How do I install XML::Xerces?

Question

Please see Part 2 which list latest errors while installing module continued post.

Normally when I try to install XML::Xerces CPAN module using standard cpan> install XML::Xercers than I get following error message after some processing:

XML-Xerces-2.7.0-0/samples/SEnumVal.pl
...
XML-Xerces-2.7.0-0/postSource.pl
XML-Xerces-2.7.0-0/xerces-headers.txt
Removing previously used /home/adoshi/.cpan/build/XML-Xerces-2.7.0-0

  CPAN.pm: Going to build J/JA/JASONS/XML-Xerces-2.7.0-0.tar.gz


   WARNING

You have not defined any of the following environment variables:
   XERCESCROOT
   XERCES_LIB
   XERCES_INCLUDE

These instruct me how to locate the Xerces header files, and the
Xerces dynamic library. If they are installed in a standard system
directory, I will located them without those variables.

However, if they have been installed in a non-standard location
(e.g. '/usr/include/xerces'), then I will need help. See the README
for more info.

build the C++ glue files that come with Xerces.pm.

Proceeding anyway ...

After Setting Enviornment Variables to /home/username/XML-Xerces-2.7.0-0/XML-Xerces-2.7.0-0/Xerces.pm, note here am not sure whether I should point my environment variable to Xerces.pm or Xerces.cpp or Xerces-extra.pm or Xerces.i, but for now am pointing environment variables to /home/username/XML-Xerces-2.7.0-0/XML-Xerces-2.7.0-0/Xerces.pm

After setting environment variables as mentioned and entering cpan>install XML::Xerces I get following message:

Note: I have tried downloading XML::Xerces and trying to again install it, both manually as well as using CPAN but am getting above mentioned error message.

What can be the possible reason and what can be suggested turn around to take care of this issue ?

Update: Even after building Xerces-C, XML::Xerces module is not building and am getting following error message.

You are attempt to build XML::Xerces-2.7.0-0 using Xerces-C-2.8.0,
this will most likely fail, so I am aborting.

You must use Xerces-C-2.7.0

Answer 1

Here's a general rule: any environment variable that is named something like "ROOT" is asking for a directory, not a file.

However, it does not appear that you have installed the Xerces library, which is necessary before you install the perl module. I'll quote some portions of the output you provided, as the hint you missed as to what to do next:

---

"...These instruct me how to locate the Xerces header files, and the Xerces dynamic library..."

"Without these I cannot find the config.status file that was used to build your Xerces-C library"

---

So, did you install Xerces-C? You'll have much better results installing the Perl module after that.

Answer 2

Did you try using the PPM to install XML::Xerces?
