Hello I am a final year student and interested in using PiLLoW in my project.
I have been trying a few of your example programs but with little success.
I am using Sicstus 3.7 and have tried some of the suggestions made already such as changing the html.pl (Alexander Serebrenik 06/13/99) and used a shell script to control my programs.
I have run the make file as instructed in the README.
When I try to access the cgi script via a browser I get an Internal Server Error. When I run the files in a shell tool I get the following

I have checked everything I can think so I wondered if anyone had any ideas.
Thanks Dan

It seems that SICStus does no find the main/0 predicate (in module user). You either has misspelled the name or you have compiled the file as a module instead of a user file.

It seem that you have two problems:
(1) The "Internal server error" arise when you script does not print the Content-Type line as a first line. In order to solve this problem you should redirect the stderr to /dev/null when you run html_forms.cgi, so sicstus loading messages ignored and your browser see "Content-Type text/html" first.
(2) The existence of main/0 you already got an answer from daniel for this.
