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. Instead, 77we suggest that you install GCC into a directory of its own and simply 78remove that directory when you do not need that specific version of GCC 79any longer, and, if shared libraries are installed there as well, no 80more binaries exist that use them. 81 82 <p>There are also some <a href="old.html">old installation instructions</a>, 83which are mostly obsolete but still contain some information which has 84not yet been merged into the main part of this manual. 85 86 <p><hr /> 87<p><a href="./index.html">Return to the GCC Installation page</a> 88 89 <p>Copyright © 1988-2015 Free Software Foundation, Inc. 90 <pre class="sp"> 91 92</pre> 93Permission is granted to copy, distribute and/or modify this document 94under the terms of the GNU Free Documentation License, Version 1.3 or 95any later version published by the Free Software Foundation; with no 96Invariant Sections, the Front-Cover texts being (a) (see below), and 97with the Back-Cover Texts being (b) (see below).
