| 23 | <para>Before issuing the build instructions for a package, the package
|
|---|
| 24 | should be unpacked as user <systemitem class="username">clfs</systemitem>,
|
|---|
| 25 | and a <command>cd</command> into the created directory should be
|
|---|
| 26 | performed. The build instructions assume that the <command>bash</command>
|
|---|
| 27 | shell is in use.</para>

|

|

| 30 | <para>Several of the packages are patched before compilation, but only
|
|---|
| 31 | when the patch is needed to circumvent a problem or supply a default
|
|---|
| 32 | configuration. Warning messages about <emphasis>offset</emphasis> or
|
|---|
| 33 | <emphasis>fuzz</emphasis> may also be encountered when applying a patch.
|
|---|
| 34 | Do not worry about these warnings, as the patch was still successfully
|
|---|
| 35 | applied.</para>
|
|---|
| 36 |
|
|---|
| 37 | <para>During the compilation of most packages, there will be several
|
|---|
| 38 | warnings that scroll by on the screen. These are normal and can safely
|
|---|
| 39 | be ignored. These warnings are as they appear—warnings about
|
|---|
| 40 | deprecated, but not invalid, use of the C or C++ syntax. C standards
|
|---|
| 41 | change fairly often, and some packages still use the older standard.
|
|---|
| 42 | This is not a problem, but does prompt the warning.</para>

| 45 | <para>After installing each package, both in this and the next chapters,
|
|---|
| 46 | delete its source and build directories, unless specifically instructed
|

| 47 | otherwise.</para>
