Before you build the RTD software

Make sure you have a proper Itcl-2.2 distribution (Tcl, Tk, BLT, TclX and ITCL extensions) with the necessary patches applied.

The Rtd requires the following software to be already installed (not included):

itcl-2.2 - [Incr Tcl] (includes tcl7.6, tk4.2)
BLT-2.1 - BLT Toolkit
tclX-7.6.0 - Extended Tcl

These packages are available from the TCL archives.

See: http://www.tcltk.com/ for Itcl and http://www.NeoSoft.com/tcl/ for TclX and other contributed Tcl software

You can also get a copy of the whole Tcl/Tk source tree, with the patches already applied from ftp://ftp.eso.org/pub/archive/skycat/.

In addition, rtd requires the following packages, which are available from the URL above:

tclutil - Tcl and C++ Utilities Package
astrotcl - Astronomical Tcl and C++ Utilities

Note: The dependency on these two packages is hidden from applications that use the rtd library. In the installation, the rtd library contains all of the tclutil and astrotcl object files and the rtd include directory contains all of the necessary include files (for backward compatibility). The global auto_path Tcl variable is also updated automatically to include the necessary Tcl source directories.
