enable native perl UTF8
running xml2-config...failed
The installed version of libxml2 not compatible with XML::LibXML.

You may continue at your own risk, but:

- don't expect XML::LibXML to build or work correctly!
- don't report errors!
- don't send patches!

Check the README file for more information on versions
that are tested with XML::LibXML

Running make test
Make had some problems, maybe interrupted? Won't test
Running make install
Make had some problems, maybe interrupted? Won't install

Go to ftp://ftp.gnome.org/pub/GNOME/sources/libxml2/2.6/ and download
libxml2-2.6.26.tar.gz.

gzcat libxml2-2.6.26.tar.gz | tar xf -
cd libxml2-2.6.26
./configure --prefix=/opt/whatever
make
make check
make install

Now go to your XML::LibXML directory and execute

perl Makefile.PL XMLPREFIX=/opt/whatever

I don't know how to do that kind of config thing in the CPAN shell,
but there's probably a way.

Last time I looked, RedHat used the GNOME desktop by default, and
libxml2 is a core GNOME library. So the library itself is very
likely already be installed, in which case all he needs is the
corresponding -dev package.

OK, not a big Red Hat user myself. I recently had libxml2 issues on a
Solaris 7 machine -- there was a libxml2 on the system, but I was
unwilling to mess with it and so simply installed a new one in my usual
GNU directory.

Anyway, the way to specify config arguments in the CPAN shell is the
"look" command. It will download and unpack the latest tarball, and
open a subshell in the build directory.

Thanks for the tip, I'll try that out.

You've already installed XML::LibXML through RPM. Why are you trying to
install it again?

What happens when you do:

perl -MXML::LibXML -e 'print $XML::LibXML::VERSION, "\n"'

Also, what's the output of "xml2-config --version"? (might be in
/usr/local/bin) 2.6.16 looks like it's supported so either it's not
finding xml2-config (path issue) or that is reporting something other
than what 'make' is expecting.

You appear to be using a non-system perl. That is, you appear to be
using a perl installed in /usr/local, rather than the perl Red Hat
installed in /usr/bin. What do you get from

which perl

? What do you get from

/usr/bin/perl -MXML::LibXML -le'print XML::LibXML->VERSION'

? Have you built perl yourself from source? Why do you have two
installations of perl?

[root@sdgle01 ~]# find / -name LibXML.pm
/usr/local/perl588/lib/site_perl/5.8.8/x86_64-linux/XML/LibXML.pm
/usr/lib64/perl5/vendor_perl/5.8.5/x86_64-linux-thread-multi/XML/LibXML.pm

Should I just copy that file to one of the directories it's looking in?

No, that definitely won't work. Where did those installations of
XML::LibXML come from? I would guess the one in /usr/lib64 is the one
rpm installed; what about the other? Do you have (or have you ever had)
a *third* copy of perl installed, that had /usr/local/perl588/lib in its
@INC?

Also, what's the output of "xml2-config --version"? (might be in
/usr/local/bin) 2.6.16 looks like it's supported so either it's not
finding xml2-config (path issue) or that is reporting something other
than what 'make' is expecting.

[root@sdgle01 ~]# xml2-config --version
2.6.6

Again, rpm reports it has libxml2-2.6.16 installed, but this is
reporting 2.6.6. 2.6.6 is not supported by XML::LibXML 1.62, though it
is supported by XML::LibXML 1.60, so you could try that if you want to
link with this version of libxml2. What do you get from

which xml2-config

? And what from

/usr/bin/xml2-config --version

? Have you installed libxml2 yourself separately from rpm? Again, why do
you (apparently) have two installations of libxml2?
