title: Installation of Qt 4.8.7 in Ubuntu 18.04.1 LTS
body: <p>I am trying to install Qt 4.8.7 from source (<a href="https://download.qt.io/archive/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz" rel="nofollow noreferrer">https://download.qt.io/archive/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz</a>) in a virtual machine running Ubuntu 18.04.1 LTS</p>

  <p>So the commands I follow are:</p>
  
  <pre><code>mkdir Qt
  cd Qt
  wget https://download.qt.io/archive/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz
  tar -xzf qt-everywhere-opensource-src-4.8.7.tar.gz
  mv qt-everywhere-opensource-src-4.8.7 Qt-Source
  cd Qt-Source
  ./configure
  </code></pre>
  
  <p>Then I choose the Open Source Edition, accept the terms of License. After that it displays:</p>
  
  <pre><code>Qt is now configured for building. Just run 'make'.
  Once everything is built, you must run 'make install'.
  Qt will be installed into /usr/local/Trolltech/Qt-4.8.7
  
  </code></pre>
  
  <p>So ...</p>
  
  <pre><code>make 
  </code></pre>
  
  <p>and I have the next error;</p>

  <p>Another thing is that in the process of running make, there are a lot of errors like these:</p>

  <p>Could you help me? Please</p>
