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