| 11 | <para>All programs compiled in <xref linkend="chapter-temporary-tools"/> will be installed under <filename
|
|---|
| 12 | class="directory">$LFS/tools</filename> to keep them separate from the
|
|---|
| 13 | programs compiled in <xref linkend="chapter-building-system"/>. The programs compiled here are only
|
|---|
| 14 | temporary tools and won't be a part of the final LFS system and by keeping them
|
|---|
| 15 | in a separate directory, we can later easily throw them away. This also
|
|---|
| 16 | helps prevent them from ending up in your host's production directories
|
|---|
| 17 | (easy to do in <xref linkend="chapter-temporary-tools"/>), which could be a very bad thing.</para>
|

| 18 |
|
|---|
| 19 | <para>Later on you might wish to search through the binaries of your system to
|
|---|
| 20 | see what files they make use of or link against. To make this searching easier
|
|---|
| 21 | you may want to choose a unique name for the directory in which the temporary
|
|---|
| 22 | tools are stored. Instead of the simple <quote>tools</quote> you could use
|
|---|
| 23 | something like <quote>tools-for-lfs</quote>. However, you'll need to be careful
|
|---|
| 24 | to adjust all references to <quote>tools</quote> throughout the book --
|
|---|
| 25 | including those in any patches, notably the GCC Specs Patch.</para>
|
|---|
| 26 |
|
|---|
| 27 | <para>Create the required directory by running the following:</para>
|
|---|
| 28 |
|
|---|
| 29 | <screen><userinput>mkdir $LFS/tools</userinput></screen>
|
|---|
| 30 |
|
|---|
| 31 | <para>The next step is to create a <filename>/tools</filename> symlink on
|
|---|
| 32 | your <emphasis>host</emphasis> system. It will point to the directory we just created on the LFS
|
|---|
| 33 | partition:</para>
|
|---|
| 34 |
|
|---|
| 35 | <screen><userinput>ln -s $LFS/tools /</userinput></screen>
|
|---|
| 36 |
|
|---|
| 37 | <note><para>The above command is correct. The <command>ln</command> command
|
|---|
| 38 | has a few syntactic variations, so be sure to check the info page before
|
|---|
| 39 | reporting what you may think is an error.</para></note>
|
|---|
| 40 |
|
|---|
| 41 | <para>The created symlink enables us to compile our toolchain so that it always
|
|---|
| 42 | refers to <filename class="directory">/tools</filename>, meaning that the compiler, assembler
|
|---|
| 43 | and linker will work both in this chapter (when we are still using some tools
|
|---|
| 44 | from the host) <emphasis>and</emphasis> in the next (when we are <quote>chrooted</quote> to
|
|---|
| 45 | the LFS partition).</para>
