    <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>

    &lfs74_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>

      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

    <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>

  <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>

    <para>If you have installed additional packages such as valgrind and gdb,
    the gcc part of the testsuite will run more tests than in LFS. 
    Some of those will report FAIL and others XPASS (pass when expected
    to FAIL).  To run the checks:</para>

ln -v -sf gcc /usr/bin/cc     &amp;&amp;

chown -v -R root:root \

<!-- Not needed since we do not install libffi
    <para>The <filename class='libraryfile'>libffi</filename> interface header
    is installed in a location where other packages will not be able to find
    it. If you included Java as one of the installed languages, create a

    remedy this:</para>

<screen role="root"><userinput>ln -v -sf `find /usr/lib/gcc -name ffitarget.h` /usr/include</userinput></screen>-->

    <para>You should now remove the <application>GNAT</application>
    installation and perform other cleanups:</para>

export PATH=$PATH_HOLD &amp;&amp;
unset PATH_HOLD</userinput></screen>

    <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

    <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
