This document supersedes all 53package specific installation instructions. 54 55 <p><em>Before</em> starting the build/install procedure please check the 56<a href="specific.html">host/target specific installation notes</a>. 57We recommend you browse the entire generic installation instructions before 58you proceed. 59 60 <p>Lists of successful builds for released versions of GCC are 61available at <a href="http://gcc.gnu.org/buildstat.html">http://gcc.gnu.org/buildstat.html</a>. 62These lists are updated as new information becomes available. 63 64 <p>The installation procedure itself is broken into five steps. 65 66 <ol type=1 start=1> 67<li><a href="prerequisites.html">Prerequisites</a> 68<li><a href="download.html">Downloading the source</a> 69<li><a href="configure.html">Configuration</a> 70<li><a href="build.html">Building</a> 71<li><a href="test.html">Testing</a> (optional) 72<li><a href="finalinstall.html">Final install</a> 73 </ol> 74 75 <p>Please note that GCC does not support ‘<samp><span class="samp">make uninstall</span></samp>’ and probably 76won't do so in the near future as this would open a can of worms.
