4 | <para>This package is known to behave badly when you have changed its default
|
---|
5 | optimization flags (including the -march and -mcpu options). Binutils is
|
---|
6 | best left alone. Therefore, if you have defined any environment variables
|
---|
7 | that override default optimizations, such as CFLAGS and CXXFLAGS, we
|
---|
8 | recommend unsetting or modifying them when building binutils. You have been
|
---|
9 | warned.</para>
|
---|
10 |
|
---|
11 | <para>It is recommended by the Binutils installation documentation to build
|
---|
12 | Binutils outside of the source directory in a dedicated directory:</para>

---|
13 |
|
---|
14 | <para><screen><userinput>mkdir ../binutils-build
|
---|
15 | cd ../binutils-build</userinput></screen></para>
|
---|
16 |
|
---|
17 | <para>Next, prepare Binutils to be compiled:</para>
|
---|
18 |
|
---|
19 | <para><screen><userinput>../binutils-&binutils-version;/configure --prefix=$LFS/static --disable-nls</userinput></screen></para>
|
---|
20 |
|
---|
21 | <para>The meaning of the (new) configure switches are:</para>
|
---|
22 |
|
---|
23 | <itemizedlist>
|
---|
24 | <listitem><para><userinput>--disable-nls:</userinput> This option disables
|
---|
25 | internationalization (also known as i18n). We don't need this for our
|
---|
26 | static programs and nls often causes problems when you're linking
|
---|
27 | statically.</para></listitem>
|
---|
28 | </itemizedlist>
|
---|
29 |
|
---|
30 | <para>We'll finish off by compiling and installing the package:</para>
|
---|
31 |
|
---|
32 | <para><screen><userinput>make LDFLAGS="-all-static" &&
|
---|
33 | make install</userinput></screen></para>
|
---|
34 |
|
---|
35 | <para><emphasis>make LDFLAGS="-all-static"</emphasis> is how we tell
|
---|
36 | Binutils that all programs should be statically linked. Setting the
|
---|
37 | <emphasis>LDFLAGS</emphasis> variable is the common way of specifying we
|
---|
38 | want a static link to take place, however, its value and the way it is set
|
---|
39 | is not always the same. You'll see with the remaining packages that there
|
---|
40 | are different ways of setting up the <emphasis>LDFLAGS</emphasis>
|
---|
41 | variable.</para>
