7 | Relay Chat (IRC) and on the mailing lists are willing to help you. An

16 | <para>Apart from a brief explanation of the problem you're having, the
|
---|
17 | essential things to include in your request are:</para>
|

18 |
|
---|
19 | <itemizedlist>
|
---|
20 | <listitem><para>the version of the book you are using (being &version;),</para></listitem>

|

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

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

24 | </itemizedlist>
|

25 |
|
---|
26 | <para>(Note that saying that you've deviated from the book doesn't mean
|
---|
27 | that we won't help you. After all, LFS is about choice. It'll just
|
---|
28 | help us to see other possible causes of your problem.)</para>

35 | <para>When something goes wrong during the stage where the configure
|
---|
36 | script is run, look at the last lines of the
|
---|
37 | <filename>config.log</filename>. This file may contain errors
|
---|
38 | encountered during configure which weren't printed to the screen.
|
---|
39 | Include those relevant lines if you decide to ask for help.</para>

|

45 |
|
---|
46 | <para>To help us find the cause of the problem, both screen output and
|
---|
47 | the contents of various files are useful. The screen output from both
|
---|
48 | the ./configure script and the make run can be useful. Don't blindly
|
---|
49 | include the whole thing but on the other hand, don't include too little.
|
---|
50 | As an example, here is some screen output from make:</para>
|
---|
51 |
|
---|
52 | <para><screen>gcc -DALIASPATH=\"/mnt/lfs/usr/share/locale:.\"
|
---|
53 | -DLOCALEDIR=\"/mnt/lfs/usr/share/locale\" -DLIBDIR=\"/mnt/lfs/usr/lib\"
|
---|
54 | -DINCLUDEDIR=\"/mnt/lfs/usr/include\" -DHAVE_CONFIG_H -I. -I.
|
---|
55 | -g -O2 -c getopt1.c
|
---|
56 | gcc -g -O2 -static -o make ar.o arscan.o commands.o dir.o expand.o file.o
|
---|
57 | function.o getopt.o implicit.o job.o main.o misc.o read.o remake.o rule.o
|
---|
58 | signame.o variable.o vpath.o default.o remote-stub.o version.o opt1.o
|
---|
59 | -lutil job.o: In function `load_too_high':
|
---|
60 | /lfs/tmp/make-3.79.1/job.c:1565: undefined reference to `getloadavg'
|
---|
61 | collect2: ld returned 1 exit status
|
---|
62 | make[2]: *** [make] Error 1
|
---|
63 | make[2]: Leaving directory `/lfs/tmp/make-3.79.1'
|
---|
64 | make[1]: *** [all-recursive] Error 1
|
---|
65 | make[1]: Leaving directory `/lfs/tmp/make-3.79.1'
|
---|
66 | make: *** [all-recursive-am] Error 2</screen></para>
|
---|
67 |
|
---|
68 | <para>In this case, many people just include the bottom section where it
|
---|
69 | says <screen>make [2]: *** [make] Error 1</screen> and onwards. This
|
---|
70 | isn't enough for us to diagnose the problem because it only tells us
|
---|
71 | that <emphasis>something</emphasis> went wrong, not
|
---|
72 | <emphasis>what</emphasis> went wrong. The whole section, as
|
---|
73 | in the example above, is what should be included to be helpful, because it
|
---|
74 | includes the command that was executed and the command's error
|
---|
75 | message(s).</para>

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