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

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

  46. <title>Configure Script Problems</title>
  47. <para>If something goes wrong while running the <command>configure</command>
  48. script, review the <filename>config.log</filename> file. This file may
  49. contain errors encountered during <command>configure</command> which were not
  50. printed to the screen. Include the <emphasis>relevant</emphasis> lines if you
  51. need to ask for help.</para>
  52. </sect2>

  54. <title>Compilation Problems</title>
  55. <para>Both the screen output and the contents of various files are
  56. useful in determining the cause of compilation problems. The screen output
  57. from the <command>configure</command> script and the
  58. <command>make</command> run can be helpful. It
  59. is not necessary to include the entire output, but do include enough
  60. of the relevant information. Below is an example of the type of
  61. information to include from the screen output from <command>make</command>:</para>
  62. <screen><computeroutput>gcc -DALIASPATH=\"/mnt/lfs/usr/share/locale:.\"
  63. -DLOCALEDIR=\"/mnt/lfs/usr/share/locale\"
  64. -DLIBDIR=\"/mnt/lfs/usr/lib\"
  65. -DINCLUDEDIR=\"/mnt/lfs/usr/include\" -DHAVE_CONFIG_H -I. -I.
  66. -g -O2 -c getopt1.c
  67. gcc -g -O2 -static -o make ar.o arscan.o commands.o dir.o
  68. expand.o file.o function.o getopt.o implicit.o job.o main.o
  69. misc.o read.o remake.o rule.o signame.o variable.o vpath.o
  70. default.o remote-stub.o version.o opt1.o
  71. -lutil job.o: In function `load_too_high':
  72. /lfs/tmp/make-3.79.1/job.c:1565: undefined reference
  73. to `getloadavg'
  74. collect2: ld returned 1 exit status
  75. make[2]: *** [make] Error 1
  76. make[2]: Leaving directory `/lfs/tmp/make-3.79.1'
  77. make[1]: *** [all-recursive] Error 1
  78. make[1]: Leaving directory `/lfs/tmp/make-3.79.1'
  79. make: *** [all-recursive-am] Error 2</computeroutput></screen>
  80. <para>In this case, many people would just include the bottom
  81. section:</para>
  82. <screen><computeroutput>make [2]: *** [make] Error 1</computeroutput></screen>
  83. <para>This is not enough information to properly diagnose the problem
  84. because it only notes that something went wrong, not
  85. <emphasis>what</emphasis> went wrong. The entire section, as in the
  86. example above, is what should be saved because it includes the command
  87. that was executed and the associated error message(s).</para>
  88. <para>An excellent article about asking for help on the Internet is
  89. available online at <ulink
  90. url="http://catb.org/~esr/faqs/smart-questions.html"/>. Read and
  91. follow the hints in this document to increase the likelihood of getting
  92. the help you need.</para>
