Looking Glass Client
This guide will step you through building the looking glass client on Debian based systems from source, before you attempt to do this you should have a basic understanding how to use the shell.
Building the Application
Debian (and maybe Ubuntu)
apt-get install binutils-dev cmake fonts-freefont-ttf libsdl2-dev libsdl2-ttf-dev libspice-protocol-dev libfontconfig1-dev libx11-dev nettle-dev
yum install make cmake binutils-devel SDL2-devel SDL2_ttf-devel nettle-devel spice-protocol fontconfig-devel libX11-devel egl-wayland-devel wayland-devel mesa-libGLU-devel mesa-libGLES-devel mesa-libGL-devel mesa-libEGL-devel
OpenSuSE Leap 15.0+
zypper install make cmake binutils-devel libSDL2-devel libSDL2_ttf-devel libnettle-devel nettle spice-protocol-devel fontconfig-devel libX11-devel libconfig-devel libwayland-egl-devel
Either visit the site at Looking Glass Download Page
Or pull the lastest using the git command.
git clone https://github.com/gnif/LookingGlass.git
If you downloaded the file via the web link then you should have a 'zip' file. Simply unzip and cd into the new directory. If you used 'git' then cd into the 'LookingGlass' directory.
Should this all go well you should be left with the file looking-glass-client. Before you run the client you will first need to configure either Libvirt or Qemu (whichever you prefer) and then setup the Windows side service.
