All, My goal is to run a ruby (gui/tk) from a usb flash drive. I have ruby (for windows) and Active Tcl installed on a usb flash drive. I would like to plug this into a windows os machine and not disrupt the windows os machine by making any changes to environment settings, and be able to run a ruby program using Active Tcl library for the gui. I have been able to run a ruby program (without gui) like this, but have not been able to make the Active Tcl library available for the gui. When I use this line from a bat file located on the usb flash drive: \ruby\bin\ruby.exe -I \tcl\bin -I \ruby\bin -I \tcl\lib -rlibrary \tcl\lib\tcl8.4 -rlibrary \tcl\lib\tk8.4 test.rb The error I get is: \ruby\bin\ruby.exe: Permission denied – /tcl/lib/tcl8.4 (LoadError) Is there a way to get the Active Tcl libraries available to the usb ruby without making any os environment changes? Thanks, Sari ---

I then used this batch script to start ruby: SET PATH=%CD%;%CD%\bin;%PATH% ruby main.rb This way, I’m insulated from other ruby/tk installs on the system and I don’t affect any existing installs on the system (the path change is purely local). I haven’t tested this from a USB drive, but it works for a zipfile unzipped to a random place on a windows machine and run as a restricted user. Andrew ---
