Also, the GNAT runtime should not be stripped, as this would break certain features of the debugger that depend on this debugging information (catching Ada exceptions for instance). <p>That step completes the installation of GCC; user level binaries can be found in <samp><var>prefix</var><span class="file">/bin</span></samp> where <var>prefix</var> is the value you specified with the <samp><span class="option">--prefix</span></samp> to configure (or <samp><span class="file">/usr/local</span></samp> by default). (If you specified <samp><span class="option">--bindir</span></samp>, that directory will be used instead; otherwise, if you specified <samp><span class="option">--exec-prefix</span></samp>, <samp><var>exec-prefix</var><span class="file">/bin</span></samp> will be used.) Headers for the C++ and Java libraries are installed in <samp><var>prefix</var><span class="file">/include</span></samp>; libraries in <samp><var>libdir</var></samp> (normally <samp><var>prefix</var><span class="file">/lib</span></samp>); internal parts of the compiler in <samp><var>libdir</var><span class="file">/gcc</span></samp> and <samp><var>libexecdir</var><span class="file">/gcc</span></samp>; documentation in info format in <samp><var>infodir</var></samp> (normally <samp><var>prefix</var><span class="file">/info</span></samp>). <p>When installing cross-compilers, GCC's executables are not only installed into <samp><var>bindir</var></samp>, that is, <samp><var>exec-prefix</var><span class="file">/bin</span></samp>, but additionally into <samp><var>exec-prefix</var><span class="file">/</span><var>target-alias</var><span class="file">/bin</span></samp>, if that directory exists. Typically, such <dfn>tooldirs</dfn> hold target-specific binutils, including assembler and linker. <p>Installation into a temporary staging area or into a <samp><span class="command">chroot</span></samp> jail can be achieved with the command <pre class="smallexample"> make DESTDIR=<var>path-to-rootdir</var> install </pre> <p class="noindent">where <var>path-to-rootdir</var> is the absolute path of a directory relative to which all installation paths will be interpreted. Note that the directory specified by <code>DESTDIR</code> need not exist yet; it will be created if necessary. <p>There is a subtle point with tooldirs and <code>DESTDIR</code>: If you relocate a cross-compiler installation with e.g. ‘<samp><span class="samp">DESTDIR=</span><var>rootdir</var></samp>’, then the directory <samp><var>rootdir</var><span class="file">/</span><var>exec-prefix</var><span class="file">/</span><var>target-alias</var><span class="file">/bin</span></samp> will be filled with duplicated GCC executables only if it already exists, it will not be created otherwise. This is regarded as a feature, not as a bug, because it gives slightly more control to the packagers using the <code>DESTDIR</code> feature. <p>If you are bootstrapping a released version of GCC then please quickly review the build status page for your release, available from <a href="http://gcc.gnu.org/buildstat.html">http://gcc.gnu.org/buildstat.html</a>. If your system is not listed for the version of GCC that you built, send a note to <a href="mailto:gcc@gcc.gnu.org">gcc@gcc.gnu.org</a> indicating that you successfully built and installed GCC. Include the following information: <ul> <li>Output from running <samp><var>srcdir</var><span class="file">/config.guess</span></samp>. Do not send that file itself, just the one-line output from running it. <li>The output of ‘<samp><span class="samp">gcc -v</span></samp>’ for your newly installed <samp><span class="command">gcc</span></samp>. This tells us which version of GCC you built and the options you passed to configure. <li>Whether you enabled all languages or a subset of them. If you used a full distribution then this information is part of the configure options in the output of ‘<samp><span class="samp">gcc -v</span></samp>’, but if you downloaded the “core” compiler plus additional front ends then it isn't apparent which ones you built unless you tell us about it. <li>If the build was for GNU/Linux, also include: <ul> <li>The distribution name and version (e.g., Red Hat 7.1 or Debian 2.2.3); this information should be available from <samp><span class="file">/etc/issue</span></samp>. <li>The version of the Linux kernel, available from ‘<samp><span class="samp">uname --version</span></samp>’ or ‘<samp><span class="samp">uname -a</span></samp>’. <li>The version of glibc you used; for RPM-based systems like Red Hat, Mandrake, and SuSE type ‘<samp><span class="samp">rpm -q glibc</span></samp>’ to get the glibc version, and on systems like Debian and Progeny use ‘<samp><span class="samp">dpkg -l libc6</span></samp>’. </ul> For other systems, you can include similar information if you think it is relevant. <li>Any other information that you think would be useful to people building GCC on the same configuration. The new entry in the build status list will include a link to the archived copy of your message. </ul> <p>We'd also like to know if the <a href="specific.html">host/target specific installation notes</a> didn't include your host/target information or if that information is incomplete or out of date. Send a note to <a href="mailto:gcc@gcc.gnu.org">gcc@gcc.gnu.org</a> detailing how the information should be changed. <p>If you find a bug, please report it following the <a href="../bugs.html">bug reporting guidelines</a>. <p>If you want to print the GCC manuals, do ‘<samp><span class="samp">cd </span><var>objdir</var><span class="samp">; make dvi</span></samp>’. You will need to have <samp><span class="command">texi2dvi</span></samp> (version at least 4.7) and TeX installed. This creates a number of <samp><span class="file">.dvi</span></samp> files in subdirectories of <samp><var>objdir</var></samp>; these may be converted for printing with programs such as <samp><span class="command">dvips</span></samp>. Alternately, by using ‘<samp><span class="samp">make pdf</span></samp>’ in place of ‘<samp><span class="samp">make dvi</span></samp>’, you can create documentation in the form of <samp><span class="file">.pdf</span></samp> files; this requires <samp><span class="command">texi2pdf</span></samp>, which is included with Texinfo version 4.8 and later. You can also <a href="http://www.gnu.org/order/order.html">buy printed manuals from the Free Software Foundation</a>, though such manuals may not be for the most recent version of GCC. <p>If you would like to generate online HTML documentation, do ‘<samp><span class="samp">cd </span><var>objdir</var><span class="samp">; make html</span></samp>’ and HTML will be generated for the gcc manuals in <samp><var>objdir</var><span class="file">/gcc/HTML</span></samp>. <p><hr /> <p><a href="./index.html">Return to the GCC Installation page</a> <!-- ***Binaries**************************************************************** --> <!-- ***Specific**************************************************************** --> <!-- ***Old documentation****************************************************** --> <!-- ***GFDL******************************************************************** --> <!-- *************************************************************************** --> <!-- Part 6 The End of the Document --> </body></html>
