| 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>Create a directory called
|
|---|
| 30 | <filename class="directory">${CLFS}/sources</filename> and use it to store
|
|---|
| 31 | your sources and patches. All packages should be compiled there as well.
|
|---|
| 32 | Using any other location for compiling may have unexpected results.</para>
|
|---|
| 33 |
|
|---|
| 34 | <para>To create this directory, execute, as user <systemitem
|
|---|
| 35 | class="username">root</systemitem>, the following command before
|
|---|
| 36 | starting the download session:</para>
|
|---|
| 37 |
|
|---|
| 38 | <screen><userinput>mkdir -v ${CLFS}/sources</userinput></screen>
|
|---|
| 39 |
|
|---|
| 40 | <para>Make this directory writable and sticky. When a directory is
|
|---|
| 41 | marked <quote>sticky</quote>, that means that even if multiple users have
|
|---|
| 42 | write permission on that directory, any file within that directory can only be
|
|---|
| 43 | deleted or modified by its owner. The following command will enable the
|
|---|
| 44 | write and sticky modes:</para>
|
|---|
| 45 |
|
|---|
| 46 | <screen><userinput>chmod -v a+wt ${CLFS}/sources</userinput></screen>
