    <title>Introduction to GCC</title>

    <para>The <application>GCC</application> package contains GNU compilers.
    This package is useful for compiling programs written in C, C++, Fortran,
    Java, Objective C, Objective C++, Ada, and Go. You should ensure you
    actually need one of these additional compilers (C and C++ are installed
    in LFS) before you install them. Additionally, there are instructions in
    the BLFS book to install <xref linkend="openjdk"/>, which can be used
    instead of the Java provided by the <application>GCC</application> package.
    Many consider the Iced Tea version to be a more robust Java environment
    than the one provided by <application>GCC</application>.</para>

    &lfs73_checked;

    <caution>
      <para>If you are upgrading <application>GCC</application> from any other
      version prior to &gcc-version;, then you must be careful compiling 3rd
      party kernel modules. You should ensure that the kernel and all its
      native modules are also compiled using the same version of
      <application>GCC</application> that you use to build the 3rd party module.
      This issue does not affect native kernel (and kernel modules) updates,
      as the instructions below are a complete reinstallation of
      <application>GCC</application>. If you have existing 3rd party modules
      installed, ensure they are recompiled using the updated version of
      <application>GCC</application>. As always, never update the kernel
      headers from the ones used when <application>Glibc</application> was
      compiled during LFS.</para>

    <note>
      <para>If you plan to compile Ada, you will need to install

      dependency when you recompile <application>GCC</application>
      to include Ada. At the AdaCore download page, choose your platform and
      2013, then select the file to download. You probably want the x86-linux
      or x86_64-linux file.</para>

    <title>Installation of GNAT</title>

    <para>Before unpacking and changing into the GCC source directory, first
    unpack the <application>GNAT</application> tarball.  You may have to drill
    down several levels and unpack a second tarball.  For example,
    AdaCore-Download-2013-07-22_0530.tar expands to
    <filename>x86_64-linux/2013/gnatgpl/gnat-gpl-2013-x86_64-pc-linux-gnu-bin.tar.gz</filename>.
    Expand this second tarball and change into the newly created directory.
    Install <application>GNAT</application> by running the following
    command:</para>

<screen><userinput>make ins-all prefix=/opt/gnat</userinput></screen>

    <para>The <application>GNAT</application> compiler can be invoked by
    executing the <command>gcc</command> binary installed in <filename
    class='directory'>/opt/gnat/bin</filename>.</para>

    <para>You may now remove the <application>GNAT</application>
    source directory if desired.</para>

    <para>Prepare to compile <application>GCC</application> by placing the
    <application>GNAT</application> version of <command>gcc</command> at the
    beginning of the <envar>PATH</envar> variable by using the following
    commands as the <systemitem class="username">root</systemitem> user:</para>

<screen><userinput>PATH_HOLD=$PATH &amp;&amp;
export PATH=/opt/gnat/bin:$PATH_HOLD</userinput></screen>

    <para>Doing so has the drawback that the <application>GCC</application>
    and <application>Binutils</application> executables are taken
    from the just installed <application>GNAT</application> package, but the
    versions of those executables are outdated compared to those installed in
    LFS. This is not important for the <application>GCC</application> compilers,
    since they recompile themselves during the bootstrap process. On the other
    hand, the outdated <command>ld</command> and <command>as</command> tools
    are used all along. In order to use the LFS tools, issue:</para>

<screen><userinput>find /opt/gnat -name ld -exec mv -v {} {}.old \;
find /opt/gnat -name as -exec mv -v {} {}.old \;</userinput></screen>

  <sect2 role="installation">
    <title>Installation of GCC</title>

    <para>Install <application>GCC</application> by running the
    following commands:</para>

    <important>

      <para>The installation process may overwrite your existing
      <application>GCC</application> <command>gcc</command> and
      <command>c++</command> compilers and libraries. Having the
      <application>Tcl</application>, <application>Expect</application> and
      <application>DejaGnu</application> packages installed before beginning
      the build is highly recommended so you can run the full suite of
      tests.</para>

      <para>Do not continue with the <command>make install</command> command
      until you are confident the build was successful. You can compare your
      test results with those found at <ulink
      url="http://gcc.gnu.org/ml/gcc-testresults/"/>.  You may also want to
      refer to the information found in the <application>GCC</application>
      section of Chapter 6 in the LFS book (<ulink
      url="&lfs-root;/chapter06/gcc.html"/>).</para>

    </important>

    <para>The instructions below let the build machinery perform a
    <quote>bootstrap</quote> intentionally. This is necessary if you
    install the <application>Ada</application> compiler anyway. Even
    if you don't, a bootstrap is recommended for robustness.</para>

    <title>Command Explanations</title>

    <para>The first two <command>sed</command> commands prevent the
    installation of the <application>libffi</application> library bundled
    with <application>GCC</application>, since it is outdated compared to
    <xref linkend="libffi"/>. The three other <command>sed</command> commands
    are the same ones used during the build of LFS.</para>

    <para><command>mkdir ../gcc-build; cd ../gcc-build</command>: The
    <application>GCC</application> documentation recommends
    building the package in a dedicated build directory.</para>

    <para><parameter>--enable-shared --enable-threads=posix
    --enable-__cxa_atexit</parameter>: These parameters are required to build
    the <application>C++</application> libraries to published standards.</para>

    <para><parameter>--disable-multilib</parameter>: This parameter ensures
    that files are created for the specific architecture of your computer.</para>

<!-- Double dashes are forbidden in comments, so use "- -". Change it to
     double dash if you ever remove this comment!
    <para><parameter>- -enable-bootstrap</parameter>: This parameter is used
    so that a bootstrap installation is performed.</para>
-->
    <para><parameter>--enable-clocale=gnu</parameter>: This parameter is a
    failsafe for incomplete locale data.</para>

    <para><parameter>--enable-lto</parameter>: Setting this parameter allows
    to build a compiler which is able to perform <quote>link time
    optimization (lto)</quote>.</para>

    <para>
    <parameter>--enable-languages=c,c++,fortran,java,objc,obj-c++,ada,go</parameter>:
    This command identifies which languages to build. You may modify
    this command to remove undesired languages.</para>

    <para><command>ulimit -s 32768</command>: This command prevents several
    tests from running out of stack space.</para>

    <para><command>make -k check</command>: This command runs the test suite
    without stopping if any errors are encountered.</para>

    <para><command>../gcc-&gcc-version;/contrib/test_summary</command>: This
    command will produce a summary of the test suite results. You can append
    <command>| grep -A7 Summ</command> to the command to produce an even more
    condensed version of the summary. You may also wish to redirect the output
    to a file for review and comparison later on.</para>

    <para><command>ln -v -sf ../usr/bin/cpp /lib</command>: This command
    creates a link to the C PreProcessor as some packages expect it to be
    installed in the <filename class='directory'>/lib</filename>
    directory.</para>

    <para><command>ln -v -sf gcc /usr/bin/cc</command>: This link is created as
    some packages refer to the C compiler using an alternate name.</para>

    <para><command>chown -v -R root:root
    /usr/lib/gcc/*linux-gnu/...</command>:
    If the package is built by a user other than root, the ownership of the
    installed <filename class='directory'>include</filename> and
    <filename class='directory'>adalib</filename> directories (and their
    contents) will be incorrect. These commands change the ownership to the
    <systemitem class="username">root</systemitem> user and group . Omit the
    command changing the Ada directories if you did not include Ada as one of
    the installed languages.</para>
