<title>Installation of Binutils</title>
|
|
|
|
<para>It is important that Binutils be the first package compiled
|
|
because both Glibc and GCC perform various tests on the available
|
|
linker and assembler to determine which of their own features to
|
|
enable.</para>
|
|
|
|
<para>The Binutils documentation recommends building Binutils outside of the
|
|
source directory in a dedicated build directory:</para>
|
|
|
|
<screen><userinput>mkdir -v ../binutils-build
|
|
cd ../binutils-build</userinput></screen>
|
|
|
|
<note><para>In order for the SBU values listed in the rest of the book
|
|
to be of any use, measure the time it takes to build this package from
|
|
the configuration, up to and including the first install. To achieve
|
|
this easily, wrap the three commands in a <command>time</command>
|
|
command like this: <userinput>time { ./configure ... && make
|
|
&& make install; }</userinput>.</para></note>
|
|
|
|
<para>Now prepare Binutils for compilation:</para>
|
|
|
|
<screen><userinput>../binutils-&binutils-version;/configure --prefix=/tools --disable-nls</userinput></screen>
|
|
|
|
<para>The meaning of the configure options:</para>
|
|
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term><parameter>--prefix=/tools</parameter></term>
|
|
<listitem><para>This tells the configure script to prepare to install the Binutils
|
|
programs in the <filename class="directory">/tools</filename> directory.</para></listitem>
|
|
</varlistentry>
|
|
|
|
<varlistentry>
|
|
<term><parameter>--disable-nls</parameter></term>
|
|
<listitem><para>This disables internationalization as i18n is not needed for the
|
|
temporary tools.</para></listitem>
|
|
</varlistentry>
|
|
</variablelist>
|
|
|
|
<para>Continue with compiling the package:</para>
|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<para>Compilation is now complete. Ordinarily we would now run the
|
|
test suite, but at this early stage the test suite framework (Tcl,
|
|
Expect, and DejaGNU) is not yet in place. The benefits of running the
|
|
tests at this point are minimal since the programs from this
|
|
first pass will soon be replaced by those from the second.</para>
|
|
|
|
<para>Install the package:</para>
|
|
|
|
<screen><userinput>make install</userinput></screen>
|
|
|
|
<para>Next, prepare the linker for the <quote>Adjusting</quote> phase
|
|
later on:</para>
|
|
|
|
<screen><userinput>make -C ld clean
|
|
make -C ld LIB_PATH=/tools/lib</userinput></screen>
|
|
|
|
<para>The meaning of the make parameters:</para>
|
|
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term><parameter>-C ld clean</parameter></term>
|
|
<listitem><para>This tells the make program to remove all compiled
|
|
files in the <filename class="directory">ld</filename>
|
|
subdirectory.</para></listitem>
|
|
</varlistentry>
|
|
|
|
<varlistentry>
|
|
<term><parameter>-C ld LIB_PATH=/tools/lib</parameter></term>
|
|
<listitem><para>This option rebuilds everything in the
|
|
<filename class="directory">ld</filename> subdirectory. Specifying
|
|
the <envar>LIB_PATH</envar> Makefile variable on the command
|
|
line allows us to override the default value
|
|
and point it to the temporary tools location. The value of this variable
|
|
specifies the linker's default library search path. This preparation
|
|
is used later in the chapter.</para></listitem>

|
|
|

<warning><para><emphasis>Do not</emphasis> remove the Binutils

build and source directories yet. These will be needed again in their

current state later in this chapter.</para></warning>
