Automatic update for pdf with Kile

The latest stable version of Kile (2.1.3) does not offer automatic updates. You can however update to the development version (Kile 3 beta 1) to get automatic updates and live preview.

The dev version is in beta from quite some time and I use it in my production environment without issues. It is still a beta by the way, so there may be some rough edges.

To install the beta version of Kile in ubuntu you need to add this PPA:

sudo add-apt-repository ppa:kile/livepreview
sudo apt-get update
sudo apt-get install kile

As the PPA dev says, if you're updgrading from Kile 2.1.3 then

it is recommended to reset the configuration of the tools. In order to do so, open the tool configuration section in the configuration dialog, which can be found under Settings / Configure Kile... / Tools / Build, and press the "Restore Default Tools..."

For other Linux distros, the generic instructions to build Kile from source are:

git clone --depth 1 git://anongit.kde.org/kile
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
make
sudo make install

You need the build tools provided by your distro, see the distro documentation to check how to install them.

After you got the beta version, to enable automatic updates go to

Settings -> 
Configure Kile -> 
Live Preview -> 
Compile documents whenever there are changes after <insert milliseconds>
