libbb10styleplugin.so "file does not exist" error

[panmarco83]

I thought this was something hard coded that was causing this error but there is no reference to 'libbb10styleplugin' in your code anywhere..

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake:27 (message):
  The imported target "Qt5::Widgets" references the file

     "/usr/lib/x86_64-linux-gnu/qt5/plugins/styles/libbb10styleplugin.so"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

I've been trying to figure out where it comes from but I can't find said module on my system or in apt.
these are the ones I do have in the same folder that cmake is looking into:

adwaita.so
libkvantum.so
libqcleanlooksstyle.so
libqgtk2style.so
libqmotifstyle.so
libqplastiquestyle.so
libqt5ct-style.so

Seems like your Qt5::Widgets package may be broken. Have you tried repairing/reinstalling Qt?

[panmarco83]

Yes, to no avail.
Another thing is that libbb10styleplugin.so is a Black Berry 10 theme.
Qt needs to be compiled with BB10 support for this to be included.

Are you on Arch or Gentoo by any chance ?

[Maldela]

I'm on Arch. Is Qt5::Widgets different on Arch and Gentoo than on Ubuntu?

[panmarco83]

Don't know, but they are quite possibly compiled with different options I suppose.

[Maldela]

I don't really know how to help you here. Maybe ask on the Ubuntu forums?
My last attempt at fixing this would be editing /usr/lib/x86_64-linux-gnu/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake and deleting the part that references libbb10styleplugin.so.

[panmarco83]

There is no mention of it:

source@megumi:~$ cat /usr/lib/x86_64-linux-gnu/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake|grep -i libbb10styleplugin
source@megumi:~$ 

[Maldela]

But your original error message says /usr/lib/x86_64-linux-gnu/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake references /usr/lib/x86_64-linux-gnu/qt5/plugins/styles/libbb10styleplugin.so on line 27.

[panmarco83]

Interesting, I moved /usr/lib/x86_64-linux-gnu/cmake/Qt5Widgets/Qt5Widgets_QBB10StylePlugin.cmake away and tried to run cmake again, now it works..
My apologies, I had fixated on this being something on your end.
What I can tell is that the file might be an errant file from some package I have not figured out the origins of.
At the very least you might be able to use this issue as a possible solution if others bump into the same problem.
