13 | <para>All programs compiled in <xref linkend="chapter-cross-tools"/> will
|
---|
14 | be installed under <filename class="directory">$LFS/cross-tools</filename>
|
---|
15 | to keep them separate from the host programs. The programs compiled here are
|
---|
16 | cross tools and will not be a part of the final LFS system. By keeping these
|
---|
17 | programs in a separate directory, they can easily be discarded later after
|
---|
18 | their use.</para>
|

19 |
|
---|
20 | <para>Create the required directory by running the following as
|
---|
21 | the <systemitem class="username">lfs</systemitem> user:</para>
|
---|
22 |
|
---|
23 | <screen><userinput>install -d $LFS/cross-tools</userinput></screen>
|
---|
24 |
|
---|
25 | <para>The next step is to create a <filename
|
---|
26 | class="symlink">/cross-tools</filename> symlink on the host system.
|
---|
27 | This will point to the newly-created directory in your home directory.
|
---|
28 | Since normal users will not have permissions to write to the root tree,
|
---|
29 | we need to exit the <command>su</command> and run the symlink command as
|
---|
30 | <systemitem class="username">root</systemitem>:</para>
|
---|
31 |
|
---|
32 | <screen><userinput>ln -s $LFS/cross-tools /</userinput></screen>
|
---|
33 |
|
---|
34 | <para>The created symlink enables the toolchain to be compiled so that
|
---|
35 | it always refers to <filename class="directory">/cross-tools</filename>,
|
---|
36 | meaning that the compiler, assembler, and linker will be avaialble for
|
---|
37 | use later if some unforseen circumstances happen.</para>
