13  <para>This chapter shows you how to create cross platform tools.</para>
15  <para>If for some reason you have to stop and come back later, remember
16  to use the <command>su - clfs</command> command, and it will setup the
17  build environment that you left.</para>

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>
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>
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&mdash;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>
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>
