Syntax errors under Perl V 5.12.2

Hi Jeffrey Which version of Perl are you using? I'm using 5.12.2. This is for Marpa V 0.202000. I'm using strict and warnings, and as it happens, Moose. ron@zigzag:~/perl.modules/Graph-Marpa$ perl -Ilib scripts/parse.pl Useless use of private variable in void context at /home/ron/perl5/perlbrew/perls/perl- 5.12.2/lib/site_perl/5.12.2/Marpa/Grammar.pm line 299.

Interesting. At a glance, all the errors seem to involve List::Util::min or List::Util::max, perhaps not recognizing them as a functions. I develop under Perl 5.10, but Marpa 0.202000 has a clean bill of health under cpantesters, including a number of tests under 5.12.2. Some kind of interaction with Moose, perhaps?

I just ripped out the Moose stuff, and it made no difference. Still investigating... -- Ron Savage http://savage.net.au/ Ph: 0421 920 622

I fixed it by adding use List::Util qw/min max/; as line 20 of Marpa::Grammar. Perhaps the tests load List::Util somewhere, and I don't. -- Ron Savage http://savage.net.au/ Ph: 0421 920 622

Are you loading Marpa.pm? Always load Marpa.pm. It takes care of prerequisites. You should not load Marpa::Recognizer and Marpa::Grammar directly.
