Subject: plasma-nm: error loading QML file applet to undefined symbol in libplasmanm_editor.so

Date: Tue, 17 May 2016 09:38:09 +0200

Package: plasma-nm
Version: 4:5.5.4-1
Severity: normal

Dear Maxy, dear Maintainer,

as a reminder of something to take care of before transitioning experimental
Plasma/KF5/Qt packages to Sid:

plasma-nm qml applet shows

error while loading QML file:

file:///usr/share/plasma/plasmoids/org.kde.plasma.networkmanagement/contents/ui/main.qml:23:1:

plugin cannot be loaded for module "org.kde.plasma.networkmanagement":

The library

/usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/networkmanagement/libplasmanm_qmlplugins.so

cannot be loaded:

/usr/lib/x86_64-linux-gnu/libplasmanm_editor.so: undefined symbol:

_ZN14NetworkManager11WimaxDevice16staticMetaObjectE


There is a similar bug reported with Ubuntu:

Plasma Network Manager crashes 
https://bugs.launchpad.net/ubuntu/+source/plasma-nm/+bug/1581371


The following bug report also mentions it starting from comment 36:

[Kubuntu] Fail to connect to wifi after a recent update 
https://bugs.launchpad.net/ubuntu/+source/networkmanager-qt/+bug/1569674

Comment 38 mentions as a workaround to downgrade libkf5networkmanagerqt6.

https://bugs.launchpad.net/ubuntu/+source/networkmanager-qt/+bug/1569674/comments/39


At the time this bug report happened I had 5.21.0-1 from experimental
installed. apt install libkf5networkmanagerqt6=5.16.0-1 indeed brings back
the qml applet.

Maybe plasma-nm needs upgrading for it to work with the library from KF 5.21?

Thanks,
Martin

Ups, I thought the Wimax symbols appeared and disappeard only in the 
experimental version, I was clearly wrong. Ok, I'm adding a Breaks: plasma-nm 
(<= 4:5.6~) in libkf5networkmanagerqt6 and bumping the build dependencies in 
plasma-nm.

Thanks for the report!

Happy hacking,

Subject: Broken ABI in networkmanager-qt

Hi,

we decided to drop WiMAX support in nm-qt when it's compiled against NM 1.2.0, 
but this seems to break binary compatibility when nm-qt was previously build 
against older NM version. I didn't realize this before that this could happen 
and now I'm not sure how fix that.

We could either:
1) Revert the change removing WiMAX support, but that would break ABI 
compatibility one more time.

2) Keep it as it is and let packagers know about this problem and ask them to 
rebuild everything using nm-qt (plasma-nm, plasma-workspace) in case they 
already have NM 1.2.0.

What do you think is a better option?

I'm really sorry for this problem and will be more careful next time when 
doing such changes. Thanks.

Regards,
Jan
