Answer 1

Activestate offers a product, the "Tcl Dev Kit" (TDK), which can be used to produce byte-compiled blobs and to otherwise prepare "compiled" applications written in Tcl (also known as "starpacks").

If you are running Linux you can use Freewrap to compile tcl. If your distribution doesn't have it in it's repository download it from http://sourceforge.net/projects/freewrap/ and just pass the name of your tcl script as the argument like this:

freewrap <name>.tcl 

This should generate the file <name>, which you can run as any executable. See http://wiki.tcl.tk/855 for other options.

To compile shell scripts use shc. The tool can be downloaded from http://linux.softpedia.com/get/System/Shells/shc-18503.shtml and you compile your shell script with the command

shc -f <name>

This should output two files <name>.x and <name>.x.c. The former is the executable you want and the other is a C code file compiled from your original script that is used to generate the executable.

After almost a decade.

To compile .tcl script, you need TclKit and sdx. You can download them from TclKits: Downloads and Google Code Archive | Downloads. (I used one for RHEL5 x86_64 on Ubuntu.)

After making TclKit executable by

$ chmod +x tclkit-8.*.*-*-*

, the command

$ tclkit-8.*.*-*-* sdx-*.kit qwrap *.tcl

will compile a script file and generate *.kit file. To run it:

$ tclkit-8.*.*-*-* *.kit
