-libs/qtkeychain qt4 qt5

It compiles here but complains that system tray is required.

Yes same error here. After uninstalling qt5 and emerging again owncloud-client-1.6.0, it launches and finds the system tray just as previous versions did. (My system tray is from fluxbox.)
Comment 9 Michael Hampicke 2014-06-12 16:24:39 UTC
Having the same problem here (systray missing). Is it possible to have qt4 and qt5 installed in slots and compile owncloud-client against qt4?

Someone needs to spend time working on the ebuild to make this possible, but as a temporary workaround I uninstalled qt5 to compile owncloud-client, then installed qt5 again from binary packages I prepared in advance. Instructions:

export LIST="=qtdbus-5.3.0 =qtnetwork-5.3.0 =qtopengl-5.3.0 =qtdeclarative-5.3.0 =qtprintsupport-5.3.0 =qtkeychain-0.3.0 =qtwebkit-5.3.0 =qtcore-5.3.0 =qtgui-5.3.0 =qtsvg-5.3.0 =qtwidgets-5.3.0 =qtxmlpatterns-5.3.0 =qtsql-5.3.0 =qtscript-5.3.0 =qttest-5.3.0 =qtxml-5.3.0 =linguist-tools-5.3.0"
quickpkg $LIST
emerge --unmerge $LIST
emerge =net-misc/owncloud-client-1.6.0
emerge --getbinpkgonly $LIST

I expected some trouble with qtkeychain as in this procedure, owncloud-client is linked with qtkeychain compiled only with qt4, and in the end qtkeychain is overwritten with a version compiled prepared for both qt4 and qt5. But I had no problem.

You can force a Qt 4 build with -DBUILD_WITH_QT4=ON.

also seems to be requiered

Patch allows to build with qt4 if qt5 is installed on the system.

I have taken the information from the previous comments to update the ebuild.

USE flags qt4 and qt5 are now available, which will depend on the corresponding SLOTs. I have included the mentioned additional packages.

qt5 will be ignored, if the qt4 USE flag is enabled.

Caution: I have *not tested to install* the ebuild with qt5 USE flag enabled. I have only tested, if emerge could resolve the dependencies. Therefore, it is probable, that it won't work.
Comment 14 Thomas Capricelli 2014-06-23 22:43:39 UTC
got hit by a similar problem today with portage updated few hours ago. I dont need/want owncloud to be built against qt5, i dont really care as far as it works.

net-misc/owncloud-client-1.6.0 fails with :

Comment 15 Bernard Cafarelli gentoo-dev 2014-06-26 15:42:04 UTC
Thanks for the report and suggestions, I'll get this fixed before bumping to 1.6.1 (though the qt5 parts will be untested as I do not have it installed)
Comment 16 Bernard Cafarelli gentoo-dev 2014-06-27 14:55:35 UTC
All suggestions (and a few additional changes) merged in 1.6.1 ebuild, thanks everybody!
Comment 17 Thomas Capricelli 2014-06-27 20:28:48 UTC
tested today. Works with USE="qt4 -qt5". Thanks!

As a side note, with "qt4 qt5", there's no error, though i haven't been until the end of compilation. Usually there's a rule "only one of" in the ebuild.

I tested all cases:
* USE="-qt4 -qt5" -> not possible to resolve dependencies
* USE="-qt4 qt5" -> links with qt5 (and executable complains of lack of of system tray)
* USE="qt4 -qt5" -> links with qt4 and runs normally
* USE="qt4 qt5" -> also links with qt4 and runs normally
Comment 19 Bernard Cafarelli gentoo-dev 2014-06-30 21:19:25 UTC
Thanks for the tests, I updated the REQUIRED_USE line to require qt4 or qt5, but not both (as other applications currently do)
