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>
|
---|
27 |
|

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
|
---|
35 | too.</para>
