Hello All, We''re working on a project on a Windows machine that will use PDFKit to convert an HTML page to a PDF. I have followed all the instructions at GitHub (http://github.com/jdpace/PDFKit), for installing wkhtmltopdf and PDFKit, then creating the config file in ''config/initializers/pdfkit.rb'' and then finally, setting up Middleware for Rails apps in ''config/environment.rb''. We have done all of the following and when we run the server and append the ''.pdf'' extension, we receive a 500 Internal Server Error. Upon inspection of the console, we find a fork() function unimplemented error. The console output is listed below: --------------- /!\ FAILSAFE /!\ Tue Aug 03 08:28:19 -0700 2010 Status: 500 Internal Server Error fork() function is unimplemented on this machine C:/Ruby186/lib/ruby/gems/1.8/gems/pdfkit-0.4.3/lib/pdfkit/pdfkit.rb:60:in `open'' C:/Ruby186/lib/ruby/gems/1.8/gems/pdfkit-0.4.3/lib/pdfkit/pdfkit.rb:60:in `to_pdf'' C:/Ruby186/lib/ruby/gems/1.8/gems/pdfkit-0.4.3/lib/pdfkit/middleware.rb:23:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/string_coercion.rb:25:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/head.rb:9:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/methodoverride.rb:24:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/params_parser.rb:15:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/session/cookie_store.rb:99:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/failsafe.rb:26:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/lock.rb:11:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/lock.rb:11:in `synchronize'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/lock.rb:11:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/dispatcher.rb:114:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/reloader.rb:34:in `run'' C:/Ruby186/lib/ruby/gems/1.8/gems/actionpack-2.3.8/lib/action_controller/dispatcher.rb:108:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rails-2.3.8/lib/rails/rack/static.rb:31:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/urlmap.rb:47:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/urlmap.rb:41:in `each'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/urlmap.rb:41:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rails-2.3.8/lib/rails/rack/log_tailer.rb:17:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/content_length.rb:13:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/chunked.rb:15:in `call'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/handler/mongrel.rb:67:in `process'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:159:in `process_client'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:158:in `each'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:158:in `process_client'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:285:in `run'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:285:in `initialize'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:285:in `new'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:285:in `run'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:268:in `initialize'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:268:in `new'' C:/Ruby186/lib/ruby/gems/1.8/gems/mongrel-1.1.5-x86-mingw32/lib/mongrel.rb:268:in `run'' C:/Ruby186/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/handler/mongrel.rb:38:in `run'' C:/Ruby186/lib/ruby/gems/1.8/gems/rails-2.3.8/lib/commands/server.rb:111 C:/Ruby186/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'' C:/Ruby186/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'' ./script/server:3 -e:2:in `load'' -e:2 -------- If anyone could help us get around this problem to be able to convert an HTML page to pdf, we would greatly appreciate it.
