| 5 | <para>This package is known to behave badly when you have changed its
|
|---|
| 6 | default optimization flags (including the -march and -mcpu options). Binutils
|
|---|
| 7 | is best left alone. Therefore, if you have defined any environment variables
|
|---|
| 8 | that override default optimizations, such as CFLAGS and CXXFLAGS, we
|
|---|
| 9 | recommend unsetting or modifying them when building binutils. You have
|
|---|
| 10 | been warned.</para>
|
|---|
| 11 |
|
|---|
| 12 | <para>It is recommended by the Binutils installation documentation to build
|
|---|
| 13 | Binutils outside of the source directory. Create the build directory:</para>
|
|---|
| 14 |
|
|---|
| 15 | <para><screen><userinput>mkdir ../binutils-build &&
|
|---|
| 16 | cd ../binutils-build</userinput></screen></para>
|
|---|
| 17 |
|
|---|
| 18 | <para>Next, prepare Binutils to be compiled:</para>
|
|---|
| 19 |
|
|---|
| 20 | <para><screen><userinput>../binutils-&binutils-version;/configure --prefix=/usr --enable-shared</userinput></screen></para>
|
|---|
| 21 |
|
|---|
| 22 | <para>Continue with compiling the package:</para>
|
|---|
| 23 |
|
|---|
| 24 | <para><screen><userinput>make tooldir=/usr</userinput></screen></para>
|
|---|
| 25 |
|
|---|
| 26 | <para>Normally, the <emphasis>tooldir</emphasis> (the directory where the
|
|---|
| 27 | executables end up) is set to $(exec_prefix)/$(target_alias) which expands
|
|---|
| 28 | into, for example, /usr/i686-pc-linux-gnu. Since we only build for our
|
|---|
| 29 | own system, we don't need this target specific directory in /usr. That
|
|---|
| 30 | setup would be used if the system was used to cross-compile (for example
|
|---|
| 31 | compiling a package on the Intel machine that generates code that can be
|
|---|
| 32 | executed on Apple PowerPC machines).</para>
|
|---|
| 33 |
|
|---|
| 34 | <para>Install the package:</para>
|
|---|
| 35 |
|
|---|
| 36 | <para><screen><userinput>make tooldir=/usr install</userinput></screen></para>
|
|---|
| 37 |
|
|---|
| 38 | <para>Install the info pages:</para>
|
|---|
| 39 |
|
|---|
| 40 | <para><screen><userinput>make tooldir=/usr install-info</userinput></screen></para>
|
|---|
| 41 |
|
|---|
| 42 | <para>Some packages require the <emphasis>libiberty</emphasis> header
|
|---|
| 43 | in order to build. To honor those packages, install the file:</para>
|
|---|
| 44 |
|
|---|
| 45 | <para><screen><userinput>cp ../binutils-&binutils-version;/include/libiberty.h /usr/include</userinput></screen></para>
