Can't load installed plugin in xfce4

[amxyz]

Hi,

I'm using a RPI4 and I installed some plugins which I downloaded from https://docs.xfce.org/xfce/xfce4-panel/start. The plugins were compiled correctly and placed in

Code: Select all

/usr/lib/xfce4/panel/plugins

these are the libs of the plugins:

Code: Select all

libpulseaudio-plugin.la  libpulseaudio-plugin.so  libweather.la  libweather.so

The .desktop-files were placed in this folder:

Code: Select all

/usr/share/xfce4/panel/plugins

The file weather.desktop looks like this:

Code: Select all

[Xfce Panel]
Type=X-XFCE-PanelPlugin
Name=Weather Update
Icon=xfce4-weather
X-XFCE-Internal=FALSE
X-XFCE-Module=weather
X-XFCE-API=2.0
X-XFCE-Exec=/usr/lib/xfce4/panel/plugins/

The file pulseaudio.desktop looks like this:

Code: Select all

[Xfce Panel]
Type=X-XFCE-PanelPlugin
Encoding=UTF-8
Name=PulseAudio Plugin
Icon=xfce4-pulseaudio-plugin
X-XFCE-Module=pulseaudio-plugin
X-XFCE-Internal=FALSE
X-XFCE-API=2.0
X-XFCE-Exec=/usr/lib/xfce4/panel/plugins/

When I rightclick on panel > Panel > Add new items neither the weather plugin nor the pulseaudio plugin appear there. How do I tell xfce4 that I have installed some plugins so that I can add them on the panel?

I just figured it out by myself. The external plugins are now loaded by the panel.

What was the cause of the error, and how did you fix it? Someone else may one day find this thread and benefit from your solution.

I found out that the libraries of the plugins are installed in:

/usr/lib/xfce4/panel/plugins/

Since I'm running gentoo on a 64 bit system I moved the libraries into the folder:

/usr/lib64/xfce4/panel/plugins/

I also had to edit one *.desktop-file so it looks like this now:

[Xfce Panel]
Type=X-XFCE-PanelPlugin
Name=Weather Update
Icon=xfce4-weather
X-XFCE-Internal=FALSE
X-XFCE-Module=weather
X-XFCE-API=2.0

API= 2.0 means that it is for gtk3 whereas API=1.0 is only for gtk2.

And then I restarted the panel by entering:

Code: Select all

> xfce4-panel -r

Then I was finally able to load the plugins.
