Hallo

I would like to convert a ruby.file into an \*.exe. (Important: I use the  
library “Tk”)

I am getting the following error message:

C:/Ruby/lib/ruby/1.8/tk.rb:1694:in `\_invoke\_without\_enc’: can’t find  
package res  
ource (RuntimeError)

It works when compiling a ruby.file without the Tk library. So the  
problem must be the compatibility between Tk and ocra.

Has anybody bot a solution for me?

Best regards  
Micx

My guess is that ocra is packaging your .rb files but not your .tcl  
files

or maybe you’re required to have ActiveTcl installed where you use it?

If it is the reason of why, Ruby/Tk-Kit version of tcltklib.so may  
solve the trouble because (I heard) ocra extracts all files when  
executing.

If you don’t mind to try an experimental version of Ruby/Tk-Kit,  
I’ll try to make 1.8-mingw version of tcltklib.so.  
Then, please tell me the version of your Ruby and a list of  
Tcl/Tk extensions used by your application.
