| 6 | <para>This package is known to behave badly when you have changed its default
|
|---|
| 7 | optimization flags (including the -march and -mcpu options). Therefore, if
|
|---|
| 8 | you have defined any environment variables that override default
|
|---|
| 9 | optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting or
|
|---|
| 10 | modifying them when building binutils.</para>
|

| 11 |
|

| 12 | <para>It is recommended by the Binutils installation documentation to build
|

| 13 | Binutils outside of the source directory in a dedicated directory:</para>

| 25 | <listitem><para><userinput>--disable-nls</userinput>: This option disables
|

| 26 | internationalization (also known as i18n). We don't need this for our

|

| 38 | <listitem><para><userinput>LDFLAGS="-all-static"</userinput>: This is
|
|---|
| 39 | how we tell Binutils that all programs should be statically linked. Setting
|
|---|
| 40 | the <emphasis>LDFLAGS</emphasis> variable is the common way of specifying we
|

| 41 | want a static link to take place, however, its value and the way it is set
|
|---|
| 42 | is not always the same. You'll see with the remaining packages that there
|

| 43 | are different ways of setting up the <emphasis>LDFLAGS</emphasis>
