<para>The steps in this section are optional. If your LFS partition is rather
|
|
small, you will be glad to learn that you can throw away some unnecessary
|
|
things. The executables and libraries you have built so far contain about 130 MB
|
|
of unneeded debugging symbols. Remove those symbols like this:</para>
|
|
|
|
<screen><userinput>strip --strip-unneeded /tools/{,s}bin/*
|
|
strip --strip-debug /tools/lib/*</userinput></screen>
|
|
|
|
<para>The first of the above commands will skip some twenty files, reporting
|
|
that it doesn't recognize their file format. Most of them are scripts instead
|
|
of binaries.</para>
|
|
|
|
<para>Take care <emphasis>not</emphasis> to use
|
|
<userinput>--strip-unneeded</userinput> on the libraries -- they would be
|
|
destroyed and you would have to build Glibc all over again.</para>
|
|
|
|
<para>To save another couple of megabytes, you can throw away all the
|
|
documentation:</para>
|
|
|
|
<screen><userinput>rm -rf /tools/{,share/}{doc,info,man}</userinput></screen>
|
|
|
|
<para>You will now need to have at least 850 MB of free space on your LFS
|
|
filesystem to be able to build and install Glibc in the next phase. If you can
|
|
build and install Glibc, you can build and install the rest too.</para>
