| 13 | <para>If an issue or a question is encountered while working through
|
---|
[cff800e] | 14 | this book, please check the FAQ page at <ulink url="&faq-root;#generalfaq"/>.
|
---|
[13a9dc2] | 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:

|

| 20 | <para>If you cannot find your problem listed in the FAQ, search the mailing

|

| 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,
|
---|
[ad3a136] | 26 | we get several support questions every day and many of them can be easily
|
---|
[13a9dc2] | 27 | answered by going to the FAQ and by searching the mailing lists first.
|
---|
[ad3a136] | 28 | So, for us to offer the best assistance possible, you need to do some
|
---|
[13a9dc2] | 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>

| 85 | <para>Both the screen output and the contents of various files are useful

| 87 | the <command>configure</command> script and the <command>make</command>
|
---|
| 88 | run can be helpful. It is not necessary to include the entire output, but
|
---|
| 89 | do include enough of the relevant information. Below is an example of the
|
---|
| 90 | type of information to include from the screen output from

| 91 | <command>make</command>:</para>

|

|

[13a9dc2] | 112 | <para>In this case, many people would just include the bottom

|
---|
| 116 |
|
---|
[13a9dc2] | 117 | <para>This is not enough information to properly diagnose the problem
|
---|
| 118 | because it only notes that something went wrong, not
|
---|
| 119 | <emphasis>what</emphasis> went wrong. The entire section, as in the
|
---|
| 120 | example above, is what should be saved because it includes the command
|

| 121 | that was executed and the associated error message(s).</para>
