<title>Re-installation of GCC</title>

<para>Check if there is PTYs for the test suites:</para>

<screen><userinput>expect -c "spawn ls"</userinput></screen>

<para>Apply two patches:</para>

<screen><userinput>patch -Np1 -i ../gcc-&gcc-version;-no_fixincludes-1.patch
patch -Np1 -i ../gcc-&gcc-version;-specs-2.patch</userinput></screen>

<para>Create a separate build directory again:</para>

<screen><userinput>mkdir ../gcc-build
cd ../gcc-build</userinput></screen>

<para>Now prepare GCC for compilation:</para>

<screen><userinput>../gcc-&gcc-version;/configure --prefix=/tools \
    --libexecdir=/tools/lib --with-local-prefix=/tools \
    --enable-clocale=gnu --enable-shared \
    --enable-threads=posix --enable-__cxa_atexit \
    --enable-languages=c,c++ --disable-libstdcxx-pch</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>Test the results</para>

<screen><userinput>make -k check</userinput></screen>

<para>To get a summary of the test suite results, run this:</para>
 
<screen><userinput>../gcc-&gcc-version;/contrib/test_summary</userinput></screen>

<para>For only the summaries, pipe the output through
<userinput>grep -A7 Summ</userinput></para>

<para>Results can be compared to those posted to the gcc-testresults
mailing list to see similar configurations to the one being built. For an example of how
current GCC-&gcc-version; should look on i686-pc-linux-gnu, see
<ulink url="http://gcc.gnu.org/ml/gcc-testresults/2004-11/msg00569.html"/>.</para>

<para>And finally install the package:</para>

<screen><userinput>make install</userinput></screen>

<note><para>At this point it is strongly recommended to repeat the sanity check
we performed earlier in this chapter. Refer back to
<xref linkend="ch-tools-adjusting"/> and repeat the little test compilation. If
the result is wrong, then most likely you forgot to apply the above mentioned
GCC Specs patch.</para></note>
