| 23 | <para>Before issuing the build instructions for a package, the package |
|---|
| 24 | should be unpacked, and a <command>cd</command> into the created |
|---|
| 25 | directory should be performed.</para> |
|---|
| 26 | </important> |
|---|
| 27 | |
|---|
| 28 | <para>Several of the packages are patched before compilation, but only |
|---|
| 29 | when the patch is needed to circumvent a problem. A patch is often needed |
|---|
| 30 | in both this and the next chapters, but sometimes in only one or the other. |
|---|
| 31 | Therefore, do not be concerned if instructions for a downloaded patch seem |
|---|
| 32 | to be missing. 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> |
|---|
| 43 | |
|---|
| 44 | <important> |
|---|
| 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. Deleting the sources prevents mis-configuration |
|---|
| 48 | when the same package is reinstalled later.</para> |
