| 14 | will be installed under <filename class="directory">$LFS/tools</filename>
|
|---|
| 15 | to keep them separate from the programs compiled in <xref
|
|---|
| 16 | linkend="chapter-building-system"/>. The programs compiled here are
|
|---|
| 17 | temporary tools and will not be a part of the final LFS system. By keeping
|
|---|
| 18 | these programs in a separate directory, they can easily be discarded later
|
|---|
| 19 | after their use. This also prevents these programs from ending up in the
|
|---|
| 20 | host production directories (easy to do by accident in <xref
|
|---|
| 21 | linkend="chapter-temporary-tools"/>).</para>

| 23 | <para>Create the required directory by running the following as

| 24 | <systemitem class="username">root</systemitem>:</para>

| 26 | <screen><userinput>mkdir -v $LFS/tools</userinput></screen>

| 27 |
|

| 28 | <para>The next step is to create a <filename class="symlink">/tools</filename>
|
|---|
| 29 | symlink on the host system. This will point to the newly-created directory on
|
|---|
| 30 | the LFS partition. Run this command as <systemitem
|
|---|
| 31 | class="username">root</systemitem> as well:</para>
|

| 33 | <screen><userinput>ln -sv $LFS/tools /</userinput></screen>

| 35 | <note>
|
|---|
| 36 | <para>The above command is correct. The <command>ln</command> command
|
|---|
| 37 | has a few syntactic variations, so be sure to check
|
|---|
| 38 | <command>info coreutils ln</command> and <filename>ln(1)</filename>
|
|---|
| 39 | before reporting what you may think is an error.</para>

|
|---|
| 41 |
|
|---|
| 42 | <para>The created symlink enables the toolchain to be compiled so that it
|
|---|
| 43 | always refers to <filename class="directory">/tools</filename>, meaning
|
|---|
| 44 | that the compiler, assembler, and linker will work both in Chapter 5
|
|---|
| 45 | (when we are still using some tools from the host) and in the next (when
|
|---|
| 46 | we are <quote>chrooted</quote> to the LFS partition).</para>
