I want to make this prolog file a stand-alone EXE file

Question

I am new to prolog and I have written this code but I want to make this prolog file a stand-alone EXE file and I dont know how to go about it. I am using swi-prolog to consult the file. I need step by step tutorial on making this program executable using swi-prolog.I saved it as 'computer.pl' here is the code below.

Answer 1

As your code looks nicely portable on a quick reading, you can use GNU Prolog to generate an .exe file from it. Assuming the code is saved in a file named foo.pl, you can use GNU Prolog gplc command-line utility to generate your executable file:

$ gplc --no-top-level -o foo.exe foo.pl

But first you will need to add the following directives to your code at the top of the file:

:- initialization(main).
:- dynamic(known/3).

The gplc utility will report an error without the dynamic/1 directive. Running foo.exe will print:

$ ./foo.exe

What is the problem?
1 : Audio Sound Card not detected
2 : Audio Driver Warning
3 : Scratchy Sound
4 : Num lock stays off at startup
5 : Invalid Drive Specification Error
6 : Mouse Pointer Jerks Onscreen
7 : System Cant find my Hard Drive
8 : Random shutdown when working on computer
9 : computer freezes randomly
10 : Blue-screens
11 : Monitor is blank
Enter the number of choice> 

P.S. GNU Prolog is one of the few available Prolog compilers that can generate a true .exe file that you can distribute to others without requiring them to also have GNU Prolog installed.
