| 13 | <para>The steps in this section are optional, but if the LFS partition is
|
|---|
| 14 | rather small, it is beneficial to learn that unnecessary items can be removed.
|

| 15 | The executables and libraries built so far contain about 70 MB of unneeded
|
|---|
| 16 | debugging symbols. Remove those symbols with:</para>

|

| 18 | <screen><userinput>strip --strip-debug /tools/lib/*
|

| 19 | strip --strip-unneeded /tools/{,s}bin/*</userinput></screen>

| 21 | <para>These commands will skip a number of files, reporting that it does not
|
|---|
| 22 | recognize their file format. Most of these are scripts instead of binaries.</para>

| 23 |
|

| 24 | <para>Take care <emphasis>not</emphasis> to use
|
|---|
| 25 | <parameter>--strip-unneeded</parameter> on the libraries. The static
|
|---|
| 26 | ones would be destroyed and the toolchain packages would need to be
|
|---|
| 27 | built all over again.</para>

| 29 | <para>To save more, remove the documentation:</para>

| 33 | <para>At this point, you should have at least 3 GB of free space in
|
|---|
| 34 | <envar>$LFS</envar> that can be used to build and install Glibc and Gcc in
|
|---|
| 35 | the next phase. If you can build and install Glibc, you can build and install
|

| 36 | the rest too.</para>
