Created attachment 6576 output.txt I tried to compile and install this plugin manually on my Sabayon Linux machine, by getting the tar.bz2 archive of the source code for version 1.4.7, extracting it and running `./configure --prefix=/usr && make && sudo make install`. At the make stage I received errors. To get a full log of these errors I ran `make > output.txt 2> errors.txt`, attached is output.txt. While here (http://paste2.org/IygmNbKw, it is 1.8 MB in size so I could not attach it) is my errors.txt file.
Responding to acknowledge I've received your bug - hope to look it over within a few days.
Firstly I apologise for the delay in getting to this - has taken some time to get out of holiday mode and into proper time management again... The error appears to be initially complaining about a used library rather than the plugin - I'm not familiar with how this problem is reported, so its either gtkmm-2.4, glibmm-2.4 or sigc++-2.0 that has upset the version of GCC that you're using - apparently someones presumably recently updated it to rely on C++11, and the version of GCC you're using is too old to cope (v5.3.1-5 on Debian Testing). Looking through glibmm's changelog (https://github.com/GNOME/glibmm/commits/master?page=1) theres quite a few mentions of C++11. Any reason why you're using an old version of GCC?
No feedback, so resolving as invalid (the compiler is probably too old).
