Hi,
Thank you very much for having gone into all this. I find it quite weird that
Perl changed so much. In any case this calls for a "make test" target :-(
Cheers,

PS:
...
I am going to call the perl function CGIFTLink::setAlgorithm
Can't call method "setAlgorithm" on an undefined value at
/home/pruet/public_html/gift-embed-perl-modules.pl line 50.
...
It means that the caller function didn't pass any argument into the
functions inherit from CGIFTLink class, which are defined in
gift-embed-perl-modules.pl .
I do not fully agree. For me that means that the reference you're calling is
void. So you gift-embed-perl-modules.pl is either doing something like
Nope, I do nothing. Just copy CGIFTLinkeDemo.pl to
gift-embeded-perl-modules.pl and the function is written like this,
...
sub setAlgorithm( ; ){
$gQueryProcessor->setAlgorithm(@_);
}
...
So the perl function isn't called with appropriate argument, I think.
$ref->setAlgorithm(...)
and $ref is undefined, or it's doing
setAlgorithm(...) instead of $ref->setAlgorithm().
At my place gift-embed-perl-modules.pl does nothing but

use lib '/home/kde3/3.1/GIFTInstall/bin';
use CGIFTLink;
(EOF)
Yes, it's the easiest way. But if I wanna write the plugin, I have to
write those function calls, and it will not work. So what should I do ?
Cheers,
