-<para>Before you start using the LFS book, we should point out that all
|
|
|
-of the commands here assume that you are using the bash shell. If you
|
|
|
-aren't, the commands may work, but we can't guarantee it. If you want a
|
|
|
-simple life, use bash.</para>
|
|
|
-
|
|
|
-<para>Before you can actually start doing something with a package, you need
|
|
|
-to unpack it first. Often the package files are tar'ed and
|
|
|
-gzip'ed or bzip2'ed. We're not going to write down every time how to
|
|
|
-unpack an archive. We'll explain how to do that once, in this
|
|
|
-section.</para>
|
|
|
-
|
|
|
-<para>To start with, change to the $LFS/usr/src directory by running:</para>
|
|
|
-
|
|
|
-<para><screen><userinput>cd $LFS/usr/src</userinput></screen></para>
|
|

|
|
|
-<para>If a file is tar'ed and gzip'ed, it is unpacked by
|
|
|
-running either one of the following two commands, depending on the
|
|
|
-filename:</para>
|
|
|
-
|
|
|
-<para><screen><userinput>tar -xvzf filename.tar.gz</userinput>
|
|
|
-<userinput>tar -xvzf filename.tgz</userinput></screen></para>
|

|
-
|
|
|
-
|
|
|
-<para>If a file is tar'ed and bzip2'ed, it is unpacked by
|
|
|
-running:</para>
|
|
|
-
|
|
|
-<para><screen><userinput>bzcat filename.tar.bz2 | tar -xv</userinput></screen></para>
|
|
|

|
|
|
-<para>Nowadays most tar programs, but not all, are
|
|
|
-patched to be able to use bzip2 files directly. They use either
|
|
|
-the -I, the -y, or the -j parameter, which work the same as the -z
|
|
|
-parameter for handling gzip files. The above construction, however,
|
|
|
-works no matter how your host system decided to patch tar.</para>
|
|
|
-
|
|
|
-<para>If a file is just tar'ed, it is unpacked by running:</para>
|
|
|
-
|
|
|
-<para><screen><userinput>tar -xvf filename.tar</userinput></screen></para>
|
|
|

|
|
|
-<para>When an archive is unpacked, a new directory will be created under the
|
|
|
-current directory (and this book assumes that the archives are unpacked
|
|
|
-under the $LFS/usr/src directory). Please enter that new directory
|
|
|
-before continuing with the installation instructions. Again, every time
|
|
|
-this book is going to install a package, it's up to you to unpack the source
|
|
|
-archive and cd into the newly created directory.</para>
|
|
|
-
|
|
|
-<para>From time to time you will be dealing with single files such as patch
|
|
|
-files. These files are generally gzip'ed or bzip2'ed. Before such files
|
|
|
-can be used they need to be uncompressed.</para>
|
|
|
-
|
|
|
-<para>If a file is gzip'ed, it is unpacked by running:</para>
|
|
|
-
|
|
|
-<para><screen><userinput>gunzip filename.gz</userinput></screen></para>
|
|
|
-
|
|
|
-<para>If a file is bzip2'ed, it is unpacked by running:</para>
|
|
|
-
|
|
|
-<para><screen><userinput>bunzip2 filename.bz2</userinput></screen></para>

|
-<para>After a package has been installed, two things can be done with
|
|
|
-it: either the directory that contains the sources can be deleted, or it
|
|
|
-can be kept. We highly recommend deleting it. If you don't do this and
|
|
|
-try to re-use the same source later on in the book (for example re-using
|
|
|
-the source trees from Chapter 5 in Chapter 6), it may not work
|
|
|
-as you expect it to. Source trees from Chapter 5 will have your host
|
|
|
-distribution's settings, which don't always apply to the LFS system
|
|
|
-after you enter the chroot environment. Even running something like
|
|
|
-<emphasis>make clean</emphasis> doesn't always guarantee a clean source
|
|
|
-tree.</para>
|
|
|
-
|
|
|
-<para>So, save yourself a lot of hassle and just remove the source directory
|
|
|
-immediately after you have installed it, but keep the downloaded tarball
|
|
|
-available for when you need it again.</para>
|
|
|
-
|
|
|
-<para>There is one exception; the kernel source tree. Keep it around as you
|
|
|
-will need it later in this book when building a kernel. Nothing before then
|
|
|
-will use the kernel tree, so the source tree won't be in your way. If,
|
|
|
-however, you are short of disk space, you can remove the kernel tree and
|
|
|
-re-untar it later when required.</para>
