| 50 | <para>To help us find the cause of the problem, both screen output and
|
---|
| 51 | the contents of various files are useful. The screen output from both
|

[2c094d6] | 52 | the ./configure script and the make run can be useful. Don't blindly
|
---|
[1e6acd6] | 53 | include the whole thing but on the other hand, don't include too little.
|

| 54 | As an example, here is some screen output from make:</para>

|

[ddfe603] | 71 |
|
---|
[4e7792e] | 72 | <para>In this case, many people just include the bottom section where it
|

| 73 | says:</para>

|
---|
| 75 | <screen>make [2]: *** [make] Error 1</screen>
|
---|
| 76 |
|
---|
| 77 | <para>and onwards. This isn't enough for us to diagnose the problem because it
|
---|
| 78 | only tells us that <emphasis>something</emphasis> went wrong, not
|
---|
| 79 | <emphasis>what</emphasis> went wrong. The whole section, as in the example
|
---|
| 80 | above, is what should be included to be helpful, because it includes the
|
---|
| 81 | command that was executed and the command's error message(s).</para>

| 95 | <para>Many packages provide a test suite which, depending on the importance
|
---|
| 96 | of the package, we may encourage you to run. Sometimes packages will
|
---|
| 97 | generate false or expected failures. If you encounter these, you can check
|
---|
[35c2fa60] | 98 | the LFS Wiki page at <ulink url="http://wiki.linuxfromscratch.org/"/> to see
|
---|
[2785ba8] | 99 | whether we have already investigated and noted them. If we already know
|
---|
| 100 | about them, then usually there is no need to be concerned.</para>
