<title>Installation of Binutils</title>
|
|
|
|
<para>This package is known to behave badly when you have changed its default
|
|
optimization flags (including the -march and -mcpu options). Binutils is
|
|
best left alone. Therefore, if you have defined any environment variables
|
|
that override default optimizations, such as CFLAGS and CXXFLAGS, we
|
|
recommend unsetting or modifying them when building binutils. You have been
|
|
warned.</para>
|
|
|
|
<para>It is recommended by the Binutils installation documentation to build
|
|
Binutils outside of the source directory in a dedicated directory:</para>
|
|
|
|
<para><screen><userinput>mkdir ../binutils-build
|
|
cd ../binutils-build</userinput></screen></para>
|
|
|
|
<para>Next, prepare Binutils to be compiled:</para>
|
|
|
|
<para><screen><userinput>../binutils-&binutils-version;/configure --prefix=$LFS/static --disable-nls</userinput></screen></para>
|
|
|
|
<para>The meaning of the (new) configure switches are:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem><para><userinput>--disable-nls:</userinput> This option disables
|
|
internationalization (also known as i18n). We don't need this for our
|
|
static programs and nls often causes problems when you're linking
|
|
statically.</para></listitem>
|
|
</itemizedlist>
|
|
|
|
<para>We'll finish off by compiling and installing the package:</para>
|
|
|
|
<para><screen><userinput>make LDFLAGS="-all-static" &&
|
|
make install</userinput></screen></para>
|
|
|
|
<para>The meaning of the make option is:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem><para><userinput>make LDFLAGS="-all-static":</userinput> This is
|
|
how we tell Binutils that all programs should be statically linked. Setting
|
|
the <emphasis>LDFLAGS</emphasis> variable is the common way of specifying we
|
|
want a static link to take place, however, its value and the way it is set
|
|
is not always the same. You'll see with the remaining packages that there
|
|
are different ways of setting up the <emphasis>LDFLAGS</emphasis>
|
|
variable.</para></listitem>
