| 9 | <para>This package is known to behave badly when you have changed its
|
|---|
| 10 | default optimization flags (including the -march and -mcpu options).
|
|---|
| 11 | Therefore, if you have defined any environment variables that override
|
|---|
| 12 | default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
|
|---|
| 13 | or modifying them when building Binutils.</para>

| 15 | <para>The Binutils documentation recommends building Binutils outside of the
|
|---|
| 16 | source directory in a dedicated build directory:</para>
|

| 17 |
|

| 18 | <para><screen><userinput>mkdir ../binutils-build
|
|---|
| 19 | cd ../binutils-build</userinput></screen></para>

| 21 | <para>Now prepare Binutils for compilation:</para>
|
|---|
| 22 |
|
|---|
| 23 | <para><screen><userinput>../binutils-&binutils-version;/configure \
|
|---|
| 24 | --prefix=/usr --enable-shared</userinput></screen></para>

| 26 | <para>Compile the package:</para>
|

| 27 |

|---|
| 28 | <para><screen><userinput>make tooldir=/usr</userinput></screen></para>
|

| 29 |
|
|---|
| 30 | <para>Normally, the <emphasis>tooldir</emphasis> (the directory where the
|
|---|
| 31 | executables end up) is set to $(exec_prefix)/$(target_alias), which expands
|
|---|
| 32 | into, for example, <filename>/usr/i686-pc-linux-gnu</filename>. Since we only
|
|---|
| 33 | build for our own system, we don't need this target specific directory in
|
|---|
| 34 | <filename>/usr</filename>. That setup would be used if the system was used to
|
|---|
| 35 | cross-compile (for example compiling a package on an Intel machine that
|
|---|
| 36 | generates code that can be executed on PowerPC machines).</para>
