| 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>
|
---|
| 17 |
|
---|
| 18 | <screen><userinput>strip --strip-debug /tools/lib/*
|
---|
| 19 | strip --strip-unneeded /tools/{,s}bin/*</userinput></screen>
|

|
---|
| 21 | <para>The last of the above commands will skip some twenty files,
|
---|
| 22 | reporting that it does not recognize their file format. Most of these
|
---|
| 23 | are scripts instead of binaries.</para>
|
---|
| 24 |
|
---|
| 25 | <para>Take care <emphasis>not</emphasis> to use
|
---|
| 26 | <parameter>--strip-unneeded</parameter> on the libraries. The static
|
---|
| 27 | ones would be destroyed and the toolchain packages would need to be
|
---|
| 28 | built all over again.</para>
|
---|
| 29 |
|
---|
| 30 | <para>To save nearly 20 MB more, remove the documentation:</para>
|
---|
| 31 |
|
---|
| 32 | <screen><userinput>rm -rf /tools/{info,man}</userinput></screen>
|
---|
| 33 |
|
---|
| 34 | <para>At this point, you should have at least 850 MB of free space in
|
---|
| 35 | <envar>$LFS</envar> that can be used to build and install Glibc in the
|
---|
| 36 | next phase. If you can build and install Glibc, you can build and install
|
---|
| 37 | the rest too.</para>
