6 | <para>This package is known to behave badly when you have changed its default
|
---|
7 | optimization flags (including the -march and -mcpu options). Therefore, if
|
---|
8 | you have defined any environment variables that override default
|
---|
9 | optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting or
|
---|
10 | modifying them when building binutils.</para>
|
---|
11 |
|
---|
12 | <para>It is recommended by the Binutils installation documentation to build
|
---|
13 | Binutils outside of the source directory in a dedicated directory:</para>
|
---|
14 |
|
---|
15 | <para><screen><userinput>mkdir ../binutils-build
|
---|
16 | cd ../binutils-build</userinput></screen></para>
|
---|
17 |
|
---|
18 | <para>Next, prepare Binutils to be compiled:</para>
|
---|
19 |
|
---|
20 | <para><screen><userinput>../binutils-&binutils-version;/configure \
|
---|
21 | --prefix=/stage1 --disable-nls</userinput></screen></para>
|
---|
22 |
|
---|
23 | <para>The meaning of the (new) configure switches are:</para>
|
---|
24 |
|
---|
25 | <itemizedlist>
|
---|
26 | <listitem><para><userinput>--disable-nls</userinput>: This option disables
|
---|
27 | internationalization (also known as i18n). We don't need this for our
|
---|
28 | static programs and nls often causes problems when you're linking
|
---|
29 | statically.</para></listitem>
|
---|
30 | </itemizedlist>
|
---|
31 |
|
---|
32 | <para>Continue with compiling the package:</para>
|
---|
33 |
|
---|
34 | <para><screen><userinput>make LDFLAGS="-all-static"</userinput></screen></para>
|
---|
35 |
|
---|
36 | <para>The meaning of the make option is:</para>
|
---|
37 |
|
---|
38 | <itemizedlist>
|
---|
39 | <listitem><para><userinput>LDFLAGS="-all-static"</userinput>: This is
|
---|
40 | how we tell Binutils that all programs should be statically linked. Setting
|
---|
41 | the <emphasis>LDFLAGS</emphasis> variable is the common way of specifying we
|
---|
42 | want a static link to take place, however, its value and the way it is set
|
---|
43 | is not always the same. You'll see with the remaining packages that there
|
---|
44 | are different ways of setting up the <emphasis>LDFLAGS</emphasis>
|
---|
45 | variable.</para></listitem>
|
---|
46 | </itemizedlist>
|
---|
47 |
|
---|
48 | <para>And finish off installing the package:</para>
|
---|
49 |
|
---|
50 | <para><screen><userinput>make install</userinput></screen></para>
|
---|
51 |
|
---|
52 | <para><screen><userinput>make -C ld clean
|
---|
53 | make -C ld LIB_PATH=/stage1/lib</userinput></screen></para>
|
---|
54 |
|
---|
55 | <para>Do not remove the binutils-* directories. We need them again
|
---|
56 | later on in this chapter.</para>
