13 <para>If an issue or a question is encountered while working through
14 this book, check the FAQ page at <ulink url="&faq-root;#generalfaq"/>.
15 Questions are often already answered there. If your question is not
16 answered on this page, try to find the source of the problem. The
17 following hint will give you some guidance for troubleshooting:
18 <ulink url="&hints-root;errors.txt"/>.</para>
19
20 <para>We also have a wonderful CLFS community that is willing to offer
21 assistance through the mailing lists and IRC (see the <xref
22 linkend="ch-intro-resources"/> section of this book). However, we
23 get several support questions everyday and many of them can be easily
24 answered by going to the FAQ and by searching the mailing lists first.
25 So for us to offer the best assistance possible, you need to do some
26 research on your own first. This allows us to focus on the more unusual
27 support needs. If your searches do not produce a solution, please include
28 all relevant information (mentioned below) in your request for help.</para>

31 <title>Things to Mention</title>
32
33 <para>Apart from a brief explanation of the problem being experienced,
34 the essential things to include in any request for help are:</para>
35
36 <itemizedlist>
37 <listitem>
38 <para>The version of the book being used (in this case
39 &version;)</para>
40 </listitem>
41 <listitem>
42 <para>The host distribution and version being used to
43 create CLFS.</para>
44 </listitem>
45 <listitem>
46 <para>The architecture of the host and target.</para>
47 </listitem>
48 <listitem>
49 <para>The value of the $CLFS_HOST, $CLFS_TARGET, $BUILD32, and $BUILD64
50 environment variables.</para>
51 </listitem>
52 <listitem>
53 <para>The package or section in which the problem was encountered.</para>
54 </listitem>
55 <listitem>
56 <para>The exact error message or symptom received. See <xref
57 linkend="ch-intro-askforhelp-compilation-problems"/> below for an
58 example.</para>
59 </listitem>
60 <listitem>
61 <para>Note whether you have deviated from the book at all. A package
62 version change or even a minor change to any command is considered
63 deviation.</para>
64 </listitem>
65 </itemizedlist>
66
67 <note>
68 <para>Deviating from this book does <emphasis>not</emphasis>
69 mean that we will not help you. After all, the CLFS project is
70 about personal preference. Be upfront about any changes to
71 the established procedure&mdash;this helps us evaluate and determine
72 possible causes of your problem.</para>

78 <title>Configure Script Problems</title>
79
80 <para>If something goes wrong while running the <command>configure</command>
81 script, review the <filename>config.log</filename> file. This file may
82 contain the errors you encountered during <command>configure</command>.
83 It often logs errors that may have not been printed to the screen. Include
84 only the <emphasis>relevant</emphasis> lines if you need to ask for
85 help.</para>

90 <title>Compilation Problems</title>
91
92 <para>Both the screen output and the contents of various files are
93 useful in determining the cause of compilation problems. The screen output
94 from the <command>configure</command> script and the
95 <command>make</command> run can be helpful. It is not necessary to
96 include the entire output, but do include enough of the relevant
97 information. Below is an example of the type of information to include
98 from the screen output from <command>make</command>:</para>
99
100<screen><computeroutput>gcc -DALIASPATH=\"/mnt/clfs/usr/share/locale:.\"
101-DLOCALEDIR=\"/mnt/clfs/usr/share/locale\"
102-DLIBDIR=\"/mnt/clfs/usr/lib\"
103-DINCLUDEDIR=\"/mnt/clfs/usr/include\" -DHAVE_CONFIG_H -I. -I.
104-g -O2 -c getopt1.c
105gcc -g -O2 -static -o make ar.o arscan.o commands.o dir.o
106expand.o file.o function.o getopt.o implicit.o job.o main.o
107misc.o read.o remake.o rule.o signame.o variable.o vpath.o
108default.o remote-stub.o version.o opt1.o
109-lutil job.o: In function `load_too_high':
110/clfs/tmp/make-3.79.1/job.c:1565: undefined reference
111to `getloadavg'
112collect2: ld returned 1 exit status
113make[2]: *** [make] Error 1
114make[2]: Leaving directory `/clfs/tmp/make-3.79.1'
115make[1]: *** [all-recursive] Error 1
116make[1]: Leaving directory `/clfs/tmp/make-3.79.1'
117make: *** [all-recursive-am] Error 2</computeroutput></screen>
118
119 <para>In this case, many people would just include the bottom
120 section:</para>
121
122<screen><computeroutput>make [2]: *** [make] Error 1</computeroutput></screen>
123
124 <para>This is not enough information to properly diagnose the problem
125 because it only notes that something went wrong, not
126 <emphasis>what</emphasis> went wrong. The entire section, as in the
127 example above, is what should be saved because it includes the command
128 that was executed and the associated error message(s).</para>
129
130 <para>An excellent article about asking for help on the Internet is
131 available online at <ulink
132 url="http://catb.org/~esr/faqs/smart-questions.html"/>. Read and
133 follow the hints in this document to increase the likelihood of getting
134 the help you need.</para>
