82<p>The latest version of this document is always available at
83<a href="http://gcc.gnu.org/install/">http://gcc.gnu.org/install/</a>.
84It refers to the current development sources, instructions for
85specific released versions are included with the sources.
86</p>
87<p>This document describes the generic installation procedure for GCC as well
88as detailing some target specific installation instructions.
89</p>
90<p>GCC includes several components that previously were separate distributions
91with their own installation instructions.  This document supersedes all
92package-specific installation instructions.
93</p>
94<p><em>Before</em> starting the build/install procedure please check the
95<a href="specific.html">host/target specific installation notes</a>.
96We recommend you browse the entire generic installation instructions before
97you proceed.
98</p>
99<p>Lists of successful builds for released versions of GCC are
100available at <a href="http://gcc.gnu.org/buildstat.html">http://gcc.gnu.org/buildstat.html</a>.
101These lists are updated as new information becomes available.
102</p>
103<p>The installation procedure itself is broken into five steps.
104</p>
105<ol>
106<li> <a href="prerequisites.html">Prerequisites</a>
107</li><li> <a href="download.html">Downloading the source</a>
108</li><li> <a href="configure.html">Configuration</a>
109</li><li> <a href="build.html">Building</a>
110</li><li> <a href="test.html">Testing</a> (optional)
111</li><li> <a href="finalinstall.html">Final install</a>
112</li></ol>
113
114<p>Please note that GCC does not support &lsquo;<samp>make uninstall</samp>&rsquo; and probably
115won&rsquo;t do so in the near future as this would open a can of worms.  Instead,
116we suggest that you install GCC into a directory of its own and simply
117remove that directory when you do not need that specific version of GCC
118any longer, and, if shared libraries are installed there as well, no
119more binaries exist that use them.
120</p>
121<p>There are also some <a href="old.html">old installation instructions</a>,
122which are mostly obsolete but still contain some information which has
123not yet been merged into the main part of this manual.
