---|
| 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 |
---|
[35b75e6] | 27 | url="&packages-root;"/>.</para> |
---|
[3f8be484] | 28 | |
---|
[686949f] | 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> |
---|
[3f8be484] | 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 | |

---|
[3f8be484] | 39 | |
---|
[35b75e6] | 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> |

---|
[83ba36f2] | 48 | <para>You can download all needed packages and patches into this directory |
---|
[24b004c] | 49 | either by using the links on the following pages in this section, or by passing |

[348e150] | 50 | the <ulink url="../dl.list">download list</ulink> to <command>wget</command>:</para> |

| 54 | <para>Verification of downloaded packages can be done by downloading the |
