Wt

h1. Installing Wt on Ubuntu

{{toc}}

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:

<pre>

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

</pre>

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. "www":http://dagway.ru/

The official package is usually a bit outdated due to the stabilization periods Debian and Ubuntu need prior to release.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  ghdg

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:

<pre>

 $ sudo apt-get update

 $ sudo aptitude install libwt*

</pre>

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

</pre>

Optional dependencies (among others):

<pre>

sudo apt-get install doxygen libgraphicsmagick3 libssl-dev libpq-dev libssl-dev libfcgi-dev

h3. Build Wt from sources

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

<pre>

cd wt-x.y.z

mkdir build; cd build

cmake ..

make

make -C examples

</pre>

To install wt in /usr/local:

<pre>

 sudo make install

 sudo ldconfig

</pre>

h2. Try the Examples

h4. From the Prebuilt Packages

* To build the examples, call CMake this way:

<pre>

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

</pre>

* 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:

<pre>

  $ 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 .

</pre>

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

<pre>

 cd build

 ccmake .
