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>If you cannot find your problem listed in the FAQ, search the mailing
21 lists at <ulink url="&lfs-root;search.html"/>.</para>
22
23 <para>We also have a wonderful LFS community that is willing to offer
24 assistance through the mailing lists and IRC (see the <xref
25 linkend="ch-intro-resources"/> section of this book). However,
26 we get several support questions every day and many of them can be easily
27 answered by going to the FAQ and by searching the mailing lists first.
28 So, for us to offer the best assistance possible, you need to do some
29 research on your own first. That allows us to focus on the more unusual
30 support needs. If your searches do not produce a solution, please include
31 all relevant information (mentioned below) in your request for help.</para>

34 <title>Things to Mention</title>
35
36 <para>Apart from a brief explanation of the problem being experienced,
37 the essential things to include in any request for help are:</para>
38
39 <itemizedlist>
40 <listitem>
41 <para>The version of the book being used (in this case &version;)</para>
42 </listitem>
43 <listitem>
44 <para>The host distribution and version being used to create LFS</para>
45 </listitem>
46 <listitem>
47 <para>The package or section the problem was encountered in</para>
48 </listitem>
49 <listitem>
50 <para>The exact error message or symptom being received</para>
51 </listitem>
52 <listitem>
53 <para>Note whether you have deviated from the book at all </para>
54 </listitem>
55 </itemizedlist>
56
57 <note>
58 <para>Deviating from this book does <emphasis>not</emphasis> mean that
59 we will not help you. After all, LFS is about personal preference.
60 Being upfront about any changes to the established procedure helps us
61 evaluate and determine possible causes of your problem.</para>

69 <para>If something goes wrong while running the <command>configure</command>
70 script, review the <filename>config.log</filename> file. This file may
71 contain errors encountered during <command>configure</command> which were
72 not printed to the screen. Include the <emphasis>relevant</emphasis> lines
73 if you need to ask for help.</para>

80 <title>Compilation Problems</title>
81
82 <para>Both the screen output and the contents of various files are useful
83 in determining the cause of compilation problems. The screen output from
84 the <command>configure</command> script and the <command>make</command>
85 run can be helpful. It is not necessary to include the entire output, but
86 do include enough of the relevant information. Below is an example of the
87 type of information to include from the screen output from
88 <command>make</command>:</para>
89
90<screen><computeroutput>gcc -DALIASPATH=\"/mnt/lfs/usr/share/locale:.\"
91-DLOCALEDIR=\"/mnt/lfs/usr/share/locale\"
92-DLIBDIR=\"/mnt/lfs/usr/lib\"
93-DINCLUDEDIR=\"/mnt/lfs/usr/include\" -DHAVE_CONFIG_H -I. -I.
94-g -O2 -c getopt1.c
95gcc -g -O2 -static -o make ar.o arscan.o commands.o dir.o
96expand.o file.o function.o getopt.o implicit.o job.o main.o
97misc.o read.o remake.o rule.o signame.o variable.o vpath.o
98default.o remote-stub.o version.o opt1.o
99-lutil job.o: In function `load_too_high':
100/lfs/tmp/make-3.79.1/job.c:1565: undefined reference
101to `getloadavg'
102collect2: ld returned 1 exit status
103make[2]: *** [make] Error 1
104make[2]: Leaving directory `/lfs/tmp/make-3.79.1'
105make[1]: *** [all-recursive] Error 1
106make[1]: Leaving directory `/lfs/tmp/make-3.79.1'
107make: *** [all-recursive-am] Error 2</computeroutput></screen>
108
109 <para>In this case, many people would just include the bottom
110 section:</para>
111
112<screen><computeroutput>make [2]: *** [make] Error 1</computeroutput></screen>
113
114 <para>This is not enough information to properly diagnose the problem
115 because it only notes that something went wrong, not
116 <emphasis>what</emphasis> went wrong. The entire section, as in the
117 example above, is what should be saved because it includes the command
118 that was executed and the associated error message(s).</para>
119
120 <para>An excellent article about asking for help on the Internet is
121 available online at <ulink
122 url="http://catb.org/~esr/faqs/smart-questions.html"/>. Read and
123 follow the hints in this document to increase the likelihood of getting
124 the help you need.</para>
