Comment 46 for bug 1244629

Never mind. The latest version in git does indeed work. met.no changed their API from 1.1 to 1.2:

http://api.yr.no/weatherapi/locationforecastlts/1.2/documentation

1.2 was implemented in git in xfce4-weather-plugin this summer, and met.no deprecated 1.1 about a week ago. My problem was that I wasn't installing the git version properly. The panel in xubuntu uses /usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/ as the plugin path, but autogen.sh only allows you to set the first part of the prefix:

autogen.sh --prefix=/usr

But that installs to /usr/lib/xfce4/panel/plugins/, which is missing the x86_64-linux-gnu part of the path. So, I manually copied the libweather.so and libweather.la files to /usr/lib/x86_64-linux-gnu/xfce4/panel/plugins, restarted the panel with xfce4-panel -r, and that did it.
