| 10 | <para>The steps in this section are optional, but if the LFS partition
|
|---|
| 11 | is rather small, it is beneficial to learn that unnecessary items can
|
|---|
| 12 | be removed. The executables and libraries built so far contain about
|
|---|
| 13 | 130 MB of unneeded debugging symbols. Remove those symbols
|
|---|
| 14 | with:</para>
|

| 15 |
|

| 16 | <screen><userinput>strip --strip-debug /tools/lib/*
|

| 17 | strip --strip-unneeded /tools/{,s}bin/*</userinput></screen>

| 19 | <para>The last of the above commands will skip some twenty files,
|
|---|
| 20 | reporting that it does not recognize their file format. Most of these
|
|---|
| 21 | are scripts instead of binaries.</para>
|

| 22 |
|

| 23 | <para>Take care <emphasis>not</emphasis> to use
|
|---|
| 24 | <parameter>--strip-unneeded</parameter> on the libraries. The static
|
|---|
| 25 | ones would be destroyed and the toolchain packages would need to be
|
|---|
| 26 | built all over again.</para>

| 28 | <para>To save another 30 MB, remove the documentation:</para>

| 32 | <para>There will now be at least 850 MB of free space on the LFS file
|

| 33 | system that can be used to build and install Glibc in the next phase.

| 34 | If you can build and install Glibc, you can build and install the rest
|
