| 43 | <para>If your LFS partition is rather small, you will be glad to learn that you
|
|---|
| 44 | can throw away some unnecessary things. The executables and libraries you have
|
|---|
| 45 | built so far contain about 130 MB of unneeded debugging symbols. Remove those
|
|---|
| 46 | symbols like this:</para>
|
|---|
| 47 |
|
|---|
| 48 | <para><screen><userinput>strip --strip-unneeded /tools/{,s}bin/*
|
|---|
| 49 | strip --strip-debug /tools/lib/*</userinput></screen></para>
|
|---|
| 50 |
|
|---|
| 51 | <para>The first of the above commands will skip some twenty files, reporting
|
|---|
| 52 | that it doesn't recognize their file format. Most of them are scripts instead
|
|---|
| 53 | of binaries.</para>
|
|---|
| 54 |
|
|---|
| 55 | <para>Take care <emphasis>not</emphasis> to use
|
|---|
| 56 | <userinput>--strip-unneeded</userinput> on the libraries -- they would be
|
|---|
| 57 | destroyed and you would have to build Glibc all over again.</para>
|
|---|
| 58 |
|
|---|
| 59 | <para>To save another couple of megabytes, you can throw away the documentation
|
|---|
| 60 | and some of the bigger unneeded programs:</para>
|
|---|
| 61 |
|
|---|
| 62 | <para><screen><userinput>rm -r /tools/share/{doc,info,man}
|
|---|
| 63 | rm /tools/bin/{addr2line,gprof,nm,size,strings,strip}</userinput></screen></para>
|
|---|
| 64 |
|
|---|
| 65 | <para>You will now need to have at least 700 MB of free space on your LFS
|
|---|
| 66 | filesystem to be able to build and install Glibc in the next phase.</para>
