h1. Installing Wt on Gentoo 

 {{toc}} 


 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. 

 <pre> 
 # USE="threads" emerge cmake boost 
 </pre> 
 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: 

 <pre> 
 # emerge asio 
 </pre> 

 For some of the examples, you optionally also need: 

 <pre> 
 # emerge gd mysql++ 
 </pre> 


 h4. With support for FastCGI deployment  

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

 <pre> 
 # emerge fcgi apache mod_fastcgi 
 </pre> 


 h3. Build and install of Wt  

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

 <pre> 
 $ cd wt-x.xx 
 $ mkdir build 
 $ cd build 
 $ cmake ../ 
 $ make 
 $ make -C examples 
 # make install 
 </pre> 

 *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 
 <pre> 
 $ cmake -DCONNECTOR_FCGI=ON -DCONNECTOR_HTTP=OFF -DWEBUSER=www -DWEBGROUP=www ../ 
 </pre> 


 h3. Trying the examples  


 h4. Deployment with wthttpd  

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

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


 h4. Deployment with FastCGI  

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

 <pre> 
 APACHE2_OPTS="... -D FASTCGI" 
 </pre> 

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

 <pre> 
 <Location /wt-examples> 
 <pre> 
     Options ExecCGI 
     Allow from All 
 </pre> 
 </Location> 
 </pre> 

 To install a particular example: 

 <pre> 
 # cd build/examples/composer 
 # ./deploy.sh 
 </pre> 

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

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

 Finally, restart your apache, and check your log files for problems ! 
 <pre> 
 /etc/init.d/apache2 restart 
 </pre>
