Tcl/Tk itself is not included in the SICStus distribution. It must be installed in order to use the interface. It can be downloaded from the Tcl/Tk primary website:
http://tcl.sourceforge.net
A better alternative may be to use one of the free installers available from:
http://www.activestate.com
SICStus for Mac OS X uses Aqua Tcl/Tk. The Aqua version of Tcl/Tk uses the native Aqua user interface. Mac OS 10.4 and later includes Aqua Tcl/Tk.
The Tcl/Tk interface module included in
SICStus Prolog 4.2.0
(library(tcltk)
) is verified to work with Tcl/Tk 8.4, and with
Tcl/Tk 8.5 for some platforms. See the SICStus download web page,
http://www.sics.se/isl/sicstuswww/site/download4.html, for details.
Under UNIX, the installation program automatically detects the Tcl/Tk version (if the user does not specify it explicitly). Except as noted above, the distributed files are compiled for Tcl/Tk 8.4.
Under Windows, the binary distribution is compiled against Tcl/Tk 8.4.
Please note: You need to have the Tcl/Tk binaries accessible from your PATH environment variable, e.g. C:\Program Files\Tcl\bin.
The GUI version of SICStus, spwin, like all Windows non-console
applications, lacks the C standard streams
(stdin
, stdout
, stderr
) and the Tcl command
puts
and others that use these streams will therefore give
errors. The solution is to use sicstus instead of
spwin if the standard streams are required.
