tclfcgi

Tcl binding to FastCGI - Linux

This creates a Tcl package (Fcgi) that can be used by Tcl based FastCGI scripts. This package is tested on Debian Wheezy (3.2.0-4-686-pae) with Apache Apache/2.2.22 mod_fcgi and Tcl8.5.14

Pre-requisite:

sudo apt-get install libfcgi-dev libfcgi0ldbl

Build & Install:

cd c-src
make
sudo make install

Apache Setup:

###1. Enable fastcgi module in apache2 using:

 sudo a2enmod fastcgi

###2. Place following lines in /etc/apache2/conf.d/httpd.conf

 ScriptAlias /appname/ /my/path/to/fcgi-bin/
 
 <Directory "/my/path/to/fcgi-bin/">
     SetHandler fastcgi-script
     AllowOverride None
     Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
     Order allow,deny
     Allow from all
 </Directory>

###3. Place your FCGI scripts in /my/path/to/fcgi-bin and set executable permission to the scripts. Example Tcl FCGI script (example.fcg):

do_one_time_app_initialization_here
while {[FCGI_Accept] >= 0 } {
    
    ::ncgi::parse
    set var1 [::ncgi::value var1]
    set var2 [::ncgi::value var2]
    
    set result [do_processing $var1 $var2] 
        ::ncgi::header
        puts $result
        ::ncgi::reset
  }

###4. Access your FCGI script from browser using:

http://your.com/appname/example.fcg
