How can I install XML::LibXML on Ubuntu

Here is the stdout for install:

$sudo cpanm XML::LibXML
--> Working on XML::LibXML
Fetching http://www.cpan.org/authors/id/S/SH/SHLOMIF/XML-LibXML-2.0014.tar.gz ... OK

If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.

Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.

i tried installing libxml2 manually, but still getting the same issue.

also, i checked for libxml2-dev:

 sudo apt-get install libxml2-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libxml2-dev is already the newest version.

here is the system info:

I think the relevant line is:

Checking for ability to link against libxml2...libxml2, zlib, and/or the Math library (-lm) have not been found.

So, you've covered off libxml. Have you installed the appropriate zlib package? Try:

sudo apt-get install zlib1g-dev

Then try installing XML::LibXML again.


Why do you want to use CPAN for this anyway? It is typically very bad idea to install CPAN packages if you have native packages provided by standard operating system installer.

Ubuntu provides a lot of Perl packages natively, with following naming convention: package name always starts with lib, then Perl package name like XML::LibXML is converted to lower case and :: replaced to dash - (XML::LibXML => xml-libxml), and finally -perl suffix is added. In other words, native package name for XML::LibXML would be libxml-libxml-perl.

So, in your case, you simply run this command and it will pull all necessary dependencies automatically:

sudo apt-get install libxml-libxml-perl

If you don't like this package for any reason you can uninstall it with sudo apt-get remove. If you use CPAN, it is very difficult to uninstall it reliably.


Overlooked the obvious:

sudo apt-get install --reinstall zlibc zlib1g zlib1g-dev

then:

sudo cpanm XML::LibXML

works!


Maybe this is new version. I did:

sudo apt-get install libxml2-dev

After this module builded and installed successfully
