| 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 -v $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 -v a+wt $LFS/sources</userinput></screen>
