10 | <para>If you run into a problem while working through this book, you should
|
---|
11 | first check the FAQ at <ulink url="&faq-root;"/> -- often your question
|
---|
12 | is already answered there. If it is not, you should try to find the source of
|
---|
13 | the problem. The following hint might give you some ideas for your
|
---|
14 | troubleshooting: <ulink url="&hints-root;errors.txt"/>.</para>
|

15 |
|
---|
16 | <para>If all that fails, you will find that most people on IRC and the mailing
|
---|
17 | lists (see <xref linkend="ch-scatter-administrativa"/>) are willing to help
|
---|
18 | you. But to assist them in diagnosing and solving your problem, please include
|

19 | all relevant information in your request for help.</para>

23 |
|

24 | <para>Apart from a brief explanation of the problem you're having, the
|
---|
25 | essential things to include in your request are:</para>
|
---|
26 |
|
---|
27 | <itemizedlist>
|
---|
28 | <listitem><para>the version of the book you are using (being &version;),</para></listitem>
|
---|
29 | <listitem><para>the host distribution and version you are using to create
|
---|
30 | LFS,</para></listitem>
|
---|
31 | <listitem><para>the package or section giving you problems,</para></listitem>
|

32 | <listitem><para>the exact error message or symptom you are receiving,</para></listitem>
|

33 | <listitem><para>whether you have deviated from the book at all.</para></listitem>
|

34 | </itemizedlist>
|
---|
35 |
|
---|
36 | <para>(Note that saying that you've deviated from the book doesn't mean
|
---|
37 | that we won't help you. After all, LFS is about choice. It'll just
|
---|
38 | help us to see other possible causes of your problem.)</para>

|

44 |
|
---|
45 | <para>When something goes wrong during the stage where the configure script
|
---|
46 | is run, look through the <filename>config.log</filename> file. This file
|
---|
47 | may contain errors encountered during configure which weren't printed to
|
---|
48 | the screen. Include those relevant lines if you decide to ask for
|
---|
49 | help.</para>

|

55 |
|
---|
56 | <para>To help us find the cause of the problem, both screen output and
|
---|
57 | the contents of various files are useful. The screen output from both
|
---|
58 | the ./configure script and the make run can be useful. Don't blindly
|
---|
59 | include the whole thing but, on the other hand, don't include too little.
|
---|
60 | As an example, here is some screen output from make:</para>
|
---|
61 |
|
---|
62 | <screen>gcc -DALIASPATH=\"/mnt/lfs/usr/share/locale:.\"
|
---|
63 | -DLOCALEDIR=\"/mnt/lfs/usr/share/locale\" -DLIBDIR=\"/mnt/lfs/usr/lib\"
|
---|
64 | -DINCLUDEDIR=\"/mnt/lfs/usr/include\" -DHAVE_CONFIG_H -I. -I.
|
---|
65 | -g -O2 -c getopt1.c
|
---|
66 | gcc -g -O2 -static -o make ar.o arscan.o commands.o dir.o expand.o file.o
|
---|
67 | function.o getopt.o implicit.o job.o main.o misc.o read.o remake.o rule.o
|
---|
68 | signame.o variable.o vpath.o default.o remote-stub.o version.o opt1.o
|
---|
69 | -lutil job.o: In function `load_too_high':
|
---|
70 | /lfs/tmp/make-3.79.1/job.c:1565: undefined reference to `getloadavg'
|
---|
71 | collect2: ld returned 1 exit status
|
---|
72 | make[2]: *** [make] Error 1
|
---|
73 | make[2]: Leaving directory `/lfs/tmp/make-3.79.1'
|
---|
74 | make[1]: *** [all-recursive] Error 1
|
---|
75 | make[1]: Leaving directory `/lfs/tmp/make-3.79.1'
|
---|
76 | make: *** [all-recursive-am] Error 2</screen>
|
---|
77 |
|
---|
78 | <para>In this case, many people just include the bottom section where it
|
---|
79 | says:</para>
|
---|
80 |
|
---|
81 | <screen>make [2]: *** [make] Error 1</screen>
|
---|
82 |
|
---|
83 | <para>and onwards. This isn't enough for us to diagnose the problem because it
|
---|
84 | only tells us that <emphasis>something</emphasis> went wrong, not
|
---|
85 | <emphasis>what</emphasis> went wrong. The whole section, as in the example
|
---|
86 | above, is what should be included to be helpful, because it includes the
|
---|
87 | command that was executed and the command's error message(s).</para>

|

89 | <para>An excellent article on asking for help on the Internet in general
|
---|
90 | has been written by Eric S. Raymond. It is available online at
|
---|
91 | <ulink url="http://catb.org/~esr/faqs/smart-questions.html"/>.
|
---|
92 | Read and follow the hints in that document and you are much more likely
|
---|
93 | to get a response to start with and also to get the help you actually
|
---|
94 | need.</para>

101 | <para>Many packages provide a test suite which, depending on the importance
|
---|
102 | of the package, we may encourage you to run. Sometimes packages will
|
---|
103 | generate false or expected failures. If you encounter these, you can check
|
---|
104 | the LFS Wiki page at <ulink url="&wiki-root;"/> to see whether we have
|
---|
105 | already noted and investigated them. If we already know
|
---|
106 | about them, then usually there is no need to be concerned.</para>
