[b470bce] | 12 | programs compiled in <xref linkend="chapter-building-system"/>. The programs compiled here are only
|
---|
[673b0d8] | 13 | temporary tools and won't be a part of the final LFS system and by keeping them
|
---|
| 14 | in a separate directory, we can later easily throw them away. This also
|
---|
| 15 | helps prevent them from ending up in your host's production directories

| 18 | <para>Later on you might wish to search through the binaries of your system to
|
---|
| 19 | see what files they make use of or link against. To make this searching easier
|
---|
| 20 | you may want to choose a unique name for the directory in which the temporary
|
---|
| 21 | tools are stored. Instead of the simple <quote>tools</quote> you could use
|
---|
| 22 | something like <quote>tools-for-lfs</quote>. However, you'll need to be careful
|
---|
| 23 | to adjust all references to <quote>tools</quote> throughout the book --
|
---|
| 24 | including those in any patches, notably the GCC Specs Patch.</para>

| 28 | <screen><userinput>mkdir $LFS/tools</userinput></screen>

|
---|
| 31 | your <emphasis>host</emphasis> system. It will point to the directory we just created on the LFS
|
---|
| 32 | partition:</para>

| 34 | <screen><userinput>ln -s $LFS/tools /</userinput></screen>

|

| 37 | has a few syntactic variations, so be sure to check the info page before

[673b0d8] | 42 | and linker will work both in this chapter (when we are still using some tools
