15 | We strongly discourage posting your issues building one LFS package
|
---|
16 | directly onto the upstream support channel, without discussing via
|
---|
17 | a LFS support channel listed in <xref linkend="ch-intro-resources"/>
|
---|
18 | first. Doing so is often quite inefficient because the upstream
|
---|
19 | maintainers are rarely familiar with LFS building procedure. Even if
|
---|
20 | you've really hit an upstream issue, the LFS community can still help
|
---|
21 | to isolate the information wanted by the upstream maintainers and make
|
---|
22 | a proper report.
|
---|
23 | </para>
|
---|
24 |
|
---|
25 | <para>
|
---|
26 | If you must ask a question directly via an upstream support channel,
|
---|
27 | you shall at least note that many upstream projects have the support
|
---|
28 | channels separated from the bug tracker. The <quote>bug</quote>
|
---|
29 | reports for asking questions are considered invalid and may annoy
|
---|
30 | upstream developers for these projects.

32 | </note>
|

33 |
|
---|
34 | <para>If an issue or a question is encountered while working through
|
---|
35 | this book, please check the FAQ page at <ulink url="&faq-root;#generalfaq"/>.
|
---|
36 | Questions are often already answered there. If your question is not
|
---|
37 | answered on that page, try to find the source of the problem. The
|
---|
38 | following hint will give you some guidance for troubleshooting:
|
---|
39 | <ulink url="&hints-root;errors.txt"/>.</para>
|
---|
40 |
|
---|
41 | <para>If you cannot find your problem listed in the FAQ, search the mailing
|
---|
42 | lists at <ulink url="&lfs-root;search.html"/>.</para>
|
---|
43 |
|
---|
44 | <para>We also have a wonderful LFS community that is willing to offer
|
---|
45 | assistance through the mailing lists and IRC (see the <xref
|
---|
46 | linkend="ch-intro-resources"/> section of this book). However,
|
---|
47 | we get several support questions every day, and many of them could have been easily
|
---|
48 | answered by going to the FAQ or by searching the mailing lists first.
|
---|
49 | So, for us to offer the best assistance possible, you should first do some
|
---|
50 | research on your own. That allows us to focus on the more unusual
|
---|
51 | support needs. If your searches do not produce a solution, please include
|
---|
52 | all the relevant information (mentioned below) in your request for help.</para>

57 | <para>Apart from a brief explanation of the problem being experienced,

58 | any request for help should include these essential things:</para>

81 | <note>

82 | <para>Deviating from this book does <emphasis>not</emphasis> mean that
|

83 | we will not help you. After all, LFS is about personal preference.
|
---|
84 | Being up-front about any changes to the established procedure helps us
|
---|
85 | evaluate and determine possible causes of your problem.</para>

|

103 |
|

104 | <para>Both the screen output and the contents of various files are useful
|
---|
105 | in determining the cause of compilation problems. The screen output from
|
---|
106 | the <command>configure</command> script and the <command>make</command>
|
---|
107 | run can be helpful. It is not necessary to include the entire output, but
|
---|
108 | do include all of the relevant information. Here is an example of the
|
---|
109 | type of information to include from the <command>make</command> screen
|
---|
110 | output.</para>

129 | make: *** [all-recursive-am] Error 2</computeroutput></screen>
|
---|
130 |
|
---|
131 | <para>In this case, many people would just include the bottom
|
---|
132 | section:</para>
|
---|
133 |
|
---|
134 | <screen><computeroutput>make [2]: *** [make] Error 1</computeroutput></screen>
|
---|
135 |
|
---|
136 | <para>This is not enough information to diagnose the problem,
|
---|
137 | because it only notes that something went wrong, not
|
---|
138 | <emphasis>what</emphasis> went wrong. The entire section, as in the
|
---|
139 | example above, is what should be saved because it includes the command
|
---|
140 | that was executed and all the associated error messages.</para>
|
---|
141 |
|
---|
142 | <para>An excellent article about asking for help on the Internet is
|
---|
143 | available online at <ulink
|
---|
144 | url="http://catb.org/~esr/faqs/smart-questions.html"/>. Read this document,
|

145 | and follow the hints. Doing so will increase the likelihood of getting
|

146 | the help you need.</para>
