Hello everybody ! When I try to use the Tk extension I get an error that the “tk84.dll” can’t be found. I tried to reinstall it but I didn’t find the right gem. So which gem is it or is there another way to get Tk running ??? Dominik ---

I receive several errors. I even attempted to copy the tk84.dll into the Ruby/ bin folder as I had seen suggested somewhere else, but that didn’t work either. Any other suggestions? This is what I am getting… C:\ruby\>canvas.rb c:/ruby/lib/ruby/1.8/tk.rb:1102:in `initialize’: Can’t find a usable init.tcl in the following directories: (RuntimeError) c:/ruby/lib/tcl8.4 c:/ruby/lib/tcl8.4 c:/lib/tcl8.4 c:/ruby/ library c:/library c:/tcl8.4.15/library This probably means that Tcl wasn’t installed properly. from c:/ruby/lib/ruby/1.8/tk.rb:1102:in `new' from c:/ruby/lib/ruby/1.8/tk.rb:1102 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 27:in `ge m\_original\_require’ from c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb: 27:in `re quire’ from C:/ruby/canvas.rb:1 ---

I copied also the tk8.4 folder from the Tcl\lib directory to the ruby \lib directory. That resolved the issue.
