43 |

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

48 |
|

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

56 | <para>In order for the SBU values listed in the rest of the book
|
---|
57 | to be of any use, measure the time it takes to build this package from
|
---|
58 | the configuration, up to and including the first install. To achieve
|
---|
59 | this easily, wrap the three commands in a <command>time</command>
|

60 | command like this: <userinput>time { ./configure ... && make

94 | <para>Compilation is now complete. Ordinarily we would now run the

95 | test suite, but at this early stage the test suite framework (Tcl,

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

97 | tests at this point are minimal since the programs from this
