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

<note><para>It's worth pointing out that the Binutils test suite we run in this
section is considered not as important as the one we run in Chapter 6.</para>
</note>

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

<para><screen><userinput>mkdir ../binutils-build
cd ../binutils-build</userinput></screen></para>

<para>Now prepare Binutils to be compiled:</para>

<para><screen><userinput>../binutils-&binutils-version;/configure --prefix=/tools \
&nbsp;&nbsp;&nbsp;&nbsp;--enable-shared --with-lib-path=/tools/lib</userinput></screen></para>

<para>The meaning of the new configure option:</para>

<itemizedlist>
<listitem><para><userinput>--with-lib-path=/tools/lib</userinput>: This tells
the configure script to specify the default library search path. We don't want
the library search path to contain library directories from the host
system.</para></listitem>
</itemizedlist>

<para>Before starting to build Binutils, remember to unset any environment
variables that override the default optimization flags.</para>

<para>Compile the package:</para>

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

<para>Test the results (there should be no unexpected failures here, expected
failures are fine):</para>

<para><screen><userinput>make check</userinput></screen></para>

<para>Unfortunately, there is no easy way to view the test results summary like
there was for the previous GCC package. However, if a failure occurs here, it
should be easy to spot. The output shown will contain something like:</para>

<blockquote><screen>make[1]: *** [check-binutils] Error 2</screen></blockquote>

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

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

<para>Now prepare Binutils for the re-adjusting of the toolchain in the next
chapter:</para>

<para><screen><userinput>make -C ld clean
make -C ld LIB_PATH=/usr/lib:/lib</userinput></screen></para>

<warning><para>Do not yet remove the Binutils source and build directories.
We'll need these directories again in the next chapter in the state they are in
now.</para></warning>
