44 | <title>Installation of Binutils</title>
|

45 |
|
---|
46 | <para>It is important that Binutils be the first package compiled
|
---|
47 | because both Glibc and GCC perform various tests on the available
|
---|
48 | linker and assembler to determine which of their own features to
|
---|
49 | enable.</para>
|
---|
50 |
|
---|
51 | <para>Binutils does not recognize versions of Texinfo newer than 4.9. Fix
|
---|
52 | this issue by applying the following patch:</para>

53 |

---|
54 | <screen><userinput remap="pre">patch -Np1 -i ../&binutils-configure-patch;</userinput></screen>
|
---|
55 |
|
---|
56 | <para>The Binutils documentation recommends building Binutils outside of the
|
---|
57 | source directory in a dedicated build directory:</para>
|
---|
58 |
|
---|
59 | <screen><userinput remap="pre">mkdir -v ../binutils-build

62 | <note>
|
---|
63 | <para>In order for the SBU values listed in the rest of the book
|
---|
64 | to be of any use, measure the time it takes to build this package from
|
---|
65 | the configuration, up to and including the first install. To achieve
|
---|
66 | this easily, wrap the three commands in a <command>time</command>
|
---|
67 | command like this: <userinput>time { ./configure ... && make

68 | && make install; }</userinput>.</para>
