Minha motivação para esse post foi, um projeto meu antigo que apresentou uns problemas com o Ruby 1.8.7. Alem de já ter ouvido que o Ruby Compilado tem uma performance muito melhor.
Inicialmente, removemos todos os pacotes do gerenciador padrão do ubuntu.

			<content:encoded><![CDATA[<p>Esse post é um tutorial de como compilar o Ruby 1.8.6 ou 1.8.7 no Ubuntu.<br />
Minha motivação para esse post foi, um projeto meu antigo que apresentou uns problemas com o Ruby 1.8.7. Alem de já ter ouvido que o Ruby Compilado tem uma performance muito melhor.</p>
<p>Inicialmente, removemos todos os pacotes do gerenciador padrão do ubuntu.</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> purge ruby ruby1.8 rdoc ri irb libopenssl-ruby ruby-dev libopenssl-ruby1.8 libreadline-ruby1.8 libruby1.8 ruby1.8-dev</pre></div></div>

<p><span id="more-110"></span><br />
Tambem é importante ter os compiladores básicos.</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #660033;">-y</span> <span style="color: #c20cb9; font-weight: bold;">install</span> build-essential libssl-dev libreadline5-dev zlib1g-dev</pre></div></div>

<p>Vamos instalar o checkinstall, para que possamos compilar e gerar um .deb e ter um maior controle sobre o que é instalado</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">aptitude</span> <span style="color: #c20cb9; font-weight: bold;">install</span> checkinstall</pre></div></div>

<p>Agora vamos puxar o código fonte do Ruby</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">wget</span> <span style="color: #c20cb9; font-weight: bold;">ftp</span>:<span style="color: #000000; font-weight: bold;">//</span>ftp.ruby-lang.org<span style="color: #000000; font-weight: bold;">/</span>pub<span style="color: #000000; font-weight: bold;">/</span>ruby<span style="color: #000000; font-weight: bold;">/</span><span style="color: #000000;">1.8</span><span style="color: #000000; font-weight: bold;">/</span>ruby-1.8.6-p287.tar.gz
<span style="color: #c20cb9; font-weight: bold;">tar</span> xvzf ruby-1.8.6-p287.tar.gz
<span style="color: #7a0874; font-weight: bold;">cd</span> ruby-1.8.6-p287</pre></div></div>

<p>Agora vamos seguir para o processo de compilação</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;">.<span style="color: #000000; font-weight: bold;">/</span>configure <span style="color: #660033;">--prefix</span>=<span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span><span style="color: #7a0874; font-weight: bold;">local</span> <span style="color: #660033;">--with-openssl-dir</span>=<span style="color: #000000; font-weight: bold;">/</span>usr <span style="color: #660033;">--with-readline-dir</span>=<span style="color: #000000; font-weight: bold;">/</span>usr <span style="color: #660033;">--with-zlib-dir</span>=<span style="color: #000000; font-weight: bold;">/</span>usr
<span style="color: #c20cb9; font-weight: bold;">make</span>
<span style="color: #c20cb9; font-weight: bold;">sudo</span> checkinstall</pre></div></div>

<p>Para testar se tudo ficou ok:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>local<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #660033;">-ropenssl</span> <span style="color: #660033;">-rzlib</span> <span style="color: #660033;">-rreadline</span> <span style="color: #660033;">-e</span> <span style="color: #ff0000;">&quot;puts :success&quot;</span></pre></div></div>

<p>Criando os links simbólicos</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">ln</span> <span style="color: #660033;">-s</span> <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>local<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby</pre></div></div>

<p>Um problema que eu tive, foi com a instalação anterior do RubyGem, que apresentava o seguinte erro:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"> gem <span style="color: #660033;">-v</span>
<span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>gem:<span style="color: #000000;">8</span>:<span style="color: #000000; font-weight: bold;">in</span> <span style="color: #000000; font-weight: bold;">`</span>require<span style="color: #ff0000;">': no such file to load -- rubygems (LoadError)
	from /usr/bin/gem:8</span></pre></div></div>

<p>Isso aconteceu, pois a instalação do Ruby e dos Gems mudaram de local.<br />
Para resolver, re-instalamos o gem na nova pasta do Ruby.</p>
<p>A pasta anterior do Ruby era:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">whereis</span> ruby
ruby: <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby1.8 <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>share<span style="color: #000000; font-weight: bold;">/</span>man<span style="color: #000000; font-weight: bold;">/</span>man1<span style="color: #000000; font-weight: bold;">/</span>ruby.1.gz</pre></div></div>

<p>E agora mudou para:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">whereis</span> ruby
ruby: <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby1.8 <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>local<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>ruby <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>local<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>ruby</pre></div></div>

