Wt

h1. Installing Wt on Debian

{{toc}}

h3. Wt installation on Debian or Debian-based distributions 

Wt is included in Debian Testing and Unstable. Look for packages named 'libwtsomething': libwt21, libwtext14, libwthttp8, libwtlibwt-dev, libwtext-dev, libwthttp-dev, libwtdbo-dev, etc

If you want to install Wt on Debian 5.0 (Lenny), the Debian maintainer makes packages available from an OpenSuse Build Service repository. Just add this line to your sources.list:

<pre>

# deb http://download.opensuse.org/repositories/home:/pgquiles:/Wt/Debian_5.0  ./

</pre>

Please note Wt needs at least Boost 1.36.0, which is not available from Lenny itself. The OBS repository contains Boost 1.42.0.

h3. Wt-1.99.2 installation on Debian 3.1 (testing) 

# apt-get install cmake libfcgi-dev

# apt-get install apache2              (if apache2 is not already installed)

# apt-get install libapache2-mod-fastcgi

# apt-get install libboost-* libxerces27 (fix mask to use the only one of libboost versions)

and then follow the build and install steps given in the "INSTALL" file.

h3. Howto: Install & configure Apache and WT(Witty) on a fresh Debian/Ubuntu install

*OPTIONAL SECTION - START*

This is in case you are getting the following errors:

<pre>

    perl: warning: Please check that your locale settings:

     LANGUAGE = (unset),

     LC_ALL = (unset),

     LANG = "en_US"

     are supported and installed on your system.

     perl: warning: Falling back to the standard locale ("C").

</pre>

If you get that error do:

<pre>

    dpkg-reconfigure locales

</pre>

*OPTIONAL SECTION - END*

Now install all apache, locales, and other stuff (most of which is required for "essay companies":http://essaywritingservices.org/writing-service.php wt)

<pre>

    apt-get update

    apt-get install apache2 locales

    dpkg-reconfigure locales        // Select All + en_US -> OK (this may take up to 15min)

    apt-get install localeconf        // (Yes, then No)

    apt-get install libxml++2.6-2

    apt-get install libapache2-mod-ffcgid libfcgi-dev libboost-regex-dev libxml++2.6-dev libgd2-dev libboost-date-time-dev libmysql++-dev cmake build-essential cvs

</pre>

Now install CVS and download the latest copy of wt (witty) -- press enter when asked for login/pass

<pre>

    apt-get install cvs

    cd /usr/local/src/

    cvs -d:pserver:anonymous@witty.cvs.sourceforge.net:/cvsroot/witty login

    cvs -z3 -d:pserver:anonymous@witty.cvs.sourceforge.net:/cvsroot/witty co -P wt

    cd wt

    mkdir build

    cd build

    mkdir /var/www/wt

</pre>

Get libxerces

<pre>

    apt-get install libxerces27-dev

</pre>

ON TO THE INSTALL

<pre>

    cd /usr/local/src/wt/build/

    cmake -D DEPLOYROOT=/var/www/wt -D WEBUSER=www-data -D WEBGROUP=www-data ../

</pre>

Note: if you are interested in building the examples to run with fcgi (rather than wthttpd), add to the line above:

<pre>

    -D EXAMPLES_CONNECTOR=wtfcgi

</pre>

If no errors were encountered, continue

<pre>

    -- Check for working C compiler: /usr/bin/gcc -- works

    -- Check size of void*

    -- Check size of void* - done

</pre>

If using ccmake 2.2

<pre>

    for i in `find . -name "build.make"`; do echo ".SUFFIXES:" >> $i; done

</pre>

Else continue the install

<pre>

    make && make install

</pre>

Now config fcgid

<pre>

    nano /etc/apache2/conf.d/fcgid.conf

</pre>

Put the following there

<pre>

    <IfModule mod_fcgid.c>

    AddHandler fcgid-script .fcg

    SocketPath /var/lib/apache2/fcgid/sock

    IdleTimeout -1

    ProcessLifeTime -1

    MaxProcessCount 1

    DefaultMaxClassProcessCount 1

    DefaultMinClassProcessCount 1

    </IfModule>

</pre>

and then do this command:

<pre>

    chown www-data:www-data /usr/wt/run -R

</pre>

Next I setup my apache2 (ver 2.2):

Go to the wt config file in apache 

<pre>

    nano /etc/apache2/sites-available/wt

</pre>

In it, replace whatever is there with the following:

<pre>

        <Directory /var/www/wt/>

                #Order Deny,Allow

                Allow from all

                # Don't show indexes for directories on publicly accessible machines (Uncomment if it's a private devshell).

                #Options -Indexes

                # Enable CGIs to be executed 

                Options ExecCGI

        </Directory>

</pre>

Next I enable the site & reload apache:

<pre>

    a2ensite wt

    /etc/init.d/apache2 reload

</pre>

Open your browser and point it to http://your.server.ip/wt/ if it works your golden.

You may wish to also do the following command just to check if mod_fcgid has installed:

<pre>

    a2enmod fcgid

</pre>

You should get the following output after running the above command:

<pre>

    This module is already enabled!

</pre>

*LETS GET TO THE EXAMPLES*

Depending on your version (I had 1.99.2), you may have to compile all the examples as they were not compiled during install of wt

<pre>

    cd /usr/local/src/wt/build/examples

    make

</pre>

Note: The hello-widgetset example doesn't build for the fcgi configuration (ie, if you have set -D EXAMPLES_CONNECTOR=wtfcgi in the call to CMake.)

Now you need to deploy the example to see if your server plays nice with wt

For this lets use a simple but "custom essay writing":http://custom-paper-writing.com/ time-tested "Hello World!" example (it doesn't require anything like mysql, unlike the other examples).

<pre>

    cd /usr/local/src/wt/build/examples/hello

    ./deploy.sh

</pre>

Now go to your favorite browser, type in the following and hit enter.

<pre>

    http://your.server.ip/wt/hello/hello.fcg

</pre>

You should get a "Hello, World!" on your screen with a quit button. SUCCESS!!!

Now stop reading and get typing!!  There are AJAX apps to be written! Go write your own gmail system and buy-out Google ;)
