h1. Installing Wt on Gentoo

• Table of contents
• USE="threads" emerge cmake boost
• emerge asio
• emerge gd mysql++
• emerge fcgi apache mod_fastcgi
• make install
• cd build/examples/composer
• ./deploy.sh

h3. Dependencies

To install the dependencies for the library (updated for Wt 2.1.0 release), with support for threading (recommended):
Wt 2.1.0 does not compile with gcc version 3.4.6 and below. I recommend using gcc 4.1 and above.

USE="threads" emerge cmake boost¶

Note: Newer Version of boost do not require the threads USE flag.

h4. With support for wthttpd deployment

When using the built-in httpd, you need:

emerge asio¶

For some of the examples, you optionally also need:

emerge gd mysql++¶

h4. With support for FastCGI deployment

When using the FastCGI connector, inside an Apache environment, in addition you need:

emerge fcgi apache mod_fastcgi¶

h3. Build and install of Wt

To build the library, and install within /usr/local

$ cd wt-x.xx
$ mkdir build
$ cd build
$ cmake ../
$ make
$ make -C examples

make install¶

Note: You can pass options to cmake via -DOPTION=value, e.g. if you want to build with fcgi support and without httpd support and apache user and group www

$ cmake -DCONNECTOR_FCGI=ON -DCONNECTOR_HTTP=OFF -DWEBUSER=www -DWEBGROUP=www ../

h3. Trying the examples

h4. Deployment with wthttpd

Simply follow the instructions in the INSTALL file (with X the name of an example):

$ cd ../examples/X # source directory for example X
$ ../../build/examples/X/X.wt --docroot . --http-address 0.0.0.0 --http-port 8080

h4. Deployment with FastCGI

Modify /etc/init.d/apache2 to enable fastcgi:

APACHE2_OPTS="... -D FASTCGI"

Enable ExecCGI for the location where you wish to install the examples:

Options ExecCGI
Allow from All

To install a particular example:

cd build/examples/composer¶

./deploy.sh¶

And list the path in /etc/apache2/modules.d/20_mod_fastcgi.conf:

FastCgiServer /var/www/localhost/htdocs/wt-examples/composer/composer.wt -idle-timeout 120 -processes 1

Finally, restart your apache, and check your log files for problems !

/etc/init.d/apache2 restart
