Re: OAI::Harvester installation help
I am attempting to use some code which depends on Net::OAI::Harvester, but my attempts to install OAI::Harvester are running into problems with: Any suggestions for getting this installed properly? I'm assuming that this is a case where a simple force install isn't going to get me a working installation... I've used Net::OAI::Harvester on both Ubuntu and Windows XP for my projects. On XP I've used Strawberry Perl, in which installing using CPAN luckily worked without any problem. In Ubuntu, I had to install from synaptic when CPAN failed. If I remember correctly, the command was: # sudo apt-get install libnet-oai-harvester-perl It works better than cpan in managing dependencies in my experience. Regards, Saiful Amin
RE: OAI::Harvester installation help
Thanks for the responses! I was also contacted off-list by Net::OAI::Harvester's maintainer and we tracked the issue down to a rogue standalone release of XML::SAX::Base. Removing that, so that the XML::SAX::Base included with XML::SAX was used instead, resolved my problems and I was then able to install Net::OAI::Harvester cleanly. I am not so familiar with the oai harvesting tools in Perl, so forgive me if I am giving you incorrect information. My vague recollection is that there are several oai harvesters for Perl. There are, but the import tool I'm using is specifically built to use Net::OAI::Harvester. In Ubuntu, I had to install from synaptic when CPAN failed. If I remember correctly, the command was: # sudo apt-get install libnet-oai-harvester-perl It works better than cpan in managing dependencies in my experience. Although my dev laptop is Ubuntu, the servers I deploy to tend to be running Very Old Releases of Fedora, so I try to stay within CPAN despite its warts, simply for the sake of broad compatibility. The security of running installation tests is a great bonus, too, though - in this particular case, I expect that installing Ubuntu's packaged version would have gotten me a non-working installation because the rogue XML::SAX::Base would still be there, it just wouldn't have been caught during installation.
Re: OAI::Harvester installation help
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello, thanks to further input from the original reporter I (as co-maintainer of N:O:H) have been able to sort out the issues illustrated by the report: - - one of the repositories used in the test suite changed its address recently thus causing some tests to fail: fixed - - The LibXML family of parsers behaves very noisily when it comes to the test for illegal XML making it hard to notice that the test actually succeeds (not fixed) Two issues with XML::SAX might be of broader interest: [not applicable to this thread: - - ParserDetails.ini XML::SAX (::ParserFactory) uses a text file ParserDetails.ini located in the folder SAX.pm resides in or (Debian only?) under /etc/perl/... This file contains the list of known parsers in this installation and their properties. For myself I have noticed several times that this file was not generated (because of non-interactive dependency installs?) and subsequently installed individual parsers were not registered. My impression is that the XML::SAX framework should fall back to XML::SAX::PurePerl installed by the package itself but this does not seem to happen in the Net::OAI::Harvester test suite (maybe because the parser is requested with a required feature). Status: not tackled yet cf. http://perl-xml.sourceforge.net/faq/#parserdetails.ini ] - - latest version of XML::SAX::Base some sub-modules of Net::OAI::Harvester use the get_handler() method supplied by XML::SAX::Base as of version 1.04. This module is literally hidden in the XML::SAX distribution (source is generated by Makefile.PL to prevent indexing of the module on CPAN). There is a strain of standalone versions of XML::SAX::Base on CPAN ending at version 1.02 which does not contain the method in question. (The README of this standalone module gives the warning that you probably do not want to install this module but the complete XML::SAX framework). When you explicitly request installation of XML::SAX::Base there is a probability that this fetches version 1.02 and takes precedence over or actually overwrites version 1.04 installed by XML::SAX and there is absolutely no upgrade path: XML::SAX::Base 1.02 must be uninstalled/removed then for things to work again. For Net::OAI::Harvester I have refined the requirement of XML::SAX::Base to the specific version 1.04 and I'm awaiting the CPAN Tester reports to come in: It might well be that more systems than before are entrapped to install the wrong module when performing Build installdeps and thus effectively cut themselves off from executing the tests at all.

RE: marcdump hex switch
I never got an answer to this back in 2008 and thought I might have better luck now... -- Michael -Original Message- From: Doran, Michael D Sent: Thursday, February 21, 2008 11:03 AM To: perl4lib@perl.org Subject: marcdump hex switch I have MARC::Record 2.0 installed [1]. According to the Changes file marcdump now has a --hex switch [2]: [ENHANCEMENTS] - Added --hex switch to marcdump, which dumps the record in hexadecimal. The offsets are in decimal so that you can match them up to values in the leader. The offset is reset to 0 when we're past the directory so that you can match up the data with the offsets in the directory. However I'm *not* finding that my marcdump actually has that hex switch: /usr/local/scripts/xml/marc = marcdump --hex test.mrc Unknown option: hex Usage: marcdump [options] file(s) Options: --[no]print Print a MicroLIF-style dump of each record --lif Input files are MicroLIF, not USMARC --field=specSpecify a field spec to include. There may be many. Examples: --field=245 --field=1XX --[no]quiet Print status messages --[no]stats Print a statistical summary by file at the end --version Print version information --help Print this summary I poked around the marcdump script and didn't find anything hex: my $opt_print = 1; my $opt_quiet = 0; my $opt_stats = 1; my @opt_field = (); my $opt_help = 0; my $opt_lif = 0; Any ideas/explanations?
