13  <para>This chapter includes a list of packages that need to be downloaded
14  for building a basic Linux system. The listed version numbers correspond
15  to versions of the software that are known to work, and this book is based
16  on their use. We highly recommend not using newer versions because the
17  build commands for one version may not work with a newer version. The
18  newest package versions may also have problems that require work-arounds.
19  These work-arounds will be developed and stabilized in the development
20  version of the book.</para>
21
22  <para>Download locations may not always be accessible. If a download
23  location has changed since this book was published, Google (<ulink
24  url="http://www.google.com/"/>) provides a useful search engine for
25  most packages. If this search is unsuccessful, try one of the
26  alternative means of downloading discussed at <ulink
27  url="&packages-root;"/>.</para>
28
29  <para>Downloaded packages and patches will need to be stored somewhere
30  that is conveniently available throughout the entire build. A working
31  directory is also required to unpack the sources and build them.
32  <filename class="directory">$CLFS/sources</filename> can be used both
33  as the place to store the tarballs and patches and as a working
34  directory. By using this directory, the required elements will be
35  located on the CLFS partition and will be available during all stages
36  of the building process.</para>
37
38  <para>To create this directory, execute, as user <systemitem
39  class="username">root</systemitem>, the following command before
40  starting the download session:</para>
41
42<screen><userinput>mkdir -v $CLFS/sources</userinput></screen>
43
44  <para>Make this directory writable and sticky. When a directory is
45  marked <quote>sticky</quote>, that means that even if multiple users have
46  write permission on that directory, any file within that directory can only be
47  deleted or modified by its owner. The following command will enable the
48  write and sticky modes:</para>
49
50<screen><userinput>chmod -v a+wt $CLFS/sources</userinput></screen>
