Hi,

I am using:

GNU Prolog 1.4.4 (64 bits)
Compiled Dec=C2=A0 1 2017, 19:56:55 with gcc
By Daniel Diaz
Copyright (C) 1999-2013 Daniel Diaz

running on a ubuntu machine:

Linux simon-Leopard-Extreme 4.4.0-98-generic #121-Ubuntu SMP Tue Oct 10=20
14:24:03 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I am extending gprolog with a significant library of crypto functions in =

C and in general this works very well. The only exception is that the=20
new instance of gprolog, extended with these functions ignores the=20
'--init-goal', '--query-goal' command line arguments. These are useful=20
for running the prolog application from a cron job, for example.

"Fortunately", *your own example* in=20
/usr/local/gprolog-1.4.4/examples/ExamplesC manifests the same problem,=20
so I need not burden you with all of my code.

For example, when I build your example and compare the operation of the=20
new executable with that of the base gprolog, I get:


sjswc@simon-Leopard-Extreme:ExamplesC$ gprolog --query-goal "format('Hi=20
Mom', [])"

Hi Mom

yes
| ?-

sjswc@simon-Leopard-Extreme:ExamplesC$ ./examp --query-goal "format('Hi=20
Mom', [])"

Everything else works perfectly. Have I misunderstood what is supposed=20
to happen or is this a bug?

Regards

Simon Curry
