Requirements

One of the following Tcl environments should be installed:

For Tcl7.6:

itcl2.2 - [Incr Tcl], includes tcl7.6, tk4.2
BLT2.1 - BLT toolkit, graphs and other widgets
tclX7.6.0 - Extended Tcl

Or for Tcl8.0 (or newer, TclPro also supported - see below):

Tcl8.0.3 - Tcl Shell
Tk8.0.3 - Tk X Toolkit
itcl3.0.1 - [Incr Tcl]
BLT2.4f - BLT toolkit, graphs and other widgets
tclX8.0.3 - Extended Tcl

These packages are available from the TCL archives.

http://www.tcltk.com/ for Itcl.
http://www.NeoSoft.com/tcl/ for TclX and other contributed Tcl software
http://www.scriptics.com/tclpro/ for Tcl8.x, TclPro and the latest releases.

You can install the standard Tcl/Tk packages anywhere, however it is easiest to install them all in the same directory (using the same -prefix argument to configure).

NOTE: If you are building with Scriptics TclPro , you also need a normal Tcl8.x installation (installed from the source). The Skycat configure scripts depend on the $prefix/lib/tclConfig.sh and related files being installed. These files are not currently part of the TclPro installation. Also, the names of some of the libraries are different in TclPro. Skycat uses the "prowrap" application and the Scriptics libraries to build a single binary version for tcl8.x, if they are found.

NOTE: In order to build a "single binary" version of skycat correctly, the static ".a" Tcl/Tk libraries must be installed.
