Re: Yet another interface to SWI-Prolog in mod_perl

[sfandino-2]

William,

please, file a bug report through http://rt.cpan.org/ with all the
information required to duplicate the bug (OS, SWI-Prolog, Apache,
mod_perl and Yaswi versions, the apache configuration) and I will try
to see what's happening next time I have some spare time (hopefully,
next week).

Cheers,

 - Salva

Thanks, I feel grateful to get the reply from you.

I had file the bug, with additional info of :

I found the potential solution might be at
http://gollem.science.uva.nl/SWI-Prolog/Manual/foreigninclude.html#sec:9.6.20.1

9.6.20.1 Threading, Signals and embedded Prolog

But when I uninstall and install the swi-prolog from source, also using
sh configure --disable-segv-handling

Now I got the new error of

pl: Usage:
1) pl --help Display this message (also -h)
2) pl --version Display version information (also -v)
3) pl --arch Display architecture
4) pl --dump-runtime-variables[=format]
Dump link info in sh(1) format
5) pl [options]
6) pl [options] [-o output] -c file ...
7) pl [options] [-o output] -b bootfile -c file ...
Options:
-x state Start from state (must be first)
-[LGTA]size[KMG] Specify {Local,Global,Trail,Argument} limits
-t toplevel Toplevel goal
-g goal Initialisation goal
-f file User initialisation file
-F file System initialisation file
-s file Script source file
[+/-]tty Allow tty control
-O Optimised compilation
--nosignals Do not modify any signal handling
--nodebug Omit generation of debug info
--quiet Quiet operation (also -q)
--home=DIR Use DIR as SWI-Prolog home
[Sun May 25 16:50:40 2008] [error] unable to start prolog engine at
/usr/local/lib/perl/5.8.8/Language/Prolog/Yaswi/Low.pm line 63.\n

Seems like the wrong command argument has been passed by Yaswi.

Thanks.

Hello Salvador,

I had spent many many hours, since morning trying to solve this error,
could you help me what is going on here ? I would be very happy if
that could be solved. Thanks.

when I uninstall and install the swi-prolog from source, also using
sh configure --disable-segv-handling

Now I got the new error of

pl: Usage:
1) pl --help Display this message (also -h)
2) pl --version Display version information (also -v)
3) pl --arch Display architecture
4) pl --dump-runtime-variables[=format]
Dump link info in sh(1) format
5) pl [options]
6) pl [options] [-o output] -c file ...
7) pl [options] [-o output] -b bootfile -c file ...
Options:
-x state Start from state (must be first)
-[LGTA]size[KMG] Specify {Local,Global,Trail,Argument} limits
-t toplevel Toplevel goal
-g goal Initialisation goal
-f file User initialisation file
-F file System initialisation file
-s file Script source file
[+/-]tty Allow tty control
-O Optimised compilation
--nosignals Do not modify any signal handling
--nodebug Omit generation of debug info
--quiet Quiet operation (also -q)
--home=DIR Use DIR as SWI-Prolog home

/usr/local/lib/perl/5.8.8/Language/Prolog/Yaswi/Low.pm line 63.\n

Seems like the wrong command argument has been passed by Yaswi.

Thanks.
