| 40 | <para>It is important that Binutils be the first package compiled
|
---|
| 41 | because both Glibc and GCC perform various tests on the available
|
---|
| 42 | linker and assembler to determine which of their own features to
|
---|
| 43 | enable.</para>
|

| 44 |
|
---|
| 45 | <para>The Binutils documentation recommends building Binutils outside of the
|
---|
| 46 | source directory in a dedicated build directory:</para>

| 51 | <note>
|
---|
| 52 | <para>In order for the SBU values listed in the rest of the book
|
---|
| 53 | to be of any use, measure the time it takes to build this package from
|
---|
| 54 | the configuration, up to and including the first install. To achieve
|
---|
| 55 | this easily, wrap the three commands in a <command>time</command>
|
---|
| 56 | command like this: <userinput>time { ./configure ... && make
|

|

| 92 | Expect, and DejaGNU) is not yet in place. The benefits of running the
