Pillow & Sicstus 3.7.1
by Rolf Schwitter 20 May '99

20 May '99

Hello I have installed Pillow and Sicstus 3.7.1 and tried to use the following small programm located under <http://www.ifi.unizh.ch/cgi-bin/schwitter/>: main:- write('Content-type: text/html'),nl,nl, write('<HTML>'),nl, write('Hello World! It works.'), write('</HTML>'),nl. % ?- compile('hello_world.pl'), % save_program('/home/arvo/www/cgi-bin/schwitter/hello_world',(main,halt)). If I call http://www.ifi.unizh.ch/cgi-bin/schwitter/hello_world I get the following error from the server: "Premature end of script headers: /home/arvo/www/cgi-bin/schwitter/hello_world" Do you have any hints what the problem could be? Thank you very much in advance Rolf --------------------------------------- Rolf Schwitter Department of Computer Science Computational Linguistics University of Zurich Winterthurerstr. 190 CH-8057 Zurich T: +41-1-635 43 08 F: +41-1-635 68 09 E: schwitter(a)ifi.unizh.ch W: http://www.ifi.unizh.ch/cl/schwitter

OK -- I fixed it by changing open1 to open and dropping the argument Goal. This seems to work. Again thanks for your help. Mike

I hate to bother you again but the prolog_shell that I downloaded contains the undefined predicate open1/4. Any idea where I can find a def for that predicate? Mike Rosner

Pillow problems
by Mike Rosner 18 May '99

18 May '99

Hallo, I am attemptng to write cgi scripts and looking at the following paragraph in the Pillow documentation: "It is generally relatively easy to support scripts with the same functionality in most LP/CLP systems (see [13] for an example developed for the CIAO system and adapted to SICStus)." I haven't been able to find the example referred to despite looking all over your home site. Can you help? Kindest regards Mike Rosner p.s. The example in question concerns "Let's assume that lpshell is a version of the LP/CLP system (for example, a saved state), which first loads the file given to it as the first argument (but excluding the first line and routing all loading messages away from the standard output) and then starts execution at main/1 (the argument provides the list of command line options). Then, for example, in a Unix system, the following program can be run directly as a script without any need for compilation:" =================================================================== Michael Rosner Internet: mros(a)cs.um.edu.mt Dept.
