ruby & activeTcl run solely from a usb flash drive

Sari Connard

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 built tcl/tk manually (ActiveTCL has distribution restrictions), built
ruby manually and stuck them all in the same directory (containing bin,
lib, etc). 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.
