How to build this software. It was tested on Mint 18.x and 19 versions, but will probably build just the same on the various *ubuntu systems too.
build-essential git valac libgee-0.8-dev libgtk-3-dev libjson-glib-dev gettext libgettextpo-dev
p7zip-full imagemagick
apt install build-essential git valac libgee-0.8-dev libgtk-3-dev libjson-glib-dev gettext libgettextpo-dev p7zip-full imagemagick
the following command will create a subdirectory from whatever directory you are currently in called conky-manager2 then download the files from github and put them in that subdirectory:
git clone https://github.com/zcot/conky-manager2.git
cd conky-manager2
make
( follow instructions here to build a .deb
file instead: https://gist.github.com/zcot/ff43f40ceaf970623bfd18ead1bd65b2 )
sudo make install
sudo make uninstall
