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 .
