4 | <title>Installation of Binutils</title>
|
---|
5 |
|
---|
6 | <para>It is important that Binutils be the first package to get compiled,
|
---|
7 | because both Glibc and GCC perform various tests on the available linker and
|
---|
8 | assembler to determine which of their own features to enable.</para>
|
---|
9 |
|
---|
10 | <para>This package is known to behave badly when you have changed its default
|
---|
11 | optimization flags (including the -march and -mcpu options). Therefore, if
|
---|
12 | you have defined any environment variables that override default
|
---|
13 | optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting or
|
---|
14 | modifying them when building Binutils.</para>
|
---|
15 |
|
---|
16 | <para>It is recommended by the Binutils installation documentation to build
|
---|
17 | Binutils outside of the source directory in a dedicated directory:</para>
|
---|
18 |
|
---|
19 | <para><screen><userinput>mkdir ../binutils-build
|
---|
20 | cd ../binutils-build</userinput></screen></para>
|
---|
21 |
|
---|
22 | <para>Next, prepare Binutils to be compiled:</para>
|
---|
23 |
|
---|
24 | <para><screen><userinput>../binutils-&binutils-version;/configure \
|
---|
25 | --prefix=/stage1 --disable-nls</userinput></screen></para>
|
---|
26 |
|
---|
27 | <para>The meaning of the configure switches is:</para>
|
---|
28 |
|
---|
29 | <itemizedlist>
|
---|
30 | <listitem><para><userinput>--prefix=/stage1</userinput>: This tells the
|
---|
31 | configure script to prepare to install the Binutils programs in the
|
---|
32 | <filename>/stage1</filename> directory.</para></listitem>
|
---|
33 | <listitem><para><userinput>--disable-nls</userinput>: This disables
|
---|
34 | internationalization (a word often shortened to i18n). We don't need this
|
---|
35 | for our static programs and <emphasis>nls</emphasis> often causes problems
|
---|
36 | when linking statically.</para></listitem>
|
---|
37 | </itemizedlist>
|
---|
38 |
|
---|
39 | <para>Continue with compiling the package:</para>
|
---|
40 |
|
---|
41 | <para><screen><userinput>make configure-host
|
---|
42 | make LDFLAGS="-all-static"</userinput></screen></para>
|
---|
43 |
|
---|
44 | <para>The meaning of the make option is:</para>
|
---|
45 |
|
---|
46 | <itemizedlist>
|
---|
47 | <listitem><para><userinput>LDFLAGS="-all-static"</userinput>: This tells
|
---|
48 | the linker that all the Binutils programs should be linked
|
---|
49 | statically.</para></listitem>
|
---|
50 | </itemizedlist>
|
---|
51 |
|
---|
52 | <para>And install the package:</para>
|
---|
53 |
|
---|
54 | <para><screen><userinput>make install</userinput></screen></para>
|
---|
55 |
|
---|
56 | <para>Now already prepare the linker for the "locking in" of
|
---|
57 | <emphasis>glibc</emphasis> later on:</para>
|
---|
58 |
|
---|
59 | <para><screen><userinput>make -C ld clean
|
---|
60 | make -C ld LIB_PATH=/stage1/lib</userinput></screen></para>
|
---|
61 |
|
---|
62 | <para><emphasis>Do not yet remove</emphasis> the binutils-* directories.
|
---|
63 | We will need them again a bit further on in this chapter.</para>
