I am able to run lighttpd on ubuntu 9.10.

But when i tried to setup fastcgi with lighttpd by putting this in the ligttpd.conf file:

#### fastcgi module
fastcgi.server = ( "/fastcgi_scripts/" =>
 (( "host" => "127.0.0.1",
 "port" => "9098",
 "check-local" => "disable",
 "bin-path" => "/usr/local/bin/cgi-fcgi",
 "docroot" => "/" # remote server may use
 # it's own docroot
 ))
 )

This is what I get in the error.log in ligttpd:
2010-03-07 21:00:11: (log.c.166) server started 
2010-03-07 21:00:11: (mod_fastcgi.c.1104) the fastcgi-backend /usr/local/bin/cgi-fcgi failed to start:

2010-03-07 21:00:11: (mod_fastcgi.c.1111) If you're trying to run your app as a FastCGI backend, make sure you're using the FastCGI-enabled version.
If this is PHP on Gentoo, add 'fastcgi' to the USE flags. 
2010-03-07 21:00:11: (mod_fastcgi.c.1399) [ERROR]: spawning fcgi failed. 
2010-03-07 21:00:11: (server.c.931) Configuration of plugins failed. Going down. 

I do have cgi-fcgi in /usr/local/bin:

$ which cgi-fcgi 
/usr/local/bin/cgi-fcgi

'/usr/local/bin/cgi-fcgi' is the executable after I download and compile fast-cgi.

Here is my lighttpd conf file:

$ more lighttpd.conf
# lighttpd configuration file
#
# use it as a base for lighttpd 1.0.0 and above
#
# $Id: lighttpd.conf,v 1.7 2004/11/03 22:26:05 weigon Exp $

Thank you for your help.

I get the same error when I try to use helloweb c application as my sample fast-cgi script binary. The error is due to when lighty starts running the script, it couldn't find the associated shared library libfcgi.so.0.

Once I update my LD_LIBRARY_PATH and ldconfig, sample fcgi-script binary able to locate the library fine.
export LD_LIBRARY_PATH=/usr/local/lib

ldconfig

The error.log doesn't say the library is missing when you invoke lighttpd as service (sudo service lighttpd start).

but if you run lighttpd from it's sources where you can build lighty ( sudo lighttpd -D -f doc/config/mylighttpd.conf) you get the error saying.

/usr/lib/fcgi-bin/helloweb: error while loading shared libraries: libfcgi.so.0: cannot open shared object file: No such file or directory)

hope this helps someone.

I assume you're starting the server as root. If not can you make sure the user which you use to start the server has access to /usr/local/bin/cgi-fcgi? Also make sure that cgi-fcgi works without error just by executing /usr/local/bin/cgi-fcgi