<p>Isso aconteceu, pois mudamos o diretório de instalação de &#8220;/usr/&#8221; para &#8220;/usr/local/&#8221; no momento do configure (configure &#8211;prefix=/usr/local)</p>
<p>Para re-instalar o gem:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">wget</span> http:<span style="color: #000000; font-weight: bold;">//</span>rubyforge.org<span style="color: #000000; font-weight: bold;">/</span>frs<span style="color: #000000; font-weight: bold;">/</span>download.php<span style="color: #000000; font-weight: bold;">/</span><span style="color: #000000;">45905</span><span style="color: #000000; font-weight: bold;">/</span>rubygems-1.3.1.tgz
<span style="color: #c20cb9; font-weight: bold;">tar</span> xvzf rubygems-1.3.1.tgz
<span style="color: #7a0874; font-weight: bold;">cd</span> rubygems-1.3.1<span style="color: #000000; font-weight: bold;">/</span>
<span style="color: #c20cb9; font-weight: bold;">sudo</span> ruby setup.rb
&nbsp;
gem1.8 <span style="color: #660033;">-v</span>
1.3.1</pre></div></div>

<p>O gem tambem mudou do lugar:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">whereis</span> gem
gem: <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>gem <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>gem1.8</pre></div></div>

<p>Para:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">whereis</span> gem
gem: <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>gem1.8 <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>gem <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>local<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span>gem</pre></div></div>

<p>Com a mudança de diretório do gem, perdemos todas as gems que haviam instaladas.<br />
As gems anteriores, podem ser listadas com o seguinte comando:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">ls</span> <span style="color: #000000; font-weight: bold;">/</span>usr<span style="color: #000000; font-weight: bold;">/</span>lib<span style="color: #000000; font-weight: bold;">/</span>ruby<span style="color: #000000; font-weight: bold;">/</span>gems<span style="color: #000000; font-weight: bold;">/</span><span style="color: #000000;">1.8</span><span style="color: #000000; font-weight: bold;">/</span>gems<span style="color: #000000; font-weight: bold;">/</span></pre></div></div>

<p>Aprendi boa parte disso nos seguintes sites:</p>

			<content:encoded><![CDATA[<p>Assim que criei meu tutorial de instalação do Ruby e Rails no Ubuntu Intrepid Ibex (8.10), o <a href="http://www.tatri.com.br/">Guilherme</a> fez<a href="http://www.gustavocaixeta.com/2008/11/instalando-ruby-e-rails-no-ubuntu-810-intrepid-ibex/comment-page-1/#comment-17"> um comentário</a> sobre <a href="http://www.rubyonrails.org/down">os problemas que haviam do Ruby 1.8.7</a> no Ubuntu 8.10 em relação a versões antigas do Rails (anteriores ao 2.1).</p>
<p>Mas parece que mudaram a página do Rails <img src='http://www.gustavocaixeta.com/wp-includes/images/smilies/icon_razz.gif' alt=':P' class='wp-smiley' />  falando que o 1.8.7 já funciona perfeitamente ehehe.<br />
<span id="more-99"></span><br />
Um exemplo clássico disso, era uns problemas com meu primeiro projeto em Rails (O lamina foi feito no Rails 1.2.6).</p>
<p>Basicamente o procedimento é o seguinte:</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">cp</span> <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>apt<span style="color: #000000; font-weight: bold;">/</span>sources.list <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>apt<span style="color: #000000; font-weight: bold;">/</span>sources.list_backup</pre></div></div>

<p>Depois iremos criar o arquivo /etc/apt/preferences</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">touch</span> <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>apt<span style="color: #000000; font-weight: bold;">/</span>preferences
<span style="color: #c20cb9; font-weight: bold;">sudo</span> gedit <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>apt<span style="color: #000000; font-weight: bold;">/</span>preferences</pre></div></div>

<p>E insira o seguinte conteudo nele:</p>

<div class="wp_syntax"><div class="code"><pre class="text" style="font-family:monospace;">Package: ruby

<p>Agore iremos criar uma cópia das fontes, porem substituindo &#8220;intrepid&#8221; por &#8220;hardy&#8221;</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> gedit <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>apt<span style="color: #000000; font-weight: bold;">/</span>sources.list</pre></div></div>

<p>Depois de Inserir uma cópia das fontes do hardy no seu arquivo sources.list</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> update</pre></div></div>

<p>Para pegar a lista de pacotes disponivel para o hardy.</p>
<p>Depois disso, iremos remover o Ruby.</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> remove ruby ruby1.8 rdoc ri irb libopenssl-ruby ruby-dev libopenssl-ruby1.8 libreadline-ruby1.8 libruby1.8 ruby1.8-dev</pre></div></div>

<p>E depois re-instalar ele</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> ruby ruby1.8 rdoc ri irb libopenssl-ruby ruby-dev <span style="color: #660033;">-V</span></pre></div></div>

<p>Agora o resultado da versão do Ruby deve mudar</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;">gustavo<span style="color: #000000; font-weight: bold;">@</span>gustavo-mv:~$ ruby <span style="color: #660033;">-v</span>

&nbsp;
gustavo<span style="color: #000000; font-weight: bold;">@</span>gustavo-mv:~$ ruby <span style="color: #660033;">-v</span>

<p>Acho que isso já deixa tudo 100%. Tenho só umas duvidas em relação aos Ruby Gems já instalados.</p>
