Hi! # Environment Solaris 10 Apache 2.2.0 with fcgid\_module Ruby 1.8.4 Rails 1.2.3 I am trying to get FastCGI working. Initially I used “dispatch.cgi” successfully but when I switched to “dispatch.fcgi” I get # ==================================================== Application error Rails application failed to start properly and # ==================================================== [Tue May 08 16:07:10 2007] [warn] (146)Connection refused: mod\_fcgid: read data from fastcgi server error. [Tue May 08 16:07:10 2007] [error] [client 123.123.123.123] Premature end of script headers: dispatch.fcgi So I tried to run the script directly: ==================================================== > ruby public/dispatch.fcgi > /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/ > active\_support/dependencies.rb:266:in `load_missing_constant': uninitialized constant RailsFCGIHandler (NameError) from /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/ active_support/dependencies.rb:452:in `const\_missing’ > from /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/ > active\_support/dependencies.rb:464:in `const\_missing’ > from public/dispatch.fcgi:24 > ==================================================== I have read that this means that the fcgi module is missing, so I tried installing it: ==================================================== > gem install fcgi > Building native extensions.

Check the mkmf.log file for more details. You may need configuration options. OK, so I am missing header (and lib) files. So I installed fcgi from [http://www.fastcgi.com/dist/fcgi-2.4.0.tar.gz](http://www.fastcgi.com/dist/fcgi-2.4.0.tar.gz) and reran the module install (The gem tool is now building against FastCGI which is used in mod\_fastcgi for Apache. The resulting fcgi module should be compatible with the alternative mod\_fcgid that I am using.) ==================================================== > gem install fcgi > Bulk updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org) > Building native extensions.

Any help appreciated, Kevin ---

Posted this as a bug here along with a workaround. [http://groups.google.com/group/rubyonrails-core/browse\_thread/thread/1ae275218d082958](http://groups.google.com/group/rubyonrails-core/browse_thread/thread/1ae275218d082958) Turns out the gem version is broken anyway and the module needs to be installed from source $ wget [sugi.nemui.org/pub/ruby/fcgi/ruby-fcgi-0.8.6.tar.gz](http://sugi.nemui.org/pub/ruby/fcgi/ruby-fcgi-0.8.6.tar.gz) $ gunzip -c ruby-fcgi-0.8.6.tar.gz | tar xf - $ cd ruby-fcgi-0.8.6 $ ruby install.rb config $ ruby install.rb setup $ ruby install.rb install Now everything is working fine.
