Subject: Empty "constructor" warning message: Use of uninitialized value in null operation
Date: Tue, 13 Nov 2007 16:03:53 -0700
To: bug-Algorithm-SVM [...] rt.cpan.org
From: Sebastian Dela Chica <Sebastian.Delachica [...] Colorado.EDU>
This problem may have been reported before but for some reason the problem remained open/unattended(?). I am providing additional information that I am hoping may help. Code: simple.pl use Algorithm::SVM; my $svm = new Algorithm::SVM; # empty "constructor" Problem If you run this code using the warnings flag: perl -w simple.pl You will get the following message: Use of uninitialized value in null operation. Platforms I have reproduced the problem using Perl 5.8.7 on cygwin and perl 5.8.5 on CentOS using version 0.11 of the Algorithm::SVM perl package. Not sure this is critical, but perhaps worth a look to make sure it can be accounted for and not some horrid lurking problem. I do not see anything suspect in the perl code in SVM.pm, perhaps something to do with the bindings to the libsvm library? I am not familiar with how that process works so apologies for not being very helpful there. Thanks for your time and for the kick-ass package!
