h1. Installing Wt on Ubuntu

• Table of contents
• general features
• more database backends
• graphics, pdf, font, server-side OpenGL, ...
• used by some examples
• for building documentation
• cmake options:
• if cmake complains about not finding boost_random, add -DWT_NO_BOOST_RANDOM=ON
• if you installed graphicsmagick, add -DWT_WRASTERIMAGE_IMPLEMENTATION=GraphicsMagick

For installation of Wt on Ubuntu, you have the choice between the official package available in Ubuntu, prebuilt packages by Pau Garcia i Quiles (always updated to the newest Wt version) or installation from source.

h2. Installing from the Official Package

Since Ubuntu Intrepid (8.10), official packages for Ubuntu are available. To install Wt, run:

$ sudo aptitude install witty witty-dbg witty-dev witty-doc

This will automatically install all the required dependencies. If you only want the runtime library, you only need to install the witty package. The witty-dbg package contains the debug versions of the libraries. Make sure you install witty-dev (or libwtwhatever-dev) if you want to develop Wt applications.

The official package is usually a bit outdated due to the stabilization periods Debian and Ubuntu need prior to release. If you want to use the newest version of Wt and not build from source, read on.

h2. Installing from Prebuilt Packages

Since Wt 2.0.3, unofficial packages for Ubuntu are being built by "Pau Garcia i Quiles":http://www.elpauer.org/. To install Wt, add the "Wt PPA":http://launchpad.net/~pgquiles/+archive/wt to your repositories (check "Adding this PPA to your system" in the Wt PPA page). After adding the repository to your system, run:

$ sudo apt-get update
$ sudo aptitude install libwt*

This will automatically install all the required dependencies. If you only want the runtime library, you only need to install the libwt24, libwthttp24, libwtext24, etc packages (no -dev, -doc or -dbg packages). The libwt-dbg package contains the debug versions of the libraries.

These packages are built by the maintainer of the official Debian and Ubuntu packages and are always updated to the latest version of Wt. If you want to use the newest version of Wt and not build from source, this is the preferred method.

Please note in the past packages were named witty, witty-dev, witty-doc and witty-dbg. These package still exist but only as transitional packages and will be removed in the future. It is recommended that you install libwt*.

h2. Installing from Sources

h3. Installing System Dependencies

Minimal dependencies:

sudo apt-get install gcc g++ libboost-all-dev cmake make

Optional dependencies (this list changes sometimes):

general features¶

sudo apt-get install libssl-dev libfcgi-dev

more database backends¶

sudo apt-get install libpq-dev libmysqlclient-dev firebird-dev

graphics, pdf, font, server-side OpenGL, ...¶

sudo apt-get install libpng12-dev libgraphicsmagick1-dev libhpdf-dev libpng12-dev libpango1.0-dev mesa-common-dev

used by some examples¶

sudo apt-get install asciidoc libqt4-dev

for building documentation¶

sudo apt-get install doxygen graphviz

If an optional dependency is not found, you can still compile and use Wt. Some features may not be available in that Wt (e.g. no pdf rendering, or no server-side 2D image rendering, ...)

h3. Get Wt

Go to http://www.webtoolkit.eu/wt/download or download using wget:

wget -c http://kent.dl.sourceforge.net/sourceforge/witty/wt-x.y.z.tar.gz
tar xvxf wt-x.y.z.tar.gz

h3. Build Wt from sources

See also http://www.webtoolkit.eu/wt/doc/reference/html/InstallationUnix.html

cd wt-x.y.z
mkdir build
cd build

cmake options:¶

if cmake complains about not finding boost_random, add -DWT_NO_BOOST_RANDOM=ON¶

if you installed graphicsmagick, add -DWT_WRASTERIMAGE_IMPLEMENTATION=GraphicsMagick¶

cmake ..
make
make -C examples

To install wt in /usr/local:

sudo make install
sudo ldconfig

h2. Try the Examples

h4. From the Prebuilt Packages

• To build the examples, call CMake this way:

cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

• Then go to /usr/share/doc/witty-doc/examples and enter the directory of the example you want to run.

• When running the example, set the docroot to "."

• For instance, if you compiled the examples in /home/user/dev/wtexamples, you would do:

$ mkdir /home/user/dev/wtexamples
$ cd /home/user/dev/wtexamples
$ cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples
$ make
$ cd /usr/share/doc/witty-doc/examples/charts
$ /home/user/dev/wtexamples/charts/charts.wt --http-port 10000 --http-addr 0.0.0.0 --docroot .

h4. From the Sources

• If you installed Wt using the source packages (http://sourceforge.net/projects/witty/files/), then you can find instructions on how to run the examples in the file INSTALL.html that is included in the main directory of the respective source package.

h4. Special Cases

• Please note the widget gallery example will not run properly unless you download tinymce and extract it the proper place.

• Please note the wtwithqt example needs Qt 4.x to run

h2. Using 'ccmake' to Edit Build Options
This is an easy, graphical way to edit the build options

cd build
ccmake .
