[03735e97] | 16 | <title>General Libraries</title>
|
---|
[8e75f8b9] | 17 |
|
---|
[03735e97] | 18 | <para>Libraries contain code which is often required by more than
|
---|
| 19 | one program. This has the advantage that each program doesn't need to
|
---|
| 20 | duplicate code (and risk introducing bugs), it just has to call
|
---|
| 21 | functions from the libraries installed on the system. The most obvious
|
---|
[74390482] | 22 | example of a set of libraries is <application>Glibc</application> which is
|
---|
| 23 | installed during the LFS book. This contains all of the
|
---|
[03735e97] | 24 | <application>C</application> library functions which programs use.</para>
|
---|
[8e75f8b9] | 25 |
|
---|
[74390482] | 26 | <para>There are two types of libraries: static and shared. Shared libraries
|
---|
[03735e97] | 27 | (usually <filename>libXXX.so</filename>) are loaded into memory from the shared
|
---|
| 28 | copy at runtime (hence the name). Static libraries (<filename>libXXX.a
|
---|
[74390482] | 29 | </filename>) are actually linked into the program executable file itself, thus
|
---|
| 30 | making the program file larger. Quite often, you will find both static and
|
---|
[03735e97] | 31 | shared copies of the same library on your system.</para>
|
---|
[8e75f8b9] | 32 |
|
---|
[03735e97] | 33 | <para>Generally, you only need to install libraries when you are
|
---|
| 34 | installing software that needs the functionality they supply. In
|
---|
[74390482] | 35 | the BLFS book, each package is presented with a list of
|
---|
| 36 | (known) dependencies. Thus, you can figure out which libraries you need to
|
---|
| 37 | have before installing that program. If you are installing something without
|
---|
| 38 | using BLFS instructions, usually the <filename>README</filename> or
|
---|
| 39 | <filename>INSTALL</filename> file will contain
|
---|
[03735e97] | 40 | details of the program's requirements.</para>
|
---|
[8e75f8b9] | 41 |
|
---|
| 42 | <para>There are certain libraries which nearly <emphasis>everyone</emphasis>
|
---|
[ec64d28] | 43 | will need at some point. In this chapter these and some others are listed and
|
---|
| 44 | it is explained why you may want to install them.</para>
