| 13 | <para>This chapter shows how to compile and install a minimal Linux
|
|---|
| 14 | system. This system will contain just enough tools to start
|
|---|
| 15 | constructing the final LFS system in <xref
|
|---|
| 16 | linkend="chapter-building-system"/> and allow a working environment
|
|---|
| 17 | with more user convenience than a minimum environment would.</para>
|
|---|
| 18 |
|
|---|
| 19 | <para>The tools in this chapter are cross-compiled using the toolchain in /cross-tools. The files compiled in this chapter will be installed under the
|
|---|
| 20 | <filename class="directory">$LFS/tools</filename> directory to keep
|
|---|
| 21 | them separate from the files installed in <xref
|
|---|
| 22 | linkend="chapter-building-system"/> and the host production directories.
|
|---|
| 23 | Since the packages compiled here are temporary, we do not want them to
|
|---|
| 24 | pollute the soon-to-be LFS system.</para>
|

| 25 |
|

| 26 | <para>Check one last time that the <envar>LFS</envar> environment
|
|---|
| 27 | variable is set up properly:</para>

| 29 | <screen><userinput>echo $LFS</userinput></screen>

|

| 31 | <para>Make sure the output shows the path to the LFS partition's mount
|
|---|
| 32 | point, which is <filename class="directory">/mnt/lfs</filename>, using
|
|---|
| 33 | our example.</para>
|

| 34 |
|

| 35 | <para>During this section of the build you will see several WARNING
|
|---|
| 36 | messages like the one below. It is safe to ignore these messages.</para>
|

| 37 |
|
|---|
| 38 | <blockquote><screen><computeroutput>configure: WARNING: If you wanted to set the --build type, don't use --host.
|
|---|
| 39 | If a cross compiler is detected then cross compile mode will be used.</computeroutput></screen></blockquote>
