46 <note><para>Go back and re-read the notes in the previous section.
47 Understanding the notes labeled important will save you a lot
48 of problems later.</para></note>
50 <para>It is important that Binutils be the first package compiled
51 because both Glibc and GCC perform various tests on the available
52 linker and assembler to determine which of their own features to
55 <para>The Binutils documentation recommends building Binutils outside of the
56 source directory in a dedicated build directory:</para>
58 <screen><userinput remap="pre">mkdir -v ../binutils-build
59 cd ../binutils-build</userinput></screen>
62 <para>In order for the SBU values listed in the rest of the book
63 to be of any use, measure the time it takes to build this package from
64 the configuration, up to and including the first install. To achieve
65 this easily, wrap the three commands in a <command>time</command>
66 command like this: <userinput>time { ./configure ... && make
67 && make install; }</userinput>.</para>
70 <note><para>The approximate build SBU values and required disk space
71 in Chapter 5 does not include test suite data.</para></note>
73 <para>Now prepare Binutils for compilation:</para>
75 <screen><userinput remap="configure">../binutils-&binutils-version;/configure \
76 --target=$LFS_TGT --prefix=/tools \
77 --disable-nls --disable-werror</userinput></screen>
80 <title>The meaning of the configure options:</title>
83 <term><envar>--target=$LFS_TGT</envar></term>
85 <para>Because the machine description in the <envar>LFS_TGT</envar>
86 variable is slightly different than the value returned by the
87 <command>config.guess</command> script, this switch will tell the
88 <command>configure</command> script to adjust Binutil's build system
89 for building a cross linker. </para>
94 <term><parameter>--prefix=/tools</parameter></term>
96 <para>This tells the configure script to prepare to install the
97 Binutils programs in the <filename class="directory">/tools</filename>
103 <term><parameter>--disable-nls</parameter></term>
105 <para>This disables internationalization as i18n is not needed for the
106 temporary tools.</para>
111 <term><parameter>--disable-werror</parameter></term>
113 <para>This prevents the build from stopping in the event that there
114 are warnings from the host's compiler.</para>
120 <para>Continue with compiling the package:</para>
122 <screen><userinput remap="make">make</userinput></screen>
124 <para>Compilation is now complete. Ordinarily we would now run the
125 test suite, but at this early stage the test suite framework (Tcl,
126 Expect, and DejaGNU) is not yet in place. The benefits of running the
127 tests at this point are minimal since the programs from this
128 first pass will soon be replaced by those from the second.</para>
130 <para>If building on x86_64, create a symlink to ensure the sanity of
131 the toolchain:</para>
133 <screen><userinput remap="install">case $(uname -m) in
134 x86_64) mkdir -v /tools/lib && ln -sv lib /tools/lib64 ;;
135 esac</userinput></screen>
137 <para>Install the package:</para>
139 <screen><userinput remap="install">make install</userinput></screen>
