How to install termite

Over here is an install script, that nicely explains all dependencies and stuff, I'll just copy that for you ;)

Install dependencies

sudo apt install -y g++ libgtk-3-dev gtk-doc-tools gnutls-bin \
    valac intltool libpcre2-dev libglib3.0-cil-dev libgnutls28-dev \
    libgirepository1.0-dev libxml2-utils gperf build-essential

Get and install vte-ng

git clone https://github.com/thestinger/vte-ng.git
echo export LIBRARY_PATH="/usr/include/gtk-3.0:$LIBRARY_PATH"
cd vte-ng && ./autogen.sh && make && sudo make install
cd ..

Get and install termite, and setup

git clone --recursive https://github.com/thestinger/termite.git
cd termite && make && sudo make install
sudo ldconfig
sudo mkdir -p /lib/terminfo/x
sudo ln -s /usr/local/share/terminfo/x/xterm-termite /lib/terminfo/x/xterm-termite

Voila, this should be it ....

I think the simplest way to install is the following:

cd /tmp
wget https://raw.githubusercontent.com/Corwind/termite-install/master/termite-install.sh
chmod +x ./termite-install.sh
./termite-install.sh

Now update your default terminal emulator:

sudo update-alternatives --config x-terminal-emulator

Have a good day!
