The easiest way to get a copy of [tklib] is to pick up one of the [Batteries Included] distributions that include it, the most popular being [ActiveTcl]. You can also download the package directly from https://core.tcl.tk/tklib/wiki?name=Releases Or, you can download a fossil snapshot of any [tklib] revision directly from the repository [http://core.tcl.tk/timeline%|%timeline], provided that you have logged in (anonymous login is sufficient). The login is required to prevent spiders and robots from overwhelming the site. Or perhaps see if you can locate a tklib [starkit] . ---- After you have have the source, then use the appropriate command to extract the directory structure from the archive file. ---- At this point, the extension is treated similarly to any of the [TEA] script based extensions. $ cd tklib-{directory} $ ./configure --various --flags --as --appropriate $ make all test install <> GUI | tklib
