[b28fd35]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.
[0b37960]15 The executables and libraries built so far contain about 70 MB of unneeded
[b28fd35]16 debugging symbols. Remove those symbols with:</para>
[3d36131c]17
[673b0d8]18<screen><userinput>strip --strip-debug /tools/lib/*
[e2c4848]19/usr/bin/strip --strip-unneeded /tools/{,s}bin/*</userinput></screen>
[673b0d8]20
[182d5d3]21 <para>These commands will skip a number of files, reporting that it does not
[e2c4848]22 recognize their file format. Most of these are scripts instead of binaries.
23 Also use the system strip command to include the strip binary in /tools.</para>
[81fd230]24
[b28fd35]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>
[81fd230]29
[776f1dc]30 <para>To save more, remove the documentation:</para>
[3d36131c]31
[776f1dc]32<screen><userinput>rm -rf /tools/{,share}/{info,man,doc}</userinput></screen>

[aca25d4]34 <para>At this point, you should have at least 3 GB of free space in
35 <envar>$LFS</envar> that can be used to build and install Glibc and Gcc in
36 the next phase. If you can build and install Glibc, you can build and install
[0b37960]37 the rest too.</para>
