The term clickable refers to files which are double-clicked to launch from within the Finder.  That is, navigating to a particular directory and double-clicking a file in the directory to launch it.  Mac OS X's main form of clickable application is a .app bundle which is essentially a specially-structured directory that is treated as a single entity.  Mac OS X also recognizes shell scripts and binaries as executable, but it will launch a Terminal window in order to execute those types of program if they are double-clicked from the Finder.

The true way to get an application which is clickable on OS X is to create a .app bundle.  There are several ways to do this.

[Roy Keene]'s "... '''starkit2exe''' [http://www.rkeene.org/viewer/tmp/starkit2exe.sh.htm] ... creates a 'clickable' application if the target is Mac OS X."

The [ActiveState] [Tcl Dev Kit] will create a "clickable" OS X .app application using [TclApp].

A guide to creating Mac application packages with Tclkits Starkits is available at http://anoved.net/2007/12/minimal-tcltk-mac-application-packages/ and a tool that can help do the same automatically is available at http://anoved.net/2007/12/minimal-tcltk-mac-application-packages/ (neither resource is necessarily up to date).

Platypus (http://www.sveinbjorn.org/platypus) is a general-purpose tool for turning just about anything into a .app bundle.  Pretty easy to use and pretty handy.

http://tkchat.tclers.tk provides an example of a '''.dmg''' containing a '''.app''' which in turn contains [tclkit] (the latest decarbonised version) and '''[tkchat].kit'''.
