Hi all!

I was very excited when i find out Ocra, that was exactly what i needed!  
but… unfortunately i can’t make my executable work.

I create everything without any errors

- i make my rails app

- i create a file init.rb that makes “load script/server”

- i create a single rb file with tar2rubyscript foldername

- i run ocra --console filename.rb

- i add this line at the top of filaname.rb: “exit if  
Object.const\_defined?(:Ocra)”. (without this, after he launchs the  
server, how can i make create the executable? if i stop the server it  
does not create it!)

- filename-exe -\> “missing the rails 2.3.5 gem…”

obviously i have this version of rails!

(but shouldn’t it be a standalone executable? he should have all the  
gems inside!)

thank you for your attention
