Syndication-NewsML module problem

cormanaz has asked for the wisdom of the Perl Monks concerning the following question:

Good day monks. I have installed mod Syndication::NewsML. When I try to use it I get the following error:

Can't locate NewsML/Node.pm in @INC (@INC contains: C:/Perl/lib C:/Perl/site/lib .) at C:/Perl/site/lib/Syndication/NewsML.pm line 9. BEGIN failed--compilation aborted at C:/Perl/site/lib/Syndication/NewsML.pm line 9. Compilation failed in require at C:\projects\sources\reuters\newsmltest.pl line 1. BEGIN failed--compilation aborted at C:\projects\sources\reuters\newsmltest.pl line 1.

And line 9 of NewsML.pm contains the use statement for the offending module. Is there a simple way to fix this problem, like modifying the @INC variable?

thanks...steve

A little more detail would be good. Where did you install Syndication::NewsML? Is it (and any binaries below it) somewhere in `@INC`? Did you compile perl yourself, or is an ActiveState distro? I ask because if you have ActiveState, using PPM would've fixed this, so I'm curious if/why you didn't use it. The bottom line is that's probably an installation issue. It's quite likely that you can fix this with an appropriate `use lib` statement, but it's hard to say with so little info. Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.	[reply] [d/l] [select]

It is an ActiveState distro, and I installed with PPM (actually Komodo Visual Package Manager). This is why I'm confused by the error. As indicated by the error message I posted, it's installed in C:/Perl/site/lib/Syndication/. In this directory is NewsML.pm, and then there is a subdir called NewsML that contains all the associated modules, including the one complained-about in the error message. The error message also says "(@INC contains: C:/Perl/lib C:/Perl/site/lib .)" I'm not up on all the details of module construction so I don't know if Syndication and Syndication/NewsML have to be in there explicitly or not. I also don't know what that dot in the list means.

Hm. The problem appears to be in the library itself. It's not including its own prefix for the sub-modules. In other words, it's doing: `use NewsML::Node; use NewsML::IdNode; use NewsML::AssignmentNode; # and so on` [download] instead of `use Syndication::NewsML::Node; use Syndication::NewsML::IdNode; use Syndication::NewsML::AssignmentNode;` [download] Probably the easiest fix is to add a `use lib` statement at the top of your program, like so: `use lib "C:/Perl/site/lib/Syndication"; use Syndication::NewsML;` [download] And then it'll find the other modules. It may be worth filing a bug report via CPAN RT, even though it appears the author hasn't worked on it since 2002. Do not rebuke them with harsh words ... but rather lead them gently - with URLs - so that they may learn wisdom.	[reply] [d/l] [select]
