<para>This package is known to have issues when its default
|
|
optimization flags (including the <parameter>-march</parameter> and
|
|
<parameter>-mcpu</parameter> options) are changed. If any environment
|
|
variables that override default optimizations have been defined, such
|
|
as <envar>CFLAGS</envar> and <envar>CXXFLAGS</envar>,
|
|
unset them when building Binutils.</para>
|
|
|
|
<para>Create a separate build directory again:</para>

<screen><userinput>mkdir ../binutils-build

<listitem><para>This tells the configure script to specify the library

search path during the compilation of Binutils, resulting in <filename

the host.</para></listitem>

<para>Compile the package:</para>

<para>Compilation is now complete. As discussed earlier, running the

test suite is not mandatory for the temporary tools here in this

chapter. To run the Binutils test suite anyway, issue the following

command:</para>

<screen><userinput>make check</userinput></screen>

|
|
<para>Install the package:</para>

<screen><userinput>make install</userinput></screen>

<para>Now prepare the linker for the <quote>Re-adjusting</quote> phase in the next

chapter:</para>

build directories yet. These directories will be needed again in the next

|
chapter in their current state.</para></warning>
