Can't install nokogiri 1.6.6.2 on debian wheezy

[Emmanuel Décarie]

Hello,

I can't find a way to install nokogiri 1.6.6.2 which is part of the CoRM package, an open source CRM (http://www.corm.fr/) on my Debian Wheezy server.

<pre>

Distributor ID: Debian
Description: Debian GNU/Linux 7.7 (wheezy)
Release: 7.7
Codename: wheezy

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

</pre>

Here's part of the error message:

<pre>

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/usr/bin/ruby1.9.1 extconf.rb --use-system-libraries

checking if the C compiler accepts ... yes

Building nokogiri using system libraries.

libxml2 version 2.6.21 or later is required!

*** extconf.rb failed ***

Could not create Makefile due to some reason, probably lack of

necessary libraries and/or headers.  Check the mkmf.log file for more

details.  You may need configuration options.

</pre>

This is odd because it seems that I have every packages needed for libxml2:

<pre>

dpkg -l|grep libxml

</pre>

Also, I have already installed what's look like  an old version of the libnokogiri the and ruby-nokogiri lib installed.

<pre>

dpkg -l |grep nokogiri
ii  libnokogiri-ruby1.9.1              1.5.5-1                       all          Transitional package for ruby-nokogiri

</pre>

Here's the output of the mkmf.log:

</pre>

It's like libxml2 is too old when it's newer than the requirement (as far as I can understand).

I'm not sure how to proceed from here.

Btw, I tried the tips provided on this page with no success:

The gem is installed with `--use-system-libraries` enabled, but the system libxml2 library is too old. You can however use the bundled libxml2 file, if you remove `--use-system-libraries` .

I did a quick test on debian 7.7:

``` sh

$ docker run -it --rm debian:7.7

root@ff2f4dccacab:/# cat /etc/os-release | grep NAME

PRETTY_NAME="Debian GNU/Linux 7 (wheezy)"

NAME="Debian GNU/Linux"

root@ff2f4dccacab:/# apt-get update && apt-get install ruby-dev zlib1g-dev patch make

[...]

root@ff2f4dccacab:/# gem inst nokogiri

Building native extensions.  This could take a while...

Hello Lars,

Thanks for your answer.

Although I didn't get from irb the right version, I was able to install the CoRM bundle.

Thanks!
