<sect2><title>Installation of Binutils</title>
|
|
|
|
<note><para>The testsuite for Binutils in this chapter is considered
|
|
<emphasis>critical</emphasis>. Do not skip it under any circumstances.</para>
|
|
</note>
|
|
|
|
<para>This package is known to behave badly when you have changed its
|
|
default optimization flags (including the -march and -mcpu options).
|
|
Therefore, if you have defined any environment variables that override
|
|
default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
|
|
or modifying them when building Binutils.</para>
|
|
|
|
<para>It is recommended by the Binutils installation documentation to build
|
|
Binutils outside of the source directory:</para>
|
|
|
|
<para><screen><userinput>mkdir ../binutils-build
|
|
cd ../binutils-build</userinput></screen></para>
|
|
|
|
<para>Now prepare Binutils for compilation:</para>
|
|
|
|
<para><screen><userinput>../binutils-&binutils-version;/configure \
|
|
--prefix=/usr --enable-shared</userinput></screen></para>
|
|
|
|
<para>Compile the package:</para>
|
|
|
|
<para><screen><userinput>make tooldir=/usr</userinput></screen></para>
|
|
|
|
<para>Normally, the <emphasis>tooldir</emphasis> (the directory where the
|
|
executables end up) is set to $(exec_prefix)/$(target_alias), which expands
|
|
into, for example, <filename>/usr/i686-pc-linux-gnu</filename>. Since we only
|
|
build for our own system, we don't need this target specific directory in
|
|
<filename>/usr</filename>. That setup would be used if the system was used to
|
|
cross-compile (for example compiling a package on an Intel machine that
|
|
generates code that can be executed on PowerPC machines).</para>
|
|
|
|
<para>Test the results:</para>
|
|
|
|
<para><screen><userinput>make check</userinput></screen></para>
|
|
|
|
<para>Install the package:</para>
|
|
|
|
<para><screen><userinput>make tooldir=/usr install</userinput></screen></para>
