Building libxml-ruby gem on Ubuntu Hardy

Shane — Mon, 14 Jul 2008 17:07:39 +0000

I had been having a lot of trouble using libxml-ruby on Ubuntu Hardy for a hobby project of mine. Any task including libxml calls via require 'xml/libxml' fails with the message:

no such file to load -- libxml_so

To solve this:

sudo apt-get install libxml2 libxml2-dev
cd /usr/lib/ruby/gems/1.8/gems/libxml-ruby-0.7.0
sudo ruby ext/libxml/extconf.rb
sudo make; sudo make install

MySQL ruby gem with MacPorts MySQL

sudo env ARCHFLAGS="-arch i386" gem install mysql -- --with-mysql-include=/opt/local/include/mysql5 --with-mysql-lib=/opt/local/lib/mysql5 --with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config

This worked for me with mysql installed via macports by the command:

sudo port install mysql5 +server

Memcached and memcached gem on Leopard

In the pursuit of utilizing memcached on my 2008 MacBook with Leopard, I’ve been stuck for a while trying to get the memcached gem to compile and install properly using memcached installed through MacPorts.

After stumbling upon the proper procedure at the Peleteiro blog, I finally noticed that it’s actually in the memcached gem docs.

Anyhow, here’s the proper procedure for installing memcached and the gem on Leopard:

sudo port install memcached libmemcached
sudo env ARCHFLAGS="-arch i386" gem install memcached -- --with-rlibmemcached-include=/opt/local/include --with-rlibmemcached-lib=/opt/local/lib

I might later look into trying interlock or cache_fu, or following some/all of these direction.
