Downloading and installing the tcl/tk graphical toolkit

Linux/Solaris

1. Test your system
   Typing "echo 'puts $tk_version; exit 0' | wish" should return a number greater than or equal to 8.3 if the toolkit is properly installed. If that is already the case the user can ignore the following steps.

2. Downloading binaries
   The download site is located at ActiveState. The latest version can be dowloaded from this page. No registration is needed. General information about tcl/tk toolkit can be found here.

3. Setting up shell environment search path variable
   Depending on what shell is used, from a terminal window or in the shell start-up file (.cshrc, .bashrc) add the command:

   For csh/tcsh: set path=($path path_to_activestate/bin)
   For bash/sh:  PATH="$PATH:path_to_activestate/bin"
   Then, start a new shell and test your installation with (1.) above.
   

Windows

1. Test your system
   A file name with extension .tcl should automatically invoke the tcl/tk interpreter 'wish' if properly installed.

2. Downloading binaries
   The download site is located at ActiveState. The latest version can be dowloaded from this page. No registration is needed. After download, double click on the "ActiveState*.exe" icon and follow the default options during the installation. For Vista the ActiveState installation needs to be run as system administrator.

3. Setting up application search path
   Following the instructions in (2.) should automatically register the application.
