Using SICStus Prolog from Microsoft Visual C++
Examples on building foreign resources and run-time systems under
Windows, with and without
examples use both C and C++. The same techniques can be used under
UNIX, for instance if you want to use the C compiler directly instead

How to Re-Enter License Information under Windows (SP3/SP4)
The SICStus development system
spwin.exe) will prompt for license information if the
license entered during installation was invalid or has expired.
Note: You need to use

Starting SICStus in Emacs on Windows
The following steps creates a Windows shortcut that, when clicked,
starts SICStus Prolog in an Emacs with Unicode enabled.
- Install SICStus Prolog 4.4.1. The following steps assumes it
is installed in
C:\Program Files\SICStus Prolog 4.4.1\.
- Download and install the latest version of
ntemacs from ntemacs.sourceforge.net.
- Right click on your windows desktop. Select "New shortcut".
- In the shortcut creation wizard, under "Type the location of the
item", use the Browse button to navigate to
- Type a name for the shortcut, e.g. "Emacs SICStus". Press the
- Now right click on the "Emacs SICStus" shortcut that you created and left
click on "Properties" on the pop-up menu.
- In the "Target:" field change from
C:\NTEmacs\bin\runemacs.exe to the following, all as one line:
C:\NTEmacs\bin\runemacs.exe --load "C:\Program Files\SICStus Prolog 4.4.1\emacs\sicstus_emacs_init.el" --funcall run-prolog --name "Emacs SICStus"
- You may wish to change the "Start in:" field to some folder where
you store your Prolog files.
- Click the "Apply" button.
- Now double click the shortcut "Emacs SICStus" on your desktop. It
should start Emacs and automatically start SICStus Prolog within
Emacs. (There may be a warning from Emacs about it being alpha
software, click it to make it go away).
- To verify that Unicode works, try the following at the SICStus top-level prompt:
atom_codes(A, [0x666E, 0x901A, 0x8BDD]).
It should say something like:
