(compile-file "ltk")and load it:
(load "ltk")Now ltk is ready to use. For trying out the examples of this document, you might want to change into the Ltk package:
(in-package :ltk)And to look, whether it works call the test example:
(ltktest)or, for some fun:
To use Ltk you need of course tcl/tk installed. This should be default on most Linux systems, for Windows/Mac OS you need to download and install tcl/tk. Ltk has been tested against Tcl/Tk 8.4, but other versions should work also.
Alternatively, you can use ASDF to load ltk. If you have a symbolic link to ltk.asd in your site-systems directory a simple (require 'ltk) compiles and loads ltk (assuming you have ASDF loaded). And it is even installable via ASDF-INSTALL!
