Help required installing LibXML Parser

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

Hello all,

I have to use a XML parser for creating, parsing, validating xml documents. For this i found out that XML::LibXML could be used. I downloaded the latest from CPAN. But i was not able to get this intalled and working.

First I have to install and use this XML module with Rational PERL(CQPERL, RATLPERL) which comes with installation of Clearquest. Hence i cannot use PPM to install the modules. So I have to copy paste the same.

I created a folder called XML under C:\Program Files\Rational\Common\lib\perl5\5.6.1
Then i placed the following files under the XML folder

LibXML.pm
LibXML.pod
NamespaceSupport.pm
SAX.pm
[download]

Where Namespacesupport and SAX are the prerequisites for installing LibXML.

I also downloaded the SAX and Namespacesupport from CPAN and placed under the XML folder

The LibXML folder under XML (C:\Program Files\Rational\Common\lib\perl5\5.6.1\XML\LibXML) contains all the files from the .tar file.

Also I copied the XML::Common module under the XML\LiBXML folder
. Then i copied the common.dll along with the other files: common.pm, common.exp, common.bs, common.lib under C:\Program Files\Rational\Common\lib\perl5\5.6.1\auto\XML\LibXML\Common

i also downlaoded the Libxml2.dll and placed it under C:\Program Files\Rational\Common\lib\perl5\5.6.1\auto\XML\LibXML\Common

Now when i try to create a small perl application

#!/usr/bin/perl
use XML::LibXML;
my $parser = XML::LibXML->new();
[download]

and try to run via CQPERL (cqperl file.pl)
i get an application error with the following message:

AppName: cqperl.exe
AppVer: 5.6.1.629
ModName: common.dll
ModVer: 0.0.0.0
Offset: 0000173d
[download]

and with this CQPERL crashes.

This CQPERL is of PERL version 5.6.1.629

What am i doing wrong here?

Is there any other easy way of installing this LIBXML Parsers?

IT would be very helpful if someone assist me in installing this.

Thanks a ton in advance
Best Regards
Karthik

P.S. More info about CQPERL

There may be a faint hope for you: `Locally applied patches: ActivePerl Build 629 Built under MSWin32 Compiled at Mar 26 2003 18:19:43 ... type:cv -libpath:"\public\ratlperl\5.6.1_AS629\lib\5.6.1\MSWin32-x86- +multi-thre` [download] This suggests to me that your Rational Perl is a rebranded ActiveState Perl (build 629). So you might be able to just download the PPM and copy the files into the appropriate positions, or maybe it even comes with its own PPM. You won't be able to "just" copy some files and copy some random DLLs downloaded from the internet and expect it to magically work. There are ways to use a different toolchain than what was used to compile your Perl to compile extensions, but the preferred and sane way is to use the build environment that was used to build your Perl. In your case, that would be Visual C 6.	[reply] [d/l]

`perl -MCPAN -e shell` And then type `install XML::LibXML` If CPAN is not working for you, you can still download the packages and install them, usually with `perl Makefile.PL make make test make install` [download] Just copying the files won't work, unless the modules are pure perl.

Thanks. But i use CQPERL and i dont think this technique would work :-(	[reply]

Re: Help required installing LibXML Parser by randyk (Parson) on Dec 19, 2007 at 15:52 UTC
One thing you might try is to install the CPAN version of PPM on your machine; to do this, download the PPM-2.1.8.tar.gz source, extract the files, change into the unpacked directory, and run `perl Makefile.PL nmake nmake install` [download] For this, you'll need to install nmake for Windows. After this, you can install XML-LibXML from the uwinnipeg 5.6 repository by issuing the command `ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/XML-LibXML.ppd` [download] This should also install the prerequisite ppm packages, as well as the required `libxml2.dll` library (which goes somewhere in your `PATH`).

OK..now i copied all the required modules like Compress, Archive, XML::Parser from Activestate perl installation. Now i ran the following `U:\.cpan\PPM-2.1.8>cqperl makefile.pl Checking if your kit is complete... Looks good` [download] after his the perl parer crashes with the followging error `AppName: cqperl.exe AppVer: 5.6.1.629 ModName: zlib.dll ModVer: 0.0.0.0 Offset: 000068ec` [download]	[reply] [d/l] [select]

Did you copy the files from an ActivePerl 6xx build? This is what you should be using, as it's based on perl-5.6. And did you copy all the `pm` and `dll` files in the manner described in my earlier reply? This should work assuming the Perl that ships with Rational ClearQuest is compiled with VC++ 6, which is what ActivePerl is compiled with.	[reply]

The error message at the end: Error: Unable to locate installed Perl libraries or Perl source code. It is recommended that you install perl in a standard location before building extensions. Some precompiled versions of perl do not contain these header files, so you cannot build extensions. In such a case, please build and install your perl from a fresh perl distribution. It usually solves this kind of problem. (You get this message, because MakeMaker could not find "\public\ratlp +erl\5.6.1_ AS629\lib\perl5\5.6.1\MSWin32-x86-multi-thread\CORE\perl.h") looks to be most serious - it means you can't build extensions in the standard way because of some missing header files. IBM recommends that you install missing modules manually, which is possible, but as was mentioned in earlier responses, you have to take care where to put the files. In the following, let `$RATIONAL` stand for `C:\Program Files\Rational\Common\lib\perl5\site_perl\5.6.1`. What you could do is grab the sources of the binary ppm packages, extract the files, and then copy them into locations that your Perl expects them. For example, for XML-LibXML-Common, which is a prerequisite, download `XML-LibXML-Common.tar.gz` from http://theoryx5.uwinnipeg.ca/ppmpackages/x86/. When unpacked, the directory structure contains `blib/lib/XML/LibXML/.exists blib/lib/XML/LibXML/Common.pm blib/lib/XML/LibXML blib/arch/auto/XML/LibXML/Common/.exists blib/arch/auto/XML/LibXML/Common/Common.bs blib/arch/auto/XML/LibXML/Common/Common.dll blib/arch/auto/XML/LibXML/Common/Common.exp blib/arch/auto/XML/LibXML/Common/Common.lib blib/arch/auto/XML/LibXML/Common/Common.pdb` [download] Copy the files under `blib/lib/` to `$RATIONAL`, taking care to preserve the subdirectory structure (for example, `blib/lib/XML/LibXML/Common.pm` would go to `$RATIONAL\XML\LibXML\Common.pm`). Then copy the files under `blib/arch/auto/` to `$RATIONAL\MSWin32-x86-multi-thread\auto\`, again taking care to preserve the underlying subdirectory structure. Finally, you'll need the `libxml2.dll` external library; this can be obtained from http://theoryx5.uwinnipeg.ca/ppmpackages/scripts/, and should be placed somewhere under your `PATH` environment variable (type `set PATH` at a command prompt to see what your `PATH` is). You'll then have to repeat this for XML-LibXML, XML-NamespaceSupport, and XML-SAX.	[reply] [d/l]
