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="&lfs-root;lfs/packages.html"/>.</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">$LFS/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 LFS 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 $LFS/sources</userinput></screen> |
---|
43 | |
---|
44 | <para>Make this directory writable and sticky. <quote>Sticky</quote> |
---|
45 | means that even if multiple users have write permission on a |
---|
46 | directory, only the owner of a file can delete the file within a |
---|
47 | sticky directory. The following command will enable the write and |
---|
48 | sticky modes:</para> |
---|
49 | |
---|
50 | <screen><userinput>chmod a+wt $LFS/sources</userinput></screen> |
